Modvigil 200 mg is a generic form of Modafinil, a prescription medication primarily used to treat sleep disorders such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It belongs to a class of drugs known as wakefulness-promoting agents. Modvigil is widely known for its off-label use in enhancing focus, alertness, and cognitive performance—making it popular among students, professionals, and shift workers.

Modvigil 200 mg works by influencing the brain’s neurotransmitters, particularly dopamine, by blocking its reuptake. This leads to increased levels of dopamine in the brain, which helps promote wakefulness and improved mental function. Unlike traditional stimulants, Modvigil has a lower risk of addiction and fewer side effects.

Its effects typically begin within 1–2 hours of ingestion and can last up to 12–15 hours. Although effective, Modvigil should be taken responsibly and under medical supervision, especially for those with underlying health conditions or who are taking other medications.
