Pharmacist tips for Lumigan (bimatoprost)

pharmacist
  • Follow up with your eye specialist when instructed (every few weeks or months). You'll do an eye exam to check how well Lumigan (bimatoprost) is lowering the pressure inside your eyes. They can also check for side effects related to the eyes.

    • If you wear soft contact lenses, take them out before each time you use Lumigan (bimatoprost). The preservative in the eye drops can damage the contacts or make them change color. Wait 15 minutes after using the eye drops to put your contact lenses back in.

      • How to use Lumigan (bimatoprost): Wash your hands well with soap and warm water. Tilt your head back and pull down your lower eyelid to make a small pocket. With the other hand, hold the eye drop bottle upside down over your eye. Gently squeeze 1 drop of medication into the pocket. Then, close your eye and lightly press the inner corner of your eye. Wipe away any extra medication on your face.

        • Don't touch the tip of the Lumigan (bimatoprost) bottle with your fingers. Also don't let it touch your eye or anything else. Make sure to keep the bottle capped and closed tightly when you're not using it. This helps make sure you don't get germs in the medication to lower your risk of getting an eye infection.

          • Your vision might get blurry and your eyes could become sensitive to light after using Lumigan (bimatoprost). If this happens, don't drive or use machinery until you can see clearly again. If these problems don't go away or get worse, tell your eye specialist so they can check your eyes.

            • Lumigan (bimatoprost) might make your eyes or eyelids look darker and your eyelashes grow thicker over time. Talk to your eye specialist if you see any changes that worry you.

              • Don't put more than 1 drop of Lumigan (bimatoprost) each day into the eye. Otherwise, it can make the medication not work as well.

                • If you need to use Lumigan (bimatoprost) along with other eye drops, wait at least 5 minutes between each one. This give your eyes enough time to fully absorb each medication.

                  • Keep Lumigan (bimatoprost) at room temperature. It's good to use until the expiration date on the bottle.

                    faqs

                    Frequently asked questions about Lumigan (bimatoprost)

                    Does Lumigan (bimatoprost) need to be refrigerated?
                    No, you don't need to refrigerate Lumigan (bimatoprost). Keep the medication at a temperature between 36ºF and 77ºF.
                    Why is Lumigan (bimatoprost) taken at night?
                    It's best to use Lumigan (bimatoprost) at night. Research shows that prostaglandin eye drops like Lumigan (bimatoprost) work better at controlling eye pressure when used at night. To help you remember, try using the eye drops with something you already do at night. For example, you could use Lumigan (bimatoprost) after brushing your teeth before bed. If using the eye drops at night is a problem for you, talk to your eye specialist.
                    How long does Lumigan (bimatoprost) take to work?
                    Lumigan (bimatoprost) starts to lower eye pressure about 4 hours after you use it. The medication fully kicks in about 4 to 8 hours later. To control your eye pressure best, use the eye drops once a day in the evening every day. After several weeks, your eye specialist will check your eye pressure to see how well the medication is working.
                    How much does Lumigan (bimatoprost) lower eye pressure?
                    In studies, using Lumigan (bimatoprost) once a day for a year lowered eye pressure by 7 mmHg to 8 mmHg. This happened with both the Lumigan 0.01% and generic 0.03% versions of the medication. Follow up with your eye specialist every few weeks or months. They can check how well Lumigan (bimatoprost) is working to bring your eye pressure to the normal range (between 10 mmHg and 20 mmHg).
                    Is latanoprost (Xalatan) the same as Lumigan (bimatoprost)?
                    No, latanoprost (Xalatan) the same as Lumigan (bimatoprost) are different eye drop medications. They work in the same way to lower eye pressure. But studies show that Lumigan (bimatoprost) might work better than latanoprost (Xalatan). Lumigan (bimatoprost) is more likely to cause eye redness as a side effect. But latanprost (Xalatan) might cause headaches more. In addition, you can keep Lumigan (bimatoprost) at room temperature. But for latanoprost (Xalatan), unopened bottles are kept in the refrigerator. Then, they're stored at room temperature for up to 6 weeks once opened. Talk to your eye specialist to compare the medications.
                    Can you use Lumigan (bimatoprost) for eyelash growth?
                    Lumigan (bimatoprost) isn't FDA approved to help eyelashes grow, even though it can be a side effect. Lumigan (bimatoprost) is only approved to lower eye pressure. But there's another medication called Latisse that also has bimatoprost in it. Latisse is FDA approved to help with eyelash growth. Keep in mind that these medications are used in different ways. For Lumigan (bimatoprost), you put the drops into your eye to lower eye pressure. And for bimatoprost (Latisse), you brush the medication on your eyelid at the base of your lashes to help with growth. Talk to a healthcare professional to learn more about ways to help your eyelashes grow.
                    Is Lumigan (bimatoprost) available over the counter?
                    No. You need a prescription for Lumigan (bimatoprost) from a licensed eye specialist.

