Edit list (add/remove drugs)

Interactions between your drugs

Moderate

mitotane vamorolone

Applies to: mitotane and Agamree (vamorolone)

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with strong inducers of CYP450 3A4 or the pregnane X receptor (PXR) (e.g. carbamazepine, phenytoin, rifampin, St. John's wort) may decrease the plasma concentrations of vamorolone leading to a lack of efficacy. Vamorolone is partially metabolized in vitro by CYP3A4. The clinical significance of this interaction is unknown.

MANAGEMENT: Some authorities recommend considering the use of alternative treatments that are not strong inducers of CYP3A4 during concomitant use with vamorolone due to reduced vamorolone efficacy. No dose adjustments are recommended. The possibility of decreased corticosteroid effects should be considered. Patients should be monitored for signs and symptoms of steroid withdrawal and secondary renal insufficiency, including anorexia, hypoglycemia, nausea, vomiting, weight loss, muscle wasting, fatigue, weakness, dizziness, postural hypotension, depression, and adrenal crisis manifested as inability to respond to stress (e.g., illness, infection, surgery, trauma).

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.

Moderate

vamorolone food

Applies to: Agamree (vamorolone)

Grapefruit juice may increase the blood levels and effects of vamorolone. This may increase the risk and/or severity of side effects such as swelling, weight gain, electrolyte abnormalities, high blood pressure, high blood glucose, muscle weakness, depression, mood swings, acne, thinning skin, stretch marks, easy bruising, cataracts, glaucoma, excessive growth of facial or body hair, and abnormal distribution of body fat, especially in the face, neck, back, and waist. Other side effects that may occur include decreased ability to fight infections, increased risk of developing infections, and inadequate response to stress such as infection, surgery, trauma, or a severe asthma attack. Talk to your doctor if you have any questions or concerns. 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.
