Levetiracetam (LCT)

Levetiracetam is an anticonvulsant medication used to treat epilepsy. It is the S-enantiomer of etiracetam, structurally similar to the prototypical nootropic drug piracetam. Levetiracetam is generally well tolerated, but may cause drowsiness, weakness, unsteady gait, fatigue, coordination problems, headache, pain, forgetfulness, anxiety, irritability or agitation, dizziness, mood changes, nervousness, loss of appetite, vomiting, diarrhea, throat pain, constipation, and changes in skin pigmentation.Serious side effects may include depression, hallucinations, suicidal thoughts, seizures that are worse or different, fever, sore throat, signs of infection, double vision, itching, rash, swelling of the face. A study published in 2005 suggests that the addition of pyridoxine (vitamin B6) may curtail some of the psychiatric symptoms. A rare side effect of levetiracitam is a pins and needles sensation in the patient"""s legs, similar to neuropathy.
