hydrocodone - pyrilamine - phenylephrine - ammonium chloride
How does this medication work? What will it do for me?
Hydrocodone – pyrilamine – phenylephrine – ammonium chloride is no longer being manufactured for sale in Canada and is no longer available under any brand names. This article is being kept available for reference purposes only. If you are using this medication, speak with your doctor or pharmacist for information about your treatment options.
This medication contains four different medicinal ingredients. Hydrocodone belongs to the family of medications known as antitussives (cough suppressants). It helps to suppress cough by affecting the cough centre in the brain.
Phenylephrine belongs to the family of medications called decongestants (congestion relievers). It works by narrowing blood vessels in the nasal passages, helping to relieve nasal stuffiness.
Pyrilamine belongs to the family of medications called antihistamines. Pyrilamine works by drying up the excess fluid that leads to runny nose and watery eyes.
Together, these three ingredients help to control cough and relieve congestion due to colds and bacterial infections. Ammonium chloride is an expectorant that helps make mucus easier to cough up.
