No, it is not stronger than hydro..... It is Ultram (Tramadol) compounded with Tylenol. It is actually even weaker than Ultram because it contains less active ingredient (tramadol) - It is more close, strength-wise, to codeine - although I find that is not even that strong... It seems weaker than codeine for me, and doesn't do a thing to kill pain. I have found the only thing it is good for is to rotate with my hydro/apap pain meds, because it WILL help with not going into w/d from opioid pain meds - but it is a terrible pain killer... I have back problems, and even at 100-150mg's Tramadol, I get NO relief from it, NONE..... Ask for something better.
