How Sinarest Syrup works

Sinarest New Tablet is a combination of three medicines: Chlorpheniramine, paracetamol and phenylephrine which relieves common cold symptoms. Chlorpheniramine is an antiallergic which relieves allergy symptoms like 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 which narrows the small blood vessels providing relief from congestion or stuffiness in the nose.

How to take Sinarest Syrup

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. Sinarest New Tablet may be taken with or without food, but it is better to take it at a fixed time.<br/>Take it with food if stomach upset occurs.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine 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. It can cause severe drowsiness, a fast heartbeat, confusion and, in children, agitation and fits. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Sinarest Syrup

Most side effects of Sinarest are mild and settle as the body adjusts. Reported side effects include:

  • Nausea Vomiting Allergic reaction Sleepiness Headache

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.

Warnings and precautions

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. 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.

Do not take Sinarest if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with severe liver disease, except under medical supervision. Codeine-containing preparations are not for children, or for anyone with breathing difficulty. The sedating antihistamines are not suitable for very young children, or for people with glaucoma or an enlarged prostate, without medical advice.

Interactions with other medicines

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. 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.

How to store Sinarest Syrup

Store below 30°C, away from direct sunlight. Do not freeze. Once opened, use it within the period printed on the pack. Keep out of the reach of children.
