The medications you were prescribed, fexofenadine (an antihistamine) and methylprednisolone (a steroid), are excellent for quickly relieving your current allergic symptoms. However, they only treat the active reaction and do not permanently cure the underlying food allergy. Currently, there is no permanent cure for food allergies. The most reliable long-term solution is identifying the specific trigger food and avoiding it. I highly recommend seeing an allergist for allergy testing to pinpoint the exact cause. Rest assured, food allergies are highly manageable, and knowing your triggers is the key to staying safe and symptom-free.
