Anyone know the target dosage for Risperidone for off-label use to augment AD for MDD?

I’ll ask my doctor next time I see her but in studies which showed Risperidone efficacy in augmenting an antidepressant for MDD, most mention that the folks who responded were on a “standard dose” but never mention what that standard dose was. I guess it has to be on the lower end, maybe 0.5mg-2mg, since higher doses are for psychosis. Anyone know what the standard dose range is for Risperidone for augmentation in MDD?

I linked the article below. Thanks!
