Pharmacists are the people who should know. Its what they do.  You might try calling one of the large pharmacy chains, like Rite Aid, which probably has a 1-800 number.

An IU is a international standard of an agreed upon biological effect.  Every substance is different, and many drugs dont have an IU conversion because their potency differs with how they are prepared.

1 IU of insulin is 45.5 ug, 1 IU of Vitamin A is 0.3 ug, 1 IU of Vitamin D is 25 ng. So you see how the conversion differs between various drugs and vitamins.

You could also try contacting the manufacture of the drug. They may have a website with information.
