Hypersomnia Treatment: How Doctors Actually Treat Excessive Sleepiness

It’s been going on for weeks already: No matter how often you get a good night’s sleep — or even sneak in a midday nap — you’re still utterly exhausted. 

You’re having trouble completing even the most basic work tasks, and even your friends and loved ones have noticed you’re out of it most of the time. 

This level of excessive daytime sleepiness, or hypersomnia, simply can’t be ignored anymore, and it’s more than likely you’re dealing with a real medical issue that needs treatment beyond extra nap time. So, what now?

After reading this article, you will have a clear understanding of not only your hypersomnia treatment options, but also why treating hypersomnia will depend on its root cause, why medication may be necessary, and how to manage your recovery expectations. 

Primary vs. secondary hypersomnia: why hypersomnia treatment depends on the cause

While primary hypersomnia is treated directly, secondary hypersomnia is treated by addressing whatever underlying condition is causing your hypersomnia. Primary hypersomnia is excessive daytime sleepiness that occurs on its own; secondary hypersomnia results from a separate condition. This is why treatment for excessive daytime sleepiness will depend on whether you’re experiencing primary hypersomnia or secondary hypersomnia. 

Common types of primary hypersomnia include:

• Idiopathic hypersomnia: hypersomnia with no known cause 

• Narcolepsy: a disorder that affects the brain’s control over sleep and wakefulness. People with narcolepsy often have excessive daytime sleepiness and may fall asleep unexpectedly during the day, even if they slept all night. Type 1 narcolepsy is caused by low levels of hypocretin, a brain chemical. 

• Kleine-Levin syndrome: a rare sleep disorder characterized by long periods of hypersomnia and behavioral/cognitive issues

Causes of secondary hypersomnia can include: 

• Obstructive sleep apnea 

• Hypersomnia associated with a medical disorder (a head injury, a neurodegenerative disease such as Parkinson’s disease, or a neuromuscular disorder such as myotonic dystrophy)

• Hypersomnia associated with a medicine or substance

• Insufficient sleep syndrome (sleepiness due to not sleeping from seven to nine hours a night)

• Hypersomnia associated with a mental disorder (depression; seasonal affective disorder)

Obstructive sleep apnea, however, is “one of the most common and one of the most treatable causes [of secondary hypersomnia],” says Nishi Bhopal, MD, Founder and Medical Director of Pacific Integrative Psychiatry, a Harvard-trained physician triple board-certified in psychiatry, sleep medicine, and integrative and holistic medicine, “which is why it's something we always want to evaluate before reaching for a medication.”

Since excessive daytime sleepiness is a symptom, not a diagnosis, determining the root cause is imperative before beginning hypersomnia treatment. “If the sleepiness is secondary to another condition like untreated sleep apnea, the priority is to treat the underlying cause first,” says Dr. Bhopal. “Medication may still have a role for some patients, but it shouldn't replace treating the condition that's causing the sleepiness in the first place.”

What medications are used to treat hypersomnia?

Hypersomnia medication choice depends on several factors, even though all of these options have the same overall goal — helping people stay awake during the day. Common medications used to treat hypersomnia include wake-promoting agents, dopamine-norepinephrine reuptake inhibitors, histamine-targeting agents, low-sodium oxybate, and traditional stimulants.

“[Each medication] works through different pathways in the brain,” explains Dr. Bhopal, “so they're not interchangeable.”

She goes on to say that when selecting the right kind of hypersomnia treatment, physicians will consider factors like why someone is sleepy, their medical history, other medications they’re taking, and how they respond to treatment.

Some medications are FDA approved for specific conditions, while others may be recommended in clinical guidelines but used off label. Read on for our breakdown of the different kinds of medications used to treat hypersomnia so you can make an informed decision in tandem with your healthcare provider: 

Wake-promoting medications

Wake-promoting medications are often used as a “first-line treatment because they have a long track record and are generally well tolerated,” says Dr. Bhopal. Medications like modafinil (Provigil) and armodafinil (Nuvigil) increase alertness by raising dopamine levels, a wake-promoting neurotransmitter in the brain, per Harvard Medical School’s Division of Sleep Medicine.

According to the 2021 American Academy of Sleep Medicine clinical practice guidelines on central disorders of hypersomnolence, modafinil is strongly recommended as a treatment for both narcolepsy and idiopathic hypersomnia in adults. While armodafinil is also an option for treating narcolepsy and idiopathic hypersomnia, it’s a conditional recommendation from the AASM. That means it’s up to the physician to use their clinical judgment to determine whether armodafinil is the right treatment for their patient.

