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. Menthol flavour, 150ml — a cooling hit with every dose.
Why menthol
For some people a chesty cough needs to feel treated as well as be treated. The menthol oral solution gives the same maximum-strength guaifenesin with a cooling vapour that opens the airways as it goes down — the bracing option for a stuffy, congested head and chest.
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.
Menthol or honey and lemon?
Same guaifenesin strength in both. Menthol gives a cooling, airway-opening feel; honey and lemon is smoother and sweeter. Pure preference.
