The real question that is being posed is should one purchase their glaucoma medication at a deep discount from a "foreign" pharmacy? I have patients who are originally from India and Mexico and they travel to their home countries frequently. They have reported to me that they are able to obtain their medications from legitimate pharmacies at much cheaper rates when compared to the U.S. It really makes me wonder why Americans are charge so much more for the same medications (I hear that it has to do with the cost of research and development).
With that being said, it doesn't answer that question about the "foreign" pharmacy YOU are using. The medication could be legitimate, but it could be counterfeit, which is a huge, worldwide problem nowadays. Do you really want to take the chance that you are gettting nothing more than saline, or even worse, something that could harm your eyes. Glaucoma is a potentially blinding condition and requires proper treatment and continued follow-up.
Technically, Lumigan and Latisse are bimatoprost 0.03% and there is no real difference between the two (Lumigan does come in a 0.01% concentration which helps to reduce some side effects like hyperemia or red eyes). Both are designed to be used one drop every night. Lumigan is applied directly to the eye, whereas Latisse is applied to the upper lid with an applicator. Latisse samples come in 3 ml bottles and Lumigan samples come in 2.5 ml bottles, although Lumigan can be purchased in various bottle sizes.
The bottom line is that you need to talk to your ophthalmologist about other medication options to treat your glaucoma if you are unable to afford what he or she has prescribed. Xalatan is now available as a generic in the United States. The generic name is latanoprost. You may also be able to get your doctor to sign you up for a patient assistance program that allows you to receive your medication directly from the pharmaceutical company at no cost.
Good luck.
