Modalert 200 mg is a prescription medication containing Modafinil, a powerful wakefulness-promoting agent. It is commonly used to treat narcolepsy, shift work sleep disorder (SWSD), and obstructive sleep apnea (OSA)-related excessive daytime sleepiness. Modalert works by stimulating brain activity, helping users stay alert and focused throughout the day. This nootropic is also widely used off-label by students, professionals, and night-shift workers to boost productivity and cognitive performance. It is usually taken once daily in the morning or an hour before a shift, with effects lasting up to 12–15 hours. Always follow your healthcare provider’s dosage instructions to minimize side effects like headache, nausea, insomnia, or anxiety.
