1. WHAT MIPHTEL IS AND WHAT IT IS USED FOR
The active substance in MIPHTEL 20 mg powder and solvent for solution for intraocular irrigation
is acetylcholine chloride. It belongs to a group of substances called parasympathomimetics
(neurohormones) involved with the transmission of nerve impulses in the body.
MIPHTEL is used during cataract surgery and other types of eye surgery to make the pupil (at the front of
the eye) contract. This helps the surgeon carry out the surgical procedure.
If you have any questions about how MIPHTEL works or why this medicine has been prescribed for you,
ask your doctor or the medical staff looking after you.
It is available only for hospital use.
NOTE: This is a patient information leaflet. Doctors and other health professionals involved in the administration
of MIPHTEL should consult the administration instructions for healthcare professionals before use.

disturbances have subsided.
3. HOW MIPHTEL IS GIVEN
This medicine will be given to you only by the surgeon. Your surgeon will work out the correct dose of
MIPHTEL for you. In most cases 0.5 ml to 2 ml of solution is a suitable dose.
The solution should be made up just before it is given for intraocular use (i.e. use in the eye). It
contains 10mg/ml of acetylcholine chloride (20mg/2ml).
Each ampoule of powder and solvent is for single use only.
If too much is given
If you are given more medicine than you need, your doctor may need to give you an injection of either
atropine sulphate or adrenaline to control symptoms. Symptoms of overdose may include slow heart rate,
low blood pressure, flushing, breathing difficulties and sweating. Because acetylcholine is rapidly broken
down by the body, symptoms of overdose are unlikely to occur.

may be made.
