People who take modafinil, a drug known for making people more awake, usually stay awake and aware for a long time. Different people can feel its affects for different amounts of time, but on average, one dose of Modafinil can keep you awake for 12 to 16 hours.
Modafinil normally starts to work 30 to 60 minutes after it is taken, and it reaches its highest level in the bloodstream 2 to 4 hours later. It’s a good choice for people with narcolepsy, obstructive sleep apnea, and shift work sleep disorder because it keeps them awake for a long time.
The length of Modafinil’s affects depends on the person’s metabolism, health, and whether or not they have food in their stomach. Modafinil makes you more awake, but it doesn’t mean you don’t need to get enough sleep every night. It is important to follow the directions that a doctor gives you when taking Modafinil to make sure it works well and safely to treat sleep problems and wakefulness issues.
