woken with a rash, what can I take?

[TheNinjaGooseIsOnAMission]

I was a bit itchy when I went to bed last night but have woken up with a rash on my legs, tummy and upper arms I'm thinking probably allergic reaction or possibly heat rash as feel fine otherwise but have no idea what to take or put on it as not had this before. Any ideas?

an anti-histamine?

thanks seona, not taken any before, are any particular ones good, would need non drowsy?

loratadine and cetirizine are non-drowsy - you can get generic ones or branded ones at the supermarket/chemist, etc

thanks will have a look and try one
