6 Ways to Stop a Cough

Coughs can be irritating and disrupt your daily life. Although they can be caused by many things, coughs that are caused by respiratory infections such as colds and the flu can last three to eight weeks.

This article explains six options for relieving the symptoms of a cough.

Cough Suppressants

Over-the-counter (OTC) medications called cough suppressants provide relief by suppressing the reflex that causes a cough.

However, very little research has been done to prove that these medications actually provide any benefit. Some may have side effects. Most clinical trials involving over-the-counter cough suppressants have shown that they are not any more effective than doing nothing at all.

Expectorants

Expectorants, which also are available OTC, are different from cough suppressants because they don’t stop coughs. They work by thinning your mucus so it drains better. This helps you cough it up more easily.

Unlike cough suppressants, these medications have been proven in clinical studies to decrease secretions. This could reduce symptoms of coughing.

If the cough is caused by the common cold, your healthcare provider may prescribe a decongestant. These can dry up sinus secretions that cause post-nasal drip (which can make you cough).

Prescription Cough Medications

Prescription-strength cough suppressants are used to relieve severe coughs. These can interrupt daily activities and keep you awake at night. Your healthcare provider may prescribe one of these medications if OTC options are not effective.

Prescription cough medications include codeine, which is a narcotic. These drugs can cause side effects and can also be habit-forming.

Other Options

Other ways to relieve symptoms of a cough include:

Cough drops: Throat lozenges or cough drops containing menthol may help relieve coughs temporarily. Menthol acts as a mild anesthetic and can reduce the need to cough.

Humidifier: When you're sick with an upper respiratory illness, using a humidifier can help relieve symptoms. It puts extra moisture in the air, reducing irritation from dry air that can bother already sore throats and uncomfortable nasal passages.

Although using a humidifier won't make your cough go away, it could help reduce the irritation in your airways, meaning you may cough less frequently.

A spoonful of honey: In recent studies, honey has shown to be more effective than OTC cough medications at relieving coughs, especially in children. Just a spoonful of honey can coat the throat and calm a cough, at least periodically.

Summary

Coughs are a common symptom of many illnesses. While irritating, they help eliminate extra mucus from the airways and prevent it from getting trapped in the lungs, which can lead to complications like pneumonia. Symptoms of a cough can often be relieved by OTC medications and home remedies. In some cases, your healthcare provider may prescribe a stronger cough medicine.

A Word From Verywell

Most coughs will go away on their own in around a week. If your cough lingers for more than a few weeks or if it changes significantly, contact your healthcare provider. You may need to treat the underlying cause of a cough (such as pneumonia or bronchitis) instead of just trying to get relief from the symptoms.
