It is also a white crystalline powder that is substantially insoluble in cyclohexane and water. It is however slightly soluble in acetone and methanol. The Provigil tablets consist of 100mg to 200mg of modafinil.

Indications of Using Modafinil

Modafinil is helpful in improving wakefulness in patients having extreme sleepiness linked with (OSA) obstructive sleep apnea, narcolepsy, or (SWD) shift work disorder.

Limitations of Usage

In obstructive sleep apnea, it is known to treat extreme sleepiness and not as a treatment or cure for the present obstruction. Always inquire from a medic for the best prescription on how to use the drug. The recommended usage for users with OSA or narcolepsy is about 200gm. They should consume the dosage once a day, particularly in the morning. Besides, a dosage of approximately 400gm a day is tolerable in certain situations. However, there are no recorded benefits recorded after consuming 400gm a day as opposed to the 200mg a day.

The recommended dosage for patients with Shift Work Disorder is 200mg a day. It should be consumed orally and probably one hour before starting a shift. For users with extreme hepatic impairment, the dosage must be lowered to a half of that recommended to users with standard hepatic function. Besides, patients with geriatric should use modafinil in lower doses for better functioning.

If you suspect an overdose to a patient, get the medication right away or contact your poison control department. Ensure that you tell them the quantity of modafinil that the patient has taken and how it occurred.
