Not necessarily
Each and every human being is different and choice of medication and dosage is personalised.
If you are doing well on the above mentioned medications, pls continue the same and follow up with your psychiatrist.
FYI, Diva OD can be given up to 2000mg per day and Risperidone upto 12-16mg/day
So you are not on too many medications
Health Tips
Never change the dosage of medications by yourself
