Side Effects of Latanoprost

Blurred vision, burning/stinging/itching/redness of the eye, feeling as if something is in the eye, changes in eyelash number/color/length/thickness, eyelid changes/skindarkening, dry eye, lid crusting/discomfort, increased sensitivity to light, flu-like symptoms, or muscle/joint pain may occur.

This medication may slowly (over months to years) cause brown discoloration of the colored portion of the eye (iris). If you are using latanoprost in only one eye, only that iris may change color. This color change may be permanent but the long-term effects are uncertain. Notify your doctor if this occurs and schedule regular eye exams to monitor it.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
