Interactions between your drugs

Major

mitotane osilodrostat

Applies to: mitotane and osilodrostat

Mitotane may reduce the blood levels of osilodrostat, which may make the medication less effective in treating your condition. On the other hand, if you have been receiving both medications, discontinuing mitotane may increase the blood levels of osilodrostat, which may increase the risk and/or severity of serious and potentially life-threatening side effects such as hypocortisolism (low cortisol levels in the blood), QT prolongation (a heart condition that can lead to irregular heart rhythm), elevated levels of male hormones, high blood pressure, fluid retention, swelling, and hypokalemia (low potassium levels in the blood, which in severe cases can lead to muscle weakness, paralysis, breathing and swallowing difficulties (due to muscle paralysis), and irregular heart rhythm). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Moderate

mitotane food

Applies to: mitotane

High fat food significantly enhances the absorption of mitotane. You should take each dose of mitotane with a full meal containing high fat (e.G., containing milk, chocolate, or oil) and with a full glass of water. Taking mitotane on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication. Talk to your doctor if you have questions or have difficulty taking mitotane with food. It is best to avoid or limit the consumption of alcohol, as it can increase drowsiness or other nervous system side effects of mitotane. You should also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Adrenal corticosteroid inhibitors

Therapeutic duplication

The recommended maximum number of medicines in the 'adrenal corticosteroid inhibitors' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'adrenal corticosteroid inhibitors' category:
