Xalatan Dosage/Direction for Use

Use in adults (including the elderly): One drop in the affected eye(s) once daily. Optimal effect is obtained if latanoprost is administered in the evening.
The dosage of latanoprost should not exceed once daily since it has been shown that more frequent administration decreases the IOP lowering effect.
If one dose is missed, treatment should continue with the next dose as normal.
Latanoprost may be used concomitantly with other classes of topical ophthalmic drug products to lower IOP. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five minutes apart.
Contact lenses should be removed before instillation of the eye drops and may be reinserted after fifteen minutes (see Precautions).
Pediatric population: Latanoprost eye drops may be used in paediatric patients at the same posology as in adults.
No data are available for pre-term infants (less than 36 weeks gestational age). Data in the age group <1 year (4 patients) are limited (see Pharmacology: Pharmacodynamics under Actions).
