Tessalon Perles (generic name: benzonatate) are a widely used prescription medication for the relief of coughs caused by respiratory tract infections such as colds, bronchitis, and pneumonia. As a non-narcotic antitussive, Tessalon Perles provide an effective alternative to opioid-based cough suppressants, offering relief without the risk of dependency. In this comprehensive guide, we explore every aspect of this medication, from its medical uses and mechanism of action to proper dosage, side effects, and important precautions.
What Are Tessalon Perles?
Tessalon Perles are soft gel capsules that contain the active ingredient benzonatate, a synthetic compound chemically related to local anesthetics. They are typically prescribed to treat coughing that is persistent and non-productive—coughs that do not produce mucus. Approved by the FDA, Tessalon Perles have been in use since the 1950s, making them a time-tested solution for patients suffering from painful, irritating coughs.
How Tessalon Perles Work
Benzonatate works by numbing the stretch receptors in the lungs and airways. These receptors send signals to the brain that trigger coughing. By desensitizing these receptors, Tessalon Perles effectively reduce the cough reflex without suppressing breathing, which makes them safer for certain populations compared to codeine-based cough suppressants.
Common Uses of Tessalon Perles
Tessalon Perles are prescribed in a variety of scenarios involving dry, persistent cough. Common conditions that may require benzonatate include:
Acute bronchitis
Pneumonia
Chronic obstructive pulmonary disease (COPD)
Asthma-related cough
Upper respiratory tract infections
Post-operative coughing
Cough caused by lung cancer or other pulmonary conditions
The key benefit is symptom relief—by reducing the urge to cough, patients experience less throat irritation, better sleep, and improved quality of life while the underlying illness is treated.
Recommended Dosage and Administration
Standard Dosage
For adults and children over 10 years old, the typical dosage is:

Maximum daily dose should not exceed 600 mg.
The medication is available in soft gelatin capsules, typically 100 mg or 200 mg in strength. It is important that capsules are swallowed whole—do not chew, crush, or dissolve—as this may result in a sudden release of the drug, causing potentially serious side effects.
