What is travoprost BAK-free (Travatan Z) used for?
It is used to lower elevated pressure inside the eye (intraocular pressure) in people with open-angle glaucoma or ocular hypertension. It works by increasing the drainage of fluid from the eye. The BAK-free formulation, branded Travatan Z, is free of benzalkonium chloride and instead uses an ionic-buffered (sofZia) preservative system, so it is a gentler drop on the eye surface rather than fully preservative-free. It controls glaucoma but does not cure it.
Does travoprost change the color of your eyes?
It can. Travoprost may cause a gradual increase in brown pigment in the iris, which can permanently change eye color, especially noticeable in people with mixed-color eyes. It can also darken, lengthen, and thicken the eyelashes and darken the eyelid skin. These changes may be permanent even after stopping the drops. Talk with your eye doctor if you notice color changes.
Is travoprost available as a generic?
Yes. Travoprost is available as a generic, including BAK-free (benzalkonium chloride-free) formulations. Generics are generally more affordable than the brand-name Travatan Z, though the cash price can still vary a lot by pharmacy, so comparing prices is worthwhile.
What is the difference between Travatan Z and regular travoprost?
Both contain the same active drug, travoprost, and lower eye pressure the same way. The main difference is the preservative. Regular travoprost is typically preserved with benzalkonium chloride (BAK), while Travatan Z is BAK-free and uses an ionic-buffered (sofZia) system instead. Travatan Z is not preservative-free; it simply avoids BAK, which is intended for people who need better tolerance on the eye surface.
When should you use travoprost eye drops, morning or evening?
Travoprost is usually dosed as one drop in the affected eye or eyes once daily in the evening. Using it at the same time each evening helps keep eye pressure controlled. Follow your eye doctor's specific instructions, and do not use more than directed, as using it more often can make it less effective.

What is travoprost BAK-free (Travatan Z) and how does it work?

Travoprost is a prostaglandin analog, part of the F2-alpha prostaglandin agonist class. It lowers intraocular pressure (the pressure inside the eye) by increasing the outflow of aqueous humor, the fluid that fills the front of the eye. The BAK-free version is preserved with an ionic-buffered system (sofZia) instead of benzalkonium chloride, so it is free of BAK rather than free of all preservatives. It is intended for patients who need gentler tolerability on the eye surface, and it is used to treat high eye pressure in open-angle glaucoma and ocular hypertension.

The usual dose is one drop in the affected eye or eyes once daily in the evening. Travoprost controls glaucoma but does not cure it, so it is typically used long-term. Follow your eye doctor's instructions for how and when to use it.

Travoprost cost and coupon: what to know without insurance

Travoprost is available as a generic, and generics are generally already among the more affordable options compared with brand-name eye drops. Even so, the cash price for the same bottle can differ significantly between pharmacies, which is exactly why comparing prices is worth the effort. There is no manufacturer savings card offered for this drug, so a pharmacy coupon or discount is usually the most practical way to lower an out-of-pocket price.

Rx.com compares prices across more than 60,000 pharmacies to help you find a lower cash price near you. Prices change often and are shown live on this page, so enter your ZIP above to see today's price at pharmacies in your area.

Travoprost alternatives and related eye drops

Travoprost is one of several prostaglandin analog eye drops used to lower eye pressure. Others in the same class include latanoprost and bimatoprost. Doctors sometimes prescribe eye drops from different classes, such as timolol (a beta-blocker) or brimonidine (an alpha agonist), either on their own or in combination.

If you're comparing travoprost with its brand-name and generic forms, see Travatan Z and standard travoprost. Only your eye doctor can decide which drop or combination is right for you; this is background information, not medical advice.

Safety, side effects, and what to watch for

Travoprost has no boxed warning. The most common side effect is eye redness (conjunctival hyperemia), reported in roughly 30 to 50 percent of patients. It may also cause gradual, sometimes permanent changes to eye color from increased brown pigment in the iris, and it can darken, lengthen, and thicken the eyelashes and may darken the eyelid skin. Some people notice changes in the tissue around the eye, such as a deepening of the eyelid crease. Less commonly, it can cause swelling in the back of the eye (macular edema), particularly in people who have had cataract surgery with a torn lens capsule. The label also advises using it with caution in people who have active inflammation inside the eye, such as iritis or uveitis, because the inflammation may get worse.

Remove contact lenses before using the drops and wait 15 minutes before putting them back in. Do not let the dropper tip touch your eye or any surface, to avoid contamination and infection. This medication should not be handled by people who are pregnant or may become pregnant. This is general information and not medical advice; talk with your doctor or pharmacist about your health, other medicines, and any side effects.
