What is carbetapentane, phenylephrine, and pyrilamine (C-Tanna 12D, Tannate 12D S, Tannihist-12D, Tussi-12D, Tussi-12D S)?

Carbetapentane is a cough suppressant.

Pyrilamine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

The combination of carbetapentane, phenylephrine, and pyrilamine is used to treat runny or stuffy nose, sinus congestion, and cough caused by allergies, the common cold, or flu.

Carbetapentane, phenylephrine, and pyrilamine may also be used for other purposes not listed in this medication guide.
