Antihistamine Tablets

Antihistamine tablets are used many times instead of liquid, pills and capsules, each of which has benefits and drawbacks. Some liquids might taste terrible. Sometimes, the medicinal compound won't compress into pill form. Or people have hard times swallowing pills and prefer tablets.

Antihistamine Tablet Doses and Forms

Tablets come in various doses and forms. The most popular form of antihistamine tablets are in compressed form. That's because controlled dosages are possible. Popular antihistamine tablets can be found in 25 mg doses, which can be taken whole or divided into sections.

While antihistamines can be administered as ointments, eye drop, or nasal sprays, the most popular method for taking antihistamine tablets is orally, swallowing them.

Antihistamine Suppositories General Dosage and Method

Antihistamine Tablets can be a few millimeters long up to maybe a centimeter. They can be made into any color or form, which is done frequently to distinguish medications from each other. Different manufacturers also use stamp codes and symbols for tracking purposes.

When to take antihistamine tablets depends on symptoms and which type of antihistamine. Earlier classes of antihistamines produce drowsiness, and two classes of antihistamines developed since then have reduced those side effects.

Antihistamine tablets combat the allergy-producing histamines. Allergens release large amounts of histamines -- distributed on the cellular level -- that cause inflammatory responses such as runny noses, swollen eyes, nausea and sleep disorders, and even stomach ulcers.

Antihistamines were first used successfully to treat people in 1942. About 50 million Americans suffer allergies, costing $18 billion a year, researchers say.
