Safely Buy Lanvis ( Thioguanine ) from Canada Prescriptions Plus.

Indications

Lanvis is a medication that contains the active ingredient tioguanine. It belongs to a group of medicines called cytotoxics or chemotherapeutic agents.

Lanvis is used in the treatment of certain types of cancer, particularly blood cancers such as leukemia and in the treatment of chronic inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis.

Tioguanine, the active ingredient in Lanvis, works by interfering with the growth and replication of cancer cells. It is classified as a cytostatic agent, meaning it inhibits the division and reproduction of cells. This can help to slow down or stop the growth of cancer cells.

Use and Dosage

The recommended dose of thioguanine varies according to the specific condition being treated, the response to therapy, the other medications used, and the stage of the disease. The dose of thioguanine to be given also depends on body weight. A typical starting dose for adults is 2mg per kg of body weight per day taken once daily.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Take this medication exactly as prescribed by your doctor. It may cause nausea and vomiting, but you should continue to take it, even if you start to feel ill. Do not stop taking thioguanine without talking to your doctor. If you vomit shortly after taking it, contact your doctor for instructions on whether to take more medication or not. If you miss a dose, skip the missed dose, and go back to your regular dosing schedule. Do not take a double dose to make up for a missed one. If you miss more than 2 doses of thioguanine, contact your doctor.

Cautions

• Before you begin using 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 breastfeeding, and any other significant facts about your health. These factors may affect how you should use this medication.
• Anemia: Thioguanine may cause low levels of red blood cells. If you experience symptoms of reduced red blood cell count (anemia) such as shortness of breath, feeling unusually tired, or pale skin, contact your doctor as soon as possible.
• Blood clotting: This medication can reduce the number of platelet cells in the blood. Platelets help the blood to clot, and a shortage could make you bleed more easily. Tell your doctor of any signs that your blood is not clotting as quickly as usual. Such symptoms may include black and tarry stools, blood in the urine, easy bruising, or cuts that will not stop bleeding.
• Infection: As well as killing cancer cells, this medication can reduce the number of cells that fight infection in the body (white blood cells). Avoid contact with people with contagious infections and tell your doctor if you notice signs of an infection, such as fever or chills.
• Liver function: Thioguanine can reduce liver function and can cause liver damage. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor will order blood tests for your liver function regularly while you are taking this medication.
• 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.
• Pregnancy: There is a possibility of birth defects if either the man or woman is using thioguanine at the time of conception. Also, it may harm the baby if used during pregnancy. Effective birth control should be practiced while using this medication.
• This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
• Breast-feeding: It is not known whether thioguanine passes into breast milk. Because of the risks associated with this medication, a decision should be made, to stop breastfeeding or to stop the medication, taking into account the importance of the medication to the mother.
