Hi, welcome to the forum, you
have a history of drug allergy.
It is quite rare one having allergy to all the medication.
In such cases you need to keep anti histaminics with you so as to prevent allergic reactions. Drugs like penicillin and sulfa group of drugs are most common cause for hypersensitivity reaction. As you have a history of penicillin allergy. If your body is hypersensitive to sulfa, reaction will be similar to that you develop for penicillin.
