Narcotic "Allergies"


morphineNice little “clinical pearl” review article from about opioid allergies. Seems that they aren’t as common as some patients would have us believe.

It would also seem that if the adverse reactions to opioids are due to histamine release that administering the opioids with an antihistamine such as Phenergan, Vistaril, or Benadryl would serve both to stop the “allergic” reaction and to enhance the effect of the pain medication. Just be careful giving the Phenergan … at least IV.

I often have luck giving opioid agonist/antagonist medications such as Nubain, Stadol or Buprenex to patients who describe horrific allergies to every medication except their narcotic du jour.

Opioid Allergy
True anaphylactic reactions to opioids are very rare. When patients say they are allergic to an opiod, it is much more likely that the patient has experienced GI upset or a pseudoallergy.
Flushing, itching, hives, and sweating, especially itching or flushing at the injection site only, suggests a pseudoallergy due to histamine release, a pharmacologic side effect of some opioids. Codeine, morphine, and meperidine are the opioids most commonly associated with pseudoallergy. Use of a more potent opioid is less likely to result in histamine release.
The potency of opioids, from lower to higher:
meperidine < codeine < morphine < hydrocodone < oxycodone < hydromorphone < fentanyl
If the patient describes a true allergy to an opiate, then an opioid in a chemical class different from the one to which the patient reacted may be used with close monitoring:
Phenylpiperidines: meperidine (Demerol), fentanyl (Duragesic, Actiq, Sublimaze), sufentanil (Sufenta)
Diphenylheptanes: methadone (Dolophine), propoxyphene (Darvon)
Morphine group: morphine, codeine, hydrocodone (Vicodin, Lorcet), oxycodone (Percocet, OxyContin), oxymorphone (Numorphan), hydromorphone (Dilaudid), nalbuphine (Nubain), butorphanol (Stadol), pentazocine (Talwin)

  1. I’m on an opiate-blocker (Revia — no I’m not a heroin addict!!)…how do you guys medicate for that?

    Depends on the cause of the pain. There are options.
    NSAIDs for acute pain. Antidepressants. Neuro meds. Sedatives. Benadryl can be used in place of lidocaine. Local anesthetic patches for localized pain. Infusion pumps or nerve blocks for chronic pain. Work with your doc or hook up with a pain clinic if it’s a chronic problem.

  2. Thanks for the review! I’m surprised Demerol is at the bottom! Why do people love it so much? (It sure worked for me!).

  3. Demerol is a horrible drug for so many reasons. From my own observations, it seems to be better at providing a high than acting as a true analgesic. There’s unpredictability in the kinetics of its active metabolites, and concerns about it’s ability to futz around with one’s seizure threshold, though for abusers it’s fantastic because it doesn’t give the giveaway pinpoint pupils of narcotic (over)use. Oh, and that whole thing about using it in biliary colic because it might cause less spasm of the sphincter of Oddi? Rubbish… besides, the same can be said for Fentanyl and Dilaudid.

    Great reference, Whitecoat.

  4. What do you use for people who cannot use opiods? My mom goes psycho whenever she is given any kind of opiods; getting her through the week after her knee replacement was not fun.

    Hmmm. Toradol – but everyone gets that. Sometimes sedating psych meds such as Elavil will help. If there is a neurogenic component to the pain (radiculopathy, peripheral neuropathy), some patients respond to medications like Neurontin. I’ve seen docs use benzodiazepines in patients with pain just to help put them to sleep.
    Otherwise, it may just be a problem with finding the opioid and dose that work well with your mom. Morphine is usually good if the patients don’t puke – usually because it is so sedating.

  5. Tramadol! Ibuprofen! Tylenol!

    I’ve given thousands of dosages of narcotics, and I’ve never seen an allergic reaction to any of them. I like to, as you said, warn people with morphine that they may “itch” and that’s normal; otherwise, people sometimes freak out and try to say they’re allergic. I’ve been on a personal crusade to remove “N/V” as allergies when I see them on a patient’s e-chart because it’s annoying. “N/V is a side effect of that drug that can be treated, not an allergy, would you still like me to list it as an allergy?” Having 7 drugs that cause nausea listed on the allergy list is just distracting to the physician.

