Modvigil 200 mg (Modafinil) is not specifically designed for men. It is equally effective in men and women. The meds are prescribed to promote wakefulness in people with conditions such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder, regardless of gender. Its effectiveness is based on individual factors such as underlying medical conditions, health conditions, and how the body metabolizes the drug. Both men and women should consult with a doctor to determine whether Modvigil is right for their needs.
