About Dextromethorphan Hydrobromide
Indications of Dextromethorphan Hydrobromide
Dextromethorphan Hydrobromide is indicated for the temporary relief of cough caused by minor throat and bronchial irritation, such as that occurring with the common cold or exposure to inhaled irritants.
Evidence-based classification of use
- Established/OTC-approved use: Symptomatic relief of a dry, nonproductive cough associated with upper respiratory tract infections (common cold) or minor throat/bronchial irritation.
- Not indicated for: Chronic or persistent cough associated with smoking, asthma, chronic bronchitis, or emphysema, or a cough that is accompanied by excessive phlegm (productive cough), unless specifically directed by a physician.
- Combination products: Dextromethorphan Hydrobromide is frequently formulated together with expectorants (e.g. guaifenesin), antihistamines, or decongestants for multi-symptom cold and flu relief; such combination use should follow the specific combination product's labeling.
Dextromethorphan Hydrobromide does not treat the underlying cause of cough and is intended only for short-term symptomatic relief.

Dosing of Dextromethorphan Hydrobromide is generally based on age for OTC use.

Frequently Asked Questions about Dextromethorphan Hydrobromide
What is Dextromethorphan Hydrobromide used for?
Dextromethorphan Hydrobromide is used for the temporary relief of a dry, nonproductive cough caused by minor throat and bronchial irritation, such as that associated with the common cold. It does not treat the underlying infection or cause of the cough.
Can I take Dextromethorphan Hydrobromide with other cold and cough medicines?
Many combination cold and flu products already contain Dextromethorphan Hydrobromide. Taking additional products that also contain Dextromethorphan Hydrobromide can lead to an unintentional overdose. Always check the active ingredients of all products before combining them, and consult a pharmacist or physician if unsure.
Is it safe to take Dextromethorphan Hydrobromide with antidepressants?
Combining Dextromethorphan Hydrobromide with monoamine oxidase inhibitors (MAOIs) is strictly contraindicated because it can cause serotonin syndrome, a potentially life-threatening reaction. Combining Dextromethorphan Hydrobromide with other serotonergic antidepressants such as SSRIs or SNRIs also increases the risk of serotonin syndrome and should only be done under medical supervision. Always inform your physician about all medications you are taking.
Can children take Dextromethorphan Hydrobromide?
Dextromethorphan Hydrobromide may be used in children 6 years and older at age-appropriate OTC doses. Use in children 4 to under 6 years should only occur under a physician's direction. Dextromethorphan Hydrobromide is not recommended for children under 4 years of age because safety and efficacy have not been established in this age group, and there is a risk of misuse and serious adverse effects.
What should I do if I miss a dose or think I've taken too much Dextromethorphan Hydrobromide?
Dextromethorphan Hydrobromide is typically taken as needed for cough rather than on a fixed schedule, so a missed dose is usually not a concern. However, if an overdose of Dextromethorphan Hydrobromide is suspected — with symptoms such as confusion, hallucinations, rapid heartbeat, or loss of coordination — seek immediate medical attention or contact a poison control center right away.
Is Dextromethorphan Hydrobromide safe during pregnancy or breastfeeding?
Data on Dextromethorphan Hydrobromide use during pregnancy and breastfeeding are limited. Dextromethorphan Hydrobromide should be used during pregnancy or lactation only if clearly needed, after the potential benefits and risks have been discussed with a physician.
