There are many levetiracetam brand names available from different manufacturers here. Livpil, levenue, levespy, levera, levesam, keppra. Which one do you suggest and have you noticed a certain brand with the least side effects related to memory, sleep & irritability? Is there any that doesn't cause the famous Keppra rage the anger issue and is better for memory & sleep? I read in the international market that their patients' side effects differ for the brand Keppra and the generic one, even the quality & effectiveness. Which one do you suggest here in India that's effective without causing much irritability, memory & sleep issues?
