Hii ... I completely understand your concern.
Yes Arip and Qutan sr can be taken together. Usually given when symptoms are not controlled with one medication.
However both belong to the same class. Taking them together may increase the chances of side effects based on the dosage.
Next Steps
It is best to consult one psychiatrist and follow the single consistent plan.
Inform about the medications your taking to your consulting doctor.
Do not change or reduce the dose of medications on your own, as it may cause relapse of symptoms.
Health Tips
If you're condition is stable your doctor may gradually taper the dose and simplify your medications.
consider online or in person consultation for a clear unified treatment plan.
