Vizin Drops are manufactured by renowned Canadian company Keata Pharma Ink. The active substance in them is tetrizoline. In addition to this tool, it is part of the eye and nasal drops "Octilia", "Montevizin", "Berberyl N", "Tizin", "Visoptin" and others. This substance belongs to the class of alpha-adrenergic agonists that provide local vasoconstrictor action and effectively relieve swelling of the mucosa. Its advantage lies in the fact that the effect of its use occurs almost immediately, after a couple of minutes, and persists after that quite a long time (up to eight hours).
Tetrizolin is used in the treatment of rhinitis, conjunctival irritation, allergic conjunctivitis. So, Vizin eye drops, the instructions for which contain a list of indications for their use, are successfully used to eliminate hyperemia (redness) of the mucous membrane of the eyes. They stop lacrimation and relieve swelling, help reduce the formation of intraocular fluid. Vizin drops (the instructions describe their properties) completely eliminate the irritation of the mucous membrane of the eyes caused by the action of bright light, polluted air or water. They effectively cope with allergy symptoms, manifested, for example, as a result of the use of poor-quality cosmetics or due to seasonal exacerbation of the disease.
You should pay attention to contraindications to the use of this tool. So, Vizin eye drops (the instruction emphasizes this) cannot be used to treat children under two years of age. Their use during pregnancy is also undesirable. With coronary heart disease, high blood pressure, hyperthyroidism and diabetes, this remedy must be used very carefully. It should also be borne in mind that individual intolerance to tetrizoline is possible, manifested by a burning sensation and pain in the eyes, as well as an intensification of those symptoms that the drops were intended to eliminate - eye irritation and conjunctival redness.
Eye drops "Vizin" instruction recommends using 2-3 times a day, 1-2 drops. Before that, contact lenses must be removed. If there is no improvement within two days, you should seek the advice of a doctor. In any case, it is not worth dripping them for more than four days: after all, tetrizoline only relieves unpleasant symptoms, but does not treat the disease that caused them.
Not so long ago, the Vizin Pure Teardrop drops, produced by one of the French companies, appeared in the line of drugs of the same name. Unlike the classic drug "Vizin", this tool does not dry, but, on the contrary, moisturizes the mucous membrane of the eyes - this is its main function. Drops contain a patented solution that is close in composition to human tears - it contains natural plant extracts. This tool can be recommended for those who often suffer from dry eyes caused by long reading, working at a computer, driving a car. Use it three to four times a day, one or two drops. After instillation, it is advisable to blink to evenly distribute the liquid on the surface of the eye.
Before using this drug, it is not necessary to remove contact lenses: Vizin Pure Tear drops will not harm them. However, with all the harmlessness of this tool, its individual intolerance is not excluded: it can be manifested by a feeling of discomfort and burning, redness of the mucous membrane and swelling of the eyelids. In this case, the use of the drug should be discontinued and consult a doctor. In order to avoid complications, other ophthalmic agents should not be used at the same time - in particular, the classic Vizin eye drops: the instruction warns that the drug in this case can change its effect.
