Relieving unproductive cough and reducing mucus in the chest due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.

Carbetapentane/Guaifenesin Sustained-Release Capsules is a cough suppressant and expectorant combination. The cough suppressant works in the brain to help decrease the cough reflex. The expectorant works by thinning mucus (phlegm) in the lungs, making it less sticky and easier to cough up. This makes coughs more productive.
