Sinarest Tablet: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

Sinarest Tablet is a combination medicine containing chlorpheniramine maleate, paracetamol, and phenylephrine. It is used for short-term relief of cold, flu, and allergy symptoms such as congestion, sneezing, fever, and sinus pain while the body recovers. It belongs to the upper respiratory combination drug class, acting as an antihistamine, analgesic/antipyretic, and decongestant together.

What is Sinarest Tablet

Sinarest is a combination medicine that contains three ingredients: paracetamol (a pain reliever and fever reducer), phenylephrine (a nasal decongestant), and chlorpheniramine maleate (an antihistamine). It is used for short-term relief of cold, flu, and allergy symptoms while the body recovers.

Sinarest Tablet uses

• Fever, body aches, and shivering from colds and flu
• Used alongside antibiotics in sinusitis, tonsillitis, and middle ear infection (otitis media)

Benefits of Sinarest Tablet

• Helps manage fever, headache, and body discomfort from colds
• May support better rest and recovery by easing respiratory discomfort

How Sinarest Tablet works

Sinarest combines three medicines that each target a different symptom. Paracetamol reduces pain and fever by acting on the brain's pain and temperature control centers. Phenylephrine narrows swollen blood vessels in the nose to relieve stuffiness and reduce mucus. Chlorpheniramine blocks histamine, the substance in the body that causes sneezing, runny nose, and watery eyes.

Sinarest Tablet dosage

Swallow the tablet whole with a full glass of water; do not crush, chew, or break it. It can be taken with or without food, though taking it after a light meal may help if you have a sensitive stomach. Follow the exact dose and duration your doctor or pharmacist prescribes; do not take more than recommended or for longer than advised. This medicine is usually meant for short-term use until symptoms clear up. It is not recommended for children below 4 years of age; consult a doctor before giving it to a child. If a dose is missed, take it as soon as you remember, but skip it if it is almost time for the next dose; do not double up. Stop taking it and consult your doctor if symptoms do not improve within 5 to 7 days, or if fever gets worse.
