For the treatment of high eye pressure or open angle glaucoma, the recommended dosage of bimatoprost is one drop applied to the affected eye once daily. If you use other eye drops, wait at least five minutes after using bimatoprost before using the other eye drop. Make sure to follow bimatoprost dosing guidelines carefully, as using the drug more than once daily can reduce its effectiveness.
The dosage of bimatoprost ophthalmic solution (Latisse®, Lumigan®) your healthcare provider recommends will vary, depending on whether you are using the drug to treat high eye pressure (or glaucoma) or to enhance eyelashes. As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
The recommended dose of bimatoprost for treating high eye pressure (ocular hypertension) or open angle glaucoma is one drop into the affected eye(s) once daily in the evening. Interestingly, using bimatoprost more frequently than once a day actually makes it less effective. Only the Lumigan formulation of bimatoprost is approved for this use. This dosage is the same for either strength of Lumigan (0.01% or 0.03%).
Bimatoprost Dosage for Eyelash EnhancementThe standard bimatoprost dosage for eyelash enhancement is one drop (applied with the special applicator) to the skin of the upper lash line of each eye once a day at night (one drop per eye). Using it more often or applying a larger dose will not improve your results (although it could increase your risk of side effects).
Keep in mind that you will probably see results gradually, and most people do not notice a significant improvement for about two months after starting Latisse. Additionally, the eyelashes will gradually return to their previous state after you stop using bimatoprost.
Only the Latisse formulation of bimatoprost is approved for this use.
