Buy Beechams All In One - 16 Tablets 

Beechams All In One are designed to provide you with short-term relief from the symptoms of cold and flu with a chesty cough.


How Beechams All In One works

Beechams All In One contains three active ingredients. The first ingredient is paracetamol, a painkiller that helps to reduce your temperature when you have a fever.

It also contains guaifenesin, an expectorant which loosens phlegm and relieves a chesty cough.

Finally, the decongestant phenylephrine hydrochloride unblocks your nose and sinuses to help you breathe more easily. 



Always take Beechams All In One exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Fill the measuring cup to the 20ml mark. Take one 20ml dose every 4 hours. 

Do not take the dose more frequently than 4 hours. 

Do not take more than 4 doses in a 24-hour period. 

Do not take it for more than 5 days in a row without consulting your doctor or pharmacist.
