Monoprost® (Latanoprost) Preservative-Free Eye Drops for Glaucoma

What Monoprost® Is and How It Works

Monoprost is a preservative-free latanoprost ophthalmic solution (50 micrograms/mL) in single-dose containers. It reduces elevated intraocular pressure in open-angle glaucoma and ocular hypertension. Many customers buy Monoprost online to access Canadian pricing, including those managing costs without insurance. YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing.

Monoprost contains latanoprost, a prostaglandin F2α analogue. It increases uveoscleral outflow of aqueous humor, which lowers intraocular pressure. The once-daily dosing is convenient, and the single-use vials avoid preservatives that can irritate dry or sensitive eyes. The product is made by Théa (often seen as Monoprost Thea, or “Monoprost 50 mikrogramm ml Augentropfen” in some listings). It is the same active medicine as in latanoprost monoprost references and common brand or generic latanoprost drops.

Each single-dose unit delivers a sterile solution for one-time use. The recommended dose is one drop in the affected eye(s) once daily, usually in the evening. Regular use helps maintain a stable reduction in pressure. Skipping doses may reduce efficacy.

We source medicines through licensed, vetted partner pharmacies internationally, offering authentic brand products, a broad selection, and fair pricing.

Dosage and Usage

• Usual dose: instill one drop in the affected eye(s) once daily, preferably in the evening.
• Do not use more than once daily; extra doses can reduce IOP-lowering effect.
• If using other eye drops, separate administrations by at least 5 minutes.
• Remove soft contact lenses before administration; wait 15 minutes before reinsertion.
• Wash hands. Twist open one single-dose unit. Do not touch the tip.
• Pull down lower eyelid to form a pocket; instill one drop. Avoid touching the eye.
• Gently press the inner corner of the eye (nasolacrimal occlusion) for 1–2 minutes.
• Discard the opened single-dose unit after use, even if solution remains.
• Missed dose: apply the next dose at the usual time. Do not double up.

• Store unopened single-dose units in the original pouch and carton to protect from light.
• Keep at room temperature, typically below 25°C (77°F). Do not freeze.
• When traveling, carry units in a clean pouch; avoid excessive heat or direct sun.
• Do not use if the pouch is damaged, the solution is cloudy, or the tip is contaminated.
• Keep out of reach of children. Do not reuse a single-dose container.
• For online orders, you can choose prompt, express shipping to the US.

Benefits and Savings

Monoprost is effective at lowering intraocular pressure and is well studied for long-term glaucoma control. The preservative-free design may help reduce ocular surface irritation. Once-daily dosing fits a busy routine and supports adherence. Many people review Monoprost efficacy favorably for sustained pressure reduction.

Ordering from YouDrugstore helps you access Canadian Monoprost price advantages. Typical savings run 60–80% compared with common US pricing. This can lower Monoprost cost for those paying cash or managing out of pocket expenses. Multi-month supplies and select bulk options can reduce the per-month spend. Reorder reminders help you stay on track without running short.

If you are uninsured, you may still save on Monoprost without insurance compared to local US retail. You can also watch for limited Monoprost sale events or a Monoprost deal during periodic promotions.

Side Effects and Safety

• Transient eye irritation, burning, or stinging after instillation
• Conjunctival hyperemia (eye redness)
• Blurred vision right after dosing
• Dry eye or foreign-body sensation
• Eyelash growth, thickening, or darkening
• Periocular skin darkening
• Increased brown pigmentation of the iris over months to years
• Headache or mild eye pain

Serious but uncommon risks include macular edema (higher risk in aphakia, pseudophakia with torn posterior capsule), uveitis/iritis flare, and herpetic keratitis reactivation. Use caution in those with a history of ocular inflammation, complicated cataract surgery, or active eye infection. Asthma symptoms may rarely worsen. Seek medical attention for sudden vision changes, severe eye pain, or signs of infection.

Onset Time

Intraocular pressure begins to drop within 3–4 hours after a dose, with near-maximum effect around 8–12 hours. A meaningful reduction is usually seen within the first week. Full stabilization of response may take 3–4 weeks of consistent nightly dosing. Eyelash changes and iris pigmentation, when they occur, develop gradually over weeks to months.

Compare With Alternatives

Latanoprost is a first-line agent for open-angle glaucoma. Some patients respond well to other prostaglandin-class options. For example, Vyzulta® Ophthalmic Solution (latanoprostene bunod) also targets uveoscleral outflow and adds a nitric oxide donor effect to increase trabecular outflow.

Beta-blocker drops like Timolol lower aqueous production and are often used when prostaglandins are not sufficient or not tolerated. They are usually dosed once or twice daily.

Fixed combinations can simplify regimens. Dorzolamide 2 Timolol 0 5 Ophthalmic Solution combines a carbonic anhydrase inhibitor with a beta-blocker for additive pressure lowering. Regimens are individualized based on response and tolerability.

Combination Therapy

• Latanoprost plus a beta-blocker (e.g., timolol) for additive IOP reduction.
• Latanoprost plus a carbonic anhydrase inhibitor (e.g., dorzolamide) if further lowering is needed.
• Latanoprost plus an alpha-agonist (e.g., brimonidine) as a multi-mechanism approach.
• Separate different drops by at least 5 minutes to avoid washout.
• Adjust schedules with your prescriber to optimize effect and minimize irritation.

Patient Suitability and Cost-Saving Tips

Monoprost is used for adults with open-angle glaucoma or ocular hypertension needing lower pressure. It may be considered for patients with ocular surface disease who prefer preservative-free drops. Those with active eye infections, a history of herpetic keratitis, recent complicated ocular surgery, or uncontrolled inflammation may need alternatives. Use in pregnancy or while breastfeeding requires individualized assessment. Safety and efficacy in children depend on age and clinical judgment.

To manage costs, compare Monoprost price options across sizes and pack counts. Ordering a multi-month supply can reduce the effective monthly cost. Watch for a Monoprost discount or Monoprost save offer during promotions. Reorder reminders help maintain continuity. If you are Monoprost uninsured or paying a Monoprost cash price, Canadian sourcing can lower out of pocket burden. You can also order Monoprost through your account for faster checkout on future refills.
