How does dextromethorphan hydrobromide + menthol work?
Dextromethorphan acts in the brain to raise the threshold that triggers coughing. Menthol provides a cooling, soothing sensation and may reduce perceived upper-airway irritation and congestion. It controls symptoms rather than treating the cough’s cause.

Shake the bottle vigorously, measure the syrup accurately and swallow it by mouth. Follow the pack directions and do not exceed the label instructions.
Use an appropriate measuring device rather than a household spoon.
The syrup contains sucrose, ethanol and sodium benzoate.
Ask a pharmacist before use if you have asthma or take other medicines.
Do not use it for a productive or persistent cough without clinical advice.

dextromethorphan hydrobromide + menthol in pregnancy
Safety evidence for this product in human pregnancy is limited. Ask a pharmacist, midwife or doctor before use. A controlled study of dextromethorphan did not find an increased rate of major malformations, but this does not establish the safety of this combination.
dextromethorphan hydrobromide + menthol while breastfeeding
The selected product should be avoided during breastfeeding because product-specific information is insufficient. A small study estimated low infant exposure to dextromethorphan through milk, but did not establish this combination’s safety. Discuss alternatives with a pharmacist or prescriber, especially for a premature or unwell infant.
dextromethorphan hydrobromide + menthol interactions
Check all prescription, non-prescription and recreational substances before use. Important interactions include:
Monoamine oxidase inhibitors (MAOIs)
Do not combine with current or recent MAOI treatment because a serious interaction, including serotonin toxicity, may occur.
Serotonergic medicines, including SSRIs
Combining them can increase the risk of potentially life-threatening serotonin syndrome.
Potent CYP2D6 inhibitors, including fluoxetine, paroxetine, quinidine and terbinafine
These can substantially increase dextromethorphan exposure and the risk of neurological effects, respiratory depression and serotonin syndrome.