                    What are the risks and warnings for Lumigan (bimatoprost)?

                    Lumigan (bimatoprost) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                    risk-warning

                    Darker eyes or eyelids

                    Lumigan (bimatoprost) can make the color of your eyes and eyelids darker (browner). This happens because the medication causes the levels of melanin in and around your eyes to go up. Melanin is a protein that's responsible for the color of certain parts of your eyes.

                    You might not notice changes in color until after a few months or years of using Lumigan (bimatoprost). Color changes in the iris (the circular colored part of your eye) are most likely permanent. Your eyelashes and the skin around your eyes might also get darker. But this usually goes away after you stop using the medication.

                    These side effects don't seem to be harmful. But it's best to check in with your eye specialist regularly so they can make sure your eyes stay healthy.

                    risk-warning

                    Eyelash changes

                    Over time, your eyelashes might grow longer or thicker while you're using Lumigan (bimatoprost). You also might have more eyelashes in general. These changes usually go away after you stop using the medication.

                    risk-warning

                    Eye inflammation

                    • Risk factors: Current eye inflammation (e.g., uveitis)

                      Lumigan (bimatoprost) can cause eye inflammation (redness and swelling). It can also make any inflammation worse if you already have eye problems. Tell your eye specialist if you feel eye discomfort or have vision changes while using Lumigan (bimatoprost).

                      risk-warning

                      Swelling of the retina (macular edema)

                      • Risk factors: Not having a lens inside your eye | Having a false lens in your eye | Age-related macular degeneration (AMD) | Genetic eye problems | Eye inflammation | Blocked vein in the eye | Eye surgery

                        Some people who used Lumigan (bimatoprost) had swelling in the retina. This eye condition is called macular edema. Talk to your eye specialist about your risk of macular edema. They'll check your eyes often during treatment.

                        Macular edema can cause vision changes, like blurry vision or colors looking dull. Tell your eye specialist if you notice any changes in your vision while using Lumigan (bimatoprost).

                        risk-warning

                        Risk of bacterial eye infection when using contaminated medication

                        • Risk factors: Problems with the cornea | Injury or damage to the surface of the eye

                          Eye infections can happen if your bottle of Lumigan (bimatoprost) gets germs in it and you use the drops. Some people who used contaminated eye drops got an eye infection called bacterial keratitis. This affects the cornea (the protective covering on the front of the eye). It can cause eye swelling and pain.

                          To lower the risk of this happening, always wash your hands before using Lumigan (bimatoprost). Be careful not to let the dropper tip touch your eye or anything else. Don't touch the tip with your hands or fingers.

                          risk-warning

                          Don't use while wearing soft contact lenses

                          Lumigan (bimatoprost) has a preservative called benzalkonium chloride in it. This preservative can get absorbed by soft contact lenses and damage them.

                          Take out your soft contact lenses before using the Lumigan (bimatoprost) eye drops. Then, wait at least 15 minutes before putting your contacts back in.
