Side Effects of Using Visine and Latisse?

There are probably no contraindications to using Visine and Latisse concurrently however most ophthalmologists would recommend against the prolonged use of any drop that "gets the red out".  It is OK to use Visine artificial tears or any other brand of artificial tears.  For topical medications, you may want to allow one medication to absorb for 5 to 10 minutes before instilling the second.

Visine and latisse can both cause redness and irritation of the eyes.  If the products do not bother your eyes, go ahead and use them both.  However, use them at least 20 minutes apart.

Visine is an eyedrop that makes your blood vessels smaller, thus causing your eyes to appear less red.  Latisse can cause mild eye irritation and redness in some patients.  I do not recommend using Visine long-term with or without Latisse.  Over time it can cause changes in your blood vessels, that will always make your eyes seem red, even when you try to stop using Visine.  Instead, I recommend using preservative-free artificial tears, with or without Latisse for eye redness and irritation.  You can use those drops indefinitely and without side effects.
