Your doctor probably prescribed codeine, phenylephrine and dexchlorpheniramine to be taken on a regular schedule rather than as needed to control symptoms. If you miss a dose and it is a long time before the next scheduled dose, take the missed dose as soon as possible. If it is nearly time to take another dose and you can tolerate the symptoms, skip the missed dose and resume your normal schedule. Do not take extra doses to make up for missed doses.

Contact the prescribing physician if your symptoms do not go away after five to seven days or if your symptoms get worse. Do not take more than the prescribed dose in an effort to control your symptoms - this may lead to dangerous overdose. Do not continue taking this medication after your healthcare provider recommends stopping.

Action

Codeine is an antitussive, which means it suppresses a cough. Codeine works by acting directly on the part of the brain responsible for the cough reflex; codeine makes your brain unaware of the need to cough. Phenylephrine is a decongestant that works by constricting blood vessels inside the lining of nasal passages to reduce the sensation of a stuffy nose. Dexchlorpheniramine is an antihistamine. It works by blocking natural histamines that cause itchy and watery eyes, runny nose and sneezing. More About How Codeine, Phenylephrine and Dexchlorpheniramine Works

Withdrawal

When your body becomes dependent on a drug, you need to continue taking the drug to feel good. If you stop taking the drug, you experience withdrawal symptoms. Withdrawal symptoms are a natural physiologic response to the changing chemistry within your body. Experiencing withdrawal symptoms does not necessarily indicate criminal drug use - some people feel withdrawal symptoms after receiving pain killers in the hospital. A person with a physical dependence on drugs may feel withdrawal symptoms when he stops using the drug but he will not crave the drug unless he makes the cognitive connection between the withdrawal symptoms and the drug. Withdrawal symptoms include anxiety, irregular heartbeat, irritability, restlessness, trouble sleeping, and unusual sweating.

Detox

Drug dependence is a complex condition, frequently requiring the help of highly trained rehabilitation specialists to overcome. The most effective rehabilitative treatment programs address each aspect of the complicated syndrome of drug dependence, including overcoming withdrawal symptoms, cleansing the drug from your body and addressing any social issues that contribute to drug dependence. During the first phase of rehabilitation, physicians administer medication to detoxify and cleanse your body while easing your withdrawal symptoms. Once physically stabilized, you may choose to participate in a counseling program or other social services to address any issues that lead to or is the result of your dependence on drugs, such as family problems or legal issues. Rapid detox is state-of-the-art, humane and extremely effective way to overcome withdrawal. During rapid detox, specially trained physicians administer anesthesia and sedatives along with detoxification medications. You sleep through the withdrawal process, unaware of the unpleasant withdrawal symptoms. When you awaken, you will have no memory of the withdrawal process.
