Product overview
About Benylin Chesty Coughs Original
The Benylin that's been in the cupboard for generations: diphenhydramine with levomenthol in a thick, warming syrup that eases a chesty cough and the congestion behind it for up to eight hours, and helps you sleep through it. The Original is the pharmacy-only formula; the non-drowsy version is the one on the shelf. 150ml bottle, for adults and children over 12.
Original or non-drowsy
Benylin Chesty Coughs Non-Drowsy uses guaifenesin to loosen mucus for the daytime. The Original uses diphenhydramine, an antihistamine that dries the drip feeding the cough and sedates the cough reflex, with menthol to open the airways. It's the night-time choice, and the one for a cough that's exhausting you.
How to take
Adults and children over 12: 10ml four times a day, using the measuring cup, no more than 40ml in 24 hours. Not for under-12s. Don't take with any other diphenhydramine or cough and cold product. If the cough hasn't improved in a few days, see a pharmacist or GP.
Good to know
Causes drowsiness, so no driving or alcohol after a dose. Ask a pharmacist first with glaucoma, prostate or bladder problems, asthma or a long-term chest condition, or in pregnancy or breastfeeding. Pharmacist-reviewed before dispatch.

Frequently asked questions
What's the difference from Benylin Chesty Non-Drowsy?
Non-Drowsy uses guaifenesin to loosen mucus by day. Original uses diphenhydramine, which calms the cough and makes you drowsy — the one for night-time and pharmacy-only.
Can children take it?
Only from age 12. For younger children there's Benylin Children's Chesty Coughs (from 6) and Children's Night Coughs.
Can I take it with paracetamol?
Yes — it contains no painkiller. Don't take it with any other antihistamine, sleep aid or cough medicine.
