When to take anti histamine

[Maggsie]

Hi All, and Happy New Year.

I've recently started on Tocilizumab and I've noticed that I get a slight reaction the day after (tiny very itchy blisters on hands). The rheumy dept gave me a course of Piriton tabs when I did my first injection in case of any reaction. My question is, do I take 1 with the injection or wait til next day when the itching starts?

Anyone taking anti histamines with RD drugs?

I’d ask your rheumy/nurse or, failing that your pharmacist as they are qualified to advise you 😊
