Dimaz is an ophthalmic medicine without preservatives in the form of sterile drops that contains dorzolamida as the active substance. Dorzolamida belongs to a group of medicines called "carbonic anhydrase inhibitors".

Studies with dorzolamida were carried out in infants and children under 6 years of age diagnosed with glaucoma or high eye pressure (eyes). For detailed information, talk to your doctor, who will decide whether to use this medicine or not.

Elderly patients

In studies with dorzolamida, the effects of this medicine were similar in both elderly and younger patients.

Other medicines andDimaz

3. How to use Dimaz

Follow the instructions for administration of this medicine indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

The appropriate dosage and duration of treatment will be established by your doctor.

If you use Dimaz as the only medicine, the usual dose is one drop in the affected eye(s) three times a day, e.g., in the morning, at noon, and at night.

If your doctor prescribes Dimaz with another medicine to reduce pressure in the eye(s), the usual dose is one drop in the affected eye(s) twice a day, e.g., in the morning and in the evening.

If you use other eye medicines at the same time, keep a 10-minute interval between the administration of these medicines. Ophthalmic ointments should be administered last.

If you need to replace a previous eye drop medicine with Dimaz, stop treatment with the previous medicine (after administration of the recommended dose that day) and start using Dimaz the next day.

Do not change the dosage regimen of Dimaz without consulting your doctor.

Dimaz is a sterile solution that does not contain preservatives. See also Section 6 - Appearance of the product and contents of the pack.

Before instilling the eye drops:

  • When using for the first time, before administering a drop in the eye, first practice using the dropper bottle by slowly squeezing it to administer a drop in the air, away from the eye.
  • When you are confident that you can administer a drop, choose the position that is most comfortable for you to instill the drops (you can sit, lie on your back, or stand in front of a mirror).

Instructions for use:

  1. Wash your hands carefully before using this medicine.
  1. If the box or bottle is damaged, do not use the medicine.
  1. When using the medicine for the first time, you must unscrew the cap after making sure that the tamper-evident ring on the cap has not been broken. You should feel a slight resistance until this tamper-evident ring breaks (see Image 1).
  1. If the tamper-evident ring is loose, it must be discarded because it may fall into the eye and cause injury.
  1. Tilt your head back and gently pull down the lower eyelid to form a pouch between the eye and the eyelid (see Image 2). You should avoid contact between the tip of the bottle and the eyes, eyelids, or fingers to avoid contaminating the solution.
  1. Apply one drop into the pouch by slowly pressing the bottle. Squeeze the bottle gently in the middle and let one drop fall into the eye. There may be a delay of a few seconds between pressing and the drop coming out (see Image 3). Do not squeeze too hard. If you are not sure how to administer this medicine, ask your doctor, pharmacist, or nurse.
  1. Close your eye and press the inner corner of the eye with your finger for about two minutes. This helps prevent the drop from reaching the rest of the body.
  1. Repeat steps 5, 6, and 7 in the other eye if your doctor has indicated so.
  1. After use and before recapping, shake the bottle once downward, without touching the dropper tip, to eliminate any residual liquid on the tip. This is necessary to ensure the delivery of subsequent drops. Screw the cap back onto the bottle after application (see Image 4).

If a drop does not reach the eye, try again.
