Great if you've got a cold, feeling the symptoms of flu, etc. 500mg Paracetamol, 25 mg caffeine and 5 mg phenylephrine hydrochloride (decongestant). Same ingredients as some of the other Beechams products, and at £1.00 for 14 caplets, they're an absolute bargain.
In a handy wallet-style pack that means you can rip out two caplets at a time so you've got some handy wherever you are!
Tesco currently selling for £2.39 (normally £3.39), Boots around £3.60ish.
