Hydrocodone/guaifenesin

Hydrocodone/guaifenesin is a combination medication used in the treatment of symptoms caused by allergies, common cold, and respiratory illnesses such as bronchitis and pneumonia. It contains two active ingredients: hydrocodone, an opioid cough suppressant, and guaifenesin, an expectorant.

Composition

The medication is composed of two active ingredients. Hydrocodone is a semi-synthetic opioid derived from codeine, a natural substance extracted from the opium poppy. It works by acting on certain centers in the brain to stop the urge to cough. Guaifenesin is an expectorant that helps to loosen and thin mucus in the lungs, making it easier to cough up and clear the airways.

Uses

Hydrocodone/guaifenesin is used to relieve a cough caused by common cold or in people with respiratory illnesses such as bronchitis, pneumonia, and COPD. It should not be used in children under 6 years of age due to the risk of serious side effects such as slow/shallow breathing.

Side Effects

Common side effects of hydrocodone/guaifenesin include dizziness, lightheadedness, nausea, and vomiting. Serious side effects include slow/shallow breathing, severe drowsiness/dizziness, difficulty waking up, confusion, and hallucinations.

Precautions

Before taking hydrocodone/guaifenesin, tell your doctor or pharmacist if you are allergic to it; or to other opioids such as morphine or codeine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems.

Interactions
