Dextromethorphan Hydrochloride
DEXTROMETHORPHAN HYDROCHLORIDE
Overview
Dextromethorphan hydrochloride is a commonly used medicine that helps reduce coughing. It’s found in many over-the-counter cold and flu remedies. While it doesn’t treat the root cause of cough (like an infection), it helps give relief by quieting the urge to cough, especially when the cough is dry or irritating.
Classification
Cough Suppressant (Antitussive)
Uses
Eases dry or non-productive coughs
Provides temporary relief from throat irritation due to coughing
Often included in cold, flu, or allergy medications
How It Works
Dextromethorphan works by acting on the brain’s cough center—specifically, it affects signals in the part of the brain that triggers coughing. This helps reduce the frequency and intensity of coughs, allowing better rest and less throat discomfort.
Dosage
As prescribed by your doctor.
Side effects
Some people may experience:
Drowsiness or dizziness
Nausea or stomach upset
Mild confusion or lightheadedness (with high doses or sensitivity)
Less commonly:
Allergic reactions such as rash or itching
Nervousness or restlessness
Changes in mood or behavior (especially if misused)
Precautions
Not recommended for persistent or chronic coughs (like those linked to asthma, smoking, or long-term lung issues) unless advised by a doctor
Should be used carefully in children (especially under 6), older adults, or those with liver problems
Avoid alcohol and other sedatives while using it, as they can increase drowsiness
Should not be combined with certain antidepressants (MAO inhibitors) due to risk of serious interactions
