Provigil Patient Switched To Nuvigil

After four years on Provigil, my doctor changed me to Nuvigil because the copyright expired and the maker had to move to a new name by changing an isotope. Nuvigil caused my blood pressure to increase to the point there was a pulsating feeling in my head and a definite lack of concentration -- making a shopping trip difficult, for example. Any other folks with this problem?

Actually, the difference in the medications has nothing to do with changing the isotope for the patent. It is a different isotope/medication, because the new one that was discovered is a longer lasting one, which of course, had to be approved by the FDA and licensed as a new medication, because it is different.

They company still holds the patent for the name brad Provigil and also has the one for the newer medication Nuvigil and both are still available on the market.

Provigil contains the active ingrediet Modafanil and Nuvigil contains the active ingredient Armodafanil, which lasts longer in the human body.

If the Nivigil isn't working for you, then you should talk to your doctor about switching back to the Provigil, especially if it is causing your blood pressure and heart rate to elevate so significantly.

Are there any other questions?
