Abilify Maintaina oral equivalent

Hi, anyone know what 400mg Abilify Maintaina is in oral form? I’m kind of worried about being on a strong enough dose to keep me stable.

According to the manufacturer

The recommended starting and maintenance dose of ABILIFY MAINTENA is 400 mg monthly. Healthcare professionals may consider reducing the dosage to 300 mg monthly if a patient experiences adverse reactions

So it either works or it doesn’t at 400mg basically.

I’ve been on 15mg oral daily and was completely stable, but I’ve got a little worse over the past couple of years.
