Originally approved by the FDA in 1977, clemastine is a first-generation antihistamine used to treat allergy symptoms. The most common trade names for clemastine are Tavist and Dayhist, though over-the-counter versions in the U.S. have been discontinued, making it a prescription-only medication.

In November 2000, the U.S. Food and Drug Administration (FDA) issued a public warning that led to the voluntary recall of dozens of over-the-counter (OTC) medications, including the combination product Tavist-D. This action, which answers the question, 'Why was Tavist taken off the market?', was based on growing evidence that one of its active ingredients, phenylpropanolamine (PPA), could increase the risk of hemorrhagic stroke.

While it was once a popular over-the-counter (OTC) allergy medicine, the OTC version of clemastine was discontinued in the U.S. years ago. So, is clemastine available in the US? Yes, but only as a prescription medication for both adults and children. This change means patients must consult a healthcare provider to obtain the drug.

First-generation antihistamines like clemastine and Benadryl (diphenhydramine) have been used for decades to relieve allergy symptoms, but they are not identical medications. Understanding the core differences and similarities is vital for choosing the right one for your specific needs.

Clemastine is a first-generation antihistamine that has been used since its approval in the United States in 1977 for the relief of symptoms associated with allergic rhinitis, the common cold, and urticaria. It is available in various generic formulations and, in the past, was sold under brand names like Tavist® Allergy and Dayhist® Allergy.
