Modafinil prevents sleepiness by affecting certain chemicals in the brain. It is used to treat narcolepsy and to decrease excessive sleepiness in people with obstructive sleep apnea/hypopnea syndrome (in addition to other treatments for the underlying condition).

Buy Modafinil Online is also being studied for its effect on fatigue and cognitive dysfunction in other medical conditions, including multiple sclerosis, idiopathic Parkinson’s disease, and chronic fatigue syndrome.


It is also used along with breathing devices to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS). It is in a class of medications called wakefulness-promoting agents. It works by changing certain chemicals in the brain that control your sleep/wake cycle. It is important to take the correct dosage. Too much can cause serious side effects, such as severe skin rash, including Stevens-Johnson syndrome.

People with narcolepsy feel extremely tired throughout the day and fall asleep suddenly in a variety of situations, such as while talking, eating, or driving. They often cannot remember what they did during the time they were asleep.

This condition is most common in children and teenagers, but it can affect adults as well. It can be a debilitating problem that interferes with work, school, and relationships.

Treatment of narcolepsy focuses on adjusting lifestyle and using medication to improve symptoms. People with narcolepsy can also try to stay on a consistent schedule of sleep and wake times, and they should tell their employers in advance about the condition so that they can explain any issues that may arise. People with narcolepsy should also avoid caffeine, nicotine, and alcohol because they can worsen their symptoms.

Obstructive sleep apnea

Obstructive sleep apnea (OSA) is a sleep disorder that causes a person to stop breathing repeatedly during their sleep. These breathing interruptions, called apneas, usually last for 10 seconds or more. These episodes are accompanied by snoring and daytime sleepiness.

OSA is caused by fat deposits around the upper airway that can block the flow of air. Certain factors increase the risk of developing OSA, including excess weight, age, a thickening of the neck tissue (hypertrophy), and a narrowing of the throat due to a large tongue or enlarged tonsils.

Other diseases and medications also may contribute to the development of OSA, including hypothyroidism, acromegaly, polycystic ovary syndrome (PCOS), and the use of steroids like prednisone.

Treatment for OSA is largely dependent on the severity of the sleep-disordered breathing. The most effective therapy is nasal continuous positive airway pressure, which involves using a device that blows air into the nose while sleeping.

Medications, such as modafinil and Modalert Tablet (a dopamine/norepinephrine reuptake inhibitor), are not usually part of the primary treatment recommendation for OSA but may be used as an adjunct in some patients.

The use of these medications can cause serious or life-threatening side effects. If you experience any severe side effects, talk to your doctor immediately. You should also seek immediate medical attention if you have any signs of a reaction to modafinil, such as skin rash, hives, blisters, mouth sores, trouble breathing or swallowing, fever, dark urine, or yellowing of the skin or eyes.

Shift work sleep disorder

Many jobs require people to work odd hours, and they need to get good sleep so that they can function well during the day. However, atypical sleep schedules often disrupt the natural circadian rhythm of the body and can lead to shift work sleep disorder (SWSD).

Symptoms include trouble falling or staying asleep, difficulty concentrating, fatigue, and poor performance at work. SWSD can also cause other health problems, such as depression, high blood pressure, and obesity.

Shift workers often experience sleepiness while they are on their shifts or afterward. This can interfere with their daily lives, and may even cause accidents or mishaps at work or during family activities. It is possible to overcome shift work sleep disorder by following good sleep habits, such as avoiding caffeine and going to bed at the same time every night.

Modafinil belongs to a group of medications called central nervous system stimulants and prevents sleepiness by stimulating certain parts of the brain. It is used to treat narcolepsy, and can also be used along with breathing devices to reduce excessive daytime sleepiness caused by obstructive sleep apnea/hypopnea syndrome. This medication is available as a tablet that can be taken by mouth. It is usually taken once a day in the morning, or 1 hour before the start of a work shift.

Multiple sclerosis

The disease is characterized by patches of inflammation that can cause the nerves to slow down or jumble the signals they carry. This leads to symptoms and signs like fatigue, slurred speech, trouble walking or balance problems, and muscle spasms.

It can affect different parts of the body, and no two people experience it the same way. The onset and duration of symptoms depend on which part of the central nervous system is affected, as well as how severe it is.

There is no cure for multiple sclerosis, but medicines can reduce the number of flare-ups or attacks and help you manage your symptoms. Steroids and other drugs can ease pain, shorten the length of an attack, and prevent relapses.

Some drugs, called disease-modifying therapies (DMTs), also work against progressive types of MS by altering your immune system’s behavior or repairing damaged myelin.

You can improve your symptoms by following a healthy lifestyle and taking medication as prescribed. Psychological support and physical therapy can also be helpful. Some people have trouble coping with the emotional stress of MS, which can intensify fatigue and other symptoms.

This can be treated with psychiatric medications or psychotherapy. NIH-funded research is working toward developing therapies that will stop or reverse the course of MS, including those that modify the immune system and repair damaged myelin.
