Modavinil is a generic brand name by Centurion Remedies for the drug Modafinil.
Modafinil is very similar to Armodafinil and are medications that promote wakefulness, attention, focus, and cognitive enhancement. They are also used to treat excessive sleepiness caused by sleep apnea, narcolepsy, shift work and other things such as MS (multiple sclerosis).
Modavinil most often comes in a 200 mg tablet that is taken orally. Modafinil is most often taken once a day with or without food. Some people find that they only need 100 mg of Modafinil in order to enjoy the full benefits. In this case, you can split a single tablet into two pieces to achieve smaller doses. Patients who use this medicine to treat narcolepsy or obstructive sleep apnea should take one pill in the morning and the effects will last all day long due to the long half-life. Those who are using it to combat with shift work disorder should take it one hour before the shift. (If your work shifts do not begin the same time each day, you should talk to your doctor about next steps.) Patients taking modafinil to combat the sleepiness induced by MS (multiple sclerosis) should consider taking slightly higher doses, but at minimum first thing in the morning.
Modavinil is generally well tolerated when taken at prescribed dosages. There have been some common side effects reported in clinical trials and user reviews, including headache, nausea, back pain, anxiety, nervousness, heartburn, indigestion, vomiting, diarrhea, dry skin/mouth, and insomnia. Sometimes side effects are caused by too high of a dosage for personal sensitivities, and trying a lower dosage for a while may help. You may be able to slow increase your dosage back to a normal level if side effects do not return. Insomnia is most commonly caused by taking Modavinil too late in the day. As mentioned previously, modafinil has a long half-life (between 12-15 hours), and its stimulating effects last a long time. It is recommended to take Modavinil in the morning before noon, to avoid sleep disturbances that could occur if it is taken later in the day.
Modavinil, or Modafinil (generic PROVIGIL) is contraindicated in patients with known hypersensitivity to modafinil or armodafinil or its inactive ingredients.
