HelloPharmacist Editorial Team Bottom Line
Tafluprost ophthalmic solution (Zioptan) is an effective once-nightly eye drop that lowers elevated eye pressure in open-angle glaucoma and ocular hypertension. The most important thing to know is that it can permanently darken the color of your iris, so regular eye exams matter. Follow your evening dosing routine, handle single-dose containers carefully, and tell your eye doctor about any changes you notice.

📖 Tafluprost Ophthalmic: Patient Information Guide

A plain-language walkthrough of Tafluprost Ophthalmic — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for

Tafluprost ophthalmic solution is used to lower elevated pressure inside the eye. Specifically:

  • Zioptan (tafluprost ophthalmic solution) 0.0015% is FDA-approved to reduce elevated intraocular pressure in adults with open-angle glaucoma
  • Zioptan (tafluprost ophthalmic solution) 0.0015% is also approved for adults with ocular hypertension (high eye pressure without glaucoma damage yet)
⚙️How it works

Tafluprost is a prostaglandin analog — a synthetic compound that mimics a naturally occurring substance in the body. It works by binding to FP prostanoid receptors in the eye, which is believed to open up a drainage pathway called the uveoscleral route, allowing fluid to flow out of the eye more easily. Less fluid means less pressure buildup. Eye pressure starts to drop within about 2 to 4 hours of the first dose, with peak effect around 12 hours later.

💊How it's taken

Tafluprost ophthalmic solution comes as a single-dose eye drop container and is applied once each evening. Using it more than once a day is not recommended — doing so can actually reduce how well it lowers eye pressure.

  • One drop in the affected eye(s) every evening
  • If you use multiple eye drops, space them at least 5 minutes apart
  • Open the single-dose container right before use, apply it, and throw the rest away — it cannot be kept sterile after opening
  • Remove contact lenses before applying; wait 15 minutes before putting them back in

Always follow your prescriber's exact instructions and the directions on your prescription label.

🤒Side effects — in detail

The most common side effect is eye redness (conjunctival hyperemia), which affects 4%–20% of people. Other side effects reported include:

  • Eye stinging or irritation (about 7%)
  • Eye itching or allergic-type eye redness (about 5%)
  • Cataracts (about 3%)
  • Dry eye (about 3%)
  • Eye pain (about 3%)
  • Blurred vision (about 2%)
  • Eyelash darkening or increased eyelash growth (about 2% each)
  • Headache (about 6%), common cold (4%), cough (3%)

Rarely, more serious reactions have been reported after approval, including worsening asthma, breathing difficulty, and eye inflammation (iritis/uveitis) — contact your doctor promptly if any of these occur.

⚠️Warnings & precautions
  • Permanent iris darkening: Tafluprost can increase the amount of brown pigment in the colored part of your eye. This change is likely permanent — it does not reverse after stopping the medication. People with partially brown or hazel eyes may be most at risk. The change can take months to years to appear, so regular eye exams are important.
  • Eyelid and eyelash changes: Your eyelashes may become longer, thicker, darker, or more numerous. Changes to eyelid skin pigmentation can also occur. These are usually reversible when treatment is stopped.
  • Eye inflammation: Use with caution if you have active iritis or uveitis — tafluprost can worsen inflammation inside the eye.
  • Macular edema: Swelling at the back of the eye (macular edema) has been reported with prostaglandin eye drops. Risk is higher in people who have had certain types of cataract surgery or who have other risk factors for this condition.
  • Contact lenses: Remove lenses before each dose and wait 15 minutes before reinserting.
🔀What it interacts with

The FDA label for tafluprost does not identify specific drug, food, or supplement interactions. However, if you use other eye drops:

  • Wait at least 5 minutes between each eye drop product to avoid washing one out before it can work

