Dextromethorphan: What Is It?

Dextromethorphan is an active ingredient found in many cough syrups, capsules, tablets, and other cold-and-cough products. It mainly helps control a dry or irritating cough. It does not kill bacteria or address the underlying cause of an infection like antibiotics do.

Some cold medicines also combine dextromethorphan with other ingredients to treat multiple symptoms, such as a stuffy nose, fever, or congestion. That’s why you should always read the product label before taking more than one cold or cough medicine.

What Is Dextromethorphan Used For?

The main purpose of dextromethorphan in relieving cough is to decrease coughing when short-term symptom control is needed.

They can be used for:

• Dry cough: Helps to relieve coughing without bringing up mucus.
• Cough due to common cold: May give temporary relief from irritating cough symptoms.
• Throat irritation—An irritated throat might feel better if you decrease frequent coughing.
• Nighttime Coughing If appropriate, cough suppression can help someone get rest more comfortably.

However, dextromethorphan is not effective for all respiratory problems. If you have a cough due to asthma, pneumonia, or another underlying medical problem, you may need different treatment.

How Dextromethorphan Works?

Dextromethorphan depresses the cough reflex by acting on the central nervous system. Simply put, it depresses the cough reflex of the brain.

Some people have fewer coughing episodes when they take the medicine as directed. The results can differ from one person to another, depending on the cause of the cough, the formulation, and the person’s health.

Dextromethorphan does not remove mucus from the lungs or treat the infection that causes a cold. Thus, the choice of an appropriate therapy is determined by the symptoms and the underlying cause.

How to Use Dextromethorphan Safely

Follow the product label directions or those provided by a healthcare professional. The amount you should take depends on the formulation, the strength, the age of the person, and other individual factors.

Remember the following safety tips:

• Use the measuring device that comes with the medicine to measure liquid medicine, not a household spoon.
• Active ingredients and recommended dosing interval can be found on the label.
• Never take more than the recommended dose.
• Do not mix several cold medications unless you have checked that they contain the same ingredients.
• Check with your healthcare provider before giving cough medicine to a child.
• If you have a long-lasting medical condition or are taking other medicines, consult a pharmacist or doctor.

Moreover, a bigger dose does not make the medicine safer or more effective. Too much of it can do serious damage.

Possible Side Effects of Dextromethorphan

Dextromethorphan may cause side effects. Do not be alarmed. Not everyone has them, and they can vary in severity.

Possible side effects are

• Lightheadedness or dizziness
• Sleepiness
• Nausea
• Nausea and vomiting
• Stomach upset

Too much in some cases can cause confusion, agitation, hallucinations, poor coordination, or other serious effects.

If you suspect an overdose or are experiencing serious symptoms, please call your local emergency services immediately. Don’t wait for symptoms to escalate before seeking help.

Precautions and Interactions with Drugs

Before you use dextromethorphan cough medicine, tell your health care professional about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

In particular, dextromethorphan may interact with monoamine oxidase inhibitors (MAOIs), which are some medications used to treat depression or other conditions. Some interactions may result in dangerous reactions. Do check the medicine label for restrictions—and if unsure, ask a pharmacist.

Furthermore, some antidepressants and other medications can increase the risk of interactions or side effects. Those with liver conditions, pregnant women, and those who are nursing should consult a professional before using.

Do not use dextromethorphan for a cough that lingers or is not explained without medical advice.

When to Visit a Doctor?

While an occasional cough will usually get better with time, some symptoms need medical attention.

When to see a doctor: If your cough sticks around for a long time, comes back a lot, or gets worse, you should see a health care provider. If you develop a high temperature, chest pain, breathing problems, or coughing up blood, you should also seek advice.

Severe breathing problems, fainting, or symptoms of a major overdose require immediate emergency medical help.
