Prolatan® should not be used more than once a day, as the more frequent introduction of latanoprost leads to a weakening of the IOP-lowering effect.
If you miss one dose, the next dose should be administered at the usual time.
Prolatan® can be used concomitantly with other classes of ophthalmic drugs for topical use in order to reduce IOP. If the patient simultaneously uses other eye drops, they should be applied at intervals of at least 5 minutes.
The preparation of Prolatan® is included benzalkonium chloride, which can be absorbed by contact lenses. Before dropping drops, contact lenses must be removed and reinstalled after 15 minutes.
Prolatan® can cause a gradual increase in the content of brown pigment in the iris.The change in eye color is due to an increase in melanin content in the stromal melanocytes of the iris, rather than an increase in the number of melanocytes themselves. In typical cases, brown pigmentation appears around the pupil and concentrates on the periphery of the iris. In this case, the entire iris or parts of it become brown. In most cases, discoloration is negligible and may not be clinically established. The enhancement of the iris pigmentation of one or both eyes is observed, mainly, in patients with a mixed color of the iris, which is based on a brown color. The drug has no effect on nevi and lentigo
iris; The accumulation of pigment in the trabecular network or in the anterior chamber of the eye was not noted.
In determining the degree of pigmentation of the iris for more than 5 years, no undesirable effects of pigmentation enhancement have been detected even with the continuation of latanoprost therapy. In patients, the degree of IOP decrease was the same regardless of the presence or absence of enhancement of the pigmentation of the iris. Consequently, treatment with Prolatan® can be continued in cases of increased pigmentation of the iris.Such patients should be under regular supervision and, depending on the clinical situation, treatment can be discontinued.
Strengthening of the pigmentation of the iris is usually observed during the first year after the initiation of treatment, rarely - during the second or third year. After the fourth year of treatment this effect was not observed. The rate of progression of pigmentation decreases with time and stabilizes after 5 years. In more distant terms, the effects of increased iris pigmentation were not studied. After the cessation of treatment of the enhancement of brown pigmentation, the iris was not noted, however, the discoloration of the eyes may be irreversible.
In connection with the use of latanoprost, cases of darkening of the eyelid skin, which can be reversible, are described.
Prolatan® can cause gradual changes in eyelashes and fleece hair, such as lengthening, thickening, increased pigmentation, increased density and changes in the direction of growth of the eyelashes. The eyelash changes are reversible and pass after the cessation of treatment.
Patients who apply drops to only one eye may develop heterochromia.
The use of eye drops can cause a transient blurred vision.
