Tavist is a medication that is used for treating symptoms of respiratory allergies or the common cold. It can be used to relieve sneezing, a runny nose, and various other symptoms. Occasionally, healthcare providers may also recommend off-label uses of Tavist, such as for the treatment of morning sickness and allergic skin reactions. This non-prescription medication is approved for use in adults and children as young as 12 years old.
Tavist® Allergy (clemastine fumarate) is an over-the counter medication used to treat allergy and common cold symptoms. Specifically, Tavist is approved to treat the following symptoms:
- Runny nose
- Itchy, watery eyes
- Itching of the nose or throat.
Notice that Tavist is not approved to treat nasal congestion. A nasal decongestant (such as Sudafed® or Sudafed PE®) is usually necessary to treat congestion.
Tavist belongs to a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body (known as H1 receptors). Since allergic reactions are partly caused by the release of histamine from certain cells in the body, Tavist can help relieve or prevent allergy symptoms.
Tavist also blocks acetylcholine receptors, an action which produces some of the unpleasant side effects of the medication (such as dry mouth or difficulty urinating) but also helps to relieve a runny nose.
Tavist is approved for use in children as young as 12 years old. It should not be used in younger children.
