Key takeaways
Tafluprost (Zioptan) and travoprost (Travatan Z) are both prostaglandin eye drops used to lower eye pressure in conditions like open-angle glaucoma and ocular hypertension. They work by helping fluid drain from inside the eye. However, there are some differences between them. Tafluprost (Zioptan) comes in single-use containers, while travoprost (Travatan Z) comes in a multi-use bottle. Tafluprost (Zioptan) is preservative-free, so it may be less likely to cause eye irritation in people with allergies to preservatives. Travoprost (Travatan Z) has a preservative that is gentle on the eyes. Both medications can cause changes in eye color and eyelash growth, but travoprost (Travatan Z) is more likely to cause eye redness. Tafluprost (Zioptan) needs to be refrigerated until opened, while travoprost (Travatan Z) can be stored at room temperature. Both medications are typically used once daily in the evening.
