Ordinary sleep disorders like restless legs syndrome, sleep apnea, insomnia, narcolepsy, shift work sleep disorder, & sleep apnea can negatively influence every aspect of your life, including your relationships, safety, thinking, school & work performance, mental health, weight, as well as the development of diabetes & heart disease. Certainly, not getting good sleep can undoubtedly hurt your quality of life.

Sunosi vs Modafinil

However, some drugs have been approved to treat sleep disorder conditions. This guide explores robust sleep disorder meds — modafinil vs Sunosi. It covers their comparisons & differences, dosage guide, expected negative effects & interactions, as well as where to buy them online from the most reliable vendors. Read it to acquaint yourself with these meds before buying them. But first things first!

What Is Modafinil?

Modafinil dubbed the “smart tab” belongs to a class of nootropics that can heighten brain performance & is sold under the brand name Provigil. It is a med approved to treat sleepiness linked with narcolepsy, shift work sleep disorder (SWSD), & obstructive sleep apnea (OSA). The “smart tab” doesn’t cure these conditions — it only works as long as a user continues to take it.

Off-label, it’s used by physicians to treat other health conditions, including dementia, jet lag, depression, attention deficit hyperactivity disorder (ADHD), chronic fatigue, weight loss, Parkinson’s & Alzheimer’s diseases, etc.

Undoubtedly, the “smart tab” functions by affecting some brain neurotransmitters, including dopamine, histamine, serotonin, orexin, & norepinephrine. Histamine supports individual memory, happiness, learning, & motivation as well as regulates aggression & quality of wakefulness [1]. Besides, orexin is comprehended to regulate the sleep-wake cycle [2]. Dopamine recreates a predominant role in how an individual feel pleasure, think, & plan. This neurotransmitter also aids individuals to remain motivated & focused, as well as regulates sleep & wakefulness [3]. By augmenting the levels of these chemicals, the “smart tab” rewards a lot of positive things aside from encouraging wakefulness.

Healthy individuals use it off-license as a safe & efficacious “smart tab” to heighten cognitive enhancement, where qualities such as alertness, focus, mental acuity, motivation, concentration, & attention are necessitated.

Modafinil Smart Drugs

The drug also heightens the capability to study for longer (especially during exam preparations), helps increase productivity & drive, boosts mental stamina or endurance, & undoubtedly offers a more significant interest in work.

The reasons for taking the “smart tab” by healthy students are due to the fear of academic delinquency, the request to meet high work demands, & overcoming procrastination. Beyond these cognitive reasons, some individuals may also be self-medicating the “smart tab” to treat undiagnosed attention deficit issues that they are experiencing [4].

What Is Sunosi?

This med is used to ameliorate wakefulness in individuals who have too much daytime sleepiness due to particular sleep problems (obstructive sleep apnea (OSA), narcolepsy, etc.). It functions by altering the amounts of certain substances (norepinephrine & dopamine) in the body.

Sunosi contains solriamfetol & it’s a prescription med. It doesn’t cure the cause of OSA & it is highly advised to continue therapy for OSA, such as using continuous positive airway pressure (CPAP), while using this med. The drug doesn’t take the place of your CPAP.

Jazz Pharmaceuticals is the maker of this med & the U.S. Food and Drug Administration (FDA) approved Sunosi on March 20, 2019, & was designated a Schedule IV med by the USA Drug Enforcement Agency on June 2019 [5] [6] [7].

Compare Modafinil and Sunosi

What’s your Sunosi vs. modafinil experience after using? When it comes to how these meds foster wakefulness subjectively, their effects are undoubtedly the same. Individuals who have taken both meds can notice that Sunosi and modafinil are subtle due to the same mechanism of action to promote wakefulness with robust wake-fostering effects.

Definitely, as to how it affects certain brain neurotransmitters to promote wakefulness, their effects are very similar. Indeed, solriamfetol enhanced measures of functioning, quality of life, & work productivity in individuals with OSA & excessive daytime sleepiness [8].

Just like the “smart tab,” Sunosi started functioning within one hour after ingestion.

Modafinil vs Sunosi: Difference Between…

Much of the comparisons have been covered from the table above – both similarities and differences. Certainly, both meds have some limitations. Some have more abuse liability than others, but there is no direct comparison between the two products. Some have more robust wake-fostering properties than the other ones. There have been no head-to-head comparisons, so we can’t tell you how these meds differ when it comes to waking effects.

However, modafinil has a safety profile as being a cognitive augmenter with the earlier mentioned cognitive rewards. The med seems to be the only known & well-researched pharmaceutical drug that qualifies to be an outstanding cognitive augmenter. That’s the reason why many healthy individuals widely use the “smart tab” to heighten their brain function to achieve an edge & to heighten their productivity.

Let’s take a look at other differences between dosage, side effects, & interactions.


Modafinil comes in doses of 100 mg and 200 mg, while Sunosi is available in doses of 75 & 150 mg. These meds should be taken precisely as prescribed by a physician. Follow all directions on the drug leaflet (guides or instruction). Your physician may occasionally change your dose. You may also take Sunosi & modafinil with or without food.

Take Pill

The Sunosi dose may be doubled after 3 days based on its efficacy & tolerability. However, it’s best to maintain a dose of 75 to 150 mg orally once a day. The 150 mg is the maximum daily dose.