    • From one nurse to another, I am a patient with chronic pain. I have received all chemical interventions for my pain with disastrous results:peeling skin, skin blisters, seratonin syndrome (what fun that was), explosive migraine, itching so severe that bleeding is difficult. As to the opioids, I experience such a massive release of histamine that all sites of injury make me feel I am literally on fire. So have a little more compassion for folks like me who do suffer from true allergies, severe drug reaction, environmental toxins, and food into
      Era cues. Just lay back on a burning log and you will experience just one of my lovely days!

    • My daughter (cancer patient) had true anaphylaxis with Dilaudid….it was horrifying. A week later she had a “bronchial spasm” with Pantamadine – she believes still it was anaphylaxis. I have no idea why in the world you would feel so confident as to remove any allergic notation from anyone’s chart. Geesh!!! Cocky much!

      • I experienced an allergic reaction to Demerol by going into anaphylactic shock within seconds of of being injected. Thanks to the staff and their quick reaction for saving my life.

    • Concerned parent on

      I am very concerned about a nurse or any medical professional who would remove known allergies from a patient record. My son is anaphylactic when given morphine or any if its derivatives. Rare or not, it is very real and very serious. For those who don’t know, anaphylaxis is when the respiratory system shuts down. SHUTS DOWN. I have witnessed my son crashing because if being given morphine and then having seriously labored breathing because of some medical professional probably thinking the same way as you and prescribing hydracodone for pain after hernia surgery. People can die because of some allergies. I implore you to take them seriously, annoying on the chart or not.

      • I was given morphine through iv just before a appendectomy procedure. They told me to count backwards from ten and I had completely lost consciousness as I was trying to say seven. I’m told that I had turned blue, had severe swelling in my face, neck, and hands and finally flatlined, all within 15 seconds from when I started counting down. I haven’t experienced such a reaction with opiates I have had since then but can’t go over 1,000 MG and I can only swing that if I’ve recently ate prior to ingestion. I also can’t have opiate blockers that contains alternatives with similar compounds which has happened frequently. You may consider getting him a medical bracelet to ensure no accidents or careless mistakes occur.

  6. Meperedine doesn’t screw with the sphincter of Oddi, either. But the normeperdine metabolite screws with kidney function, especially in the elderly.

  7. I have an allergy to codeine that I can’t tell if you have mentioned yet – well actually I guess they call it a “reaction”. I hallucinate (sp?). With both of my c-sections, I was given codeine derivatives and both times I had what my dh calls “spidey-senses” kick in. I could here a policeman’s whistle from them directing traffic after a car accident 3 blocks down the road. I also felt a 3.4 earthquake that no one had felt. crazy stuff! And it keeps me awake. Is this considered an allergy? but I don’t seem to have a problem with hydrocodone. Only if it is mixed with something else (which I think they did in the hospital). anyhoo.

  8. Of course, then you get the patients that claim they’re “allergic” to Toradol, Nubain, Stadol, AND Zofran. If someone tells me they’re allergic to Toradol, they might as well just leave.

    • I am confused as to why you would say the pt’s that “claim” they’re allergic to …! I was given Nubain in the ER for a migrain and out of nowhere I begin to have chest tightness, difficulty with breathing, dizzy, and blurred vision and the hospital’s Dr didn’t take it serious and tried to say that I was having anxiety and left me unattended to until someone else threatened to call 911. Then they begin to rush and give me several doses of medicines to counteract a allergic reaction. I kept trying to explain something was wrong…they never told me I had an allergic reation, but from that point on I was afriad to be treated in the ER. I had to be brought in the ER by ambulance for chest pains and they discovered along with whatever was going on with my heart rate that my BP was extremly high and after a while of trying to convince me to take meds, A nurse asked me why was I so afraid and my husband told her of the previous incident and she asked the head Dr if she could search the records to see what happened and she came back and told me exactly what happened and it was in the records that I had indeed had a severe reaction to the Nubain and they had a flag on my records “DO NOT GIVE PT NUBAIN”! She even told me all the measures that they did to back track their steps. It was also in my records from previous visits that Pt isn’t a medicine seeker, is only desiring to stop the voimiting and is willing to tolerate the pain. So I am confused when you say this…are there not supose to be a “REAL” possiblity that one can actually be allergic to these medications. Not being argumentive just trying to understand.

  9. This is an older post so not sure who will see this, but I was told by an ED nurse that Morphine and Dilaudid were causing me to vomit.

    I presented to ED with kidney stones. The two WORST times in my life were being in the ED vomiting..incessantly along with kidney stone pain.

