Reddened sclera of the eyes is not the most pleasant phenomenon, which can be caused by lack of sleep, overwork, and excessive strain on the organs of vision. Regardless of the cause of this condition, it gives a person a tired, broken look and gives a lot of discomfort.
Scleral redness may look different. In some cases, dilated vessels are visible on the whites of the eyes, and in others, the sclera acquires a uniform pink hue (in situations where small capillaries are involved).
Vascular dilatation occurs not only on the so-called white eye, but also on the mucous membrane of the eyelids - they are also hyperemic and look swollen.
This flaw cannot be hidden with makeup. Therefore, special ophthalmic agents are a real salvation for owners of tired red eyes. In particular, patients are prescribed the drug "Iridine" - eye drops with a vasoconstrictor effect.
Composition
The active active substance is naphazoline hydrochloride. Therefore, any drug that has a similar composition, including the widely known "Naphthyzine", is an analogue. "Iridine" - drops for the eyes, which are positioned as a cosmetic product, but in fact are a pharmaceutical preparation. The analogue also includes the drug "Polinadim" from a Russian manufacturer.
Operating principle
Redness of the mucous membrane of the eyes and eyelids is associated with the expansion of small blood capillaries, abundantly localized in the structures of the eyeball. The "whitening" effect of the drug "Iridine" (eye drops) is a consequence of the vasoconstrictor effect of the active component.
Nafazolin, which is the active ingredient in Iridine eye drops, belongs to the class of alpha-adrenergic agonists. Causing the excitation of alpha-adrenergic receptors, naphazoline hydrochloride provides a vasoconstrictor effect. That is why redness disappears from the mucous membrane of the eyes.
Indications for use
- Redness of the mucous membrane of the eyeball.
- Irritation, swelling on the eyelids.
- Discomfort in the form of burning eyes or itching.
- Increased lacrimation, lacrimation.
- Hypersensitivity of the eyes to light (both daylight and artificial lighting).
Before you start using this tool, it is highly advisable to consult an ophthalmologist to clarify the indications and receive recommendations on the optimal regimen for the use of the drug "Iridine". Drops for the eyes are considered safe, but their improper use can provoke adverse reactions. Dosage should be compiled individually.
The drug "Iridine" (eye drops): instructions for use
Drops to eliminate redness are recommended before applying makeup on the eyes. In the conjunctival cavity of each eye, 1-2 drops of the drug are instilled (it is more convenient to do this in the supine position).
The whitening effect occurs after a few minutes and lasts for several hours.
Important! Installation is allowed no more than three times a day.
Every 5-6 days you need to take a break to avoid getting used to it.
Adverse reactions
Is the use of the drug "Iridine" safe? Drops for the eyes (instructions and reviews of doctors confirm this) can cause adverse reactions:
- Itching, burning, other unpleasant sensations from the mucous membrane of the eye immediately after instillation of the drops.
- The development of tolerance (resistance) to the action of the drug in case of prolonged regular use.
- Often with frequent prolonged use, the opposite effect is observed : swelling and hyperemia of the mucous membrane of the eyes.
- The narrowing of the pupil.
- Actively absorbed when applied topically to the general bloodstream, naphazoline hydrochloride can cause a systemic increase in blood pressure.
- Nausea.
- Headache.
- Tachycardia.
Contraindications to the use of drops of "Iridine"
- Increased intraocular pressure, regardless of etiology (glaucoma and other ophthalmic hypertension).
- Arterial hypertension (due to the possibility of developing a systemic side effect in the form of a rise in blood pressure). The use of naphazoline-containing preparations is highly undesirable, regardless of the origin of this symptom.
- Diabetes.
- Hyperthyroidism and thyrotoxicosis.
- Chronic vasomotor rhinitis (especially if the cause of this disease is the previous use of vasoconstrictor drugs).
- The patient's use of drugs from the group of monoamine oxidase inhibitors (you can start using the drops no earlier than ten days after the end of the course of taking such drugs).
- Children's age (medicines containing naphazoline hydrochloride in its composition are contraindicated in patients younger than one year old).
- Infectious and inflammatory processes with localization in the organs of vision.
- Any cases of intolerance or individual hypersensitivity to the components of the drug in the patient's history.
- Diseases of the cardiovascular system.
- There is no data on the excretion of naphazoline hydrochloride with breast milk, so it is strongly recommended to refrain from the use of vasoconstrictors during breast-feeding.
- The drug should not be used to eliminate redness of the eyes with infectious and inflammatory diseases of the eyes.
special instructions
- Under no circumstances should vasoconstrictive eye drops be replaced with nasal preparations that are similar in action, since nasal drops may contain auxiliary ingredients that can adversely affect the structure of the organ of vision. In addition, the concentration of the active substance in nasal preparations is usually higher, which can cause undesirable effects when using such drops as eye drops.
- The use of drops during pregnancy is possible only if absolutely necessary.
- It should be borne in mind that the effect of vasoconstrictor drugs is intermittent. With prolonged systematic use, tolerance to the effect of the drug develops. You can avoid this development by taking breaks in the use of drops every few days (once a week or more often).
- In order to avoid contamination or infection of the contents of the vial, it is necessary to prevent the tip of the vial from touching the surface of the mucous membrane of the eye during instillation.
- It must be remembered which group Iridine belongs to. Drops for eyes, positioned as a cosmetic product, contain a vasoconstrictor component. In order to avoid the development of side effects from the systematic use of this drug should refrain.
- In the presence of any ophthalmic diseases, Iridine eye drops can be used only after consultation and approval of an ophthalmologist. The doctor will be able to draw up a suitable treatment regimen.
- In case of unwanted side effects or other unusual symptoms during therapy, it is necessary to stop using Iridine eye drops. Reviews indicate that side effects occur infrequently, but this situation requires expert advice.
In no case should you self-medicate. Remember that improper use of drugs can only aggravate the situation.
