Monopost (latanoprost) preservative-free eye drops cost

Monopost is a preservative-free form of latanoprost, a once-daily prostaglandin eye drop that is MHRA-licensed and NICE-recommended first-line for open-angle glaucoma and ocular hypertension. The drops themselves are inexpensive — from around £10–£18 per pack of 30 single-dose units on a private prescription, or the standard NHS prescription charge. The main private cost is the consultant glaucoma assessment and monitoring that keeps your treatment safe.

Monopost (preservative-free latanoprost 50 micrograms/ml) eye drops cost from around £10–£18 per pack of 30 single-dose units on a private prescription in the UK in 2026, or the standard NHS prescription charge where prescribed on the NHS. Because glaucoma drops must be monitored, the more meaningful cost is the consultant assessment — a private glaucoma consultation with eye-pressure check, OCT and a visual field test typically costs from £200–£350, with follow-up reviews from around £150.

How much does Monopost (latanoprost) cost?

Latanoprost is a low-cost medication. What you pay depends on whether it is prescribed on the NHS or privately, and whether you choose a preservative-free single-dose brand such as Monopost or a preserved multi-dose bottle:

The drops (private Rx)

From £10–£18 per pack of 30 preservative-free single-dose units, typically about a month's supply.

On the NHS

The standard NHS prescription charge per item in England (free in Scotland, Wales and Northern Ireland). A pre-payment certificate can reduce ongoing costs.

Private monitoring

Consultant glaucoma assessment with pressure check, OCT and visual field from £200–£350; follow-up reviews from £150.

What is Monopost and how does it work?

Monopost contains latanoprost, a prostaglandin analogue, in a preservative-free single-dose format. It lowers the pressure inside the eye by increasing the natural drainage of fluid through the uveoscleral pathway. Used as a single drop each evening, it typically reduces eye pressure by around 25–35%, making it one of the most effective single-agent glaucoma treatments and the reason latanoprost is recommended first-line by NICE for most patients with open-angle glaucoma or ocular hypertension.

Being preservative-free, Monopost is often better tolerated by people with sensitive eyes or coexisting dry eye, where the preservative in standard bottled drops can cause stinging or surface irritation over years of daily use. Common, usually mild effects of latanoprost include a gradual darkening and lengthening of the eyelashes, possible darkening of the iris over time, and some redness. Because glaucoma usually has no symptoms until late, drops must be taken every day and pressure checked regularly. Learn more about the condition on our glaucoma overview and the treatment pathway on the glaucoma treatment page.

Not sure your drops are controlling your pressure, or finding preserved drops irritating? A consultant assessment gives you a clear answer.

Other glaucoma drop options

If latanoprost is not tolerated or not enough on its own, your consultant may switch to or add another MHRA-licensed drop. Common UK options include Travatan (travoprost), Ganfort (bimatoprost/timolol) and Cosopt (dorzolamide/timolol). Preservative-free versions are available across most of these for sensitive eyes.

Frequently asked questions

On a private prescription, preservative-free latanoprost single-dose units such as Monopost cost from around £10 to £18 per pack of 30 units, which typically lasts about a month. On the NHS you pay the standard prescription charge per item in England, and nothing in Scotland, Wales or Northern Ireland.
Yes. Monopost is a preservative-free form of latanoprost that is MHRA-licensed in the UK and recommended by NICE as a first-line prostaglandin for open-angle glaucoma and ocular hypertension. It comes as single-dose units, which suit patients who are sensitive to preservatives.
Standard eye drops contain preservatives that can irritate the eye surface, especially with long-term daily use or in people who also have dry eye. Preservative-free latanoprost such as Monopost delivers the same active medicine without the preservative, which is gentler on sensitive eyes and often better tolerated over years of treatment.
The drops are inexpensive, but glaucoma must be monitored to protect your sight. A private glaucoma assessment includes an eye-pressure check, an OCT scan of the optic nerve and a visual field test, typically from £200 to £350, with follow-up reviews from around £150.
Latanoprost is a prostaglandin analogue that lowers eye pressure by increasing the natural drainage of fluid from the eye. It is used as a single drop once daily, usually in the evening, and typically lowers pressure by around 25 to 35 percent. Because glaucoma often has no symptoms, it must be taken every day and your pressure checked regularly.
Your consultant may add or switch to another licensed drop, or recommend SLT laser or surgery. These options have separate costs, which you can see on our SLT laser and glaucoma surgery cost pages.
