benzonatate: Frequently Asked Questions Answered

What is Benzonatate?

Benzonatate is a drug useful for relieving coughs and hiccups in people above the age of 10. It is mainly useful against coughs caused by a cold or influenza. Benzonatate is not useful for treating coughs caused by smoking, asthma, emphysema or other chronic conditions that increase mucus or phlegm levels. It is a prescription medication available as a capsule and a liquid-filled capsule. Benzonatate acts on the lungs and breathing pathways to relieve cough. It affects a specific part of the brain and reduces the urge to cough.  

What are the uses of Benzonatate?

Generally, it does not relieve cough with high mucus or phlegm and works well only with a cough caused by a cold or influenza. Benzonatate is also useful for treating hiccups.

Frequently Asked Questions about benzonatate

1.How long does it take for Benzonatate to get rid of a cough?

Benzonatate makes the cough reflex less active. Once you take the capsule, it starts working in 15 to 20 minutes, and the effect lasts for about 3 to 8 hours. It is used for coughs caused by a cold or influenza and not for chronic coughs caused by smoking, asthma and emphysema.

2. Does Benzonatate loosen mucus?

No, Benzonatate does not loosen mucus. Benzonatate belongs to a class of medicines called antitussives (cough suppressants). In patients with thick mucus or who are unable to cough up mucus, expectorants are used to loosen the mucus. If you are coughing with mucus, this might not be the best treatment.

3. Does Benzonatate increase blood pressure?

Benzonatate can sometimes lead to severe hypersensitivity reactions. Although rare, you can experience anaphylaxis, a hypersensitivity condition characterised by nausea, vomiting, trouble breathing, skin rash and a rapid drop in blood pressure called shock that may be potentially lethal. In patients with high blood pressure, decongestants can increase blood pressure and speed up the heart rate.

4. Is Benzonatate a sedative?
