Eye drops are aqueous (oily) solutions or the thinnest suspensions of drugs. These medicines have high requirements for sterility and stability. Eye drops should not have in their composition mechanical impurities visible to the naked eye.
Due to the fact that the solvent in the composition of the preparations is usually water, their therapeutic effect does not differ in duration. This, in turn, raises the need for more frequent installations. As a result, an allergy to drugs can occur and the likelihood of infection increases. However, many eye drops contain substances that increase their viscosity. Such drugs have a longer effect.
Only a doctor can prescribe eye drops for the prevention or treatment of any ophthalmic diseases . The independent use of medicines may not have the intended effect, and in some cases, significantly harm. It is also not recommended to replace the prescribed drugs with analogues without the recommendation of a doctor.
When prescribing two or more ophthalmic preparations, it is necessary to take breaks (fifteen to twenty minutes or as directed by a doctor) between instillation of different medications.
Keep eye drops strictly in accordance with the information specified in the instructions. The annotation to any drug, including ophthalmic, contains information about the shelf life of the medication. As a rule, it is two years for a non-open bottle and a month for an open one. Expired medicines cannot be used.
Wash your hands immediately before using an ophthalmic drug. It should be noted that when using drops, there is a risk of an infection in the eyes (just accidentally touching the tip of the bottle to your fingers, eyelid or any surface). Before use, it is recommended that the drug be slightly warmed up. Since ophthalmic preparations are stored in the refrigerator, they have an appropriate temperature. Cold drops have low absorption and may cause irritation. The drug should be heated in a cup with hot water or under the tap, but in no case in the microwave. Contact lenses should be removed before instilling. You can install them back after fifteen to twenty minutes after applying the medication.
In no case can you use someone else's ophthalmic drugs and give someone your own. These drugs are strictly individual.
Ophthalmic preparations can be prescribed for eye fatigue, allergies, viruses, and inflammations. Drops can be vitamin, antibacterial, vasoconstrictor, for the treatment of ophthalmic diseases. In many cases, medicines are also used for diagnostic purposes. For example, drops to dilate the pupils. The duration of action of such drugs can be short (from several hours to several days) and long (up to several weeks).
Ophthalmic diseases are characteristic not only for humans. In animals (dogs, cats) there is both conjunctivitis and rhinitis. Anandine (eye drops) are used in veterinary medicine. The drug has antimicrobial, anti-inflammatory, regenerative and antiviral effects. Available in the form of a clear light green liquid in a bottle of five milliliters. When using the medication, local irritating and allergic reactions do not occur. The use of the drug is considered the most effective in the initial stages of the disease.
