Antihistamine Tablets

Antihistamines treat allergy symptoms. Immune system cells known as "mast cells" release a substance called histamine, which attaches to receptors in blood vessels causing them to enlarge. Histamine also binds to other receptors causing redness, swelling, itching and changes in secretions. By blocking histamine receptors, antihistamines prevent these symptoms.

Antihistamines can be taken as tablets, capsules, liquid, nasal spray or eye drops. Antihistamine eye drops can relieve red itchy eyes, while nasal sprays can be used to treat the symptoms of seasonal or year-round allergies.
