Currently, Latisse does not have a generic equivalent. Medications typically have two names, a "brand" name and a "generic" name. With regards to Latisse, Latisse is the "brand" name and bimatoprost is the "generic" name. Both names will appear on the box when you purchase it. Because this medication is still under patent, no other companies can manufacture bimatoprost, so you will only find it under the BRAND NAME. Once the patent expires, then other companies will be able to produce it under the generic name alone.
Xalatan is another prostaglandin used for glaucoma and its patent recently expired. It can now be purchased exclusively as a generic under the generic name latanoprost. Unforunately, this medication is not FDA-approved for eyelash growth. It is FDA-approved for the treatment of ocular hypertension and glaucoma.
