Product overview
About Benylin Mucus Cough Max
Benylin's maximum-strength expectorant: guaifenesin at 100mg per 5ml, the highest over-the-counter strength, to thin and loosen the stubborn mucus behind a heavy chesty cough and deliver deep, penetrating relief. Honey and lemon flavour in the big 300ml bottle.
Who the 300ml suits
When the whole house is coughing, 150ml goes in days. The 300ml keeps a family dosed through the week and costs less per spoonful — the sensible bottle for winter's second and third colds too, as long as it's used within the date once opened.
How to take
Take by the measuring cup as directed on the pack, spacing doses through the day, with plenty of fluids to help the mucus move. Check the label for the minimum age.
Good to know
Don't combine with a dry-cough suppressant, and ask a pharmacist first with asthma or COPD. A cough beyond three weeks, or with blood, breathlessness or chest pain, needs a GP.

Frequently asked questions
What does “Max” mean?
Guaifenesin at 100mg per 5ml — the maximum over-the-counter strength — for heavier chesty coughs where the standard syrup isn't shifting enough.
Will it make me drowsy?
No — guaifenesin is a non-sedating expectorant, so it suits daytime use.
How long does an opened bottle last?
Check the label for the in-use period after opening and note the date on the box — the 300ml is meant for a household, not one person's whole winter.
