Uses for Jylamvo

Methotrexate tablet is used alone or with other medicines to treat different types of cancer, including breast, head and neck, lung, blood (for example, acute lymphoblastic leukemia or ALL), bone, lymph node (for example, mycosis fungoides, relapsed or refractory non-Hodgkin lymphoma), or uterus cancer. It is also used to treat rheumatoid arthritis, severe psoriasis (a skin disease), lupus, multiple sclerosis, and polyarticular juvenile idiopathic arthritis (pJIA).

Methotrexate oral solution is used with other medicines to treat acute lymphoblastic leukemia (ALL) or relapsed or refractory non-Hodgkin lymphoma. It is also used alone or with other medicines to treat mycosis fungoides. This medicine is also used to treat rheumatoid arthritis and severe psoriasis (a skin disease), and to help manage polyarticular juvenile idiopathic arthritis (pJIA) in children who have not responded well to other treatments.

Methotrexate is part of a group of medicines called antineoplastics (cancer medicines). It blocks an enzyme that cells need to survive. This slows down the growth of cancer cells, which are eventually destroyed by the body.

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

Precautions while using Jylamvo

It is very important for your doctor to check your progress regularly to ensure this medicine is working well and to look for any unwanted effects. You may need blood and urine tests to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. It may also cause birth defects if the father uses it when his partner becomes pregnant. If you are a woman who can get pregnant, your doctor may give you a pregnancy test before you start this medicine to ensure you are not pregnant. Female patients should use an effective form of birth control during treatment and for at least 3 or 6 months after the last dose. Male patients with female partners should also use effective birth control during treatment and for at least 3 months after the last dose. Tell your doctor immediately if you become pregnant while using this medicine.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical help. Contact your doctor right away if you experience a rash, itching, dizziness, fainting, fast heartbeat, trouble breathing or swallowing, or chest tightness while using this medicine.

Talk to your doctor before using this medicine if you plan to have children. Some men and women who use this medicine have become infertile (unable to have children).

Limit alcohol use while taking this medicine. Alcohol may increase the risk of liver problems.

Contact your doctor immediately if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellowing of the eyes or skin. These could be signs of a serious liver problem.

Methotrexate can reduce the number of white blood cells in your blood, which raises the risk of infections. It can also lower the number of platelets, which are needed for your blood to clot properly. If this happens, there are precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If possible, avoid contact with people who have infections. Contact your doctor right away if you think you might have an infection or if you develop a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Contact your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in urine or stools, or pinpoint red spots on your skin.
  • Be careful when using a regular toothbrush, dental floss, or toothpick. Your doctor, dentist, or nurse may suggest other ways to clean your teeth and gums. Check with your doctor before having any dental work done.
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else afterward.
  • Be cautious when using sharp objects such as safety razors or fingernail or toenail clippers to avoid cuts.
  • Avoid contact sports or other activities where bruising or injury could happen.

This medicine may cause stomach and bowel issues. Contact your doctor right away if you have stomach pain, black, tarry stools, constipation, diarrhea, loss of appetite, nausea, pain in the back of the throat or chest when swallowing, or vomiting blood or material that looks like coffee grounds.

Contact your doctor immediately if you have a cough, fever, or trouble breathing. These could be signs of serious lung or breathing problems (e.g., acute or chronic interstitial pneumonitis).

While you are being treated with methotrexate, and after stopping treatment, do not receive any immunizations (vaccines) without your doctor's approval. Methotrexate 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. Additionally, you should avoid contact with anyone in your household who receives live virus vaccines because they could pass the virus to you. Examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Stay away from them and do not spend a long time in the same room with them. If you have questions about this, talk to your doctor.

Serious skin reactions (e.g., toxic epidermal necrolysis, Stevens-Johnson syndrome, exfoliative dermatitis, skin necrosis, or erythema multiforme) can occur with this medicine. Contact your doctor immediately if you have blistering, peeling, or loosening of the skin, blue-green to black skin discoloration, cough, cracks in the skin, diarrhea, itching, joint or muscle pain, loss of heat from the body, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, fever or chills, or unusual tiredness or weakness while using this medicine.

This medicine may make your skin more sensitive to sunlight. Wear sunscreen, eye protection, and a hat. Do not use sunlamps or tanning beds.

Tell your doctor right away if you notice a change in how much or how often you urinate, rapid weight gain, swelling in the legs, ankles, or feet, or trouble breathing. These could be symptoms of a serious kidney problem.

This medicine may cause serious nerve issues. Contact your doctor immediately if you experience seizures, confusion, tingling or numbness in your hands, feet, or lips, trouble seeing, or headaches.

This medicine may increase your risk of other cancers, including blood or skin cancer. The risk for skin cancer may be higher if you take cyclosporine after receiving treatment with methotrexate for psoriasis.

This medicine may cause a serious reaction called tumor lysis syndrome. Your doctor may prescribe another medicine to help prevent this. Tell your doctor immediately if you notice changes in your urine amount, joint pain, stiffness, or swelling, lower back, side, or stomach pain, rapid weight gain, swelling of the feet or lower legs, or unusual tiredness or weakness.

Do not take other medicines unless your doctor has discussed them with you. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
