Physicians prescribe codeine and guaifenesin to treat symptoms associated with upper respiratory infections or the common cold. Codeine is a cough suppressant while guaifenesin is an expectorant - it loosens up mucus congestion in your throat and lungs, making it easier to cough out. Use codeine and guaifenesin to relieve symptoms so you can sleep through the night, go to work or attend class. This product is not intended to treat coughs caused by smoking, asthma or emphysema.

Codeine and guaifenesin work together to reduce cough and congestion. Codeine works by acting directly on the part of your brain responsible for the cough reflex. Your brain is simply unaware of the need to cough. Guaifenesin thins mucus to make it easier to cough it out of your lungs and throat.

If you take high doses of codeine, or you use this drug for a long time, your body may grow physically dependent on this opioid. Dependence means your body relies on codeine to prevent symptoms of withdrawal. You may experience unpleasant, flu-like symptoms when you stop taking codeine. It takes some time for your body chemistry to return to normal. Withdrawal symptoms are a predictable, normal physiological reaction to your body's dependence on a chemical and not necessarily an indication of illicit or recreational drug abuse. Not everyone experiences withdrawal in exactly the same way. Sometimes people who had been given opioids in the hospital don't realize they are suffering from withdrawal and attribute the unpleasant physical symptoms to the flu. A person who has associated his symptoms with withdrawal might start craving codeine because he knows using the drug will ease his discomfort. Withdrawal symptoms may be so strong in some individuals that the physical discomfort prevents them from quitting codeine. More Information about Withdrawal from Codeine and Guaifenesin
Rehabilitation specialists combine supportive care and medications to detoxify your body from codeine use. Medications ease withdrawal symptoms and cleanse the opioid from your body to speed restoration of your chemical balance. Supportive care typically involves counseling and other social services to increase your chances for success. Rapid detox is a new, humane way method of detoxifying your system. Physicians administer sedatives and anesthesia along with the regular detoxification medications so that you are sedated during withdrawal, unaware of the pleasant flu-like symptoms that prevented you from quitting on your own. You awaken refreshed and stabilized, already finished with the physically demanding part of rehabilitation. Learn More About Codeine and Guaifenesin Detoxification Programs
