Before taking thioguanine,
- tell your doctor and pharmacist if you are allergic to thioguanine, any other medications, or any of the ingredients in thioguanine tablets. Ask your pharmacist for a list of the ingredients.
- tell your doctor if you have already taken thioguanine or mercaptopurine to treat your cancer. Your doctor may tell you not to take thioguanine if either of these medications did not work well against your cancer in the past.
- tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: aminosalicylates such as mesalamine (Apriso, Asacol, Pentasa, others), olsalazine (Dipentum), and sulfasalazine (Azulfidine). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Also tell your doctor and pharmacist about all the medications you are taking so they can check whether any of your medications may increase the risk that you will develop liver damage during your treatment with thioguanine.
- tell your doctor if you have or have ever had liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. You should not become pregnant or breast-feed while you are receiving thioguanine. If you become pregnant while receiving thioguanine, call your doctor. Thioguanine may harm the fetus.
- do not have any vaccinations without talking to your doctor.
- you should know that the risk that you will develop serious side effects of thioguanine may be higher if you have a genetic (inherited) risk factor. Your doctor may order tests before or during your treatment to see if you have this risk factor.
