Used for Cough
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.

Last reviewed on October 11, 2023
Codeine/guaifenesin is a controlled substance, which means that it's more likely to be misused or cause dependence. There are federal and state laws that limit the amount of medication that can be prescribed or dispensed within a certain period of time.

What are the 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.

risk-warning

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.

    risk-warning

    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.

    risk-warning

    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.

    risk-warning

    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.

                  faqs

                  Frequently asked questions about Codeine/guaifenesin

                  Can I take ibuprofen (Motrin) with codeine/guaifenesin?
                  If you have a fever or body pain along with your cough symptoms, you can take ibuprofen (Advil) along with codeine/guaifenesin as long as your provider says it's safe. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID), and this class of medications might not be safe for those with kidney problems, stomach issues, or heart conditions.
                  Can I take acetaminophen (Tylenol) with codeine/guaifenesin?
                  Your provider might recommend acetaminophen (Tylenol) for you if you've a fever or body pain along with your cough symptoms. Look at the packaging of your acetaminophen (Tylenol) product for instructions on dosing. Keep in mind that the maximum daily dose of acetaminophen (Tylenol) is lower for people who have liver problems. Also, double check to make sure your acetaminophen (Tylenol) product doesn't already contain guaifenesin, which is commonly found in over-the-counter cold and flu medications.
                  Is codeine/guaifenesin a controlled substance?
                  Yes. Codeine/guaifenesin is a schedule V controlled substance, which means it has the potential for addiction and misuse. This is the same for all cough medicines with codeine.
                  Do you need a prescription for codeine/guaifenesin?
                  Yes, you need a prescription for codeine/guaifenesin in most states. Codeine/guaifenesin is considered a controlled substance by the U.S. Drug Enforcement Administration (DEA), but laws regarding controlled substances can differ from state to state. A prescription is required to purchase this medication in almost every state, but some states (e.g., Florida) allows adults 18 years and older to buy codeine/guaifenesin at the pharmacy counter without a prescription, though a photo ID is needed. Check with your pharmacist if you're not sure about the laws in your state.
                  Does codeine/guaifenesin make you drowsy?
                  Yes, drowsiness is one of the more common side effects of opioid-containing medications, including codeine/guaifenesin. Avoid driving or doing any activity the needs a lot of focus and attention while taking this medication until you know how it makes you feel. If codeine/guaifenesin is making it difficult for you to get through the day, your provider might only recommend it for nighttime cough. Ask them about non-drowsy cough medication options that are more appropriate for daytime.
                  Can I take codeine/guaifenesin long-term?
                  No, codeine/guaifenesin is meant for short-term cough relief only. Taking Codeine/guaifenesin long-term can raise the risk of it becoming habit-forming. If you don't feel any better after using this medication for 7 days, contact your provider. You might need more medical attention for your cough.
                  Can I take codeine/guaifenesin if I'm pregnant?
                  Let your provider know if you're pregnant or thinking of becoming pregnant. Codeine/guaifenesin isn't typically recommended during pregnancy because this medication can pass from mother to child and raise the risk for opioid dependence in an unborn baby. Speak with your provider about safer medication options or home remedies for treating a cough while you're pregnant.
