Antihistamines

Antihistamines

Reduce or block histamines, so they stop allergy symptoms. These medicines work well to relieve symptoms of different types of allergies, including seasonal (hay fever), indoor, and food allergies. However, they can’t relieve every symptom. To treat nasal congestion, your doctor may recommend a decongestant. Examples of this include Diphenhydramine (Benadryl), and Loratadine (Claritin).
