Consumer information for this interaction is not currently available.
GENERALLY AVOID: Concurrent use of multiple prostaglandin analogs, as well as more frequent administration of a prostaglandin analog than recommended, may reduce the intraocular pressure (IOP) lowering effects of these agents. A case series of 3 patients described IOP elevations of 6 to 23 mmHg two to five weeks after bimatoprost was added to a latanoprost regimen. The precise mechanism of interaction has not been established, although the combination exceeded the dose-response curve, which may have led to the paradoxical effects on IOP. Other factors such as disease state and patient compliance may also have contributed. In a randomized clinical trial of 18 patients with non-advanced primary open angle glaucoma, mean IOP increased by 1.8 mmHg four weeks after the addition of bimatoprost to preexisting latanoprost treatment, but returned to baseline after discontinuation of bimatoprost.
MANAGEMENT: Concomitant administration of two or more prostaglandin analogs, or more frequent administration of a prostaglandin analog than approved by the manufacturers, is generally not recommended.

Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
