The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Bimatoprost (for the treatment of glaucoma and ocular hypertension) comes as a liquid to instill in the eye. It is usually instilled in the affected eye(s) once a day, in the evening. Use bimatoprost exactly as prescribed. Do not use more or less of it or use it more often than prescribed by your doctor. Do not stop using bimatoprost without talking to your doctor first.
To instill the eye drops, follow these steps:
- Wash your hands using soap and water.
- Make sure the dropper tip is not chipped or cracked.
- Do not allow dropper tip to contact your eye or any other surface.
- Tilt your head back, pull down the lower lid of your eye with your index finger to form a pocket.
- While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
- Close your eye for 2 to 3 minutes without blinking or squeezing your eyelids, and tilt your head down as though looking at the floor.
- Place a finger on the tear duct and apply gentle pressure.
- Wipe any excess liquid from your face with a tissue.
- If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
- Replace and tighten the cap on the dropper bottle. Do not wipe or rinse the dropper tip. Keep bottle tightly closed when not in use.
- Wash your hands to remove any medication.
Bimatoprost solution contains benzalkonium chloride, which can be absorbed by soft contact lenses. If you wear contact lenses, remove them before instilling bimatoprost drops and put them back in 15 minutes later.
Bimatoprost (for the growth of eyelashes) comes in a solution that is packaged with 60 sterile, disposable applicators. It is applied once daily at night as follows:
Once nightly, start by ensuring your face is clean, makeup and contact lenses are removed. Remove an applicator from its tray. Then, holding the sterile applicator horizontally, place one drop of bimatoprost on the area of the applicator closest to the tip but not on the tip. Then immediately draw the applicator carefully across the skin of the upper eyelid margin at the base of the eyelashes (where the eyelashes meet the skin) going from the inner part of your lash line to the outer part. Blot any excess solution beyond the eyelid margin. Dispose of the applicator after one use.
Repeat for the opposite upper eyelid margin using a new sterile applicator. This helps minimize any potential for contamination from one eyelid to another.
DO NOT APPLY in your eye or to the lower lid. ONLY use the sterile applicators supplied to apply the product. If you miss a dose, don't try to “catch up.” Just apply it the next evening.
If any solution gets into the eye proper, it is not expected to cause harm. The eye should not be rinsed.
Don't allow the tip of the bottle or applicator to contact surrounding structures, fingers, or any other unintended surface in order to avoid contamination by common bacteria known to cause infections.
Contact lenses should be removed prior to application and may be reinserted 15 minutes following its administration.
Glaucoma: The recommended dosage is one drop in the affected eye(s) once daily in the evening.
Eyelash growth: The recommended dosage is one application nightly to the skin of the upper eyelid margin at the base of the eyelashes only.
