What is drug hypersensitivity?
336024
highly sensitive to drugs (your body reacts very strongly - usually negatively to drugs). \n\nhaving a slow metabolism can be a cause of this because the drug does not get processed quick enough to have its effect and it stays in your blood system. If you take your next dosage the effects are compounded.

NO, mixing Singular (a luekotriene blocker) with Claritin (an H1 histamine blocker) will not cause an allergic reaction, and many many people take both drugs without any problems. And generic drugs are the basically the same as name-brand, so that isn't the problem. She may be allergic to something in the Claritin, or it could have been an allergic reaction to something else.. Most likely food or another medication considering the symptoms. Obviously she already has allergies or mast cell problems since she is taking Singular and an antihistamine to begin with....

tachyphylaxis is development of immunity to a drug. After repeated use of topical steroids, the capillaries in the skin do not constrict as well, requiring higher doses or more frequent application of the steroid. With high-potency steroids this effect has been documented after 4 days of applying a topical steroid three times a day. The ability of the blood vessels to constrict returns 4 days after stopping therapy.

Normally you shouldn't stop taking bactrim/septra because it's an anitbiotic. You don't want your body to build up a resistance to the medication. I would call the doctors office anyways, many doctors have an answering service that picks up phone calls during off hours. Tell them that you believe you might be having an allergic reaction to the medication, and ask that the doctor give you call back. You doctor will then be able to discuss with you, any other opitions you might have. Good Luck!

Fluoxetine / Prozac can lead to allergic reactions. The chances are very low and comparable to other psychotropic drugs. Every drug can lead to allergic reactions. In this case it seems that allergy is being caused by exposure to cold. Stay on prozac and discuss it with your practitioner. Do not discontinue it without consultation.
