I have developed an awful allergy to cod liver oil which keeps repeating even though i've stopped taking the capsules . can you advise what i can do?

Cod liver oil: Allergic reactions to medications, supplements or foods usually resolve within 1-3 days, unless metabolites are still in the system and haven't cleared. If allergy symptoms are severe and include difficulty breathing or swallowing, etc, see a healthcare provider. If symptoms are mild, an antihistamine should be helpful. Cod liver oil would be an unusual allergy, so if persists see allergist.
