hydrocodone - phenylephrine
How does this medication work? What will it do for me?
This medication contains two ingredients, hydrocodone and phenylephrine. Hydrocodone belongs to the family of medications called antitussives (cough suppressants), and phenylephrine belongs to the family of medications called decongestants (congestion relievers).
Hydrocodone helps to suppress cough by affecting the cough centre in the brain. Hydrocodone is a narcotic medication and so can be habit-forming if taken for long periods. Phenylephrine works by narrowing blood vessels in the nasal passages and helps to relieve nasal stuffiness.
