Guaifenesin / Codeine Side Effects

What should I watch for?

Use exactly as directed by your doctor or health care professional. Do not take more than the recommended dose. You may develop tolerance to this medicine if you take it for a long time. Tolerance means that you will get less cough relief with time. Tell your doctor or health care professional if your symptoms do not improve or if they get worse.

If you have been taking this medicine for a long time, do not suddenly stop taking it because you may develop a severe reaction. Your body becomes used to the medicine. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a drug for a nonmedical reason. If your doctor wants you to stop the medicine, the dose will be slowly lowered over time to avoid any side effects.

There are different types of narcotic medicines (opiates). If you take more than one type at the same time or if you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.

The medicine may cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your doctor or health care professional.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
