Cough suppressants help to stop the cough reflex and are good options for dry coughs. They do not treat the underlying reason for coughing but provide relief so you can rest.
Cough suppressants include both prescription and over-the-counter options. Dextromethorphan is available over the counter and is found in products like Delsym or Robitussin.
Benzonatate is a non-narcotic prescription option for suppressing cough. It numbs the stretch receptors in the lungs and airways to prevent coughing. It starts to work in about 20 minutes and can last up to eight hours.
