Important information if you wear Contact Lenses

Wearing contact lenses is not advisable during the treatment of an eye infection, as they may make your condition worse. Do not use the drops while wearing contact lenses. Wait at least 15 minutes after use before putting your lenses back in. There is a preservative in MAXITROL (benzalkonium chloride) that can discolour soft contact lenses.


The usual dose

The usual dose is 1 or 2 drops into the space between your eyelid and eye 6 times daily, or more frequently if required.

Remove the loose collar from the cap when the bottle is first opened.

Always use MAXITROL exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

MAXITROL should not be used for a long period of time unless advised by your doctor.

  • Twist off the bottle cap.
  • Hold the bottle pointing down, between your thumb and fingers.
  • Tilt your head back.
  • Pull down your lower eyelid with a finger, until there is a pocket1 between the eyelid and your eye. The drop will go in here (picture 1).

  • If a drop misses your eye, try again.
