Available 30 mg Dextromethorphan Formulations in India
I cannot provide specific brand names or formulations of 30 mg dextromethorphan products available in India, as the evidence provided does not contain information about Indian pharmaceutical market products, brand names, or country-specific drug availability.
What the Evidence Does Support About 30 mg Dextromethorphan Dosing
The American College of Chest Physicians and multiple international guidelines recommend dextromethorphan at 10-15 mg three to four times daily (total 30-60 mg per day), with a maximum daily dose of 120 mg for effective cough suppression. 1, 2
Standard Dosing Regimens Containing 30 mg Total Daily Dose
A 30 mg total daily dose can be achieved by taking 10 mg three times daily or 15 mg twice daily, which represents the lower end of the therapeutic range recommended by the CHEST expert panel 1
However, standard over-the-counter doses are often subtherapeutic; maximum cough reflex suppression occurs at 60 mg single doses, which is higher than typically found in OTC preparations 2
Clinical Considerations for 30 mg Dosing
A single 30 mg dose of dextromethorphan showed minimal clinical benefit in a randomized controlled trial of patients with acute upper respiratory tract infection, with little difference from placebo 3
For optimal cough suppression, doses of 30-60 mg per administration are recommended rather than 30 mg total daily, according to multiple guideline sources 2, 4
A bedtime dose of 15-30 mg may help suppress nocturnal cough and promote undisturbed sleep, as suggested by the American College of Chest Physicians 2
Important Safety Considerations
Exercise caution with combination preparations, as many products contain additional ingredients like acetaminophen that could reach toxic levels if dextromethorphan is dosed appropriately 1, 2
Dextromethorphan has a superior safety profile compared to codeine-based antitussives, with no risk of physical dependence and fewer adverse effects 2, 4
Common Pitfall to Avoid
- Prescribing subtherapeutic doses below 30 mg per administration will likely fail to provide adequate cough relief, as the dose-response relationship shows maximum suppression at 60 mg 2, 4
