When foreign bodies irritate your nose, throat and lungs, your body reacts to defend you and expel the invaders. Blood vessels in the lining of your nose swell up, causing nasal congestion and mucus. Mucus goes into your lungs. Your central nervous system notifies your brain about this congestion. Your brain, in turn, issues an order to your lungs that they should cough forcefully enough to expel the mucus. While these physiological actions are normal and necessary, they can interfere with sleep, work and studies. Codeine works on the part of the brain responsible for the cough reflex; codeine makes your brain unaware of the need to cough. Guaifenesin is an expectorant that thins mucus congestion to make it easier to cough up and out. Phenylephrine constricts the blood vessels in the linings of your throat and lungs in a way that reduces stuffiness.

Taking high doses of opioids such as codeine can result in physical dependence, which means you must continue taking the drug to avoid experiencing unpleasant withdrawal symptoms. Withdrawal symptoms feel like a very bad flu. 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. Drug dependence and withdrawal are physical processes, not moral compasses. 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. The physical discomfort associated with withdrawal symptoms may prohibit quitting this drug without the help of rehabilitation specialists.
Rehabilitation specialists use medications to detoxify your body from the effects of codeine use and supportive care to help you cope with any other psychological or social problems associated with your codeine use. During rehabilitation, doctors will administer medications to ease withdrawal symptoms and cleanse the opioid from your body, speeding restoration of your chemical balance. Rapid detox is a new, humane way method of detoxifying your system. Physicians administer sedatives and anesthesia along with the regular detoxification medications; you are sedated during withdrawal, unaware of the pleasant flu-like symptoms of withdrawal. Refreshed and stabilized, you are already finished with the physically demanding part of rehabilitation when you awaken.
