Are you a clinician? See the clinical version of this page.

The short versionMycophenolate is an immune-calming medicine used for lupus, and it is a mainstay for lupus that affects the kidneys. It lowers the activity of the immune cells that drive inflammation, which helps control the disease and protect organs.
How you take it

Taken as capsules or tablets, usually twice a day. It is a strong medicine that must NOT be used in pregnancy, and reliable contraception is essential, because it can cause miscarriage and birth defects.

Tests while you take it

You will have regular blood tests, more often at first. Reliable contraception is required during treatment and for 6 weeks after stopping. Report signs of infection.

What to know

How it is used in lupus

Mycophenolate is used to bring lupus under control and to keep it settled, and it is one of the main choices when lupus affects the kidneys, sometimes together with another medicine.

Common side effects

The more common effects are stomach upset such as nausea or loose stools, which often settle or improve with a dose change. It can lower your blood counts and raise the chance of infections, which is why regular blood tests matter.

Tests and monitoring

You will have blood count tests when you start and about 2 weeks after any dose change, then regularly once your dose is steady. If you could become pregnant, you will have a pregnancy test before starting, again about 8 to 10 days later, and at later visits, because this medicine is not used in pregnancy.

Important cautions

Mycophenolate can harm a pregnancy and is generally stopped before trying to conceive, so reliable contraception is important while taking it. When someone is planning a pregnancy, azathioprine is often used instead. Your reviewed pregnancy guidance is on the separate pregnancy page.
