Interactions between your drugs

Major

topiramate lurasidone

Applies to: Topamax (topiramate) and Latuda (lurasidone)

Topiramate can cause increased body temperature and decreased sweating, and these effects may be worsened when combined with medications like lurasidone. Heat stroke and hospitalization may occur in some people, especially in warm weather and during vigorous exercise. Children are particularly susceptible. 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 by your doctor to safely use both medications. You should drink plenty of fluids during warm weather and when exercising, and seek medical attention if you have decreased sweating or a fever. You may also experience drowsiness, dizziness, or lightheadedness when taking these medications together. Therefore, avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the 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

lurasidone food

Applies to: Latuda (lurasidone)

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.