    So for 3 years… my mantra (to anyone who came near me in the hospital) was do not give me those drugs because of getting so sick with them.

    This past summer, back in ED and became a hospital admit (not for kidney stones) and my doc decided to try morphine and I did not get sick.

    So…it was the stuck kidney stones!

    But…I am guessing…maybe 18 hours later… I woke up scratching violently…everywhere. Could not stop! Not a pretty site and embarrassing.

    I actually thought I picked something up from the OR that night.

    It was the Morphine! It went away once it was out of my system. Dilauded gives me a headache as soon as it goes in but can counter it with Toradol.

    Demerol doesn’t give me any side effects, but they don’t use it for some reason… something about elderly population. ?? (If I understood correctly)

  10. Would a psuedoallergy be localized at the injection site only? If rash presents on face or other arm, would this be considered a true allergic reaction? Pt with hx of morphine allergy given dilaudid and facial rash and hives on both arms occurred. Facial rash persists with oxycodone use following ER visit for nephrolithiasis. Thoughts? Thank you in advance!

  11. I have an allergic reaction when I have taken hydromorphone. I can hardly breath when I have done so. My chest becomes so congested and tight for over 24 hrs I don’t think I ever want to try this opioid again. My question is: is it safe to try other opiates such as oxymorphone that are similar to hydromorphone because I am fine on oxycodone, hydrocodone and OxyContin? The problem has only occurred with hydromorphone and ms contin..
    Please can someone tell me what options I have because I really don’t want to have breathing problems when taking medication for pain.. Danger!
    Thanks Squeal

  12. I have an aspirin allergy and had a reaction to Toradol after my c section. I do not test my luck but my symptoms have been swelling in face and neck and difficulty breathing. I feel that is a “true” allergic reaction. I have only taken Advil(as a teen) and Toradol (after cs) when I got those symptoms. I have had a “sensitivity” to hydrocodone once. Pretty much just itchy but worried me with my history of allergies so I add it to list of allergies with an explanation that it wasn’t that bad. Worst part was I took it before bed and was worried it would turn into an actual reaction. I can handle itching but have struggled my whole life to find something with anti inflammatory properties without the swelling.

  13. I have had a severe histamine mediated allergic reaction to Toradol; for any medical students or residents out there who don’t understand what this means, it means that giving me toradol can easilly kill me! I have hronic back ain (documented) and I generally refuse any medical teratment for pain, but after a recent car crash I ended up in the ER where a moralistic, immature resident told me that “nobody is allergic to toradol, you must be drug-seeking”..I refused to sign a consent for any treatment and pushed this idiot resident out of my way. The head of ortho met as I was dressing in the ER and told me that she was sorry for the way that I was treated’ she offered me narcotics and a nurse tried to give me demoral which I refused. My x-rays became available and showed ignificant damage; the ortho doc (not a resident, a real physician) told me that I had spinal damage that required admission. I asked the ortho doc if she would consent to admission after being treated th was I was; she hung her head without answering. I finally left the ER, basically crawling to my car.

  14. Connie Skinner on

    My reactions to morphine, codeine and demerol include immediate extremely lowered blood pressure, difficulty breathing, slowed heartbeat, confusion, dizziness. Desert Springs hospital in Las Vegas gave me morphine twice following a head injury, despite my telling them I was allergic to these narcotics. All my vital signs bottomed out and only the invention of my RN daughter saved my life. I am also very sensitive to wine, liquor, etc. and antihistimines do not work on me, but hype me up. At what point do doctors and nurses become gods and decide that what I know to be true, is not?

  15. Connie:

    I agree completely. I have had severe anaphylactic reactions to both morphine and codeine. I have a very long list of tested food allergies also including soy, yet a number of doctors and anesthesiologists have scoffed at my “so called allergies”, demeaned me by insuinuating I’m both stupid and a hypochondriac, etc.

    I have to have surgery soon for diverticulitis and it’s been a complicated process to figure out how to anesthetize me without the use of propofol (contains a high concentration of soy oil) and opiates/opiods, as well as how to manage post operative pain.

    It’s insulting to have a medical professional not take a situation that to you could be life-threatening, seriously. Worse, knowing that in a surgical setting, a doctor may “override” your allergies (and I’m not talking about some redness and itching here, I’m talking past demonstrated full anaphylaxis requiring emergency room visits) and choose to inject you with something that will likely kill you.

