I have a family member who's been suffering with severe fatigue this past week and just recently flu-like symptoms (w/o cough cold or digestive problems - Dr. ruled out flu) just after tapering off Abilify about a week ago. He was put on Lamotrigine as he was tapering off, but now he feels just awful. He has taken Abilify for more than two years. Could this be the cause of his extreme fatigue and flu-like symptoms? He has no other flu-like symptoms except a severe headache. He recently went off because of the expense of Abilify, but I think he should go back on again immediately just so he will feel better. He's missed work, etc. He had a lot of blood work done recently that has ruled out disease of any nature. Please help! We need some answers!
