Interactions between your drugs

Moderate

valbenazine lasmiditan

Applies to: Ingrezza (valbenazine) and lasmiditan

Lasmiditan may cause sedation, dizziness, and impaired driving ability. The risk and/or severity may be increased when combined with alcohol or other medications that can also cause sedation. Let your doctor know prior to receiving lasmiditan if you are currently using alcohol or receiving treatment with valbenazine, as you may be more likely to experience sedation-related side effects. 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 medication until your symptoms go away. 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.

Drug and food interactions

Major

valbenazine food

Applies to: Ingrezza (valbenazine)

Grapefruit and grapefruit juice may increase the blood levels and effects of valbenazine, such as drowsiness and an irregular heart rhythm problem called QT prolongation. Irregular heart rhythm problems may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have questions or concerns. Do not add grapefruit products to your diet, or increase or decrease the amount currently in your diet without first talking to your doctor. You may need a dose adjustment of valbenazine or more frequent monitoring by your doctor to safely use both valbenazine and grapefruit products. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these 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.
