How to use Tessalon Perles
Take this medication by mouth with or without food, usually 3 times daily as needed or as directed by your doctor.
Swallow this medication whole. Do not chew, suck, or dissolve this medication in your mouth. Doing so will cause a loss of feeling in your mouth/throat and may cause choking or a severe allergic reaction. (See also Side Effects section.) Do not eat or drink until the numbness goes away. Get medical help right away if the numbness persists or worsens.
Dosage is based on your medical condition and response to therapy. Do not take more than 200 milligrams at one time. Taking more benzonatate than prescribed will not make your cough go away faster but may result in serious side effects.
Tell your doctor if your condition persists or worsens.
