Been on 20 mg of prozac (fluoxetine) for 6 months for mild depression and anxiety feeling better is it to soon to taper off?

Might be fine! But,: Always work w/ the Dr on the taper. They can be sure you are not running into w/drawal problems. You are wise to keep use short term if things have improved. I would urge CBT therapy to avoid problems returning via skills and mgmt. Good for you!

MEDICATION: Best to discuss medication with your Psychiatrist. If uncomfortable with your Dr. consult another for a second opinion. Have a physical exam by a Dr. to determine if you have a physical illness. Consult with a Clinical Psychologist for psychotherapy with ZOOM sessions. Fears and anxiety could be heightened due to the Covid-19 pandemic. Stay safe & hopeful to elevate your immune system.
