Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Ushnol Sinus Tablet contains Chlorpheniramine Maleate (5mg) + Paracetamol (125mg) + Phenylephrine (5mg). It belongs to the Antihistamine / leukotriene antagonist, Para-aminophenol derivative and Expectorant / mucolytic / bronchodilator class of medicines.
Treatment of Common cold
Ushnol Sinus Tablet is a combination of three medicines: chlorpheniramine, paracetamol, and phenylephrine. It relieves common cold symptoms. Chlorpheniramine is an antiallergic that relieves allergy symptoms like a runny nose, watery eyes, and sneezing. Paracetamol is an analgesic (pain reliever) and antipyretic (fever reducer). It blocks the release of certain chemical messengers in the brain that are responsible for pain and fever. Phenylephrine is a nasal decongestant that narrows the small blood vessels, providing relief from congestion or stuffiness in the nose.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Ushnol Sinus Tablet may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Ushnol Sinus Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause severe drowsiness, a fast heartbeat, confusion and, in children, agitation and fits. It can cause severe and sometimes fatal liver damage, often with no symptoms at all for the first day. It can cause vomiting, severe drowsiness, a racing heart and, with codeine, dangerously slow breathing. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Ushnol Sinus are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Older antihistamines cause marked drowsiness — do not drive or operate machinery until you know how this affects you. Tell your doctor promptly about any change in mood, sleep, agitation or unusual thoughts while taking montelukast; this is uncommon but recognised. This relieves the symptoms of an allergy; it does not treat the cause, and it is not a treatment for an acute asthma attack. Seek emergency care for swelling of the lips, tongue or throat, or difficulty breathing. Never exceed the daily maximum printed on the pack. Paracetamol overdose damages the liver, and the damage can be silent for a day or two before it becomes serious. Check every other medicine you are taking. Paracetamol is in a very large number of cold, flu and pain combinations, and the doses add together. If you drink alcohol regularly, or have liver disease, ask your doctor what daily limit is safe for you. See a doctor if fever lasts more than three days, or pain more than five. See a doctor if a cough lasts more than a week, or comes with fever, breathlessness, chest pain or blood in the sputum. Do not give cough and cold preparations to young children except on a doctor's advice. Do not combine two cough preparations — they frequently contain the same ingredients, and the doses add up. Preparations containing codeine can cause dependence and must be used only for the period your doctor specifies.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. The sedating antihistamines are not suitable for very young children, or for people with glaucoma or an enlarged prostate, without medical advice. Not for people with severe liver disease, except under medical supervision. Codeine-containing preparations are not for children, or for anyone with breathing difficulty.
Alcohol, sleeping tablets and other sedating medicines add to the drowsiness. Tell your doctor about all cold and cough preparations — many already contain an antihistamine. Regular alcohol use increases the risk of liver injury. Tell your doctor if you are on warfarin — regular high-dose paracetamol can affect it. Sedating ingredients add to the effect of alcohol and sleeping tablets. Decongestants such as phenylephrine and pseudoephedrine can raise blood pressure — tell your doctor if you are hypertensive.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Do not take Ushnol Sinus Tablet with other medicines containing paracetamol (commonly found in cold or fever medicines) unless advised by your doctor. Ushnol Sinus Tablet may cause dizziness or drowsiness, so avoid driving or operating machinery until you know how it affects you. Avoid alcohol or other sedating medicines while taking Ushnol Sinus Tablet, as they may increase sleepiness. Dry mouth or constipation may occur; maintaining hydration and adequate fiber intake may help. Inform your doctor if you have high blood pressure, heart disease, thyroid disorders, glaucoma, or prostate enlargement before using Ushnol Sinus Tablet. Avoid combining Ushnol Sinus Tablet with other decongestants or cough medicines unless your doctor advises you to. Consult your doctor if you experience palpitations, severe headache, or unusual restlessness. Use supportive measures such as warm fluids, saline gargles, or steam inhalation if suitable to help relieve symptoms. Consult your doctor if fever persists for more than a couple of days or if cold symptoms last longer than 5–7 days or worsen.
