Help please? what is the equivalent of morphine to hydrocodone?

Depends: On many factors, including whether morphine is given by injection or by mouth, or whether in a long-acting or immediate-release short-acting form. In general, by mouth they are equipotent - 5 mg hydrocodone is equivalent to 5 mg morphine. If given by injection, it is about 1.7 mg morphine (about 3 times more potent) to 5 mg. Also depends onhow well liver and kidneys are working in some cases.
