Waklert 150 mg is a prescription medication containing armodafinil, primarily used to treat sleep disorders such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It functions as a wakefulness-promoting agent, enhancing alertness and reducing excessive daytime sleepiness. The drug works by altering neurotransmitters in the brain, specifically increasing dopamine levels, which contributes to its stimulating effects. Waklert is typically taken once daily in the morning or an hour before the start of a work shift, and it is important to follow a healthcare provider’s guidance regarding its use to minimize potential side effects, which can include headache, nausea, and insomnia.
