Mycophenolate

Medication Information Leaflet

What is this medication for?

Mycophenolate belongs to a group of medications known as immunosuppressive agents. It is used to prevent your body from rejecting a transplanted organ.

This medication can also be used to treat autoimmune diseases, where the body’s natural defence system attacks its own body cells.

How should I take/use this medication?

Mycophenolate mofetil: Take this medication half to one hour before food.

Mycophenolate sodium EC tablet: May be taken with or without food.

Do not chew, crush, or open the capsules/tablets. The tablets/capsules should be swallowed as a whole.

What should I do if I forget to take/use this medication?

If you forget to take a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose. Then take your next dose at the usual time.

Do not take two doses to make up for the missed dose.

What precautions should I take?

Inform your healthcare professional if you:
Are allergic to mycophenolate sodium, mycophenolate mofetil, or to any of the ingredients.
Have cancer, kidney disease, liver disease, stomach/intestinal problems (e.g., gastric ulcers), diabetes, high blood pressure, high cholesterol, or symptoms of infection.
Are going for immunizations (vaccinations) as mycophenolate may either increase the chance of an infection or make the vaccine less effective.
Are pregnant, planning to have a child, or breastfeeding.

Mycophenolate has been reported to be able to cause harm to the foetus when taken during pregnancy (miscarriages and birth defects).
Mycophenolate may decrease the effectiveness of birth control pills. Therefore, it is important to use an additional form of birth control (barrier methods e.g., condoms) to prevent pregnancy. Inform your doctor immediately if you think you are pregnant or if you have missed your menstrual period.
Women of childbearing age should have a negative pregnancy test before starting this medication. Also, it is important to use two reliable forms of birth control (unless the contraceptive method is intrauterine device, tubal sterilisation, or vasectomy) before beginning treatment and continue for at least 6 weeks after mycophenolate is stopped.
Sexually active male patients and their female partners should use birth control during treatment of the male patient and for at least 90 days after the last dose.
Breast-feeding is not recommended during and for at least 6 weeks after stopping mycophenolate treatment as mycophenolate may enter into the breastmilk.

Do not donate blood during treatment with mycophenolate and for at least 6 weeks after stopping treatment.
Avoid prolonged sun exposure. Use sunscreen and wear protective clothing when you are outdoor.