    Another issue is that my allergist is perfectly willing to test me properly for alternative synthetic opioids like fentanyl or demerol, but it’s nearly impossible to GET these substances outside a hospital even with a prescription, so testing (to be 100% sure) is often difficult.

  16. You say you can’t be “allergic” to narcotics … bull … you give me ANY narcotics and first i start to itch and then my throat just closes right up… I have had EVERY drug out there for different surgeries over the years (i have had 12 surgeries because of PCOS/endometrosis, csect, gall bladder and Hysterectomy) If i hear those words well we have to give you something for the pain … last time i heard those words I went into anaphylactic shock and they had to give me so much stuff to counteract the ONE shot of demerol that i don’t remember the 3 days I was in the hospital i was so out of it… NOT a good thing … I can take Tylenol and Ibuprophen and that is IT!! I went to an allergist and he told me it was all in my head that is was not a real allergy.. I think i am going to find a new allergist 🙂 I am also allergic to scents and latex. I can’t even go to the dentist and get work done because I am allergic to the lidocaine, carbocaine and novocaine!! It royally sucks.. so please don’t tell me you can’t be allergic to these drugs .. i am proof that you can.. I have had major reactions to ALL of them .. they have tried them all and i have the same reaction to them all!!

  17. I am one of those persons who while not “allergic” to narcotics, nonetheless should never be given them. If I do not immediately begin vomiting, I experience delirium and suicidal depression with hallucinations. It is not fun in the slightest. Last May while in the recovery room post-op for a partial vulvectomy, I apparently grunted and the attending nurse pumped 3 types of narcotic pain meds into the IV. 4 days later, I was still feeling the effects and ended up sitting on the bed with my 9 mm, deciding which spot would be better – chest or headshot.

    When a patient says they are ‘allergic’ to a narcotic, while it is probably not a true allergy reaction, there can well be a very good reason indeed, they ought not be given opioids as analgesics. I am one of them.

    Also, Toradol creates a really distressing and painful abdominal/intestinal reaction for me – swelling of the abdomen, inability to evacuate the bowels for several days, bad stomach cramps. Much worse than the initial pain it was given for. Sometimes the ‘cure’ is worse than the ailment.

  18. I told my Dr+nurses I was allergic to morphine before my emergency appendectomy. They didn’t take me seriously,gave it to me anyway+were somehow surprised when I stopped breathing+had to be intubated(sp?). I nearly died+could have(probably should have) sued. Please don’t make light of it just because you don’t see it often,it may be rare,but morphine allergies certainly exist.

    • I live in a non-English-speaking country and had to go to the ER here with a shattered kneecap. I took a sharpie and wrote NO OPIATES over the veins on both my inner arms before calling the ambulance. Good thing. I’m thinking of getting it tattooed.

  19. fentynal caused me to turn blue and they had to bag me!!!! WHAT DO I PUT DOWN ?????? i almost died?????AM I allergic or did doc give too much???.I am sooooooo scared to have operation.

  20. I have severe GI symptoms (specifically, non stop vomiting and dry heaving when I take any of the drugs that you have listed in the morphine group. I also experience severe anxiety and restlessness when given phenergan or compazine (sp?). I do fine with Benadryl though. I was diagnosed with SLE and Fibromyalgia 13 years ago and live in horrible, constant pain due to my fear of taking narcotics. I take ibuprofen like candy (horrible I know) but it at least has allowed me to function up until now. No other meds have worked. Today my doctor prescribed me Fentanyl 25mcg patches…1 every 72hrs. They are unopened and locked in my safe as I’m scared to death of trying them for fear of developing an addiction or having a GI response. If you have any suggestions at all I would be forever grateful. I refuse to allow my illness to overtake my life, but I’m to the point where the pain is now beginning to claim a great part of it. Please help!

    • Do not take fentynal!!not alone in your home. make an appointment to be observed and let doctors care for you.GOD BLESS!!!

  21. okay , I don’t really know if im allergic to perocets but I think so. I had surgery and was giving percoets before the procedure . The percocets caused me to itch . When I say itch I mean itch. The percocets caused me to itch sooooooooooooooo bad . I was itching so bad that I was scratching so hard I had welps on me . I couldn’t feel anything . I even had some scratches where blood was coming out of my scars . I litteraly couldn’t feel anything when I was scratching . the doctors were like ‘ oh my gosh look at your back ! as in shock . my whole body was itching and it was really uncontrollable . later on I took some benedrill and it calmed it down . am I allegic to percocets ?

