Dextromethorphan Hydrobromide is a non-opioid antitussive drug. It exerts its antitussive activity by acting on the cough center in the medulla oblongata, raising the threshold for the cough reflex. Levomenthol has mild local anesthetic and decongestant properties. Diphenhydramine Hydrochloride possesses antitussive, antihistaminic, anticholinergic properties.

Treatment of overdose should be symptomatic and supportive. Measures to promote rapid gastric emptying and in cases of acute poisoning the use of activated charcoal may be useful.

Pregnancy & Lactation

Pregnancy: Both Diphenhydramine Hydrochloride and Dextromethorphan Hydrobromide have been in widespread use for many years without apparent ill consequences. However, there is insufficient information on the effects of the administration of Dextromethorphan Hydrobromide during human pregnancy.

Lactation: It is not known whether dextromethorphan or its metabolites are excreted in breast milk. Diphenhydramine Hydrochloride is known to cross the placenta and has also been detected in breast milk. The syrup should therefore only be used when the potential benefit of treatment to the mother exceeds any possible hazards to the developing fetus or suckling infant.
