Moderate Interaction with Cyclosporine (Neoral, Sandimmune):
The organism splits cyclosporine (Neoral, Sandimmune) to remove it from the body. Oregon grape can lower the speed of splitting cyclosporine (Neoral, Sandimmune). This can be the reason of having too much cyclosporine (Neoral, Sandimmune) in the body and probably be the source of undesirable effects.
Moderate Interaction with Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates):
Some medications such as cyclosporine (Neoral, Sandimmune), lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and many others are metamorphosed and splitted by the liver. Oregon grape can enlarge the speed of splitting some medications by the liver. Simultaneous consumption of Oregon grape and listed medications can strengthen the efficacy as well as undesirable effects of some medications.
