Visual impairment is a serious problem. At the first symptoms it is worth visiting an optometrist. The specialist will conduct a series of tests and make an accurate diagnosis. The sooner treatment is started, the more likely it is to maintain eye health. First of all, topical medications are prescribed. Many problems associated with ophthalmology are solved using Irifrin drops. Analogs can also be used on the recommendation of a specialist.
The composition of the drug and its release form
The medicine is offered in pharmacies in the form of a liquid solution. Phenylephrine hydrochloride is the basis of the drug. One ampoule may contain 25 and 100 mg of this component. As auxiliary components, benzalkonium chloride, hypromellose, disodium edetate, sodium metabisulfite, citric acid, and also purified water are used.
The drug belongs to the group of sympathomimetics. The use in the dosage prescribed by the doctor does not affect the functioning of the central nervous system. The main active ingredient contributes to the expansion of the pupil. In addition, the vessels of the conjunctiva are narrowed. Thanks to this, it is possible to quickly remove the unpleasant symptoms of many eye diseases. It is worth noting that Irifrin eye drops cannot be used as monotherapy. Analogs also can not cope with the disease. The medicine helps to eliminate the symptoms, but does not affect the development of the disease.
Indications
First of all, the medication is used to prevent the development of posterior synechia, as well as to reduce exudation from the iris. With the help of drops, iridocyclitis therapy can be carried out. They can also be prescribed in ophthalmology as an auxiliary agent drops “Irifrin”. Analogs are also used as directed by a specialist. Using phenylephrine-based preparations, a diagnostic expansion of the pupil is performed. Thus, it turns out to conduct a complete examination of the posterior segment of the eyeball. In patients who have a narrow angle of the anterior chamber of the eye or angle-closure glaucoma, a provocative test is complicated. The problem is also solved with the help of the drug "Irifrin."
In ophthalmic surgery, drops of 10% are most often used. With their help, preoperative preparation of the
eyes, expansion of the pupil, and deep injection of the eyeball are performed. If it is necessary to carry out procedures using a laser, the drug is also used as a preparatory tool.
At home, Irifrin 2.5 eye drops are used. Analogs are also used to eliminate symptoms such as redness of the eyes and burning. The medicine quickly helps restore vision after prolonged use in front of a computer monitor. In addition, the drug is used to treat glaucoma-cyclical crises, as well as accommodation spasm. But you should not use the drug without consulting an ophthalmologist or ophthalmologist. Only after making an accurate diagnosis and conducting a series of tests can you be sure that the drops will be useful. The problem is that the medication also has many contraindications. In order to avoid the development of side effects, you should first consult with your doctor.
Contraindications
With closed-angle or narrow-angle glaucoma, Irifrin drops cannot be used. Analogs should be used only after examination by a qualified specialist. With caution, the drug is prescribed to the elderly, as well as patients who have circulatory system malfunctions. Medication can help worsen cerebral circulation. If the patient has a violation of the integrity of the eyeball, drops can not be used before surgery to expand the pupil. In this case, preparation before surgery is conducted in a more gentle way.

Do not prescribe it only to premature infants. Drops "Irifrin" 10% is prescribed only to adult patients.
special instructions
Patients who suffer from diabetes can use the drug only under the supervision of a doctor. There is a risk of increased intracranial pressure. This is due to a violation of autonomic regulation. The same restrictions apply to elderly patients (over 70 years old).
With caution, drops should be used in conjunction with MAO inhibitors. It is advisable to exclude such a combination altogether. It is recommended to start treatment with the drug only three weeks after the end of the intake of inhibitors.
You can not increase the recommended dose of the drug "Irifrin." Instructions for use, reviews, analogues and release forms - all this must be clarified by the doctor before the start of therapy. This is especially true for patients who have a violation of the integrity of the lining of the eyes. Exceeding the recommended doses increases the absorption of phenylephrine. As a result, systemic side effects develop.
Dosage
In the preparation for surgical intervention drops "Irifrin" are used once. To achieve the maximum positive effect in the conjunctival sac, it is enough to introduce one drop of the drug. A specialist can begin work only an hour after the administration of the medication. The effect persists for several hours. If the operation is long, the drops are reintroduced.
If it is necessary to carry out diagnostics to dilate the pupil in adults and children over 10 years old, the Irifrin 10% agent can be used. The dosage used is the same (one drop in each conjunctival sac).
In case of accommodation spasm, Irifrin (eye drops) is also used. The doctor will tell you the analogs if there was no suitable product in the pharmacy. Patients over 6 years of age are prescribed one drop of the drug in each eye at night. The course of treatment can last no more than 4 weeks. If no dynamics are observed in the second week of therapy, the doctor may adjust the dosage. At the initial stage, Irifrin drops of 2.5% are used.
Phenylephrine helps reduce intraocular pressure. This effect is used in the treatment of glaucoma-cyclical crises. Most commonly used are 10 percent drops. The drug is instilled 2-3 times a day. In this case, therapy can be carried out only for patients older than 10 years. In young children, the problem is eliminated with the help of other medicines.
Side effects
To maintain health, it is worth taking Irifrin (drops) correctly. Instructions for use, reviews, descriptions, analogues - all this is worth exploring before starting treatment. A medicine can have many side effects. Most often they are manifested by the organs of vision. In patients at the initial stage of treatment, conjunctivitis or periorbital edema may develop. The patient feels a burning sensation in the corners of the eyes. Such an unkempt symptom is temporary and does not require withdrawal of the drug.
Elderly patients 12 hours after using the drops may notice reactive myosis. With repeated instillations, this effect is no longer observed. Most often, this phenomenon is observed not only when using the drug "Irifrin". Cheaper analogues often have the same effect.
There may be side effects from the circulatory system. Patients may experience palpitations, arrhythmia, tachycardia, pulmonary embolism, reflex bradycardia. If the patient’s well-being does not significantly deteriorate, it makes no sense to cancel the Irifrin medicine. Analogs and substitutes for the drug may have the same effect on the patient's body.
In rare cases, allergic reactions caused by hypersensitivity develop. Most often, contact dermatitis develops. The problem is quickly eliminated by taking antihistamines.
Drug interaction
It should be borne in mind that the effect of taking the drug "Irifrin" is enhanced when used in conjunction with atropine. Perhaps the development of side effects from the cardiovascular system. The combined use of drops with MAO inhibitors can lead to a significant increase in pressure. The risk of side effects also remains for three weeks after the end of therapy with inhibitors. An ophthalmologist should always check with the patient for information on previously taken medications.
It is not necessary to use the drug "Irifrin" 10% together with beta-blockers. Such an interaction can lead to acute hypertension.
Phenylephrine drops are not used with inhalation anesthesia. This component can contribute to the inhibition of the cardiovascular system. During prolonged operations, the risk of heart failure increases. Therefore, the drug is used with caution in complex surgical interventions.
Analogues of the drug
It is not always possible to find the necessary drug in the pharmacy. Irifrin drops are no exception. Analogs, price, instructions for use - a specialist in an ophthalmic clinic will tell about all this. Doctors often recommend the use of Tropicamide drops. This low-cost drug copes with many eye diseases. Its cost in pharmacies is only 60-70 rubles. As auxiliary substances in drops, disodium edetate dihydrate, benzalkonium chloride, sodium chloride, hydrochloric acid, and also purified water are used in drops. The drug has virtually no contraindications. Do not prescribe it only to patients with glaucoma. The medicine can be used during pregnancy and lactation. Infants are prescribed after consultation with a pediatrician.
