Although CellCept and Myfortic both contain forms of mycophenolate, they are not the same medication. The body handles these two forms of mycophenolate differently. In fact, the body breaks down mycophenolate mofetil and converts it into mycophenolate sodium.
Mycophenolate mofetil is approved to prevent organ rejection in people who have received a heart, kidney, or liver transplant, while mycophenolate sodium is only approved to prevent rejection in people who have received a kidney transplant. Both forms are used in combination with other medications.
Another difference is that mycophenolate sodium (Myfortic) comes as a specially coated, delayed-release tablet that bypasses the stomach and dissolves in the intestines. Mycophenolate mofetil is not delayed-release.
Mycophenolate sodium and mycophenolate mofetil are not interchangeable. Therefore, if you need to switch from one brand or type of mycophenolate to another, only do so under the supervision of your healthcare provider. If you happen to receive a mycophenolate product that looks unfamiliar to you, check with your pharmacist to make sure you received the correct drug.
