Generic Levetiracetam tablets can sometimes activate psychological problems, especially during the first weeks of treatment, including psychosis, hallucinations, aggression, agitation, anger, hostility, irritability, anxiety, apathy, emotional instability, depression, and attempted suicide. These problems usually fade, but be sure to inform your local physician if you feel one developing; your local doctor may have to stop therapy or adjust your dose. At the beginning of treatment, this drug also can cause extreme drowsiness, unusual weakness, and coordination difficulties. Bring these symptoms to your local doctor's attention. In a few cases, therapy must be discontinued or decreased.
