I personally would say not. I don't think its necessary. It doesn't take away from the pain of the injection. And its best to see what side effects there are before giving panadol than after iykwim?

ETA: Just to clarify what i mean is i would rather wait and see what side effects their were (if any as most times there isn't) rather than have panadol possibly mask them.
