User instructions
  1. Bring out the bottle of Isopto-Atropine.
  2. Wash your hands and sit in front of a mirror.
  3. Unscrew the cap on the bottle.
  4. Hold the bottle facing down between your thumb and forefinger (Fig. 1).
  5. Tilt your head back. Pull down the lower eyelid with a clean finger, until a “pocket” is formed between the lower eyelid and the eye. This is where the drop should be placed.
  6. Move the bottle tip close to the eye. Use a mirror if it helps.
  7. Avoid touching the eye or eyelid, surrounding areas or other surfaces with the drip tip. It may contaminate the eye drops in the bottle.
  8. Do not squeeze the bottle. It is designed so that a light pressure on the bottom is all that is needed (Fig. 2).
  9. Gently press on the bottom of the bottle to release one drop of Isopto-Atropine at a time (Figure 3).
  10. After using Isopto-Atropine, close the eyelid and gently press with a finger in the corner of the eye at the nose for 2 minutes (Fig. 4). It helps prevent Isopto-Atropine from entering the rest of the body.
  11. If you are using Isopto-Atropine in both eyes, repeat steps 5 through 10 for your other eye.
  12. Tighten the bottle cap firmly immediately after use.

If a drop misses the eye, wipe it off immediately and try again.

If you are taking other medicines in the form of eye drops or eye ointments, wait at least 5 minutes between each use of the medicine. Eye ointments should be used last.

If you use more Isopto-Atropine than you should

If you have ingested too much medicine or if e.g. If a child has ingested the medicine by mistake, contact a doctor, hospital or the Poison Information Center for risk assessment and advice.

If you have used too much Isopto-Atropine, rinse everything out with warm water. Do not drip in more drops until it is time for the next scheduled dose .

Symptoms of overdose may include: redness and dry skin (children may get a rash), blurred vision, rapid and irregular heartbeat , fever, bloated abdomen in infants, seizures, hallucinations or loss of coordination.

If you forget to use Isopto-Atropine
