If you are going to use bromfenac, your dosage will depend on the particular product you are using. These dosing guidelines usually call for one drop to be applied to the affected eye(s) once or twice daily starting the day before your cataract surgery. You will also use the drops the day of your surgery and for 14 days afterwards.
The dose of bromfenac ophthalmic solution (Bromday®, Prolensa™, Xibrom®) your healthcare provider recommends will vary, depending on the particular product you have been prescribed. As is always the case, do not adjust your dose unless your healthcare provider specifically tells you to do so.
With Bromday and Prolensa (brand-name versions of bromfenac), the usual recommended dosage is one drop into the surgical eye(s) once a day. The usual recommended dosage for Xibrom (brand-name version of bromfenac, which is only available in generic versions) is one drop into the surgical eye(s) twice a day. Because the dosing instructions can vary, it is important to know which particular bromfenac medication you are using.
Treatment normally begins one day prior to cataract surgery, and continues for 14 days after the surgery. Using the medicine for more than one day before surgery or for longer than 14 days after surgery may increase the risk for developing problems with the cornea.
All currently available bromfenac eye drops contain benzalkonium chloride, a preservative that can be absorbed by soft contact lenses. Therefore, you should not wear contacts while using this medication. The prescribing information for Prolensa states that contact lenses can be reinserted at least 10 minutes after you take your dose. The prescribing information for the other bromfenac products simply states that contacts should not be worn while using the medication.
