Dextromethorphan (dex-troe-meth-OR-fan) is used to relieve coughs due to colds or influenza (flu). It should not be used for chronic cough that occurs with smoking, asthma, or emphysema or when there is an unusually large amount of mucus or phlegm (flem) with the cough.

Dextromethorphan relieves cough by acting directly on the cough center in the brain.

This medicine is available without a prescription; however, your doctor may have special instructions on the proper use of this medicine for your medical condition.

Other medical problems

The presence of other medical problems may affect the use of dextromethorphan. Make sure you tell your doctor if you have any other medical problems, especially:

* Asthma—Since dextromethorphan decreases coughing, it makes it difficult to get rid of the mucus that collects in the lungs and airways during asthma
* Diabetes (sugar diabetes)—Some products contain sugar and may affect control of blood glucose monitoring
* Liver disease—Dextromethorphan may build up in the body and cause unwanted effects
* Chronic bronchitis or
* Emphysema or
* Mucus or phlegm with cough—Since dextromethorphan decreases coughing, it makes it difficult to get rid of the mucus that may collect in the lungs and airways with some diseases
* Slowed breathing—Dextromethorphan may slow the rate of breathing even further

Make certain your health care professional knows if you are on a low-sodium, low-sugar, or any other special diet. Most medicines contain more than their active ingredient, and many liquid medicines contain alcohol.
