You never know when you’re going to be in an emergency - and the contents of your home first aid kit could be a life-saver.

As Alan Weir, head of clinical services at St John Ambulance says: “A well-stocked first-aid kit is essential to have at home and in the car – you never know when you might need it.”

But there’s more to it than popping a few plasters and some antiseptic cream in your medicine cupboard and letting them fester until they’re no longer usable.

Lloyds Pharmacy pharmacist Samantha Preston says: “A good first aid kit should include plasters, antiseptic wipes, clean dressings, microporous tape, gloves and bandages.

"Being the person that has to give first aid can be daunting, but having a well-stocked first aid kit and a bit of knowledge can make such a difference exactly when it counts.”

“Keep the kit somewhere dry and make sure your whole family knows where it is in case of an emergency,” adds Alan. “Make sure you check your first aid kit regularly, and replace any supplies that are running low or out of date.

“It’s important to know what you’re doing with your equipment too, so we suggest keeping a copy of the first aid manual with your kit, or you can download the St John Ambulance first aid app.”
