Benadryl under 2 years old?

[CasaBevron]

Ds (16 months) is a bit post-virally hivey/itchy at the moment after having hand foot and mouth a couple of weeks ago. His specialist has recommended a daily dose of cetirizine for the next week or so. He was prescribed it at 8 months but we have run out of the generic stuff that we were given by the pharmacy. Is Benadryl the same stuff? The box says not recommended for under two's . Can anyone advise please??

TIA

Would prition be any good? Its 12months+

Thanks BlackOutTheSun. I do have Piriton for him, but cetirizine is longer-acting and non-drowsy so only needs one small dose a day. He tends not to sleep very well on Piriton, I believe it makes a lot of kids hyper! The specialist assured us that there's no problem giving it daily for a few weeks, I just want to be sure I'm giving him the same thing.
