Levetiracetam (Old)

Summary

Levetiracetam is a medication that treats seizures by depressing the central nervous system. This may cause drowsiness, which is an expected side effect that resolves after taking the drug for 4 - 6 weeks. A more severe side effect is a rash that can evolve into the life-threatening Stevens-Johnson syndrome, so any sign of a rash should be reported to the physician. Finally, levetiracetam has been shown to increase suicidal ideation, so keep a close eye on the patient’s mood and anxiety levels.
