From what I understand, Bimatoprost is a prostaglandin similar to those that are in our bodies anyways. So why does the medication cause side effects and why has it been assigned to pregnancy category C? In other words: why would Bimatoprost do harm to our bodies or an unborn child that the prostaglandins in our bodies wouldn't.
Lumigan and Side Effects - Why?

Latisse not the same as Lumigan
Both Latisse and Lumigan contain the same active ingredient, bimatoprost. However, Lumigan is a glaucoma medication applied directly into the eye while Latisse is applied to the eyelid skin to enhance lash growth, and the formulations are different. Anything approved for application directly into the eye cannot be too toxic, but listing it as category C for pregnant women only means that it has not been tested in that population. Keep in mind too that even completely natural things can cause serious side-effects
Prostaglandins and Side Effects
Prostaglandins or prostaglandin derivatives can be used therapeutically as abortifacients and should not be used in pregnancy.
Lumigan and side-effects
Bimatoprost is in the class of prostaglandins but it is a synthetic analog and does not exist normally in the body. So yes it can cause side-effects. It's like saying trans-fat can cause problems even though chemically it is very similar to normal fat.
