COLDAID TABLET belongs to a class of medication called 'cough and cold medications' primarily 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.

COLDAID TABLET 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 COLDAID TABLET.

Take COLDAID TABLET as prescribed. Your doctor will recommend how often you take COLDAID TABLET based on your medical condition. Do not crush, chew, or break it. Your doctor will recommend how often you take COLDAID TABLET based on your medical condition. Some people may experience drowsiness, sleepiness, nausea, fatigue, difficulty in sleeping, headache. Everyone doesn't need to experience the above side effects. In some cases, COLDAID TABLET may cause a severe allergic skin reaction, probably due to paracetamol, which may disappear in some time.

Inform your doctor if you are pregnant, planning for pregnancy, or breastfeeding before starting COLDAID TABLET. If you have high blood pressure (hypertension),  liver or kidney disease, coronary artery disease (heart disease), avoid using COLDAID TABLET as it may worsen your existing condition and symptom. Consumption of alcohol should be avoided as it may lead to excessive drowsiness and sleepiness. Do not take COLDAID TABLET if you have taken any MAO inhibitor (anti-depressant medication like Isocarboxazid, Phenelzine, Selegiline, and Tranylcypromine) in the last 14 days. Intake of more than 4 gm of paracetamol can damage your liver, so it is better to avoid the use of COLDAID TABLET in severe liver damage. Cetirizine present in the COLDAID TABLET can make you sleepy, so do not drive or operate heavy machinery after taking COLDAID TABLET. Phenylephrine present in COLDAID TABLET should be used with caution in patients with occlusive vascular disease (nerve/artery blockage), including Raynaud's phenomenon (decreased blood flow to the fingers).
