PROPER USE OF THIS MEDICATION

Usual adult and child (6 years and older) dose:

Apply 1 drop to the eye(s). If necessary, apply a second drop 5 minutes later.

How to use:

1 2 3 Before you start:

• Get the CYCLOGYL^* bottle and a mirror.
• Wash your hands.
• Twist off the bottle cap.

• After cap is removed: if security snap collar is loose,

  remove before using product.

Applying a drop:

• Hold the bottle, pointing down, between your thumb and

  fingers.

• Tilt your head back.

• Pull down your lower eyelid with a clean finger until

  there is a ‘pocket’ between your eyelid and your eye. The drop will go in here (picture 1).

• Bring the bottle tip close to the eye. Do this in front of a

  mirror if it helps.

• Do not touch your eye or eyelid, surrounding areas or

  other surfaces with the dropper. It could infect the drops.

• Gently press on the base of the bottle to release one drop

  of CYCLOGYL^* at a time.

• Do not squeeze the bottle. It is designed so that a gentle

  press on the bottom of the bottle is all that it needs (picture 2).

• After a drop has been put into the eye, press a finger into

  the corner of your eye by the nose (picture 3). This helps to keep the drop in the eye.

• If you use drops in both eyes, repeat the steps for your

  other eye.

• If a drop misses your eye, try again.

After use:

• Close the bottle cap firmly immediately after use.

• Wash your hands (and your child’s hands, mouth and

  cheeks).
