Coldnac 650/10/4/30 Tab 10'S

Coldnac 650/10/4/30 Tab is used to treat the common cold and allergic symptoms like sneezing, watery eyes, or itchy/watery nose and throat. The common cold is a respiratory illness affecting the nose and throat, mostly caused by viruses known as 'rhinovirus.' The virus attacks the body through the mouth, nose, or eyes and spreads quickly through droplets in the air when a person who is sick sneezes, coughs, or talks.

Coldnac 650/10/4/30 Tab is composed of four medicines, namely: Chlorpheniramine (anti-histamine), Phenylephrine (decongestant), Paracetamol (mild analgesic and antipyretic), and Caffeine (a stimulant).  Chlorpheniramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps in shrinking the blood vessels in the nasal passage, thereby reducing the stuffy nose. Paracetamol is an analgesic (relieves pain) and antipyretic (reduces fever) that works by inhibiting the production of certain chemical messengers in the brain known as 'prostaglandins' responsible for pain and fever. Caffeine acts as a common stimulant, which decreases sleepiness caused by Chlorpheniramine and speeds up the action of all the medicines present in Coldnac 650/10/4/30 Tab .
