In Detailed Information About Modafinil

Why is this medication prescribed?

Modafinil tablet is used to cure the problem of excessive sleepiness which is caused due to narcolepsy (which is a condition that causes extreme daytime sleepiness) or shift work sleep problem. Modafinil is also used along with breathing devices or other treatments to prevent extreme sleepiness caused due to obstructive sleep apnea/hyperpnoea syndrome (OSAHS; a sleep problem in which the patient person temporarily stops respiration or inhales shallowly many times during rest and therefore doesn’t get enough relaxing sleep). Modafinil belongs to the class of medicines named as “wakefulness promoting agents”. This agent works by changing the amounts of certain natural ingredients in the area of the brain that manages sleep and wakefulness.

How should this medicine be used?

Modafinil comes in the form of an oral tablet which is taken by mouth.  It is usually taken once in a day with or without food. If you are consuming modafinil to cure narcolepsy or OSAHS, then you should certainly take it in the morning hours. If you are consuming modafinil tablet to cure shift work sleep problem, then in such case you must take this pill 1 hour before the starting of your work shift. Take modafinil pill simultaneously every day. Do not consume this medication without asking your physician.

Discuss with your physician if your work shift does not start at the same time every day. Adhere to the guidelines on your prescribed label properly, and ask your physician or pharmacologist to describe any part you do not understand. Take Modafinil pill exactly as per instructed.

Modafinil may cause addiction to the individual. Do not take a bigger amount of dosage, take it more often, or take it for a longer period of time than recommended by your physician.

Modafinil may reduce your sleepiness, but it will not treat your sleep disorder. Keep taking modafinil 200mg even if you feel well-rested. Do not stop taking modafinil without talking with your physician because this problem can increase.

Avoid taking Modafinil pill in place of getting enough sleep. Adhere to your physician’s advice about sleeping routines. Keep using any respiration devices or other therapies that your physician has recommended to treat your situation, especially if you have OSAHS.
