Coricidin HBP

**Coricidin HBP** is a brand line of over-the-counter combination medications designed for cold and flu symptom relief, particularly safe for individuals with high blood pressure as it contains no decongestants. Different formulations include **Coricidin HBP Cough & Cold** (chlorpheniramine maleate 4 mg as antihistamine + dextromethorphan hydrobromide 30 mg as cough suppressant), **Coricidin HBP Maximum Strength Multi-Symptom Flu** (acetaminophen 325-500 mg as pain reliever/fever reducer + chlorpheniramine maleate 2 mg + dextromethorphan HBr 10-15 mg), and others like Chest Congestion (dextromethorphan + guaifenesin). These act via analgesia (acetaminophen inhibits prostaglandin synthesis), H1 receptor antagonism (chlorpheniramine blocks histamine to reduce rhinorrhea/sneezing), antitussive suppression of cough reflex (dextromethorphan acts on sigma-1 receptors in the medulla), and expectoration (guaifenesin increases respiratory secretions). Originally introduced by Schering-Plough in 1949, now manufactured by Bayer HealthCare LLC, it provides temporary relief for cough, congestion, pain, fever, and runny nose in adults/children ≥12 years, taken orally every 4-6 hours with liver warnings due to acetaminophen.[1][2][4][5][7][8][11]
