Venlafaxine, a medication used to treat depression and anxiety disorders, has been reported to cause various ocular side effects, including blurred vision, dry eyes, and changes in visual acuity. However, these side effects are relatively uncommon and occur in less than 1% of patients taking the drug. If you are experiencing any changes in your vision or other concerning symptoms while taking venlafaxine, you should consult with your doctor. They may recommend adjusting your dosage or switching to a different medication.
