I checked out an eqivalency chart that puts oral hydromorphone at 4 times the potency (mg for mg) of oral morphine sulphate. 180 mg of morphine sulphate is the equivalent of 45 mg hydromorphone. Other calculators use a ratio of 5 to 1 which would put you at 36 mg of hydromorphone

Note, the same first calculator has this to say: "Tips and Warnings When Converting TO this Opioid
Hydromorphone (Oral)
Extreme caution should be exercised when replacing morphine with hydromorphone. Hydormorphone is considerably more potent than morphine (10 mg injectable morphine = 1.5 mg hydromorphone), which has been fatal because of miscalculation and/or decimal point errors."

BTW, my mother suffers from MS and Fibromyalgia, I look after her, the MS is on hold, due to that in early stages she was administered Interferon once a week.
