Nuhist Tablet is a combination medication containing Caffeine (30mg), Diphenhydramine (25mg), Paracetamol (500mg), and Phenylephrine (5mg), formulated for the symptomatic relief of common cold, flu, and related conditions. Paracetamol acts as an analgesic and antipyretic, effectively reducing fever and alleviating mild to moderate pain. Diphenhydramine, an antihistamine with sedative properties, helps relieve allergic symptoms such as sneezing, runny nose, and nasal congestion, while also providing mild sedation to improve rest. Phenylephrine serves as a decongestant by constricting nasal blood vessels, thereby reducing nasal swelling and facilitating easier breathing. Caffeine is included to counteract the sedative effects of diphenhydramine and to enhance alertness. Nuhist Tablet is indicated for adults and children above 12 years experiencing headache, nasal congestion, fever, and allergic symptoms associated with upper respiratory tract infections. It should be used with caution in patients with hypertension, cardiovascular disorders, or hypersensitivity to any component. The medication is intended for short-term use, and patients are advised to follow the prescribed dosage and consult a healthcare professional if symptoms persist or worsen. Avoid concurrent use with other products containing paracetamol to prevent overdose.
