Thioguanine Information

Thioguanine (thye'' oh gwah' neen) Tabloid® 2-Amino-6-mercaptopurine 6-TG 6-Thioguanine

Thioguanine is used to treat acute myeloid leukemia (AML; a type of cancer that begins in the white blood cells). Thioguanine is in a class of medications known as purine analogs. It works by slowing or stopping the growth of cancer cells in your body.

You should not become pregnant or breast-feed while you are receiving thioguanine. If you become pregnant while receiving thioguanine, call your doctor.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( for more information if you do not have access to a take-back program. It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body's response to thioguanine. Do not let anyone else take your medication.

You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
