pt girl 13 years old taking 75 mg risperidone tab. she suffering from hypothyrodisim and takes 800 mg altroxin tab. weekly after taking risperidone for 3 months she gained more than 10 kg. is there any interaction between risperidone and thyroxin tab.






If she takes thyroxin and her thyroid hormons level is ok,then she is not hypothyroid and Risperdal causes weight gain.
