Antihistamine medication.

Got an Allergy?

Can you feel a bit of hay fever or rhinitis coming on? Prone to travel sickness or some pollen in the air?

An antihistamine will often be your relief.

Antihistamines are used to treat allergies, motion sickness, certain types of headaches, certain diseases (such as Crohn's disease and acute multiple sclerosis), some stomach secretory conditions, and so on. Antihistamines are generally well absorbed from the gut, metabolized primarily in the liver and most have a duration of action of about 4-6 hours. They are the drug of choice for treatment of colds and allergies but they do not cure a cold or allergy but rather provide relief from symptoms.

The term antihistamine refers to a drug which blocks H1 (histamine, type 1) receptors in the body. (Drugs that are H2-receptor antagonists are those used to treat gastric ulcers as they block gastric-acid and enzyme secretion.) Antihistamines compete for the H1 receptors on blood-vessel endothelial cells and smooth muscle cells. As competitive inhibitors, the antihistamines bind to the receptors because there is more of the antihistamine than the natural histamine.

Some antihistamine medicines need a prescription , while others are available over the counter. Here are our products available online.