Sunosi is usually taken once daily in the morning after waking up. If your physician suggests starting with a 37.5 mg dose, you’ll certainly need to split the 75 mg tab in half. This is the case with modafinil — some individuals may split the 100 mg in half as prescribed.

Depending on the purpose of the “smart tab” treatment, physicians suggest modafinil 200 mg (standard dose) be taken for OSA & narcolepsy (taken once a day in the morning), for SWSD (administered approx. 1 hour before the commencement of the work shift), & other sleep disorder conditions, certain health conditions, for cognitive augmentation or productivity tasks.

Remember that everyone is different. If you aren’t getting the optimal desired results you want with Sunosi or modafinil, talk to your physician about your dosing options. Always monitor any negative effects.

Besides, carefully follow your physician’s instructions about when to increase the dose of these meds. Ingesting more Sunosi or modafinil than prescribed (overdose) will not make it more efficacious & may result in serious negative effects.

Also, your blood pressure, as well as heart rate, must be checked often while using these meds.

Sunosi may be habit-forming, & misuse can certainly cause addiction, overdose, or even death. Like modafinil, don’t change the Sunosi dose or stop taking it without your physician’s advice.

As a “smart tab,” modafinil can be used by any individual who desires to stay awake or boost cognitive functions. Also, dosage should be taken at the right time as prescribed & dose adjustment is needed depending on your health.

Side Effects & Safety

Certainly, some “smart tab”’s negative effects can last for a few days, hours, or minutes & certainly fade away with continual use of med. Its negative effects are normally classified into regular, rare, & reactions to overdose or allergy [10].

Some of the regular negative effects include the following:

  • nausea;
  • insomnia;
  • dizziness;
  • headaches, and others.

In some rare cases, enthusiasts may experience the following:

  • anxiety;
  • depression;
  • hallucinations.

Taking the “smart tab” may indeed induce allergic reactions like severe rashes. Also, the med is likely to induce dizziness or blurred vision. In this regard, don’t drive or operate heavy machinery after taking the “smart tab.”

Pills Side Effects

On the other hand, Sunosi also induces negative effects. The most typical negative effects include the following:

  • lessened appetite;
  • anxiety;
  • headache;
  • nausea;
  • issues sleeping.

These aren’t all the possible negative effects of Sunosi. Always call your physician for advice about negative effects.

Sunosi may also induce serious side effects, including heightened blood pressure & heart rate that can augment the peril of heart attack, heart failure, stroke, & death. Your physician should certainly review your blood pressure before & during the remedy with Sunosi. Dosage adjustment may be needed or stopping it if you develop high blood pressure that doesn’t go away during therapy with Sunosi. Additionally, another serious negative effect that might occur is mental (psychiatric) symptoms, including irritability, anxiety, insomnia, & agitation. Inform your physician if you develop any of these manifestations [11].

Interaction with Other Meds, Food, and Alcohol

Before using Sunosi or modafinil, tell your physician your medical history, particularly of: kidney issues, high blood pressure, heart issues (such as uneven heartbeat), mental/mood concerns (i.e., bipolar disorder, psychosis), individual or family history of substance use disorder (i.e., overuse of or addiction to meds/alcohol).

Other meds may interact with Sunosi & modafinil, including prescription as well as over-the-counter (OTC) meds, vitamins, & also herbal products. Inform your physician about all your current meds & any med you start or recently stopped using.

According to, Sunosi interacts with 81 meds & modafinil interacts with 436 meds [12] [13]. Some of the interactions are minor, while others are major.

Modafinil drug interactions include CYP3A4/5 & CYP2C19 substrates, MAO inhibitors, warfarin, birth control meds, CNS stimulants, and others [14]. Certainly, taking MAO inhibitors with Sunosi med may induce a serious (perhaps fatal) drug interaction. Never take any MAO inhibitors (i.e., isocarboxazid, rasagiline, linezolid, moclobemide, phenelzine, metaxalone, etc.) during therapy with Sunosi [15]. Don’t mix Sunosi with meds that augment blood pressure or heart rate.

Mixing the “smart tab” with alcohol isn’t advised. It can augment the risk of dizziness, impaired judgment, & drowsiness, among other unprecedented negative effects. Besides, it’s not comprehended whether Sunosi interacts with booze. Nevertheless, alcohol can augment sleepiness, which solriamfetol is used to treat in individuals with certain conditions. So, consuming alcohol may indeed counteract the effects of solriamfetol in the body. If you have ever been dependent on or misused alcohol in the past, then bypass taking Sunosi.

There aren’t any specific foods that interact with Sunosi. However, mixing the “smart tab” & grapefruit/juice may augment the actions or negative effects of the “smart tab.”

Final Thoughts: Modafinil vs Sunosi

Which is the supreme med for your desired purpose? Certainly, Sunosi is efficacious in treating sleep disorders linked with OSA & narcolepsy, but it’s not a “smart tab.” Modafinil is a powerful “smart tab” that works longer than Sunosi – approx. 13 or so hours. Both meds are FDA-certified and are safe if used as prescribed.

We recommend you use modafinil if you require a highly studied, very efficacious, & well-tolerated med that not only treats sleep disorders but also offers immense cognitive benefits. Millions of people use modafinil for various purposes. Compared to Sunosi, we conclude that the “smart tab” is indeed a powerhouse when it comes to cognitive-ameliorating effects. Sunosi is just used to foster wakefulness in adults with immoderate daytime sleepiness due to OSA or narcolepsy.
