Lasmiditan

Lasmiditan is used to treat the symptoms of migraine headaches (severe throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound and light). Lasmiditan is in a class of medications called selective serotonin receptor agonists. Lasmiditan may work by stopping pain signals from being sent to the brain and stopping inflammation of the nerves that cause symptoms of migraine. Lasmiditan does not prevent migraine attacks or reduce the number of headaches you have.

🔔 How should this medicine be used?

Lasmiditan comes as a tablet to take by mouth. It is usually taken at the first sign of a migraine headache. If your symptoms improve after you take lasmiditan but return within 24 hours, do not take a second tablet. You should not take more than one dose of lasmiditan in a 24-hour period. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lasmiditan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

If you take lasmiditan more often or for longer than the recommended period of time, your headaches may get worse or may occur more frequently. You should not take lasmiditan or any other headache medication for more than 10 days per month. Call your doctor if you need to take lasmiditan to treat more than four headaches in a 1-month period.

Lasmiditan may be habit forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
