Symptomatic relief of cough associated with respiratory infections such as the common cold, bronchitis, pneumonia, and other conditions that cause persistent coughing. It is not used to treat the underlying infection itself.
Tessalon Perles contains benzonatate, a peripherally acting antitussive that works by numbing the stretch receptors in the lungs and airways. This reduces the cough reflex that triggers persistent coughing.
Capsules must be swallowed whole and never chewed, crushed, or dissolved in the mouth, as this can cause numbing of the mouth and potentially lead to choking or severe side effects. Common side effects may include drowsiness, dizziness, or headache. Patients should consult their healthcare provider before use, especially if pregnant, breastfeeding, or taking other medications.
