Danazol can change how much carbamazepine is in your blood. This may change how well carbamazepine works for you. Danazol may also change how well phenytoin works. Both are epilepsy medicines, so if you take either one, tell your doctor before you start Danazol.
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.
