That's not unusual.

Make sure he's drinking water. Offer it with an eyedropper if
needed, but make sure he doesn't get dehydrated.

Yes, do keep an eye on it.
He will probably be off sorts tonight yet, and be interested in
things tomorrow, but a little slow yet. There isn't any real
way that painkiller that can be administered to a gerbil;
(size and other considerations) for post surgery discomfort,
but it will quickly pass.
