How to use Mydriacyl correctly

If the safety collar is loose when the cover has been removed, it must be removed before using the product.

  1. Take out the bottle of Mydriacyl.
  2. Wash your hands and sit in front of a mirror.
  3. Turn off the bottle cap.
  4. Hold the bottle with the tip down between your thumb and forefinger (picture 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. Bring the tip of the bottle towards the eye. Use a mirror if it makes it easier.
  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 Mydriacyl at a time (Figure 3).
  10. After using Mydriacyl, close the eyelid and gently press with a finger into the inner corner of the eye for 2 minutes (Fig. 4). It prevents Mydriacyl from reaching other parts of the body.
  11. If you are using Mydriacyl in both eyes, repeat steps 4 through 10 for the other eye.
  12. Tighten the bottle cap carefully immediately after use.

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

If you use other eye drops or ointments, wait at least 5 minutes between using the medicines. Eye ointments should be used last.

If you use more Mydriacyl than you should

If you have used too much Mydriacyl, rinse everything out with lukewarm water. Do not drip in a few more drops until it is time for your next regular dose.

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

If you forget to use Mydriacyl

Continue with the next dose as planned. However, if it is almost time for your next dose, you can skip the missed dose and return to your regular dosing schedule.

Do not take a double dose to make up for a forgotten dose.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
