Key takeaways
Lumigan (bimatoprost) and Zioptan (tafluprost) are both prostaglandin eye drops used to lower high eye pressure in conditions like glaucoma and high eye pressure. Lumigan eye drops come in two strengths, with the 0.03% strength only available as a lower-cost generic, and the 0.01% strength brand only. On the other hand, Zioptan is only available as a brand medication, making it potentially more expensive. Lumigan does not need to be refrigerated, but Zioptan must be kept in the refrigerator until the foil pouch is opened. Lumigan contains preservatives to prevent bacteria growth, but Zioptan is preservative-free, which can be beneficial for those with allergies to preservatives. Both medications can cause changes in eye color and eyelash growth, but Lumigan is more likely to cause eye redness. Lumigan starts working within 4 hours and reaches full effect in 8 to 12 hours, whereas Zioptan takes 2 to 4 hours to start working and reaches maximum effect in 12 hours.
