Is anyone else allergic to Dextromethorphan?

I am not really allergic, but more oversensitive. This is a recent thing too. My sophomore year of high school I had a nasty cough, and being in theatre, I needed to shut it up while back stage during performances. I took 60 mg of DM cough medicine and thought nothing of it (i had taken it for years), but half way into our show I blacked out (talk about some serious improv for the other actors lol). I don't remember a thing but I woke up at the hospital and the doctor said I was oversensitive to the main drug in cough suppressants. 

I thought I was the only one too, until I did some research (now) as a freshman in college battling her first cold. 

I've been allergic to it since I was a kid when they first started putting it in cough medicine in the 60's. Makes for a tough cold season. Took a while to figure out the link between getting the severe hives and the cough medicine. Fortunately I don't get the internal kind where your throat swells up, but I sure looked terrible on the outside and can't stand the itching all over. Benadryl helps reduce the reaction. My early cases were so bad my childhood doctor said he was going to write me up in the New England Journal of Medicine.

Same here......Feel numb and weird....Dizzy. The first time this happend I threw up....now I am going on the second time and just feel really numb....like if i was stoned .....but in a bed way

Yes I use to take Delsym and thought it worked well. However, I took it from an open bottle while sick and got stomach pain, dizzy, diahrea and the shakes. I felt like I was poisened. Once it passed thru me I felt much better. Since I had taken it many times before I tried it again this time from a new bottle. Same reaction. Next time I'm sick I don't know what I can take. Any ideas?

I have a similar reaction though not all over my entire body.I get a huge hive on my thigh that itches at first then grows more and more painful. It feels like a sunburn and eventually peels like one. With each exposure to the DM the hive is bigger but always comes out in the same spot.

Im taking Azilect so I've been told by my doctor not to take any medication with DXM. The problem I have is when I do get a cold I contact my movement disorder doctor which refers me to my primary care doctor. My primary care wants to send me to movement disorder dr which I can understand Parkinson is a disease. It seems to me that even the doctors don't know what meds to prescribe with Azilect. This morning called my movement disorder dr I have a sore throat, head cold with coughing with mucous I asked for something over the counter or a prescription again my doctor referred me to my primary then tells me I should see a nose throat ear dr. I do not know what cough cold medicine I can take with Azilect.

I am too! My lips and eye swelled and it took so long to go away.

I took Buckley's this morning and I am not sure what caused my reaction in it but probably not the DM because I took two pills (Benylin)last night that had DM in them

 I reacted within minutes after the Buckley's and with no one home  I phoned 911

 I broke out and severe hives but my throat and tongue were okay and by the time the ambulance arrived at my home I had passed out...  spent seven hours at the hospital and they released me without really knowing what happened

I am allergic to opiates, and dextromethorphan is an opiate, so I've never been able to use any of the OTC cough & cold remedies. There is one non- opiate cough suppressant, by prescription only, called benzonatate.

I thought I was the only odd one. I took 2 tsp and ended up in emergency room covered with hives and they were in my lungs. Shot up with steroid and Benadryl.

I am as well. My eye swells as well as my lips. I'm trying to find an alternative but I'm not having any luck.

Hi, I'm also allergic to this. What a relief to know that I am not the only one. I also have bronchitis, which sucks. Doctor gave me an inhaler and prescribed Tussinex. Hope that helps.

Uh oh, I took a generic version of NyQuil and instantly broke out in hives. And I couldn't breathe so I got to my inhaler. I think I'm going to the doctor today.

Dextromethorphan caused my throat to begin swelling shut rather quickly. I popped two Benadryl and went back to bed (hospital doesn't do too much different).
All I can take is night time cold meds, like nighttime TheraFlu, with diphenhydramine (Benadryl) in it. Other options during day time would be a decongestant and/or expectorant (Mucinex) and an antihistamine that won't make you as drowsy as Benadryl.

Similar reaction after taking one day's dose. Broke out with hive under chin and one on upper back about the size of silver dollar.
Happened once before, same spots. Itches like hell and then peels like a sunburn. No more DM products for me.
