Who is this for?
This is a combination cold and flu medicine that contains paracetamol (to reduce fever and pain), phenylephrine (to unblock your stuffy nose), chlorphenamine (to stop sneezing and runny nose), and menthol (to soothe your throat and help you breathe easier).
Inhibits COX-1 and COX-2 enzymes, reducing prostaglandin synthesis to alleviate pain, fever, and inflammation; activates α1-adrenergic receptors causing nasal vasoconstriction to relieve congestion; blocks H1 histamine receptors to suppress allergic symptoms including sneezing, rhinorrhoea, and lacrimation; soothes irritated mucous membranes through topical cooling action.

Adults should take 1 to 2 tablets every 4 to 6 hours as needed, but do not take more than 8 tablets in 24 hours. You can take it with or without food, but taking it with a little food can help if it upsets your stomach. Swallow with a full glass of water.
Since this medicine is taken only when you have symptoms, there is no strict schedule. If you forget a dose, just take it when you remember, but make sure you do not take more than the maximum daily dose.
Do not combine this with other paracetamol products like Boska or Hedex — too much paracetamol can seriously damage your liver. This medicine can make you very drowsy, so avoid driving okada, keke, or car after taking it. Buy only from licensed pharmacies, not roadside sellers, and always check the expiry date on the pack.
Do not drink alcohol while taking this medicine as it can make you very drowsy and can increase the risk of liver damage. Avoid taking other paracetamol-containing medicines (like Procold, Combiflam, or another cold medicine) at the same time to prevent overdose. If you are taking blood pressure medications, talk to your doctor first because phenylephrine can raise your blood pressure.
