Sulpher allergies ?

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the treatment for sulfa drug allergies.
The treatment goal is to relieve symptoms and prevent a severe reaction.
Treatment may include:
1. Antihistamines to relieve mild symptoms such as rash, hives, and itching.
2. Bronchodilators such as albuterol to reduce asthma-like symptoms (moderate wheezing or cough)
3. Corticosteroids applied to the skin, given by mouth, or given intravenously (directly into a vein)
4. Epinephrine by injection to treat anaphylaxis
The offending medication and similar drugs should be avoided. Make sure all your health care providers -- including dentists and hospital personnel -- know about any drug allergies that you or your children have.
Identifying jewellery or cards (such as Medic-Alert or others) may be recommended.
Occasionally, drug allergy responds to desensitization, where increasing doses of a medicine are given to improve a person's tolerance of the drug. This should only be done by an allergist.
Hope this addresses your query. Take care.