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it
  • Eye inflammation: Tell your doctor if you have active iritis or uveitis — tafluprost may worsen it
  • Prior eye surgery: Tell your doctor if you've had cataract surgery, especially with a torn posterior lens capsule, or if you have risk factors for macular edema
  • Pregnancy: No adequate human studies exist; animal studies at high doses showed fetal harm. Discuss the risks and benefits with your doctor
  • Breastfeeding: It is unknown whether tafluprost passes into human breast milk; use with caution and discuss with your doctor
  • Children: Not recommended for pediatric use due to concerns about permanent pigment changes with long-term use
  • Older adults: No difference in safety or effectiveness has been seen compared to younger adults
📡Pharmacodynamics — effects in the body

Tafluprost begins reducing intraocular pressure approximately 2 to 4 hours after the first dose, with maximum pressure-lowering effect reached at about 12 hours. Using the drops more than once daily does not increase the benefit and may actually reduce effectiveness, so once-nightly dosing is the recommended schedule.

🔬Pharmacokinetics — how your body processes it

After the drop is placed in the eye, tafluprost is absorbed through the cornea and quickly converted into its active form, tafluprost acid, which does the actual work of lowering pressure. Blood levels of tafluprost acid peak about 10 minutes after the drop is applied, but concentrations fall below detectable levels in the bloodstream within 30 minutes, meaning very little reaches the rest of the body. The active metabolite is then broken down through normal metabolic pathways and cleared from the body.

📦How to store it

Store refrigerated at 2° to 8°C (36° to 46°F). Store in the original pouch. stored in the opened foil pouch for up to 30 days at room temperature 20° to 25°C (68° to 77°F).

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Tafluprost Ophthalmic — the kind of thing our pharmacy team would talk through with you at the counter.

Why do I have to use this drop in the evening specifically?
The evening timing isn't just a suggestion — studies show tafluprost works best when used at night, with its peak pressure-lowering effect hitting around 12 hours after you apply it. Sticking to a consistent evening routine also helps make sure it's working at its best during the next morning's hours. Try to use it at roughly the same time each night.
Will this drug change the color of my eyes?
It can, yes — and this is one of the most important things to know. Tafluprost can gradually increase the brown pigment in your iris, which may darken the color of your eye over months or even years. If you use it in only one eye, the two eyes could end up looking different colors. The tricky part is that this iris color change is likely permanent, even if you stop the medication. Your eye doctor will monitor this at your check-ups.
I noticed my eyelashes are getting longer and darker — is that from this medication?
Yes, that's a known and fairly common effect of tafluprost. Your eyelashes may grow longer, thicker, darker, and more numerous while you're using it. The good news is that these eyelash changes are usually reversible — they tend to go back to normal after you stop treatment. Changes to the skin around your eyelid are also possible.
Can I wear my contact lenses when I use this eye drop?
You need to take your lenses out before putting the drop in. After you apply the drop, wait a full 15 minutes before reinserting your contacts. This gives the medication time to absorb properly and avoids the lens soaking up the solution.
What should I do with the little single-dose container after I use it?
Open it right before you're ready to use it, apply the drop to one or both eyes as directed, and then throw the rest away immediately. Even if there's solution left over, the container can't be kept sterile once it's been opened, so saving it for later isn't safe. A new container should be used each time.
Is this eye drop safe to use during pregnancy or while breastfeeding?
There isn't enough human data to say it's fully safe during pregnancy. Animal studies at high doses showed potential harm to developing fetuses, though those doses were far higher than what you'd get from an eye drop. It's also unknown whether tafluprost passes into breast milk. If you're pregnant, planning to become pregnant, or breastfeeding, talk to your doctor so you can weigh the risks and benefits together before continuing treatment.
Is Tafluprost Ophthalmic available over the counter?
Tafluprost Ophthalmic is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Tafluprost Ophthalmic first available?
Tafluprost Ophthalmic has been available in the United States since at least 2012, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Tafluprost Ophthalmic?
Tafluprost Ophthalmic is supplied by 6 manufacturers listed in the FDA NDC Directory, including Sandoz Inc, Thea Pharma Inc., Micro Labs Limited.
