Of course, in addition to the many benefits of Provigil come some side effects. The most serious of these include a severe allergic reaction that affects your liver or blood cells, depression, hallucinations, mania, thoughts of taking your own life, aggression and trouble swallowing or breathing. If you experience any of these side effects, do not take any more Provigil and call you doctor immediately. Less serious side effects associated with this drug include headaches, nervousness, stuffy nose, back pain, feeling anxious, sleep problems, dizziness and upset stomach. If you have heart problems, high blood pressure or liver or kidney problems, speak to your doctor before taking this medication.
While there are many benefits of Provigil, it should be known that this medication can speed up or slow down the removal of other medications from your system by affecting specific liver enzymes. Among these medications are some antidepressants and MAO inhibitors. This is why it's of the utmost importance to tell your doctor about any medications you are taking before taking Provigil.
