Xalatan
In brief
- Xalatan is a prescription-only ophthalmic medicine (POM) in the UK.
- Xalatan (latanoprost) is used to lower intraocular pressure in openāangle glaucoma and ocular hypertension; it is a prostaglandin F2α analogue that increases uveoscleral outflow to reduce IOP.
- The usual dose is one drop in the affected eye(s) once daily, preferably in the evening; each drop delivers approximately 1.5 µg of latanoprost.
- Form of administration: topical ophthalmic solution (eye drops) 0.005% (50 µg/mL) supplied in 2.5 mL dropper bottles for instillation into the eye.
- Onset time: IOP lowering begins within about 3ā4 hours after dosing, with measurable effect over the first day and increasing effect over days to weeks.
- Duration of action: effect persists for about 24 hours with onceādaily dosing; longāterm maintenance requires daily use and do not increase frequency.
- Alcohol warning: there is no specific alcohol contraindication; systemic absorption is minimal, but avoid excessive alcohol and consult your clinician if you have respiratory disease or other comorbidities.
- The most common side effect is increased iris pigmentation (often permanent); other frequent effects include ocular irritation, redness and eyelash changes.

Clinical effectiveness in the UK
How well does latanoprost work?
- IOP control: latanoprost provides consistent IOP control when used as prescribed once daily in the evening.
- Adherence: improved when patients receive clear instruction on drop technique.
- Reasons for switching: ocular irritation, cosmetic eyelid or eyelash changes and tolerability.
Latanoprost branded Xalatan and generics perform similarly in routine NHS practice.
Common tolerability complaints are ocular irritation and cosmetic changes around the eyes, which can prompt clinic visits.
Each standard dose is one drop daily and each drop delivers approximately 1.5 μg of latanoprost.
Indications and expanded uses
What is latanoprost authorised for and when is it used offālabel?
- Licensed use
- Lowering elevated intraocular pressure in openāangle glaucoma and ocular hypertension, prescription only.
- Use in practice
- Latanoprost is used as firstāline monotherapy, including where betaāblockers are contraindicated, and as adjunctive therapy combined with other IOPālowering agents; selected paediatric patients from age ā„1 year are treated under specialist monitoring.
| Use | Age limits | Monitoring needs |
|---|---|---|
| Openāangle glaucoma / ocular hypertension | Adults | Regular ocular exams and IOP checks. |
| Paediatric use (specialist) | Children ā„1 year | Close monitoring for side effects and efficacy. |
| Adjunctive therapy | Adults | Monitor IOP and avoid combining multiple prostaglandin analogues. |
Caution: combining several prostaglandin analogues is avoided because paradoxical IOP responses have been reported.
Composition and brand landscape
What is in the bottle and which brands are available in the UK?
| Active ingredient | Concentration | Pack size | Typical manufacturer | Rx status |
|---|---|---|---|---|
| Latanoprost | 0.005% (50 μg/mL) | 2.5 mL dropper vial | Pfizer (Xalatan); generics such as Accord | Prescription only |
The originator Xalatan is supplied by Pfizer in the United Kingdom.
Generic manufacturers of latanoprost include Accord, Teva and Sandoz.
Each standard 2.5 mL bottle delivers roughly 1.5 μg per drop.
Note that some formulations contain benzalkonium chloride as a preservative, and patients with sensitivity should check the preservative content of generics before switching.
Contraindications and special precautions
Who should take extra care or avoid latanoprost?
Absolute contraindications include known hypersensitivity to latanoprost or any formulation components such as benzalkonium chloride.
Relative contraindications that require close monitoring include a history of iritis or uveitis, aphakia, pseudophakia with a torn posterior lens capsule and severe asthma.
Pregnancy and breastfeeding have limited data, so latanoprost should be used only if the anticipated benefit justifies potential risk.
Patients should avoid driving or operating machinery until any transient blurring of vision after instillation clears.
Storage guidance: store unopened bottles refrigerated between 2°C and 8°C and protect from light.
Dosage guidelines
How should latanoprost be dosed for adults and special populations?
| Population | Recommended regimen | Notes |
|---|---|---|
| Adults | One drop in affected eye(s) once daily in the evening | Each drop ā 1.5 μg; do not exceed recommended dose. |
| Paediatric (ā„1 year) | One drop once daily, usually same as adult | Monitor closely for side effects and efficacy. |
| Elderly | One drop once daily | No dose adjustment required. |
| Renal/hepatic impairment | No formal adjustment | Exercise caution in severe hepatic impairment. |
If a dose is missed, resume the next scheduled dose and do not double up.
Overuse can reduce efficacy and may increase local irritation.
Interactions overview
Which medicines and substances affect latanoprost use?
- Latanoprost has limited systemic absorption and clinically significant drug interactions are uncommon.
- Synergistic IOP lowering happens when latanoprost is combined with topical betaāblockers or carbonic anhydrase inhibitors.
- Avoid combining multiple prostaglandin analogues because paradoxical IOP elevation can occur.
Reported adverse events are mainly local, such as hyperaemia, eyelash changes and ocular inflammation.
Serious systemic adverse reports are rare.
No notable food or drink interactions have been identified, and alcohol does not alter ocular efficacy.
Comparable medicines and prescribing preferences
What are the main alternatives on the NHS and how do clinicians choose?
Common class alternatives include travoprost, bimatoprost and tafluprost, all prostaglandin analogues (ATC group S01EE).
Latanoprost is often selected firstāline due to established safety, onceādaily dosing and generic availability.
Bimatoprost may be preferred if enhanced eyelash stimulation is desired or if a patient did not respond adequately to other prostaglandins.
Travoprost offers similar efficacy with minor tolerability differences for some patients.
- Factors guiding choice: efficacy, sideāeffect profile and preservative content.
- Important reminder: do not combine multiple prostaglandin analogues.
Frequently asked questions
-
How do I use latanoprost?
Instil one drop in the affected eye(s) once daily in the evening.
Avoid touching the bottle tip to the eye to prevent contamination.
-
Will it change my eye colour?
Increased iris pigmentation is a recognised and often permanent effect.
Discuss options with the ophthalmology team if you have mixedācolour irides.
-
Can I use other eye drops at the same time?
Wait five to ten minutes between different eye medicines to allow absorption.
Avoid combining prostaglandin analogues.
-
How long is the bottle good for?
Store unopened bottles refrigerated at 2°C to 8°C and protect from light.
After opening, keep at room temperature up to 25°C and discard after six weeks.
Guidelines for proper use
What should pharmacists cover when counselling patients on latanoprost?
- Tilt the head back, pull down the lower eyelid and instil one drop into the conjunctival sac.
- Close the eye for one to two minutes and apply gentle pressure to the inner corner to reduce systemic absorption.
- Use the drops in the evening for optimal effect and to align with recommended NHS dosing practice.
- Store unopened bottles refrigerated at 2°C to 8°C and discard six weeks after opening.
- Advise patients to report severe pain, sudden vision loss or marked redness to ophthalmology promptly.
Community pharmacy services should offer a short demonstration and provide written leaflets or largeāprint labels for older patients.
Encourage reporting of adverse events through the MHRA Yellow Card scheme and document any history of asthma or prostaglandin sensitivity.
