Dosage Guide

Quick Answer

The standard dose of Latanoprost (Xalatan) is one drop in the affected eye(s) at BEDTIME every night. More frequent use — do NOT use more than once daily — may paradoxically reduce IOP lowering. Remove contact lenses before instilling and reinsert after 15 minutes.

Dose at a Glance

Adult Dose

One drop in affected eye(s)

Once daily at BEDTIME — bedtime dosing essential (more effective than morning)

Max: Do NOT use more than once daily — may paradoxically reduce IOP-lowering effect

Child Dose (As per ophthalmologist's advice)

Paediatric use under ophthalmologist supervision only

As directed by ophthalmologist

Missed Dose

If the dose is forgotten, use it when you remember. If the next dose (the following night) is close, skip the missed dose and continue on the normal night schedule. Never instil a double dose.

Overdose

Instilling more than one drop at a time may cause eye irritation or redness. If systemic absorption occurs, consult your doctor. Excess drops may paradoxically reduce the IOP-lowering effect.

Frequently Asked Questions

Latanoprost ki standard dose kya hai?

One drop in the affected eye(s) at BEDTIME every night. Do not instil more frequently — use beyond once daily may paradoxically reduce IOP lowering.

Agar latanoprost ki dose chhoot jaye to kya karein?

Instil it as soon as you remember. If the next night is close, skip the missed dose and continue on the normal schedule the following night. Do not instil a double dose.

Latanoprost raat ko kyun daalna chahiye?

Bedtime dosing is scientifically more effective. Due to circadian rhythm, IOP lowering is maximum at night. Effectiveness may be significantly reduced if instilled in the morning.

Kya contact lenses pehen kar latanoprost daal sakte hain?

No — remove contacts before instilling. They can be reinserted after 15 minutes. Benzalkonium chloride (preservative) is absorbed by contact lenses and can cause irritation or damage.

Excess drops may paradoxically reduce the IOP-lowering effect and cause eye irritation. Contact your doctor or ophthalmologist.