In addition, wake-promoting medication is an option for treating certain forms of secondary hypersomnia. However, these are all conditional recommendations from the AASM and will require a discussion with your healthcare provider to determine if they are the right treatment for you. 

Armodafinil is suggested as a potential secondary hypersomnia treatment for:

• Dementia with Lewy bodies in adults

• Traumatic brain injury in adults

Modafinil is suggested as a potential secondary hypersomnia treatment for:

• Parkinson’s disease in adults

• Traumatic brain injury in adults

• Myotonic dystrophy in adults

• Multiple sclerosis in adults

Other primary hypersomnia medication treatment options include dopamine-norepinephrine reuptake inhibitors like solriamfetol (Sunosi) and histamine-targeting agents like pitolisant (Wakix).

According to a 2024 study published in Psychopharmacology Bulletin, solriamfetol works by increasing dopamine and norepinephrine signaling; both are neurotransmitters that help maintain wakefulness. “[It] tends to have a stronger alerting effect for some patients,” says Dr. Bhopal. 

Pitolisant, however, works by “targeting the brain’s histamine system,” explains Dr. Bhopal, “which is another pathway involved in maintaining wakefulness.” Histamines, like dopamine and norepinephrine, are neurotransmitters. 

The AASM strongly recommends solriamfetol and pitolisant for the treatment of narcolepsy in adults, while conditionally recommending pitolisant for the treatment of idiopathic hypersomnia in adults.

Oxybates

Unlike other hypersomnia medications, low-sodium oxybate (Xywav) is taken at night rather than during the daytime. Instead of promoting daytime wakefulness, low-sodium oxybate, according to a 2022 study published in Nature and Science of Sleep, combats two major symptoms of narcolepsy while you sleep: excessive daytime sleepiness and cataplexy (weak, paralyzed muscles). 

Although low-sodium oxybate is the sole Food and Drug Administration (FDA)-approved idiopathic hypersomnia treatment, keep in mind that this option is only available through a restricted distribution program, not a retail pharmacy. This is due to the risk of central nervous system (CNS) depression, as well as medication abuse and misuse.

Sodium oxybate (Xyrem, Lumryz) is another option for hypersomnia treatment, albeit with higher sodium levels. The 2021 AASM clinical practice guidelines strongly recommend sodium oxybate for the treatment of narcolepsy in adults, but only suggest it as an option for idiopathic hypersomnia in adults. 

The AASM clinical practice guidelines also suggest sodium oxybate as an option for treating the following instances of secondary hypersomnia:

• Parkinson’s disease in adults

• Narcolepsy in pediatric patients

Stimulants

Traditional stimulants like methylphenidate (Ritalin or Jornay PM) and dextroamphetamine/amphetamine (Adderall) are also effective for reducing sleepiness. Like the wake-promoting agents modafinil and armodafinil, traditional stimulants improve alertness by increasing dopamine levels — a wake-promoting chemical — in the brain. But since stimulants can increase blood pressure and heart rate and produce more side effects they are usually prescribed as a second-line treatment, according to a study published in the Journal of Sleep Research.

The AASM suggests the following as options for the treatment of narcolepsy in adults:

• Dextroamphetamine

• Methylphenidate 

And the following as an option for the treatment of idiopathic hypersomnia in adults:

• Methylphenidate

Medications for secondary hypersomnia

The AASM does suggest wake-promoting medications and sodium oxybate as potential treatment for some forms of secondary hypersomnia. These options should always be discussed with your healthcare provider first. 

Sedating medications (opioids, benzodiazepines) can also cause secondary hypersomnia, so be sure to discuss your prescription history with your healthcare provider as well if you’re experiencing excessive daytime sleepiness.

Can hypersomnia be treated without medication?

Yes, hypersomnia can be treated without medication, but behavioral strategies usually just support treatment rather than resolve primary hypersomnia alone.

“Medication is considered standard care for narcolepsy and idiopathic hypersomnia,” says Jessica Fink, LCSW-S, an Austin-based therapist who specializes in sleep disorders, “but some people opt to manage without it.” 

Fink offers a new behavioral treatment called CBT for Hypersomnia (CBT-H) that, she explains, “was birthed from the observation that medication can only take you so far.” At the same time, Fink cautions that CBT-H was never meant to supplant medication. “It's meant to address the quality of life issues that can remain even in someone who is properly medicated.”

