prickly heat

You can buy some 1% hydrocortisone cream which will help. Boots sell it by the name of Dermacare.

You're best to use a plain moisturiser first, then apply the hydrocortisone cream very sparingly. (The leaflet in the box will explain how much).

This was advice from a dermatologist years ago, it creates a pathway so the hydrocortisone is better absorbed rather than sitting on the skin surface.

You can use it for up to 7 days then take a break for four days.

Ask your pharmacist for Chlorphenamine.

I had this a couple of weeks ago, thought it was a reaction to a new IV drug treatment which can cause hives but evidently it was just heat rash. The tablets were inexpensive and worked quickly but did make me a little drowsy.

Eurax cream, which is crotamiton, relives the itching and is a fall back if you need to drive or operate machinery so can't take anything that would makes you drowsy.

Obviously, check for any contraindications with any other meds you take.
