1. What is Tidimaz and what is it used for

Tidimaz is a sterile solution without preservatives that contains two medicines: dorzolamide and timolol.

  • Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors".
  • Timolol belongs to a group of medicines called "beta-blockers".

These medicines reduce pressure in the eye in different ways.

Tidimaz is prescribed to reduce high pressure in the eye in the treatment of glaucoma when the use of a single beta-blocker eye drop is not appropriate.

2. What you need to know before you use Tidimaz

Do not useTidimaz

  • if you are allergic to dorzolamide hydrochloride, timolol maleate, or any of the other ingredients of this medicine (listed in section 6).
  • if you have now or have had in the past respiratory problems, such as asthma or severe chronic obstructive pulmonary disease (severe lung disease that can cause wheezing, difficulty breathing, and/or persistent cough over a long time).
  • if you have a slow heart rate, heart failure, or heart rhythm disturbances (irregular heartbeats).
  • if you have severe kidney disease or a history of kidney stones.
  • if you have excess acidity in the blood caused by an accumulation of chloride in the blood (hyperchloremic acidosis).

If you are not sure whether you should use Tidimaz, consult your doctor or pharmacist.

Warnings and Precautions

Consult your doctor before starting to use Tidimaz.

Tell your doctor about any medical or eye problems you have now or have had in the past, especially if you have:

  • respiratory or lung problems, asthma, or chronic obstructive pulmonary disease.
  • coronary heart disease (symptoms may include chest pain or tightness, difficulty breathing, or shortness of breath), heart failure, low blood pressure.
  • heart rhythm disturbances such as a slow heart rate.
  • circulatory problems (such as Raynaud's disease or Raynaud's syndrome).
  • diabetes, as timolol may mask signs and symptoms of low blood sugar levels.
  • thyroid problems, i.e., overactivity of the thyroid gland, as timolol may mask signs and symptoms.
  • liver problems.
  • any allergy or allergic reaction, including hives, swelling of the face, lips, tongue, and/or throat that can cause difficulty breathing or swallowing.
  • muscle weakness or if you have been diagnosed with myasthenia gravis.

If you experience any of the following symptoms, stop usingthe eye drops and contact your doctor immediately:

  • any eye irritation or any new eye problem, such as redness of the eyes or swelling of the eyelids, contact your doctor immediately.
  • symptoms of an allergic reaction. See section 4 "Possible side effects" (e.g., skin rash or redness and itching of the eyes).

Tell your doctor that you are using Tidimaz if you have an eye injury or are going to have eye surgery, as timolol may affect the effects of some medicines used during anesthesia.

When Tidimaz is instilled in the eye, it can affect the whole body.

Tidimaz has not been studied in patients who use contact lenses. If you use soft contact lenses, you should consult your doctor before using Tidimaz. Before instilling this medicine, remove your contact lenses and reapply them after at least 15 minutes from instillation.

Children

There is limited experience with dorzolamide hydrochloride and timolol in infants and children.

Elderly Patients

In studies with dorzolamide hydrochloride and timolol with preservatives, the effects were similar in both elderly and younger patients.

Other Medicines and Tidimaz

Tidimaz may affect or be affected by other medicines you are using.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including other eye drops or those bought without a prescription. This is especially important if you are taking:

  • medicines to lower blood pressure or to treat heart diseases (such as calcium channel blockers, beta-blockers, or digoxin).
  • medicines to treat an irregular heartbeat, such as calcium channel blockers, beta-blockers, or digoxin.
  • monoamine oxidase inhibitors (MAOIs) used to treat depression.
  • parasympathomimetic medicine that may have been prescribed to help you urinate. Parasympathomimetics are also a particular group of medicine that is sometimes used to help restore normal movement through the intestine.
  • opioids such as morphine used to treat moderate to severe pain.
  • medicines to treat diabetes.
  • antidepressants known as fluoxetine and paroxetine.
  • medicines with sulfonamide.
  • quinidine (used to treat heart diseases and some types of malaria).
  • other eye drops that also contain a beta-blocker or other carbonic anhydrase inhibitors like acetazolamide.

Athletes:

This medicine contains timolol, which may produce a positive result in doping tests.

Pregnancy and Breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

Do not use Tidimaz if you are pregnant. Tell your doctor if you are pregnant or planning to become pregnant.

Breastfeeding

Timolol may pass into breast milk. If treatment with Tidimaz is required, breastfeeding is not recommended. Tell your doctor if you are breastfeeding or planning to breastfeed.

Driving and Using Machines

No studies on the effects on the ability to drive and use machines have been performed. There are side effects associated with Tidimaz, such as blurred vision, that may affect your ability to drive and/or operate machinery. Do not drive or operate machinery until you feel well or your vision is clear.

3. How to Use Tidimaz

Follow the instructions for administration of this medicine exactly as told by your doctor. If you are not sure, consult your doctor or pharmacist again.

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

The recommended dose is one drop in the affected eye(s) in the morning and at night.

If you are using Tidimaz at the same time as another eye drop, the drops should be instilled at least 10 minutes apart. Ophthalmic ointments should be administered last.

Do not change the dose of the medicine without consulting your doctor.

Tidimaz 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 squeezing it slowly 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 you find most comfortable for instilling 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.
  2. If the carton or bottle is damaged, you should not use the medicine.
  3. 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 the tamper-evident ring breaks (see Image 1).
  4. If the tamper-evident ring is loose, it should be discarded because it may fall into the eye and cause injury.
  5. Tilt your head back and gently pull down the lower eyelid to form a pocket 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.
  6. Apply one drop into the pocket by gently squeezing 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 compression and the drop coming out (see Image 3). Do not squeeze too hard. If you are not sure how to administer this medicine, you should ask your doctor, pharmacist, or nurse.
  7. 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.
  8. Repeat steps 5, 6, and 7 in the other eye if your doctor has told you to do so.
  9. After use and before closing, shake the bottle once downwards without touching the dropper tip to remove any residual liquid from the tip. This is necessary to ensure the administration of subsequent drops. Screw the cap back on the bottle after application (see Image 4).

If a drop misses the eye, try again.
