1. What is Alcaine and what is it used for
Alcaine contains the active substance proxymetacaine hydrochloride, which has a local anesthetic effect.
Alcaine is used for surface anesthesia before ophthalmic procedures that require rapid and short-term anesthesia, such as: preparation for cataract surgery, removal of corneal sutures, tonometric measurement of intraocular pressure,
gonioscopic examination, removal of foreign bodies, scraping of the conjunctiva for diagnostic purposes, and other procedures if surface anesthesia is necessary.
2. Important information before using Alcaine
When not to use Alcaine
- if the patient is allergic to proxymetacaine hydrochloride or any of the other ingredients of this medicine (listed in section 6),
- without medical supervision,
- for a long time, as this may cause corneal damage, vision loss, and prolonged healing time,
- while wearing contact lenses, as Alcaine contains benzalkonium chloride.
Warnings and precautions
Before starting to use Alcaine, discuss it with your doctor or pharmacist.
- Alcaine is intended for local administration to the eye only by a doctor. It must not be injected.
- The medicine should only be used for eye drops (eyes).
- Repeated use or abuse of this medicine may lead to infections and corneal damage.
- Due to the anesthetic effect, the eyes will lose sensation, so caution should be exercised to avoid accidental eye injury. Do not touch or rub your eyes and take precautions to protect them from everyday contaminants (such as dust, dirt, etc.).
- Repeated use of this medicine may lead to a shortened anesthetic effect.
- Proxymetacaine hydrochloride may cause allergic contact dermatitis. Avoid contact between Alcaine and the skin.
- If other medicines are being used, also read the section Alcaine and other medicines.
- Caution should be exercised when using the medicine in patients:
- with epilepsy, heart disease, hyperthyroidism, or respiratory disorders,
- with myasthenia, as they are particularly sensitive to the effects of local anesthetics,
- with low acetylcholinesterase enzyme activity in blood serum and in patients treated with cholinesterase inhibitors, as there is an increased risk of systemic side effects after local use of local anesthetics from the ester group. Patients should avoid touching or rubbing their eyes until the local anesthetic effect has worn off.
If symptoms of hypersensitivity or irritation occur or worsen, consult a doctor immediately.
Alcaine and other medicines
Tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor before using this medicine.
Using Alcaine during pregnancy and breastfeeding is not recommended.
Driving and using machines
After using Alcaine, temporary blurred vision may occur. Do not drive or operate machines until this symptom has resolved.
Alcaine contains benzalkonium chloride
The medicine contains 0.0035 mg of benzalkonium chloride per drop, which corresponds to 0.1 mg/ml.
Benzalkonium chloride may be absorbed by soft contact lenses and change their color. Remove contact lenses before instillation and wait at least 15 minutes before reinserting. Benzalkonium chloride may also cause eye irritation, especially in people with dry eye syndrome or corneal disorders (the transparent layer at the front of the eye). If abnormal sensations, stinging, or eye pain occur after using the medicine, consult a doctor.
3. How to use Alcaine
Alcaine is intended for use by a doctor only.
Recommended dose
When preparing a patient for a simple examination, e.g., tonometric examination or other short-term procedures, usually one to two drops are instilled directly before the procedure.
Before minor surgical procedures, such as removal of a foreign body or sutures, instill one to two drops every five to ten minutes, one to three times.
To achieve long-term anesthesia, e.g., during cataract surgery, instill one to two drops of the medicine into the eye (eyes) every five to ten minutes, three to five times.
Remember that the local anesthetic effect occurs within 30 seconds and may last up to 15 minutes.
Method of administration
Alcaine should only be instilled into the eye (eyes).
Remove the cap. If the protective collar is loose after removing the cap, discard it before using the medicine.
To prevent infection of the dropper tip or solution, be careful not to touch the dropper tip to the eyelids or surrounding tissues. Keep the bottle tightly closed when not in use.
Systemic absorption of the medicine can be reduced by using the following methods after instillation:
- close your eyes for 2 minutes;
- press the nasolacrimal duct with your finger for 2 minutes.
Do not use the solution if it is cloudy or has changed color.
Note: Since there is no blinking reflex after using the medicine, it is recommended to apply an eye patch after the procedure.
If the patient is using other eye drops or ointments at the same time,wait at least 5 minutes between administrations of the next medicines. Apply eye ointments last.
Using a higher dose of Alcaine than recommended
If a higher dose than recommended is used, flush the eye with lukewarm water.
In case of overdose or accidental ingestion, consult a doctor, pharmacist, or poison control center immediately, as severe reactions from the nervous or respiratory system may occur.
Missing a dose of Alcaine
Do not double the dose to make up for a missed dose.
If you have any further doubts about using this medicine, consult your doctor or pharmacist.
4. Possible side effects
Like all medicines, Alcaine can cause side effects, although not everybody gets them.
The following side effects have been observed with the use of Alcaine, but their frequency cannot be estimated from the available data:
- Eye-related effects: corneal damage, clouding of the eye surface, swelling of the eye surface, inflammation of the eye surface, blurred vision, photophobia, pupil dilation, eye pain, eye irritation, eye swelling, discomfort in the eye, redness of the eye, increased tear production.
- General side effects: hypersensitivity (allergy), fainting, dizziness. Transient symptoms, such as a feeling of stinging, burning, or redness of the conjunctiva, may occur. In rare cases, an allergic reaction of the cornea (in which acute, diffuse corneal epithelial inflammation with the formation of fibers and (or) separation of large areas of necrosis, diffuse edema of the substrate, inflammation of the posterior limiting layer, and inflammation of the iris) may occur.
In very rare cases, after local use in the eye, systemic toxic effects may occur, manifested by central nervous system stimulation, followed by its depression.
Additionally, uncontrolled use or abuse of Alcaine may lead to permanent corneal disorders and (or) eye damage.
