Moderate
Cyclosporine (Neoral, Sandimmune)

The body breaks down cyclosporine (Neoral, Sandimmune) to get rid of it. Oregon grape might decrease how fast the body breaks down cyclosporine (Neoral, Sandimmune). This might cause there to be too much cyclosporine (Neoral, Sandimmune) in the body and potentially cause side effects.

Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates)

Some medications are changed and broken down by the liver. Oregon grape might decrease how quickly the liver breaks down some medications. Taking Oregon grape along with some medications that are broken down by the liver can increase the effects and side effects of some medications. Before taking Oregon grape, talk to your healthcare provider if you are taking any medications that are changed by the liver.Some medications changed by the liver include cyclosporine (Neoral, Sandimmune), lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and many others.
