Latanoprost
About Latanoprost
Latanoprost is a prescription eye drop used to lower high pressure inside the eye in patients with open-angle glaucoma or ocular hypertension. By reducing this pressure, the medication helps prevent damage to the optic nerve, which is crucial for preserving your sight. It is commonly prescribed to protect long-term vision in adults who have built-up fluid pressure in their eyes.
For this medication to work effectively, you must use it consistently every single day, typically once in the evening. Skipping doses can cause the pressure inside your eye to rise again, increasing the risk of permanent vision loss. Along with using these eye drops, maintaining a healthy lifestyle, such as eating green leafy vegetables, staying physically active, and scheduling regular eye pressure checks, can support your overall eye health.
While using Latanoprost, you may experience mild side effects like temporary eye redness, burning, or a gradual darkening of your eyelashes. However, if you experience sudden vision changes, severe eye pain, or swelling of the eyelids, you should contact your doctor immediately. These serious reactions are rare but require prompt medical attention.
Before starting Latanoprost, tell your doctor if you have a history of eye inflammation, herpes simplex eye infections, or if you have had eye surgery. Do not use this medicine if you are allergic to any of its ingredients. It is also important to tell your doctor if you wear contact lenses, as the preservative in the drops can be absorbed by soft lenses.
If you use other eye drops, wait at least five minutes between applying each medication to prevent the liquid from washing out. If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider before using this medicine to ensure it is safe for you and your baby.
Uses of Latanoprost
• Treatment of open-angle glaucoma: Lowers intraocular pressure to prevent optic nerve damage and visual loss.
• Management of ocular hypertension: Lowers high pressure inside the eye, reducing the chance of developing glaucoma.
• Prevention of glaucoma progression: Maintains normal eye pressure, which slows the progression of the disease.
• Improves fluid drainage in the eye: Increases the outflow of aqueous humor, the natural fluid inside the eye.
• Preserves visual function: Reduces the risk of long-term vision impairment caused by high intraocular pressure.
Medicinal Benefits
Latanoprost provides long-term eye care support by helping maintain healthy pressure inside the eyes and protecting vision. By controlling eye pressure consistently, this medicine offers several key health benefits:
- Protection Against Vision Loss: Latanoprost helps keep intraocular pressure within a safe range, reducing the risk of progressive and irreversible damage to the optic nerve caused by high eye pressure.
- Prevention of Silent Eye Damage: Since increased eye pressure often develops without noticeable symptoms, regular use of Latanoprost helps provide continuous protection against hidden changes that may affect eyesight over time.
- Convenient Daily Eye Care Routine: With a simple once-daily application, Latanoprost fits easily into your routine, helping maintain consistent eye pressure control and supporting everyday activities such as reading, driving, and working.
Directions for Use
Always use this medicine exactly as your doctor has instructed. Follow these step-by-step guidelines:
- Wash your hands thoroughly with soap and water before handling the bottle.
- If you wear contact lenses, remove them before using the drops and wait at least 15 minutes before putting them back in.
- Tilt your head back, look upward, and gently pull down your lower eyelid to create a small pocket.
- Hold the dropper bottle directly over your eye without letting the tip touch your eye, eyelashes, or fingers to prevent contamination.

Drug Warnings
- Check the solution: Always inspect the liquid before use. It should be clear and colourless. Do not use the eye drops if the solution is cloudy, discoloured, or contains particles.
- Avoid contamination: Never let the tip of the dropper touch your eye, eyelids, or any other surface. This prevents bacteria from entering the bottle and causing serious eye infections.
- Remove contact lenses: Remember to remove your contact lenses before applying Latanoprost. The preservative in the drops can discolour soft contacts. Wait at least 15 minutes before reinserting them.
- Monitor eye colour changes: Be aware that this medication can cause a gradual, permanent change in your eye colour, making them more brown. This is harmless but should be discussed with your doctor.
- Track the opening date: Write down the date you opened the bottle on the carton to ensure you discard any remaining liquid after 6 weeks.
Drug Interactions
Drug-Drug Interactions:
Inform your doctor if you are taking any of the following medicines, as they may interact.
- Other prostaglandin eye drops: Combining Latanoprost with other similar pressure-lowering eye drops can paradoxically increase the pressure inside your eye or reduce the effectiveness of both treatments.
- Nonsteroidal anti-inflammatory eye drops (NSAIDs): Using certain NSAID eye drops at the same time may slightly decrease the pressure-lowering effect of Latanoprost.
Drug-Disease Interactions:
Inform your doctor if you have a history of the following conditions before taking Latanoprost, as it may worsen your condition or cause complications.
- Eye inflammation (Uveitis or Iritis): If you have active eye inflammation, Latanoprost may worsen swelling inside the eye.
- Macular Edema: Use this medicine with caution if you have risk factors for swelling in the back of the eye (macula), such as a missing or torn lens capsule after cataract surgery.
- Herpes Simplex Keratitis: This medication may reactivate or worsen past viral eye infections.

Habit Forming
Diet & Lifestyle Advise
- Eat eye-healthy foods: Incorporate dark leafy greens (like spinach and kale) and foods rich in vitamins C and E, which support overall optic nerve health.
- Exercise moderately: Regular, moderate aerobic exercise like walking or cycling can help lower pressure inside the eyes. Avoid intense exercises that involve head-down positions, as they can temporarily increase eye pressure.
- Limit caffeine intake: Drinking large amounts of caffeinated beverages in a short period can temporarily raise your eye pressure.
- Stay hydrated gradually: Avoid drinking large amounts of water or liquids all at once. Spread your fluid intake throughout the day to prevent sudden spikes in eye pressure.
