Frequent daytime sleepiness can sometimes be linked to conditions such as narcolepsy, obstructive sleep apnea, or shift work disorder. These conditions can affect the normal sleep-wake pattern and make it harder to stay alert during the day.

For certain conditions, healthcare professionals may recommend medicines that promote wakefulness. Modacare 200 mg contains modafinil and may be used under professional guidance to support daytime alertness. Maintaining regular sleep hours and getting enough nighttime rest can also help support a healthy routine.
