Medications Can Help Keep Narcolepsy Symptoms Under Control
For most people who have narcolepsy, medications can help with some of the disorder’s most burdensome symptoms, according to Richard K. Bogan, MD, an associate clinical professor at the University of South Carolina School of Medicine and the chief medical officer of the sleep diagnostic company SleepMed, based in Columbia, South Carolina.
Your doctor may suggest the following medications.
Modafinil (Provigil) or armodafinil (Nuvigil): These are central nervous system stimulants that can reduce daytime sleepiness and make you feel more alert. Modafinil or armodafinil are usually prescribed before other kinds of stimulants because they’re less addictive and have fewer side effects. However, new research highlights the need for studying the long-term efficacy of modafinil.
Pitolisant (Wakix): The U.S. Food and Drug Administration (FDA) approved this drug in 2019 for excessive daytime sleepiness in adults with narcolepsy and in February 2026 for children older than 6 with narcolepsy.
Called an oral histamine H3 receptor inverse agonist, pitolisant works on histamine circuits in the brain to improve wakefulness, Dr. Bogan says. Histamine activates brain cells that promote alertness and inhibits neurons that promote sleep. It can also reduce episodes of cataplexy, which is a sudden brief loss of voluntary muscle control triggered by strong emotions.
Oveporexton (Orzeyful): In August, the FDA approved Orzeyful tablets to treat narcolepsy type 1 in adults.
This type can cause cataplexy and lower than usual levels of hypocretin (also called orexin), a key brain chemical that regulates sleep and wakefulness, according to the NINDS.
Orzeyful, an oral tablet taken twice a day, is the first medication for narcolepsy type 1 that treats not just individual symptoms but the full range. It does this by directly targeting the loss of orexin signaling that can cause the disorder.
Solriamfetol (Sunosi): The FDA approved solriamfetol in 2019 for adults with narcolepsy and excessive daytime sleepiness. The medication is thought to work by keeping the brain chemicals dopamine and norepinephrine active.
Amphetamines and similar stimulants: These medications can promote wakefulness by increasing levels of dopamine as well as serotonin and norepinephrine in the brain. Some commonly used for narcolepsy are also used to treat ADHD, such as dextroamphetamine (Dexedrine), a mixture of amphetamines and dextroamphetamine (Adderall), and methylphenidate (Ritalin).
These drugs can come with side effects including irregular heartbeat (arrhythmia), irritability, nervousness, and potential for addiction and abuse.
For this reason, Bogan says such stimulants are used less often now that newer narcolepsy drugs with fewer side effects have become available. “You may also build up tolerance and need higher and higher doses to get benefits,” Bogan says. Careful monitoring is advised when using these medications.
Antidepressants, such as venlafaxine (Effexor) and fluoxetine (Prozac): Venlafaxine and fluoxetine are often effective for controlling cataplexy, as are tricyclics such as imipramine (Tofranil) and desipramine (Norpramin).
Antidepressants can suppress rapid-eye-movement (REM) sleep and increase brain levels of serotonin and norepinephrine, which may help reduce cataplexy. These medications generally tend to cause fewer side effects than amphetamines, but they can cause high blood pressure, sexual dysfunction, and heart rhythm irregularities.
Sodium oxybate (Xyrem, Xywav, Lumryz): Sodium oxybate, which is also known as gamma hydroxybutyrate or GHB, is a strong sedative that can help people with narcolepsy sleep better at night and reduce daytime sleepiness and cataplexy. You take Xyrem and Xywav once at bedtime and again during the night. (You may need to set an alarm to take the second dose.)
Lumryz is an extended-release formula that you take once at night.
Because of high safety concerns associated with the medication (many nonmedical professionals better know it as a “date rape drug”), the distribution of sodium oxybate is tightly controlled, according to MedlinePlus.
You and your doctor have to enroll in a special information program, and the drugs are mailed from a central pharmacy.
