Uncontrolled painless day time micturition is a serious social problem. Till date, there has been no report in literature of day time uncontrolled micturition in adult patient subsequent to therapy with valproic acid. A young adult male patient with idiopathic generalized tonic clonic seizures was started on valproate but continued to have breakthrough convulsions despite administration of valproate 300 mg twice a day. The dose of valproate was increased to 900 mg per day which controlled seizures but he developed uncontrolled painless passage of urine even during daytime while remaining conscious and alert. Detailed physical examination and investigations did not reveal any abnormality. Keeping in mind, the rare association of valproate with nocturnal enuresis, dose of valproate was decreased to 600 mg leading to abolition of day time enuresis. Unfortunately, convulsive movements returned. The dose of valproate was increased gradually over a period of two weeks to 900 mg per day. Once again, urinary incontinence recurred. Gradual switching over from valproate to carbamazepine controlled his seizures and stopped day time enuresis. In conclusion, this case report highlights the need to keep valproic acid in mind during differential diagnosis of uncontrolled painless day time micturition if this drug is being used in therapy.
