Epilepsy medication causing kidney issues

Hi My brother had a seizure attack 6 months ago.. Till now we have not found the cause for it. He was prescribed with levipill 500 but we are not able to afford it since it www costly so we consulted a government hospital. They gave sodium valproate 200 mg as medication. Recently my brother is having urinary irritations and redness. Also it seems that he has hepatitis but we tested it came as normal Could some one help me

Any information would be helpful

whats your question?

I have been on sodium valproate for well over 40 years and have had no issues… not sure if this helps
