Additional doses may be needed in people with poor immune function but are not necessary for most people. In those who have been exposed to the hepatitis B virus but not immunized, hepatitis B immune globulin should be given in addition to the vaccine. The vaccine is given by injection into a muscle.
Updated October 30, 2014. Neither had I until a friend with multiple sclerosis (who sees the same neurologist that I do) called me to tell me that it had changed her life.. Nuvigil (armodafinil) is a derivative of Provigil (modafinil), which many people with MS take to combat MS-related fatigue. My ears perked up at the excitement in my friend's voice. She went on to tell me that she couldn't tolerate Provigil, as it left her too wakeful to sleep at night.
It is usually taken once a day. If you are taking armodafinil to treat narcolepsy or OSAHS, you will probably take it in the morning. If you are taking armodafinil to treat shift work sleep disorder, you will probably take it 1 hour before the start of your shift. Take armodafinil at around the same time every day. Do not change the time of day that you take armodafinil without talking to your doctor. Talk to your doctor if your work shift does not begin at the same time every day. Follow the directions on your prescription label carefully, and ask our doctor or pharmacist to explain any part you do not understand.
