Antihistamine: Antihistamines can still cause drowsiness even if it says, non-drowsy, especially loratadine. Paradoxical effects of hyperactivity can be a side effect of antihistamines, though it tends to happen mostly in the very young or old. If you took a decongestant with it, then that can also cause hyperactivity.
