Over the counter drugs for allergies

  • Antihistamines: The drugs most commonly used to relieve the symptoms of allergies and used as allergy treatment are antihistamines. Some antihistamines are available without a prescription, and some require a prescription. Antihistamines block the effects of histamine rather than stop its production. Taking antihistamines partially relieves the itching and reduces the swelling due to hives or mild angioedema.
