Is taking 5mg percocet 3mg lorazepram and Claritin Bad?

Answer 1

Only the Claritin D version can make your drowsy; If you're tolerant enough to Percocet, that low of a dose of Lorazepam shouldn't even phase you, and I'd be willing to bet you're taking it as an augment for the Percocet rather than as a relaxant.

The only thing is that Percocet, like most opiates, is a vasodilator, meaning it opens the blood vessels. Claritin, like most allergy meds, work by constricting blood vessels, so it may not work as well. You might consider something that works on a different mechanism, like Singulair. Though it's been primarily an Asthma drug for many years, they've found it works great for Allergies as well, and have recently begun marketing it as such. The difference is that it doesn't work like most allergy drugs like Claritin.
