I was stuck sitting next to a cat owner today (they don't know they smell) and my allergies are haywire. Itchy eyes, runny nose etc. I've tried eye drops but they're making my eyes worse. I have nothing that would work short term for my nose. My GP says because I'm only 5+5 I'm not allowed to take antihistamines until I'm at least 9 weeks then I can take piriton.
What's the risk of taking piriton this early? I'm not wheezing thankfully so could survive with swollen eyes and a snottery beak for the night and hope it goes by morning but it's miserable.
