Clearon 400 Deferasirox Phenobarbital
ModeratePhenobarbital can lower the amount of Deferasirox in your body, so Deferasirox may not work as well as it should. Rifampicin, phenytoin and ritonavir can do the same. If you take these together, your doctor may need to raise your Deferasirox dose. Do not change the dose yourself. Your doctor will decide.
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.
