Clemastine is an over-the-counter antihistamine sold in the United States under the name Tavist. While not nonsedating like loratadine or fexofenadine, it seems to have fewer side effects than most widely used "regular" antihistamines.

An allergy is a immune malfunction whereby a person's body is hypersensitised to react immunologically to typically nonimmunogenic substances. When a person is hypersensitised these substances are known as allergens. The word allergy derives from the Greek words allos meaning "other" and ergon meaning "reaction" or "reactivity". Reactions can vary from the benign runny nose, to life-threatening anaphylactic shock and death.
