Doc said severe dry eyes caused by antidepressant taken for 1 year. Reduced dosage by 60% 5 days ago. When will I see improvement in eyes? So far none

May or may not. The drying effects of some antidepressants are quite variable, more typically affecting saliva production than tears. Certainly dry eyes could be contributed to by your antidepressant, but many other causes may be operative here. Any drying effect of your antidepressant is likely to subside within 1 to 2 weeks. No better at all? Seek other explanations for your dry eyes.