- Protect your eyes: Wear sunglasses with UV protection to shield your eyes, as some glaucoma medications can make your eyes more sensitive to light.
Special Advise
Latanoprost may slowly (over months to years) cause brown discolouration of the colored portion of the eye (iris). Notify your doctor if this occurs and schedule regular eye exams to monitor it.
Patients Concern
Disease/Condition Glossary
Ocular hypertension: Ocular hypertension is a condition in which the pressure of the eye is higher than normal. The increased pressure can be due to certain other diseases, an injury, or an adverse effect of certain medications. If left untreated, it can lead to optic nerve damage and permanent vision loss.
Glaucoma: Glaucoma is an eye condition that causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. If it is not treated in time, it may cause blindness. Ocular hypertension is a condition caused by poor drainage of aqueous humour (fluid in the eye that maintains normal pressure by its continuous flow). This leads to a build-up of excess fluid in the eye, resulting in increased pressure inside the eye without any damage to the optic nerve. If ocular hypertension is not controlled, it may lead to glaucoma.
FAQs
Latanoprost is used to lower the intraocular pressure in glaucoma or ocular hypertension patients.
Latanoprost contains Latanoprost, which works by increasing the natural flow of liquid from inside your eye into your bloodstream. This lowers the pressure within your eye and stops your sight from worsening.
You should inform your doctor if you are undergoing dental surgery, and he might stop the use of Latanoprost before the surgery.
Latanoprost may cause eye irritation. If you have dry eyes or any cornea disorder, please consult your doctor before using Latanoprost as a dose adjustment may be required.
No, Latanoprost should not be used simultaneously with other eye medications unless advised by the doctor. At least a gap of 5 minutes should be there between using two eye medications.
No, Latanoprost should be taken in the dose and duration as advised by the doctor. If you take it in more than the recommended dose, it might cause unpleasant side effects. If you think your symptoms are not improving, please consult your doctor.
Side effects of Latanoprost may include changes in your eye colour, blurred vision, changes in the thickness, length, or colour of your eyelashes, irritation, and dry eyes. Most of these side effects of Latanoprost are temporary, do not require medical attention, and gradually resolve over time. However, if the side effects persist, contact your doctor.
Latanoprost contains Latanoprost as an active component.
Latanoprost can be used during pregnancy if advised by the doctor. Very little enters your bloodstream, so it is not considered harmful.
No, there is no evidence that using latanoprost eye drops lowers fertility in either men or women.
You may experience temporary blurred vision after administering the latanoprost drops. If this happens to you, do not drive, ride a bike, or operate equipment or machinery until you can see well again.
Many people with glaucoma can still drive a car or motorcycle, but their eyesight must meet the Driver and Vehicle Licensing Agency's (DVLA) regulations.
Wash your hands before and after use. Shake the bottle well before each use. Instil the eye drops by pulling down the lower eyelid to form a pocket between the eyelid and the eye. Do not touch the tip of the dropper, as it may contaminate the solution.
After using Latanoprost, keep your eye closed for about thirty seconds to one minute to help it absorb properly.
Yes, you can use Latanoprost in the morning if your doctor recommends it based on your medical condition.
Latanoprost may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away, such as stinging, burning, itching, watering, swelling of the eye, redness of the eyelids, irritation, and dry eyes.
In rare circumstances, Latanoprost might cause chest pain (angina) and rapid heart rate (palpitations). However, suppose you already have a cardiac issue, such as atrial fibrillation. In that case, there have been no instances of Latanoprost making it worse.
Yes, Latanoprost can cause a gradual, permanent increase in the brown pigment of your eye, making the colored part (iris) look more brown. This change usually happens slowly over months to years and is typically harmless, but it may be permanent even after you stop using the drops. Talk to your doctor if you have concerns about changes in your eye appearance.
The medication typically starts to lower the pressure inside your eye about 3 to 4 hours after you apply the drop. The maximum effect is usually reached within 8 to 12 hours, which is why it is highly recommended to use it consistently every evening. Talk to your doctor to monitor your progress.
Yes, you can use these drops if you wear contact lenses, but you must remove them before applying the medication. Latanoprost contains a preservative that can be absorbed by soft contact lenses and cause discoloration. You should wait at least 15 minutes after using the drops before putting your lenses back in. Talk to your doctor if you experience persistent irritation.
If you miss a dose, skip it and apply your next drop at your usual time the following evening. Do not apply a double dose to make up for the missed one, as using too many drops can actually reduce the medicine's ability to lower eye pressure. Talk to your doctor or pharmacist if you frequently miss doses.
Clinical studies show that this medicine is most effective at controlling eye pressure throughout the day and night when applied once daily in the evening. Using it at night also helps minimise the impact of temporary side effects, like blurred vision or mild burning. Talk to your doctor for personalised advice on your schedule.
Yes, Latanoprost can cause your eyelashes to grow longer, thicker, darker, and more numerous over time. These changes are usually temporary and will gradually reverse after you stop using the medication. Talk to your doctor if these changes become bothersome or uneven.
There is limited information on the safety of Latanoprost in pregnant or breastfeeding women. It should only be used if the potential benefit justifies the risk to the baby. Talk to your doctor to discuss safer alternatives or protective measures, such as applying pressure to the tear duct after using the drops to limit body-wide absorption.
No, you should not stop using this medication, even if your eye pressure has returned to normal. Glaucoma and ocular hypertension are chronic conditions, and the pressure is only controlled because you are using the drops. Stopping the medicine will cause your eye pressure to rise again, which can damage your vision. Always talk to your doctor before making any changes to your treatment.
