Warning: Tacrolimus should only be given under the supervision of a doctor who is experienced in treating people who have had an organ transplant and in prescribing medications that decrease the activity of the immune system.

Tacrolimus decreases the activity of your immune system. This may increase the risk that you will get a serious infection. If you experience any of the following symptoms, call your doctor immediately: sore throat; cough; fever; extreme tiredness; flu-like symptoms; warm, red, or painful skin; or other signs of infection.

When your immune system is not working normally, there may be a greater risk that you will develop cancer, especially lymphoma (a type of cancer that begins in the cells of the immune system). The longer you take tacrolimus or other medications that decrease the activity of the immune system, and the higher your doses of these medications, the more this risk may increase. If you experience any of the following symptoms of lymphoma, call your doctor immediately: swollen lymph nodes in the neck, armpits, or groin; weight loss; fever; night sweats; excessive tiredness or weakness; cough; trouble breathing; chest pain; or pain, swelling, or fullness in the stomach area.
