What is Dextromethorphan and How Does it Work?

Dextromethorphan is a cough suppressant that is available over-the-counter. It is commonly used to relieve coughing associated with colds and flu. Dextromethorphan works by suppressing the cough reflex in the brain, which reduces the urge to cough.

Dextromethorphan is a synthetic derivative of morphine, which means it has similar effects to morphine but is less potent and less addictive. Unlike codeine, which is also used as a cough suppressant, dextromethorphan does not have analgesic (pain-relieving) effects.

Dextromethorphan is available in various forms, including tablets, capsules, and syrups. It is important to follow the instructions on the label of the product and not to exceed the recommended dose.

While dextromethorphan can be effective in relieving coughs, it can interact with other medications and health conditions. It is always recommended to consult a doctor or pharmacist before taking dextromethorphan, especially if you have any underlying health conditions or are taking other medications.
