Benzonatate

Description

Benzonatate is an oral medication used for the suppression of coughs. It has an anaesthetic which has a numbing effect not unlike that of benzocaine. Essentially it numbs the stretch sensors found within the lungs. Coughs are caused by the action of stretch sensors in conjunction with regular breathing. The drug will normally have an effect within 15 to 20 minutes of taking it. The effects will last for just about 3 hours. Benzonatate is not to be confused with narcotics like codeine which is also used for cough suppression. Benzonatate has been on the market since 1958 when it was approved by the FDA.

Dosing

Benzonatate is sold as a liquid-filled capsule (perle) and a normal capsule that is taken orally. It is generally taken three times per day as required. It is important that you follow dosing instructions and ask your pharmacist to clarify any information related to the drug that you do not understand. Take the drug in the manner it is prescribed. Ensure that you do not take more or less than the recommended amount as this will affect the efficacy of the drug.

Take the capsule with water to aid swallowing. Do not chew or suck on the capsule. If this medication is accidentally released in the mouth it will cause numbness of the tongue and possible choking.
