i am having my first allergic reaction. have taken clarityn tablet. i have weals on my back and arm. no idea why. think it might be heat related as they popped up when i went from air conditioned car to open space.
something cold, ice pack, bag of peas might help to take some swelling down and ease the itching....whatever you do, don't scratch, you'll be on the itch-scratch cycle then, and that's a cycle you don't want to be on! also you could take the tops off and risk introducing infection, see your gp if no improvement with anti-histimines
have a shower to remove any irritant which might be on your skin. Then liberally smother yourself in hydrocortisone and take two paracetamol. It should help. If it doesn't I would seriously consider going to the Dr tomorrow.
hope you're feeling better today. Clarityn doesn't seem to do much for me but pirtion does. Medicines affect people in different ways so it's worth trying a different antihistamine if one doesn't help.
Lasonil cream is quite a good general purpose cream for bites etc, but sounds like you need an anti-histamine cream - hope GP can help. I think Piriton is best for allergies, if you have any - don't know if it clashes with Clarityn though.
