Were you looking for information about Tessalon? Tessalon Perls is a common misspelling of Tessalon Perles.
Healthcare providers may prescribe a cough suppressant known as Tessalon® (benzonatate) to stop coughing in adults and children as young as 10 years old. The medication comes in different forms and strengths, including Tessalon Perles (the 100-mg strength of brand-name Tessalon). The Perles get their name due to the fact that the liquid-filled gel capsules have a spherical shape. They are generally well tolerated, but side effects like nausea, constipation, or a "chilly" sensation have been reported.