But if your excessive daytime sleepiness is due to factors like chronic sleep deprivation, a circadian rhythm disorder, untreated sleep apnea, thyroid or other medical issues, iron deficiency, or medication side effects, etc., “addressing those issues can significantly improve symptoms without adding another medication,” says Dr. Bhopal. 

If you’re considering hypersomnia treatment at home, Dr. Bhopal recommends adopting healthy sleep hygiene habits like keeping a consistent sleep schedule, getting enough sleep, and exercising regularly. But since they may not be enough to treat your hypersomnia, read on for additional expert advice on strategic sleep and what to avoid:

Sleep scheduling and strategic napping

Dr. Bhopal usually recommends keeping your naps short — about 20 to 30 minutes — and taking them earlier in the day, ideally before 3 p.m., so they don't interfere with nighttime sleep.

“If you need a nap every single day regardless of how much you've slept,” she says, “that's something worth discussing with a sleep specialist because it may suggest an underlying sleep disorder.”

For people living with narcolepsy or idiopathic hypersomnia, Fink advises increasing the number of nurturing activities in the day, and decreasing draining activities, “as energy management is so critical to living with [either condition].” She also recommends having a set and protected regular "sleep window.”

What clinicians recommend avoiding

As calming as they may be, meditations or relaxation practices are “risky for someone with excessive daytime sleepiness,” says Fink. “I recommend modifications — do it standing, with your eyes open, or moving around.”

Dr. Bhopal also advises against overcompensating with excessive caffeine or an irregular sleep schedule:

“Sleeping in for several hours on weekends, taking long afternoon naps, or relying on energy drinks may provide temporary relief,” she says, “but they can actually make your sleep-wake rhythm less stable over time and cause more fatigue and sleepiness.”

How do you get diagnosed and start treatment?

The first step toward diagnosis and treatment is the decision to see a sleep specialist. That initial consultation is critical because, as Dr. Bhopal says, it’s not only about figuring out your hypersomnia treatment plan: “It's to look under the hood to understand why you're sleepy so we can treat the right problem.”

 

What to expect at your first sleep appointment

While a clinician’s questions are essential for diagnosis, Dr. Bhopal says “good sleep evaluation starts with listening.” 

From there, she says, clinicians will ask you questions like: 

• What is your sleep schedule?

• How long have you been sleepy?

• What does your typical day look like?

• Do you snore? 

• Do you stop breathing during sleep? 

• Do you move your legs while sleeping? 

• Do you act out dreams while asleep?

“We'll also review your medications, medical history, mental health, caffeine and alcohol use, and whether you're getting enough sleep in the first place,” continues Dr. Bhopal.

Once the clinician has a better understanding of your medical and sleep history, as well as your symptoms, it’s time for the next step: screening and/or testing. 

“Depending on what we find, testing may include bloodwork to rule out medical contributors,” explains Dr. Bhopal. If sleep apnea is suspected, that will likely mean either a home sleep test or an in-lab sleep study. And if your clinician is evaluating conditions like narcolepsy or idiopathic hypersomnia, that will probably require a Multiple Sleep Latency Test, which measures how quickly you fall asleep in a quiet environment during the day. 

How long does it take to see results from treatment?

It’s important to maintain realistic expectations when it comes to hypersomnia treatment because your results will depend on the cause. 

If you’re treating sleep apnea, for example, you may “begin noticing improvement within days or weeks of effective treatment,” says Dr. Bhopal, “although full recovery can take a few months or longer for some people. (For those trying CBT-H, Fink says it’s a short-term treatment of six to eight sessions.)

Medication for hypersomnia usually works much more quickly, says Dr. Bhopal, “sometimes within days.” But figuring out the right medication and dose may take some trial and error, she warns. “The important thing is that we continue to reassess symptoms rather than assuming one treatment fits everyone.”

What does treatment realistically change? 

The focus of hypersomnia treatment should be more on management, and not necessarily a cure, according to both Fink and Dr. Bhopal. 

“The goal isn't simply to stay awake; we want you to regain your ability to function,” says Dr. Bhopal. She says the outcomes she’s looking for can include patients saying they can get through the workday without struggling to stay alert, or that they no longer need long naps just to make it through the afternoon. Treatment can also allow patients to “drive more confidently, think more clearly, and participate more fully in their daily lives.”

Still, “narcolepsy and idiopathic hypersomnia are chronic illnesses,” acknowledges Fink. “We're not going to cure them. You might need medication for the rest of your life.” This may mean “a lot of mindfulness and acceptance work in addition to the practical skills and tools.”

