Lanvis Warnings

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 breast-feeding, and any other significant facts about your health.

Liver function: Lanvis (Thioguanine) can reduce liver function and can cause liver damage. If you have liver problems, discuss with your doctor how Lanvis (Thioguanine) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Lanvis (Thioguanine), and whether any special monitoring is needed. Your doctor will order blood tests for your liver function regularly while you are taking Lanvis (Thioguanine).

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 defect if either the man or woman is using Lanvis (Thioguanine) at the time of conception. As well, it may harm the baby if used during pregnancy. Effective birth control should be practiced while using Lanvis (Thioguanine).
