Prescription antihistamine

If you are suffering from hay fever or allergic-type symptoms such as an itchy nose, itchy rash or bite on the skin, or redness and minor swelling of the skin, then an antihistamine may help relieve these symptoms.

Minor allergic reactions to products (washing detergent, creams, perfume), and food or plant reactions (stinging nettles) can be safely treated with over-the-counter antihistamines and should get better in hours to days. Make sure to avoid whatever causes the reaction in the future.

If you find that you are getting regular allergic reactions and do not know the reason why, you should discuss it with your doctor, and you may benefit from getting allergy testing.
