Deconsal DM (phenylephrine, pyrilamine maleate, and dextromethorphan hbr) Tannate Chewable Tablets are an antihistamine/nasal decongestant/antitussive combination used for the symptomatic relief of head cold with a runny nose (coryza), nasal congestion, and cough associated with the common cold, sinusitis, allergic rhinitis, and other upper respiratory tract conditions. This medication is available in generic form. Common side effects include drowsiness, sedation, dry mucus membranes, and gastrointestinal disturbances.
The dose of Deconsal DM for children 12 years and older and adults is 1 to 2 tablets, every 12 hours; 6 to 12 years of age - 1/4 to 1 tablet, every 12 hours. Deconsal DM may interact with MAO inhibitors. Tell your doctor all medications and supplements you use. During pregnancy, Deconsal DM should be used only if prescribed. Because of the higher risk of intolerance of antihistamines in small infants generally, and in newborns and prematures in particular, Deconsal DM should not be used while breastfeeding.
