Who is this for?

What is this drug?

This is a combination medicine containing three active ingredients — pseudoephedrine (a decongestant that opens up blocked nose), chlorphenamine (an antihistamine that stops sneezing and runny nose), and dextromethorphan (a cough suppressant that calms dry cough) — working together to relieve cold and flu symptoms.

Cold & Flu Remedies Cough & Cold Allergies

How it works

Activates α-adrenergic receptors to cause vasoconstriction of nasal blood vessels, reducing congestion; blocks H1 histamine receptors to suppress allergic symptoms; and inhibits the cough reflex centre in the medulla oblongata by depressing the central nervous system.

How to take this drug

For adults, typically take 1-2 tablets or 10ml of syrup every 6-8 hours as needed. You can take it with or without food. Do not exceed 4 doses in 24 hours. This medicine can make you drowsy, so avoid taking it when you need to drive or operate machines.

What if I Miss a Dose?

Since this medicine is taken only when you have symptoms, there is no strict schedule. If you miss a dose, take it when you remember. If it is almost time for your next dose, skip the missed one. Never double up to catch up.

What to watch out for

Buy only from licensed pharmacies — avoid roadside sellers or open market drugs, as fake cold medicines are common in Nigeria. Do not combine with other cold and flu medicines like Actifed, Benylin, or similar products, as you may accidentally overdose on the same ingredient. This medicine treats symptoms only — if your cold or cough lasts more than 7 days or you develop fever, see a doctor.

Common Side Effects

Feeling sleepy or drowsy
dry mouth
mild dizziness
slight headache
feeling restless or unable to sleep (especially from the pseudoephedrine component)

Serious Side Effects

Fast or irregular heartbeat — go to the hospital immediately. Difficulty breathing or swelling of the face
lips
or throat (this could be a serious allergic reaction). Severe dizziness or confusion that does not go away.

Drug Interactions

Do not drink alcohol while taking this medicine as it increases drowsiness and dizziness significantly. Do not take it together with MAO inhibitor drugs or other cold/flu medicines containing similar ingredients, as this can cause dangerous side effects. Avoid taking with blood pressure medications, as pseudoephedrine can raise your blood pressure.