  22. Hello ! I’m 48 yes old . I don’t really know what meds I’m allergic too, but I know every time they put me to sleep for any kind of surgery I go into cardiac arrest! The last time I had surgery was on my breast! I told the Dr. About my bad experiences with being put to sleep. So he said he wouldn’t give me any thing that would knock me all the way out . So he said he gave a shot of demerohl and a shot of Pherahan to keep me from being sick at my stomach . so I was in and out . when he was done with the surgery I was getting ready to go home and my mom was driving me as we were leaving the hospital I felt like something was coming right up my chest tiring my air off . I couldn’t breath . next thing I knew There were Dr.s shoving shots in both my arms saying I was allergic to the meds that he gave me for surgery. Well I done that about 3 times . come a hair of dying . So I don’t know what to do but I’m scared to dealth of Dr.s and scared to take any meds. What should I do? Thanks Annette….

    • get all this in writing!!!!get a medical bracelet!!! A.S.A.P!! I understand I am going through same thing. PS. also get a health care proxy!

  23. I was given a combo of Demerol and unknown (not remembered) anesthesia, and I seized up/had muscle issues. This sounds like more of a bad reaction than a true allergy, but I also feel like I should avoid taking Demerol if that’s the offending drug (and then cross my fingers that I never get the other one). Thoughts?

  24. As a Nurse, I’ve seen many charts with “allergies” listed for miles and miles. As a Nurse, you are taught the difference between anaphylactic shock and undesirable side effects. One way or another, if a patient says they are allergic to a medication it is our job to find out what happens when the patient takes the medicine. It’s also NOT our job to try and erase “N/V” (nausea and vomiting) as a type of allergy or undesirable side effect. N/V can cause severe dehydration, and QUICK. We have to consider and weigh options. Also, a patient can develop an allergy to a medication that he/she had previously taken, and may not be aware it’s the medicine (because it’s been taken in the past).

    Having been a patient myself, I discovered I was experiencing undesirable side effects to an opioid derivative a little too late. It nearly cost me my life, and included an emergency surgery organ removal, and a toxic liver. I thought my severe pain was making me sick, or I had a viral stomach bug. If you find a good Doctor, he/she won’t want to prescribe a pain medication that makes you so sick. Unfortunately, it does not leave many options.

    So, to the Nurses and Doctors that see a million “allergies” listed and feel It’s your job to over step your boundaries and administer the medication anyway , shame on you. If the patient states they are willing to overlook itching, nausea, vomiting and diarrhea due to a medical emergency (if they are able to state it) then and only then should it be considered.

    • I can’t breathe if I take lortab, percocet, tylox or tramadol. When I asked at the ER what medication I could take in their place, I was not told anything, the nurse gave me a demerol shot and sent me on my way. Since I am a paraplegic that lives alone, I don’t take unnecessary risks, I just say I’m allergic to opiates and so far, no one has given me flack about it.

  25. It’s interesting reading all the comments. My doctor advised me to report my reaction to codeine as an allergy even though I don’t suppose technically it was. I experienced a loss of a day of time and memory, and have it reported I acted as if I was extremely drunk. A dentist a few years later prescribed Percocet, and my experience on that was an afternoon of extraordinary hallucinations of huge cartoon bugs and the feeling that my head was floating two feet above my body. Thankfully I thought the bugs were hilarious rather than scary. I chose to not take any more pills after that one. Both sound fairly benign, but when I told a surgeon later he was rather alarmed that I’d been prescribed the percocet after reporting the initial allergy, and he was adamant that I take care to avoid both in the future. He said something to the effect that even though my reactions were fairly benign, there was no telling what further exposure would do, and could be very dangerous. Thankfully, I’ve had no reactions to the alternatives, but I’ve never been lead to feel that describing my reactions was taken anything but seriously by any medical professional, except perhaps that one dentist who also prescribed codeine despite my chart.

  26. I work in an ER, I am also a writer and researcher, and am a patient who happens to (most likely) have an abnormality with the CYP450 genetic system. I am surprised and shocked by all the doctors and nurses here who are dismissing patient complaints. An abnormality in the way metabolism works will in fact cause a patient to be “allergic” to even such mundane drugs as Benadryl and ibuprofen. Those “drug seekers” and patients that you don’t want to believe may in fact be telling you the truth. Some people metabolize opioids at 4 times the rate that is normal. These people are living in constant and unnecessary pain unless they have an educated doctor who understands the signs of an ultra rapid CYP450 metabolizer. These particular patients can and should be prescribed doses that are accurate for their metabolism rate.

