1. What Vizidor Duo is and what it is used for

Vizidor Duo 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 lower pressure in the eye in different ways.

Vizidor Duo is prescribed to lower raised pressure in the eye in the treatment of glaucoma when beta-blocker eyedrop medicine used alone is not adequate.

Vizidor Duo eye drops solution is a sterile solution that does not contain a preservative.

2. What you need to know before you use Vizidor Duo

Do not use Vizidor Duo

  • if you are allergic to dorzolamide, timolol or any of the other ingredients of this medicine (listed in section 6);
  • if you have now or had in the past respiratory problems, such as asthma or severe chronic obstructive bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing and/or long-standing cough);
  • if you have a slow heartbeat, heart failure or disorders of heart rhythm (irregular heartbeats);
  • if you have severe kidney disease or problems, or a prior history of kidney stones;
  • if you have excess acidity of the blood caused by a buildup of chloride in the blood (hyperchloraemic acidosis).

If you are not sure whether you should use this medicine, contact your doctor or pharmacist.

Warnings and precautions

Talk to your doctor before using Vizidor Duo Tell your doctor about any medical or eye problems you have now or have had in the past, such as:

  • coronary heart disease (symptoms can include chest pain or tightness, breathlessness, or choking), heart failure, low blood pressure;
  • disturbances of heart rate such as slow heart beat;
  • breathing problems, asthma or chronic obstructive pulmonary disease;
  • poor blood circulation disease (such as Raynaud’s disease or Raynaud’s syndrome);
  • diabetes, as timolol may mask signs and symptoms of low blood sugar;
  • overactivity of the thyroid gland, as timolol may mask signs and symptoms.

If you have a history of contact hypersensitivity to silver, you should not use this product.

Tell your doctor before you have an operation that you are using Vizidor Duo, as timolol may change effects of some medicines used during anaesthesia.

Also tell your doctor about any allergies or anaphylactic reactions including hives, swelling of the face, lips, tongue, and/or throat which may cause difficulty in breathing or swallowing. Tell your doctor if you have muscle weakness or have been diagnosed as having myasthenia gravis.

If you develop any eye irritation or any new eye problems such as redness of the eye or swelling of the eyelids, contact your doctor immediately. If you suspect that Vizidor Duo is causing an allergic reaction or hypersensitivity (for example, skin rash, severe skin reaction, or redness and itching of the eye), stop using this medicine and contact your doctor immediately.

Tell your doctor if you develop an eye infection, receive an eye injury, have eye surgery, or develop a reaction including new or worsening symptoms.

When Vizidor Duo is instilled into the eye, it may affect the entire body.

Vizidor Duo has not been studied in patients wearing contact lenses. If you wear soft contact lenses, you should consult your doctor before using this medicine.

Children

There is limited experience with Vizidor Duo (preserved formulation) in infants and children.

Elderly

In studies with Vizidor Duo (preserved formulation), the effects of Vizidor Duo (preserved formulation) were similar in both elderly and younger patients.

Use in patients with liver impairment

Tell your doctor about any liver problems you have now or have suffered from in the past.

Other medicines and Vizidor Duo

Vizidor Duo can affect or be affected by other medicines you are using, including other eye drops for the treatment of glaucoma. Tell your doctor if you are using or intend to use medicines to lower blood pressure, heart medicine or medicines to treat diabetes.

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

This is particularly important if you are:

  • taking medicine to lower blood pressure or to treat heart disease (such as calcium channel blockers, beta-blockers or digoxin);
  • taking medicines to treat a disturbed or irregular heartbeat such as calcium channel blockers, beta-blockers or digoxin;
  • using another eye drop that contains a beta-blocker;
  • taking another carbonic anhydrase inhibitor such as acetazolamide;
  • taking monoamine oxidase inhibitors (MAOIs);
  • taking a parasympathomimetic medicine which may have been prescribed to help you pass urine. Parasympathomimetics are also a particular type of medicine which is sometimes used to help restore normal movements through the bowel;
  • taking narcotics such as morphine used to treat moderate to severe pain;
  • taking medicines to treat diabetes;
  • taking antidepressants known as fluoxetine and paroxetine;
  • taking a sulfa medicine;
  • taking quinidine (used to treat heart conditions and some types of malaria).

Pregnancy and breast-feeding

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

Use in pregnancy

You should not use Vizidor Duo if you are pregnant unless your doctor considers it necessary.

Use in breast-feeding

You should not use Vizidor Duo if you are breast-feeding. Timolol may get into your milk.

Driving and using machines

No studies on the effects on the ability to drive or use machines have been performed. There are side effects associated with Vizidor Duo, such as blurred vision, which 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 Vizidor Duo

Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The appropriate dosage and duration of treatment will be established by your doctor.

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

If you are using Vizidor Duo with another eye drop, the drops should be instilled at least 10 minutes apart.

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

If you have difficulty administering your eye drops, seek the assistance of a family member or carer.

Do not allow the tip of the multi dose container to touch the eye or areas around the eye. It could cause injury to your eye. The eye drops solution may become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the multi-dose container, keep the tip of the multi-dose container away from contact with any surface.

Instructions for use

Before instillation of the eye drops:

  • Wash your hands before opening the bottle.
  • Do not use this medicine if you notice that the tamper-proof seal on the bottle neck is broken before you first use it.
  • When using for the first time, before delivering a drop to the eye, you should first of all practise using the dropper bottle by squeezing it slowly to deliver one drop into the air, away from the eye.
  • When you are confident that you can deliver one drop at a time, choose the position that you find most comfortable for the instillation of the drops (you can sit down, lie on your back, or stand in front of a mirror).

Instillation:

1. Hold the bottle directly below the cap and turn the cap to open the bottle. Do not touch anything with the tip of the bottle to avoid contamination of the solution.

2. Tilt your head backwards and hold the bottle above your eye.

3. Pull the lower eyelid down and look up. Squeeze the bottle gently in the middle and let a drop fall into your eye. Please note that there might be a few seconds delay between squeezing and the drop coming out. Do not squeeze too hard.

If you are not sure how to administer your medicine, ask your doctor, pharmacist or nurse.

4. Blink a few times so that the drop spreads over the eye.

5. Repeat the instructions 2. – 4. to deliver a drop into the other eye also, if your doctor has instructed you to do this. Sometimes only one eye needs to be treated and your doctor will advise if this applies to you and which eye needs treatment.

6. After use and prior to recapping, the bottle should be shaken once in a downwards direction, without touching the dropper tip, in order to remove any residual liquid on the tip. This is necessary in order to ensure delivery of subsequent drops.

7. After you have used all doses there will be some Vizidor Duo left in the bottle. You should not be concerned since an extra amount of Vizidor Duo has been added and you will get the full amount of Vizidor Duo that your doctor has prescribed. Do not attempt to use the excess medicine remaining in the bottle after you have completed the course of treatment.

Do not use the eye drops for longer than 28 days after first opening the bottle.

If you use more Vizidor Duo than you should

If you put too many drops in your eye or swallow any of the contents of the container, among other effects, you may become light-headed, have difficulty breathing, or feel that your heart rate has slowed. Contact your doctor immediately.

If you forget to use Vizidor Duo

It is important to take Vizidor Duo as prescribed by your doctor.

If you miss a dose, use it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule.

Do not takea double dose to make up for the forgotten dose.

If you stop using Vizidor Duo

If you want to stop using this medicine talk to your doctor first.

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

4. Possible side effects
