    Description

    Lasmiditan is used to treat acute migraine headaches with or without aura. It is not used to prevent migraine headaches. Lasmiditan works in the brain to relieve the pain from migraine headaches.

    Lasmiditan is not an ordinary pain reliever. It will not help with any kind of pain other than migraine headaches. This medicine is usually used in people whose headaches are not helped or relieved by acetaminophen (Tylenol®), aspirin, or other pain relievers.

    This medicine is available only with your doctor's prescription.

    This product is available in the following dosage forms:

    • Tablet

    Before Using

    In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of lasmiditan in the pediatric population. Safety and efficacy have not been established.

    Geriatric

    Although appropriate studies on the relationship of age to the effects of lasmiditan have not been performed in the geriatric population, geriatric-specific problems are not expected to limit the usefulness of lasmiditan in the elderly. However, elderly patients are more likely to have dizziness, and age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving lasmiditan.

    Breastfeeding

    There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

    Precautions

    It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.

    Check with your doctor if you used this medicine and your migraine did not go away, or if your migraine got worse or started occurring more often.

    Lasmiditan may cause drowsiness or dizziness. Wait at least 8 hours after taking lasmiditan before you drive, use machines, or do anything else that requires you to be alert.

    Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

    Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with lasmiditan may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

    Using lasmiditan alone or in combination with other migraine medicines for 10 or more days per month may lead to worsening of headache. You may keep a headache diary to record your headache frequency and drug use.

    Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
