Cellcept (Mycophenolate mofetil Oral)

Generic name: Mycophenolate Mofetil
Drug class: Selective immunosuppressants

Usage of Cellcept (Mycophenolate mofetil Oral)

Mycophenolate belongs to a group of medicines known as immunosuppressive agents. It is used with other medicines (eg, cyclosporine, steroid medicine) to lower the body's natural immunity in patients who receive organ transplants (eg, kidney, heart, or liver).

When a patient receives an organ transplant, the body's white blood cells will try to get rid of (reject) the transplanted organ. Mycophenolate prevents the white blood cells from rejecting the transplanted organ.

This medicine is available only with your doctor's prescription.

Before taking Cellcept (Mycophenolate mofetil Oral)

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of mycophenolate capsules, suspension, or tablets in children receiving kidney transplants. However, safety and efficacy have not been established in infants younger than 3 months of age.

Appropriate studies have not been performed on the relationship of age to the effects of mycophenolate capsules, suspension, or tabletsin children receiving heart or liver transplants. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of mycophenolate delayed-release tablets in children receiving kidney transplants. However, safety and efficacy have not been established in children younger than 5 years of age.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of mycophenolate in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving mycophenolate.

Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.

Using this medicine while you are pregnant can harm your unborn baby or cause a miscarriage during the first 3 months. If you are a woman who can bear children, your doctor may give you a pregnancy test before you start using this medicine to make sure you are not pregnant. Your birth control pills may not work as well while you are using this medicine. You must use two forms of birth control together for 1 month before starting this medicine, for the entire time that you are being treated, and for 6 weeks after you receive your last dose of this medicine. Use birth control pills together with another form of birth control, including a condom, diaphragm, or contraceptive foam or jelly. Male patients with female partners should use an effective form of birth control during treatment and for at least 90 days after the last dose. If you think you have become pregnant while using the medicine, tell your doctor right away.

Do not donate sperm during treatment and for at least 90 days after the last dose.

Using 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 30 on a regular basis when you are outdoors. Wear protective clothing and hats and stay out of direct sunlight, especially between the hours of 10 am. and 3 pm. Avoid sunlamps and tanning beds.

Mycophenolate can temporarily lower the number of white blood cells in your blood, which increases the chance of getting an infection. If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you have a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

Mycophenolate may cause 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.

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 have vision changes, loss of coordination, clumsiness, memory loss, difficulty speaking or understanding what others say, and weakness in the legs.

This medicine may increase your risk of developing rare and serious virus infections, including shingles, herpes, cytomegalovirus (CMV) infection, polyomavirus associated nephropathy (PVAN), BK virus-associated nephropathy (BKVAN), or SARS-CoV-2 (COVID-19) infection. The BK virus may affect how your kidneys work and cause a transplanted kidney to fail. Check with your doctor right away if you have 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 cause reactivation of hepatitis B or C infection. Check with your doctor right away if you have dark-colored urine or pale stools, nausea, vomiting, loss of appetite, pain in your upper stomach, or yellow skin or eyes.

Check with your doctor right away if you have difficulty in moving, fever, muscle pain or stiffness, or pain, swelling, or redness in the joints. These may be symptoms of acute inflammatory (swelling) syndrome.

While you are using mycophenolate, and after you stop, do not have any immunizations (vaccinations) without your doctor's approval. Mycophenolate will lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent.

This medicine may cause serious stomach or bowel problems (eg, ulcers, bleeding). Check with your doctor right away if you have black, tarry stools, constipation, diarrhea, heartburn, indigestion, nausea, stomach pain, cramping, or burning, trouble breathing, or vomiting of blood or material that looks like coffee grounds.

This medicine may inhibit the ability to drive and use machines. Avoid driving or using machines if confusion, dizziness, fainting, lightheadedness, sleepiness, or trembling or shaking of the hands or feet occur during treatment.

Do not stop taking this medicine without checking first with your doctor. Doing so may cause rejection of your transplanted organ. Your doctor will decide how long you should take this medicine.

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 or vitamin supplements.
