Can you take tramadol and Percocet?

I can't speak for paracetomol, but I use tramoldol and aspirin together with great success for Back pain.

My neurologist assured me that combining them was irrelevant because their actions were distinct, and no synergistic effects have been observed.

I suggest being wary of tramodol for long term use. Some person experience very unpleasant withdrawal despite the product literature claims.
