This combination of Paracetamol (325/500 mg), Phenylephrine HCl (5 mg), Caffeine (Anhydrous, 30 mg), and Diphenhydramine (25 mg) provides multi-symptom relief for cold, flu, and headache. Paracetamol is a pain reliever and fever reducer, helping to alleviate headache, body aches, and reduce fever. Phenylephrine HCl is a decongestant that constricts blood vessels in the nasal passages, relieving nasal congestion and improving breathing. Caffeine enhances the effectiveness of pain relievers like Paracetamol, providing faster relief from headache and boosting alertness. Diphenhydramine is an antihistamine that reduces symptoms like runny nose, sneezing, and itching, and also has a mild sedative effect to aid rest. Together, these ingredients offer effective relief from multiple symptoms, helping restore comfort and ease.
