Which drugs can help my shellfish allergy?

Epinephrine: For severe shellfish allergy, only injectable Epinephrine for reactions is a reliable treatment. Some people with very mild allergies can use antihistamines alone, but everyone should have Epinephrine available. Unfortunately, there are no drugs that will prevent or resolve a food allergy so you can eat the food without risk, although this is an active area of research.

None: There are no medications to prevent reacting to foods; you simply have to avoid eating the foods to which you're allergic. Even if you've had a mild reaction to a food in the past, it is best not to "roll the dice" - you might have a more severe reaction in the future. Depending on the severity, antihistamines, bronchodilators and/or Epinephrine may be needed if you have an allergic reaction.
