What should I discuss with my healthcare provider before taking thioguanine (Tabloid)?
You should not use thioguanine if you are allergic to it, or if you have ever used thioguanine or mercaptopurine (Purinethol) and they were not effective in treating your condition.
To make sure you can safely take thioguanine, tell your doctor if you have any of these other conditions:
It is not known whether thioguanine passes into breast milk or if it could harm a nursing baby. You should not breast-feed while taking thioguanine.
How should I take thioguanine (Tabloid)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Thioguanine can lower blood cells that help your body fight infections. Your blood cells, kidney function, and liver function may need to be tested often. Your cancer treatments may be delayed based on the results of these tests. Do not miss any follow up visits to your doctor for blood or urine tests.
Store at room temperature away from moisture and heat.