    On the flip side, some people should be prescribed 1/4 of a regular dose. Most of the “overdoses” are accidental due to slow metabolizers who have developed a toxic build up in their system.

    It’s not as simple as this. There are many genes and many drug/drug interactions responses. Someone with this abnormality is taking a chance with every medication they take because it can be poison to their system, or it can have no effect at all depending on what medication it is or what their metabolism is. So before you label someone as noncompliant, think about that.

    My story: I am allergic to Benadryl. I first discovered this when I was 9 and my grandmother gave me some when I had chicken pox. It had the opposite effect of what it is supposed to. It literally had me climbing the walls, had me feeling like I had bugs crawling all over me. I was hyper, wired, and running around so crazy, itching even worse than before. It was the most bizarre thing. This has happened every time I have taken anything with an antihistamine in it.

    Alcohol has never really had an effect on me. When my friends were stumbling and slurring their words, I was wondering what the big deal was. Alcoholism will never be a problem for me, because I don’t get any feeling from it. I suppose I metabolize it so fast, before it has a chance to give me a drunk feeling.

    I went in for oral surgery (first time I’ve ever had any anesthesia or anything, never had any pain meds) and was told it took them “4 times the normal amount to get me under” and then “I started waking up halfway through and they had to give me more to keep me under.” I happened to know the dental assistant from church, and she said it was the strangest thing she’d ever seen, and normally someone with that high of a tolerance has built it up through many years of drug abuse, and she knew that wasn’t the case with me. Plus, with that many years of drug abuse that it would have taken to get a tolerance like that, the evidence would show on my body, and I obviously didn’t look like someone who had been abusing drugs for years at a hard rate. I was just metabolizing them that fast.

    Crazily enough, I have never been able to handle any opioid pain medication. At all. The slightest amount gives me the worst reaction ever. Severe pain in my stomach like I’ve been punched in the gut. Such bad pain that I can’t draw a breath and I curl up into a ball and cry. My muscles all over tense up in pain and I cry because it hurts so bad. This lasts for about 30-45 minutes and then goes away. Would you call this an allergic reaction? I don’t know. Not that I’ve tried many narcotics, because (yep, you guessed it) when doctors hear “I’m allergic to Lortab” they usually aren’t very open to trying other meds. I can’t take Ultram, and I’ve had Dilaudid and it did the same thing as well. Taking the medication with Phenergan doesn’t really seem to help that symptom. The pain from the pain meds (ironically) is so severe that I’m not willing to keep experimenting. I’d rather live with my chronic pain than suffer from that.

    I have tried an SSRI 4 times in my life, and absolutely refuse to do so again. Once again, doctors seem to be under the impression that these are “safe” and keep urging me to ‘try again” and seem to not listen when I tell them I have adverse reactions. Serotonin syndrome is no fun. With one pill it was bad, with two pills…lets just say I now have a glimpse into what it might be like to be schizophrenic and manic, and this has given me a new appreciation for my patients. If they live like that every day, I will never take my healthy mind for granted again. Imagine what could have happened if I had taken more pills and given it the recommended two weeks adjustment period. I could’ve died. That is a side effect, you know.

    If you have a toxic build up due to not metabolizing properly, medications don’t work right and can be poison.

    The genetic testing for this is expensive and is not covered by most insurances. If I could afford it, I would get it, but there are questionnaires that some pain management doctors are beginning to use when they suspect a CYP450 abnormality in their patients that can help them more adequately treat them. Pain management and psychiatric doctors are really the only ones (to my knowledge) that are using this “personalized” treatment approach in treating patients, partly because they are the “last stop” in a lot of cases for patients after all other doctors have given up, and partly because it is opioid pain meds and psychiatric meds that patients most often have trouble with. However, these aren’t the only types of meds that are affected by CYP450 abnormalities. Warfarin and some AIDS medications are, to name a few. So I certainly hope sharing my story helps others get the treatment they need. I certainly know what it feels like to have a doctor not believe me when I tell them the reactions I have to certain medications, and I know good and well I’m telling the truth.
