What are the side effects of Dextromethorphan?

Dextromethorphan is a commonly used cough suppressant found in various over-the-counter medications. Even though Dextromethorphan is primarily safe when used as prescribed, you should know a few things before using medicine containing this ingredient. 

Dextromethorphan can have adverse effects on the human body, ranging from moderate to severe, just like any medication. Knowing the potential negative effects can help people choose whether to take this drug or look for alternate treatments. We’ll look at possible dextromethorphan side effects in this post and what you should know about them.

What is Dextromethorphan?

Dextromethorphan (DXM) is a suppressing agent for coughing commonly used in over-the-counter cough medicines. Despite having a molecular similarity to opiates and being an artificial variant of codeine, it doesn’t possess similar pain-alleviating effects. To stop coughs brought on by the flu, the cold, and other respiratory diseases, DXM works by inhibiting the brain’s cough reflex.

Common Side Effects

Dextromethorphan’s most typical adverse effects include:

Mild Stimulation and Exhilaration

Mild stimulation and exhilaration are two of Dextromethorphan’s most often reported adverse effects. While some people might find these sensations enjoyable, it’s critical to remember that DXM is not intended for recreational use, and abuse of it might have negative repercussions.

Hallucinations and Distorted Visual Perception

Dextromethorphan can create hallucinations and distorted vision at higher doses, which can be terrifying. People who use DXM recreationally occasionally seek out these symptoms. Hallucinations and altered perceptions, however, can be risky, mainly if someone is operating a vehicle or large machinery.

Sweating, Nausea, and Agitation

Dextromethorphan can have physical side effects such as sweat, nausea, irritability, and psychological adverse effects. Increased doses may lead to more frequent uncomfortable and unpleasant sensations.

High Blood Pressure

High blood pressure is another possible adverse effect of Dextromethorphan. It can be particularly problematic for those with cardiovascular issues, as it might raise their likelihood of a cardiac event or stroke.

Rare Side Effects of Dextromethorphan

Dextromethorphan can occasionally cause more severe adverse effects in some individuals. These may consist of the following:


Rarely, Dextromethorphan can result in seizures, which are more likely to happen if you take the drug in higher dosages.

Allergic Reactions

Dextromethorphan allergy symptoms include hives, itchiness, inflammation, and breathing difficulties for some people. Consult a doctor immediately if you encounter these side effects after taking Dextromethorphan.

Risks of DXM Abuse

When taken as prescribed, Dextromethorphan is a powerful cough suppressant; however, misusing the medication can have adverse effects. Robotripping refers to the misuse and recreational use of DXM-containing substances. Young individuals frequently misuse DXM, taking excessive dosages to get high or experiencing delusions or other emotional effects. Long-term dextromethorphan misuse can result in addiction, withdrawal symptoms, and liver and kidney damage.


It’s vital to remember that Dextromethorphan, a frequent ingredient in cold and flu medications, can have dangerous adverse effects. After taking Dextromethorphan, you must immediately consult a doctor if you suffer any of the symptoms listed in this post. Talk to a healthcare provider or a mental health professional if you have any concerns about the possibility of abuse or addiction. You can safely and successfully manage your symptoms with the proper assistance and treatment.
