Why is this medication prescribed?
Solriamfetol is used to treat excessive daytime sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness). Solriamfetol is also used along with breathing devices or other treatments to prevent excessive daytime sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore doesn't get enough restful sleep). Solriamfetol is in a class of medications called wakefulness promoting agents. It works by increasing the amounts of certain natural substances in the brain that controls sleep and wakefulness.
How should this medicine be used?
Solriamfetol comes as a tablet to take by mouth. It is usually taken once a day with or without food as soon as you wake up in the morning. Take solriamfetol at the same time every day. Do not take solriamfetol within 9 hours before you plan to go to bed because it may cause difficulty falling asleep or staying asleep. Do not change the time of day that you take solriamfetol without talking to your doctor. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take solriamfetol exactly as directed.
Your doctor will probably start you on a low dose of solriamfetol and gradually increase your dose, not more than once every 3 days.
Solriamfetol 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.
Solriamfetol may decrease your sleepiness, but it will not cure your sleep disorder. Continue to take solriamfetol even if you feel well-rested. Do not stop taking solriamfetol without talking to your doctor.
Solriamfetol should not be used in place of getting enough sleep. Follow your doctor's advice about good sleep habits. Continue to use any breathing devices or other treatments that your doctor has prescribed to treat your condition, especially if you have OSAHS.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

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).
Store solriamfetol in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many tablets are left so you will know if any are missing.

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
