An Overview of Granisetron Transdermal Drug Interactions

Granisetron transdermal (Sancuso®) can potentially interact with a few other medications. Some of these medicines that might lead to interactions include:

Drug Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when granisetron transdermal is combined with any of the drugs listed above.
Ketoconazole (Nizoral)
Ketoconazole may decrease the ability of your liver to metabolize granisetron transdermal, which could increase the level of granisetron transdermal in your blood.
