The effect of treatment develops gradually, in most patients up to 2 months. Patients should be warned that the effect of the drug is unstable, and a gradual return to baseline after the discontinuation of use of the drug Latisse is expected. In addition, there may be differences in the length of the eyelashes, their thickness, color intensity, total number of eyelashes or uneven growth, and / or a change in the direction of growth of the eyelashes.
If the patient forgot to apply the drug to Latisse, it is applied at the usual time the next day.
Effect on intraocular pressure (IOP)
Bimatoprost reduces intraocular pressure (IOP) when it is instillated directly into the conjunctival cavity of patients with elevated IOP. In clinical studies, the use of the drug Latisse was accompanied by a decrease in IOP both in patients with high IOP, and with its normal values, but did not reach clinically significant values. With the joint use of the drug Latisse and analogues of prostaglandin (including bimatoprost in the form of eye drops), used to reduce IOP in patients with intraocular hypertension, it is possible to reduce the hypotensive effect. In case the patient receives treatment with analogues of prostaglandins, consultation of the attending physician and monitoring of intraocular pressure are necessary in the appointment of additional therapy with the drug Latisse.
Risk groups
Care should be taken when using the drug in patients with acute inflammatory diseases of the inner shells of the eyeball, for example,because the use of the drug may exacerbate the course of inflammatory phenomena, patients with aphakia, pseudoafacies with rupture of the posterior capsular lens or patients with risk factors for development of macular edema.
Iris pigmentation
Perhaps increased pigmentation of the iris, especially with a dark pigment, this effect can be irreversible. Strengthening the pigmentation of the iris was observed during instillation of eye drops. The change in pigmentation is associated, first of all, with an increase in melanin content, as well as an increase in the number of melanocytes.
The duration of the pigmentation enhancement effect is unknown. The change in the color of the iris against the background of treatment can go unnoticed from a few months to several years. There is no information on the clinical significance of the increase in iris pigmentation in the long term. As a rule, when applying the drug, brown pigmentation around the pupil spreads concentrically to the periphery of the iris, as a result of which the entire iris or individual sectors become more brown.The use of the drug has no effect on the accumulation of pigment on the iris of the eye (nevi and freckles). A significant increase in iris pigmentation is not an indication for the discontinuation of the drug Latisse.
Skin pigmentation eyelids
It was reported that bimatoprost causes darkening of the skin of the eyelids and the periorbital area.
It is assumed that the pigmentation may increase during the entire time of application of the drug Latisse, but in most patients it is reversible and gradually disappears when the drug is withdrawn.
Hair growth outside the treatment zone
It is possible to grow hair on those areas of the skin, on which the drug was accidentally applied. It is important to apply the drug Latisse only to the skin of the edge of the upper eyelid along the line of eyelash growth, using the attached sterile applicator; Do not let Latissa get on your face.
Prevention of microbial contamination of the drug Latisse and applicators
To reduce the risk of eye infection, it is recommended to use the drug Latisse strictly according to the instructions, the tip of the dropper bottle and the applicator brush should not touch any surfaces, nor should you touch them with your fingers.It is necessary to use the attached sterile applicator only once, after use, the applicator is discarded, since re-use of the applicator increases the probability of bacterial contamination of the preparation and its subsequent infection. The result of using an infected drug or an applicator may be infectious inflammation. Cases of bacterial keratitis have been reported with the use of multi-dose vials of ophthalmic agents for topical use.
Use when wearing contact lenses
The drug Latisse contains benzalkonium chloride, which can be adsorbed by soft contact lenses, cause eye irritation and discoloration of soft contact lenses. Contact lenses should be removed before the drug is used, and re-installed no earlier than 15 minutes.
In case of any symptoms from the side of the eye (eye injury, infection complication, etc.), with a sudden decrease in visual acuity, if it is necessary to conduct a planned ophthalmologic operation, and if undesirable reactions occur, you should consult an ophthalmologist to solve the problem about the possibilityfurther treatment with the drug Latisse.
The shelf life of the drug after the first opening of the bottle is 28 days.
