Cough Medicine and Cough Syrups

Got a cold and need medicine for a nagging cough? While there is no quick fix for your cough, some over-the-counter (OTC) cough syrups and cough medicines may give you relief.

Three types of cough medicines are available OTC for the temporary relief of cough due to a cold or bronchitis. These cough medicines include cough suppressants, oral expectorants, and topical (externally applied) drugs.

Who Should not Take Cough Medicine or Cough Syrup?

Often, doctors believe that a cough from a cold should not be treated. Coughing up mucus may help keep your lungs clear. This is especially true if you smoke or have asthma or emphysema.

If you take a monoamine oxidase inhibitor (MAOI), a type of prescription drug used to treat depression and other conditions, it’s important to talk to your doctor or pharmacist before taking dextromethorphan, commonly noted as DM on cough syrups and cough medicines. In addition, some combination cold and cough medicines contain decongestants. If you have high blood pressure or heart disease, avoid taking these drugs. Decongestants can raise blood pressure.

The most important key is to understand how the cough syrup or cough medicine works. That includes knowing what the side effects are. Then talk to your doctor if you have concerns about your cough or cough medicine. Trust your doctor to make the best decision with your overall health in mind.

Which Cough Syrups and Cough Medicines Suppress Coughing?

Cough suppressants relieve your cough by blocking the cough reflex.

Dextromethorphan, or DM, is the most common cough suppressant. Dextromethorphan does not have the pain-relieving and addictive properties of codeine, a narcotic cough suppressant that requires a doctor’s prescription.

If you have a dry, hacking cough, dextromethorphan may give you relief. Generally, these cough syrups and cough medicines are not used to suppress a cough where you cough up mucus. A productive cough helps clear secretions and mucus from the airways. Talk to your doctor if you have a productive cough that’s preventing you from sleeping.

How Do Expectorants Stop a Cough?

An expectorant is a drug that thins mucus so you can cough it up easier. While many experts feel that drinking water is the most effective way to loosen mucus, you can also use such medications as guaifenesin to thin mucus so it can be cleared from the airway. Clearing thick mucus from the airways can decrease coughing. The most frequent side effect of expectorants is nausea and vomiting.

Do Topical Cough Medicines Stop Coughs?

Camphor and menthol are commonly used topical cough medicines. These natural, aromatic cough medicines are rubbed on the throat and the chest. The anesthetic action of their vapors is thought to ease coughing and soothe stuffiness from a cold.

Camphor and menthol cough medicines are also available for steam inhalation. Menthol is available in lozenges and in compressed tablets.

What’s a Combination Cold and Cough Medicine?

Many OTC cold and cough syrups and cough medicines contain a cough suppressant (dextromethorphan) plus an expectorant (guaifenesin) along with other cold medicines and pain relievers. The combination cold and cough medicine may contain an antihistamine, a decongestant, and a pain reliever in addition to the cough suppressant and/or expectorant. The combination of medicines may give optimal relief if you have multiple cold symptoms, such as body aches, coughs, and congestion. The downside of the combination cold medicines is that you may be taking medication that you don’t need, depending on your symptoms.
