What is the strongest allergy medication?

More Details: There are lots of different allergy medications out there so I will need more information to provide further guidance. Are you referring to antihistamines, nasal steroid sprays, allergy shots? There is no "best" or "strongest" allergy medications because each patient is so different. Different medications or combinations of medications might be required to get you feeling better. See an Allergist.

What is going on?: If you are having severe allergic reaction (food, bees, medication), call 911 now. Take your epinephrine as prescribed for allergic shock (anaphylaxis). For non-urgent matters, diphenhydramine is plenty strong for most mild allergies (and can cause drowsiness - don't drive). Many less strong antihistamines are over the counter. If not work - time to make an appointment with the provider.
