special instructions
Alcaine can only be used topically, it is not intended for injection.
After the end of the surgical procedure, you need to cover the eye with a bandage, since the blink reflex is briefly eliminated.
When using Alkain, the use of contact lenses is not recommended.
Long-term therapy can reduce the duration of the effect, and therefore an increase in the amount of the drug may be required to achieve the desired anesthetic effect.
During the entire period of anesthesia, it is necessary to protect the eye from the ingress of foreign bodies, irritating substances into it, and also to rub the eye until the end of the anesthetic effect.
If symptoms of eye irritation or hypersensitivity develop, the drug should be discontinued.
The bottle should be closed after each use. Do not touch the eye with the pipette tip.
If after using Alcaine there is a short blurring of vision, it is not recommended to drive vehicles and perform work that requires an increased reaction and concentration until it is restored.
