codeine / guaifenesin

Generic Cheratussin AC
Used for Cough

Codeine/guaifenesin is a cough syrup that contains an expectorant and an opioid. It's used to help loosen mucus and calm coughs in adults and older children. Codeine/guaifenesin is taken by mouth, typically every 4 hours as needed. But it's meant for short-term use only because it contains codeine, which is a controlled substance and can be habit-forming. Some side effects of codeine/guaifenesin include sleepiness and nausea. Brand name Cheratussin AC has been discontinued.

Risks and warnings for Codeine/guaifenesin

Codeine/guaifenesin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Potential for addiction and misuse

  • Risk factors: Personal or family history of alcohol or substance use disorder | Personal or family history of mental health problems

Codeine/guaifenesin is a controlled substance because it contains codeine, which has a risk for addiction and misuse. Take the medication exactly as prescribed. Taking more than the prescribed amount of codeine/guaifenesin raises the risk for serious and possibly life-threatening side effects, such as dangerously slow breathing, inability to stay awake, and opioid overdose. Your healthcare provider will prescribe the lowest amount of codeine/guaifenesin that's necessary to manage your pain for the shortest period of time possible. If you've been taking medication for 7 days and don't feel any better, contact your provider to discuss alternatives.

Short-term use only

Codeine/guaifenesin is for short-term treatment of cough only. Taking it longer than recommended can raise the risk for dependence and addiction, as well as the risk for side effects, like breathing problems. Codeine/guaifenesin isn't meant to ease cough from chronic (long-term) conditions such as asthma, emphysema, and chronic bronchitis. It's also not meant to help with cough from smoking. If you have any of these conditions, speak to your provider because they'll likely make other recommendations.

Also, you should stop taking Codeine/guaifenesin and talk to your provider if your cough lasts longer than 7 days, if it stops and returns, or if you develop other symptoms such as a fever, rash, or headache that doesn't go away. These can be signs of a more serious condition that needs more medical attention.

Not for children under 12 years old

The FDA issued a warning against children ages 12 years and under taking codeine medications for cough. This is because codeine medications can raise the risk of serious side effects, including life-threatening breathing problems, especially in children. If your child needs a cough medication, speak to your child's provider or your pharmacist to learn about safer alternatives.

Dangerous interactions

  • Risk factors: People taking other medications that cause sleepiness or slow down breathing | Drinking alcohol while taking codeine/guaifenesin

Taking codeine/guaifenesin with benzodiazepines, opioids, sleeping medications, or alcohol can cause you to be extremely sleepy or have trouble breathing. This can be life-threatening and even lead to death. Don't drink alcohol while taking codeine/guaifenesin. If you regularly take other medications that cause drowsiness or affect breathing, discuss alternatives with your provider. There are safer options for treating a cough.
