Tessalon® (benzonatate) is a cough suppressant that is available by prescription only. Unlike many cough medications, it doesn't come in the form of a syrup -- it comes in the form of gel capsules. Each Tessalon capsule is filled with liquid and comes in either a spherical or oblong shape, depending on the strength and/or the manufacturer.
Tessalon comes in two strengths (100 or 200 mg) and is taken by mouth, up to three times a day. It is thought to work as an anesthetic, essentially numbing certain receptors in the lungs and respiratory passages.
Be sure to swallow this medication whole. It is important that the capsules are never chewed or sucked, as serious reactions could occur if Tessalon is taken this way. If you are unable to swallow capsules, talk to your healthcare provider about other options for treating your cough. Also, make sure your healthcare provider is aware if you have any allergies or are taking any other medications.
