Latisse is Causing Red Eyes - is It OK to Continue Using It?

I recommend you see an ophthalmologist to make sure your eyes are okay before you continue using the product. A side effect related to Latisse is itchy or red eyes, and your eyes may never get used to this.

Latisse is a medication that can make the eyes red. The more important thing is making sure what the cause of your eye problem. I would see an ophthalmologist to rule out the cause. Remember, Latisse is for cosmetic purposes. Any risk of damaging your eye is not worth it so please get this checked out. 

Latisse can cause an allergic (non-infectious, non-contagious) pink eye (conjunctivitis). Although this sounds like what you are experiencing, I would discontinue use of Latisse and have a thorough examination by an optometrist or ophthalmologist to be sure a SERIOUS infection or ocular inflammation (uveitis) is not present.
Remember, Latisse should NOT be used by women who are pregnant or trying to become pregnant or by nursing mothers. You should discuss all risks, benefits, and alternatives to using Latisse. Some ocular conditions or previous surgeries may preclude use of Latisse. Thses should all be discussed with your physician before beginning this medication.

It sounds like you have CONJUNCTIVITIS. The most common side effects associated with Latisse™ solution (4% of patients) are an itching sensation in the eyes and/or eye redness.
The use of Latisse is CONTRAINDICATED in women who are pregnant or trying to become pregnant or by nursing mothers, in people with active intraocular inflammation (e.g., uveitis), in those with active eye condition, including an eye infection, or have broken eyelid skin, by patients with known risk factors for macular edema or by cataract patients who either had their eye lens removed or replaced with a lens implant.
Stop using the Latisse for a while to allow the process to resolve.
