Drug Interaction Report

Brexanolone may cause excessive sedation and sudden loss of consciousness during the infusion. The risk and/or severity may be increased when combined with other antidepressants or other medications that can also cause sedation. Let your doctor know prior to receiving brexanolone if you are currently using alcohol or receiving treatment with lurasidone, as you may be more likely to experience sedation-related side effects. You should be under close medical supervision by a health care provider during administration of brexanolone. Tell your healthcare provider right away if you feel like you cannot stay awake during the time you are normally awake or if you feel like you are going to pass out. Your healthcare provider may lower your dose or stop the infusion until your symptoms go away. You must have a caregiver or family member with you to help care for your child(ren) during your brexanolone infusion. Do not drive, operate machinery, or engage in potentially hazardous activities requiring mental alertness and motor coordination until the sedative effects have gone away and you know how these medications affect 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.

Avoid consuming grapefruit or grapefruit juice during treatment with lurasidone, as it may increase blood levels of the medication. This can increase the risk of side effects such as Parkinson-like symptoms, abnormal muscle movements, seizures, high blood sugar, diabetes, high cholesterol, weight gain, sex hormone irregularities, and heat-related disorders such as heat intolerance or heat stroke. In addition, you may be more likely to experience side effects associated with low blood pressure such as dizziness, lightheadedness, headache, flushing, fainting, and heart palpitations. You should also avoid the use of alcohol while being treated with lurasidone. Alcohol can increase the nervous system and blood-pressure lowering effects of lurasidone. You may experience increased drowsiness, dizziness, difficulty concentrating, and impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns. Lurasidone should be taken with food consisting of at least 350 calories. Avoid driving or operating hazardous machinery until you know how the medication affects you, and use caution when getting up from a sitting or lying position.
