Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take Revlimid (Lenalidomide).
Bleeding: Revlimid (Lenalidomide) may cause a reduced number of platelets in the blood, which can make it difficult to stop cuts from bleeding. If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.
Blood Clots: Revlimid (Lenalidomide) increases the risk of developing blood clots in the legs and lungs. If you experience sudden shortness of breath, blurred vision, difficulty speaking, chest pain, arm or leg pain, and swelling, contact your doctor immediately.
Blood donation: Do not give blood during and for 4 weeks after your treatment with Revlimid (Lenalidomide). If a pregnant woman received your donated blood, her baby could be exposed to Revlimid (Lenalidomide) and might be born with birth defects.
Cardiovascular effects: Revlimid (Lenalidomide) may have effects on the heart and circulatory (blood vessels) system, including Heart Attack, stroke, and changes in blood pressure. If you have heart disease, high blood pressure, and other diseases of the heart and blood system, discuss with your doctor how Revlimid (Lenalidomide) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Revlimid (Lenalidomide), and whether any special monitoring is needed.
Diabetes: Revlimid (Lenalidomide) may cause an increase in blood sugar levels and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using Revlimid (Lenalidomide).
If you have diabetes or are at risk for developing diabetes, discuss with your doctor how Revlimid (Lenalidomide) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Revlimid (Lenalidomide), and whether any special monitoring is needed.
Drowsiness/reduced alertness: Revlimid (Lenalidomide) is not expected to make you drowsy or impair your ability to drive or use machinery. However, it may make some people feel weak. Do not drive or use machinery if you feel weak.
Infections: When Revlimid (Lenalidomide) decreases the number of cells that fight infection in the body (white blood cells), it increases the risk of infections. It may also cause infections such as herpes zoster or hepatitis B to flare up. If you notice any signs of an infection, such as fever or chills, severe diarrhea, shortness of breath, prolonged dizziness, headache, stiff neck, weight loss, or listlessness, contact your doctor immediately.
Kidney function: Kidney Disease or reduced kidney function may cause Revlimid (Lenalidomide) to build up in the body, causing side effects. If you have kidney problems, discuss with your doctor how Revlimid (Lenalidomide) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Revlimid (Lenalidomide), and whether any special monitoring is needed.
Lactose intolerance: Revlimid (Lenalidomide) contains lactose. If you have galactose intolerance (galactosemia, glucose-galactose malabsorption, or Lapp lactase deficiency) you should not take Revlimid (Lenalidomide). Talk to your doctor about other alternatives.
Liver function: Revlimid (Lenalidomide) has been reported to cause a decrease in liver function including fatal liver failure. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately. Your doctor may want to test your liver function regularly with blood tests while you are taking Revlimid (Lenalidomide).
Progressive multifocal leukoencephalopathy (PML): There have been reports of PML after using Revlimid (Lenalidomide). PML is a rare disorder that causes nerve damage in the brain. If you experience memory loss, vision changes, trouble thinking, personality changes or difficulty walking, contact your doctor immediately.
Second cancers: A small number of patients with multiple myeloma have reported second cancers such as skin cancers or other invasive cancers. Talk to your health care provider if you have any concerns.
Thyroid problems: Both hypothyroidism (low thyroid) and Hyperthyroidism (overactive thyroid) have been reported with Revlimid (Lenalidomide). If you have thyroid problems, discuss with your doctor how Revlimid (Lenalidomide) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Revlimid (Lenalidomide), and whether any special monitoring is needed.
Tumour lysis syndrome: Revlimid (Lenalidomide), like many other cancer medications, causes many cancer cells to be suddenly killed when treatment is first started. This can overwhelm the body with waste products from the cells. As a result, the body may not be able to keep up with getting rid of all the waste. When this happens, you may experience nausea, shortness of breath, or notice cloudy urine or joint pain. This is called tumour lysis syndrome. Your doctor may prescribe some medications to help your body get rid of the waste products. Make sure you understand how to use these medications and report any of these signs or symptoms to your doctor immediately.
Pregnancy: Revlimid (Lenalidomide) must not be used during pregnancy because of the potential for it to cause serious birth defects. Women who take Revlimid (Lenalidomide) must use 2 methods of birth control for 4 weeks before starting treatment with Revlimid (Lenalidomide), during treatment with Revlimid (Lenalidomide), and for at least 4 weeks after treatment has stopped.
Your doctor will ask you to do 2 pregnancy tests before starting Revlimid (Lenalidomide) and regularly during treatment with Revlimid (Lenalidomide). If you become pregnant while taking Revlimid (Lenalidomide), contact your doctor immediately.

Breast-feeding: The safety of taking Revlimid (Lenalidomide) while breast-feeding has not been determined. It is not known if Revlimid (Lenalidomide) passes into breast milk.

Seniors: People over the age of 65 who take Revlimid (Lenalidomide) may be at increased risk of developing side effects associated with the heart and kidneys. Your doctor may want to monitor you more closely while you are taking Revlimid (Lenalidomide).
