Get Dimetapp Online

Dimetapp is used to relieve symptoms of the common cold, hay fever, and upper respiratory allergies, including nasal congestion, runny nose, sneezing, and cough. It combines three active ingredients: brompheniramine (antihistamine), dextromethorphan (cough suppressant), and pseudoephedrine (decongestant).

Brompheniramine blocks histamine H1 receptors to reduce sneezing and runny nose. Dextromethorphan acts on the cough center in the brain to suppress the urge to cough. Pseudoephedrine constricts blood vessels in the nasal passages to reduce swelling and congestion.

Dimetapp should be avoided by people with uncontrolled high blood pressure, severe coronary artery disease, narrow-angle glaucoma, urinary retention, or those taking monoamine oxidase inhibitors (MAOIs). Pregnant or breastfeeding patients should consult their physician before use. A full medical review is completed before any prescription is issued.

Yes. Brompheniramine is a first-generation antihistamine that can cause drowsiness. Patients are advised not to drive or operate heavy machinery until they know how the medication affects them. Alcohol and other central nervous system depressants may increase this effect.

Dosing varies by formulation and the prescribing physician's recommendation. Patients should follow the specific instructions provided on their prescription label. Do not exceed the recommended dose, as higher amounts of pseudoephedrine and dextromethorphan can cause serious side effects.