Not only is idiopathic hypersomnia a chronic illness, it’s also a “legitimate medical sleep disorder,” says Dr. Bhopal. Since this condition can significantly affect one’s ability to work, drive, study, or carry out daily activities, she says it may qualify as a disability depending on the severity of your symptoms.

Hypersomnia treatment can also be an exercise in patience for many people, so Dr. Bhopal advises thinking of treatment “as an ongoing process rather than a quick fix,” and targeting “progress, not perfection.” She says that “most people improve over time when we identify the underlying causes and continue refining the treatment plan.”

How to get sleep care without a referral

The best way to obtain the correct form of hypersomnia treatment for you is through a sleep study. A sleep study can diagnose several sleep-related conditions, including narcolepsy and sleep apnea.

Dreem Health can help with your hypersomnia evaluation by eliminating the typical roadblocks to a traditional in-lab sleep study, such as referral requirements, specialist wait times, and cost barriers. Dreem Health’s at-home sleep study offers a no-referral virtual consultation with board-certified sleep specialists and a full sleep evaluation from the comfort of your own bed. Dreem Health also offers insurance coverage in all 50 states and provides cost estimates before the first consultation.

Dreem Health’s at-home sleep study is the fastest way to get evaluated and potentially rule out sleep apnea — one of the most common causes of hypersomnia — before pursuing further testing for possible conditions like idiopathic hypersomnia. 

The bottom line

Navigating hypersomnia can feel like you’re in a maze with no roadmap, but help is available. The first step is figuring out exactly what is causing your excessive daytime sleepiness, and that starts with a sleep study to diagnose or rule out a common secondary hypersomnia culprit like sleep apnea. Scheduling a home sleep test with Dreem Health is an easy way to find out more. 

If your sleep specialist determines that you have primary hypersomnia due to conditions like narcolepsy or idiopathic hypersomnia, there are effective first-line treatments that can help you manage your symptoms. These treatments usually include medications, which your physician can prescribe depending on the root cause of your hypersomnia. 

Figuring out why you’re so sleepy all the time — and getting the right kind of hypersomnia treatment — could just be the best wake-up call of your life. 

Frequently asked questions (FAQs) 

Is hypersomnia curable, or is it a lifelong condition?

Primary hypersomnia, such as narcolepsy or idiopathic hypersomnia, is not curable. But medications, lifestyle habits, and behavioral therapy can help manage symptoms. Secondary hypersomnia treatment, on the other hand, targets the underlying condition — like sleep apnea — instead of the excessive daytime sleepiness itself. This may result in eliminating your secondary hypersomnia. 

What medication is approved for idiopathic hypersomnia?

The only Food and Drug Administration-approved medication for idiopathic hypersomnia treatment is low-sodium oxybate (Xywav). This prescription is taken at night, and it combats two major symptoms of narcolepsy while you’re asleep: excessive daytime sleepiness and cataplexy. In addition to low-sodium oxybate, the 2021 American Academy of Sleep Medicine clinical practice guidelines on central disorders of hypersomnolence strongly recommend wake-promoting agents like modafinil to treat idiopathic hypersomnia.  

Can Adderall or other stimulants help with hypersomnia?

Yes, Adderall and other stimulants can potentially help with hypersomnia, but they are usually recommended as a second-line treatment if first-line treatments like wake-promoting agents (modafinil, armodafinil) aren’t successful. 

How do I know if my sleepiness is hypersomnia and not something else?

A sleep study, either in an in-person lab or through an at-home evaluation, is the best way to figure out the root cause of your excessive daytime sleepiness. Sleep evaluations are the key to sleep disorder diagnoses like sleep apnea or narcolepsy. Once a sleep study is completed, your clinician will be able to determine if you need additional testing for a potential idiopathic hypersomnia diagnosis. 

How quickly does hypersomnia medication start working?

Hypersomnia medication usually works pretty quickly. However, it’s important to keep in mind that one treatment doesn’t fit everyone, and it may take some trial and error with your healthcare provider’s guidance to find the right medication and dose.

Deep dive recommendations 

If you want to learn more about hypersomnia, Dr. Bhopal recommends Project Sleep, the American Academy of Sleep Medicine, and the Hypersomnia Foundation for reliable patient education resources — but with a caveat that "education is a starting point, not a substitute for a comprehensive sleep evaluation." Similarly, Fink recommends the Narcolepsy Network and Wake Up Narcolepsy for learning more about narcolepsy.
