What You Should Know About Dextromethorphan (If Zerotuss Contains This Ingredient)
If Zerotuss is a dextromethorphan-containing cough suppressant, the following general information applies:
Standard Dextromethorphan Dosing for Cough Suppression
- The generally recommended dosage of dextromethorphan in over-the-counter preparations is likely subtherapeutic 1
- Maximum cough reflex suppression occurs at 60 mg and can be prolonged 1
- The typical over-the-counter dose is lower than the 60 mg dose shown to provide optimal cough suppression 1
Important Safety Considerations
- Dextromethorphan has a reassuring safety profile, particularly relating to overdose in adults and children 2
- Adverse drug reactions are infrequent and usually not severe, with predominant symptoms being dose-related neurological, cardiovascular, and gastrointestinal disturbances 2
- Particular safety concerns arise when monoamine oxidase inhibiting (MAOI) drugs and dextromethorphan are coadministered 2
- Care must be taken when recommending dextromethorphan at higher doses if combined preparations contain other ingredients such as paracetamol 1
Clinical Efficacy
- Dextromethorphan is effective in suppressing acute cough and has been shown to be superior to codeine in reducing cough intensity 3
- It lacks side effects, is safe even in overdose, and has non-narcotic status 3
Critical Action Required
You must consult the actual product label or package insert for Zerotuss to obtain accurate dosing information, as brand-name products may contain varying concentrations of active ingredients and different formulations that affect appropriate dosing.
