This article will highlight Bimatoprost side effects and ways to manage them.

Apart from this, your eye’s color may change to brown, and the skin around your eye may get darker if you use Bimatoprost eye drops

These changes often take place gradually and are rare, but they might be long-lasting. 

You should know there can be a difference in your eye color after taking Bimatoprost in just one eye. 

Call your doctor immediately If you notice these changes.

To reduce the risk of any side effects, the following precautions need to be taken while having Bimatoprost:

  • Apply the medicine exactly as instructed and remove any excess that comes in touch with other skin, as it can potentially lead to hair growth
  • Inform your doctor if you are allergic to Bimatoprost or any other substances before using this medication. Bimatoprost might have inactive substances, such as preservatives like Benzalkonium Chloride, that could lead to allergic reactions or other issues
  • Inform your doctor about all your medical conditions before using Bimatoprost. It may affect your eyes, including Macular Edema, Iritis, and Uveitis
  • Consult your doctor to continue using your current bottle of Bimatoprost if you get an eye infection or damage or undergo eye surgery. They can suggest you using a new bottle to avoid any contamination
  • Tell your doctor if you are taking any other medications or other supplements, as they may interfere with the working of Bimatoprost
  • Do not start, stop, or change the dosage of any medications without consulting your doctor
  • If you are taking another topical eye treatment, provide it at least 5 minutes before or after administering Bimatoprost eye drops
  • You should be aware that the Bimatoprost solution includes Benzalkonium Chloride, which can be absorbed by soft contact lenses. If you use contacts, take them out before getting bimatoprost and re-insert them after 15 minutes.
If you are pregnant or breastfeeding women, consult your doctor before having Bimatoprost, as it may affect your child’s health.


Bimatoprost can effectively treat Glaucoma and stimulate eyelash growth.

However, inappropriate use of Bimatoprost without a doctor’s prescription can lead to unwanted side effects.

Bimatoprost can lead to redness, itching, and swelling in the eyes.

These effects are usually temporary and vanish with time.

In rare cases, Bimatoprost can cause blurred vision and a change in eye color.

To prevent the risk of any potential side effects, take Bimatoprost only after consulting your doctor in a prescribed manner.
