Can I take Azathioprine and Diltiazem together?

Why this happens

Diltiazem can slow down the liver's ability to process certain medications. This can lead to higher levels of azathioprine (and its active components) staying in your bloodstream for longer than intended.

You can usually take these medicines together, but your doctor should monitor you more closely. You will likely need more frequent blood tests to check your blood cell counts (FBC) and liver function. If you develop a fever, sore throat, unexplained bruising, or feel unusually tired, contact your doctor immediately.
