It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

This medicine may increase your risk of getting skin cancer or cancer of the lymph system (lymphoma). Talk to your doctor if you have concerns about this risk.

Use sunscreen or sunblock lotions with a sun protection factor (SPF) of at least 15 on a regular basis when you are outdoors. Wear protective clothing and hats, and stay out of direct sunlight between the hours of 10 am and 3 pm. Avoid sunlamps and tanning beds.

This medicine may increase your risk of developing infections. Avoid being near people who are sick while you are using this medicine. Wash your hands often. Tell your doctor if you have any kind of infection before you start using this medicine. Tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.

While you are being treated with tacrolimus, and after you stop treatment with it, do not have any immunizations (vaccines) without your doctor's approval. Tacrolimus may lower your body's resistance and the vaccine may not work as well or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.

This medicine may increase your risk for developing a rare and serious virus infection with the BK polyoma virus. This virus may affect how your kidneys work and cause a transplanted kidney to fail. Check with your doctor right away if you are having more than one of these symptoms: bloody urine, a decreased frequency or amount of urine, increased thirst, loss of appetite, lower back or side pain, nausea, swelling of the face, fingers, or lower legs, trouble breathing, unusual tiredness or weakness, vomiting, or weight gain.

This medicine may increase your risk of developing a serious and rare brain infection called progressive multifocal leukoencephalopathy (PML). Check with your doctor right away if you are having more than one of these symptoms: vision changes, loss of coordination, clumsiness, confusion, memory loss, difficulty speaking or understanding what others say, or weakness in the legs.

This medicine may increase your risk of a stomach problem called gastrointestinal perforation. Talk to your doctor if you have concerns about this risk.

This medicine may cause serious nervous system problems. Tell your doctor right away if you have the following symptoms while using this medicine: blurred vision, dizziness, headache, mental changes, seizures, high blood pressure, or a fast heartbeat.

Hyperkalemia (high potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have abdominal or stomach pain, confusion, difficulty with breathing, an irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, or weakness or heaviness of the legs.

Tacrolimus may cause a condition called pure red cell aplasia (PRCA). This is a very rare condition where the body no longer makes red blood cells and the patient has severe anemia. Check with your doctor right away if you have a fever and sore throat, pale skin, unusual bleeding or bruising, or unusual tiredness or weakness.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
