Imruza 50 Azathioprine Peginterferon alfa-2a [Pegylated Interferon alfa-2a]
ModerateThe leaflet for peginterferon alfa-2a [pegylated interferon alfa-2a] lists azathioprine among the medicines that interact with it. It only says that the two interact and gives no detail on how or what effect to expect. The same list covers drugs metabolized by CYP1A2, and for that group the leaflet's advice is to monitor and adjust the dose of the affected drug.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
