I have literally just found out that I'm allergic to darvocet and Am curious as to weather or not there is any one else out the that is allergic too. My reaction to it was that my stomach swelled up to the point where I looked like a 4 1/2 month pregant lady. Needless to say I am not pregnant. I also had a very hard time breathing. It was so close to feeling like an anxiety attack that I took my Ativan to ease the symptoms of my breathing and the feeling that there were bricks on my chest, away. However the Ativan did not help what so ever. It has been a very frightening experience. I have a surgery coming up and am worried that I won't be able to take anything for the pain afterward. My question to anyone is if I'm allergic to darvocet does that mean I'm allergic to other main meds as well? My pain has been unbearable and the doctor I see has prescribed me Tylenol 3. I'm worried to take it for fear that I'm going to have another reaction similarr to the darvocet. I have taken Vikodin and percoset in the past for a tubal that I had 3 years ago and didn't have nearly the problems I've had with the darvocet. Just shortness of breath which was okay because I had been in the hospital when it was administered and they gave me the Ativan for that at the time to calm it down. Does anyone know if that means I'm allergic to all pain meds?
