1. Package contents and further information

1. What is Cosduo and what is it used for

Cosduo contains two active substances: dorzolamida and timolol.

• Dorzolamida belongs to a group of medicines called “carbonic anhydrase inhibitors”.
• Timolol belongs to a group of medicines called “beta-blockers”.

These medicines reduce eye pressure in different ways.

Cosduo is prescribed to reduce pressure in the eye in the treatment of glaucoma when the use of a beta-blocker eye drop on its own is not appropriate.

Cosduo eye drops, solution is a sterile solution that does not contain preservatives.

2. What you need to know before you use Cosduo

Do not use Cosduo

• if you are allergic to dorzolamida, timolol 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 may cause wheezing, difficulty breathing and/or prolonged coughing);
• if you have a slow heart rate, heart failure or irregular heart rhythms (irregular heartbeats);
• if you suffer from severe kidney disease or kidney stone problems;
• if you have excess acidity of the blood caused by an accumulation of chlorides in the blood (hyperchloremic acidosis).

If you are not sure if you should use this medicine, consult your doctor or pharmacist.

Warnings and precautions

Consult your doctor or pharmacist before you start using Cosduo.

Tell your doctor about any current or past medical or eye problems, such as:

• coronary heart disease (symptoms may include chest pain or tightness, difficulty breathing, or shortness of breath), heart failure, low blood pressure;
• irregular heart rhythms such as decreased heart rate;
• respiratory problems, asthma or chronic obstructive pulmonary disease;
• poor circulation (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 medicine as the dispensed drops may contain traces of silver from the container.

Tell your doctor before you have surgery that you are using Dorzolamida/Timolol, as timolol may affect the effects of some medicines used during anesthesia.

Also, tell your doctor about any allergies or allergic reactions, including rash, swelling of the face, lips, tongue and/or throat that may cause difficulty breathing or swallowing.

Tell your doctor if you have muscle weakness or if you have been diagnosed with severe myasthenia.

If you develop any other eye irritation or new problems in the eyes, such as redness of the eyes or swelling of the eyelids, consult your doctor immediately.

If you suspect that Cosduo is causing an allergic reaction or hypersensitivity (e.g., skin rash, severe skin reaction, or redness and itching of the eyes), stop using this medicine and consult your doctor immediately.

Tell your doctor if you get an eye infection, if you suffer an eye injury, if you have eye surgery, or if you develop a reaction that includes new symptoms or worsening of existing ones.

When Cosduo is instilled in the eye, it may affect the whole body.

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

3. How to use Cosduo

Follow exactly the instructions of administration of this medicine given by your doctor. If you are not sure, consult your doctor or pharmacist again. The appropriate dose and duration of treatment will be established by your doctor.

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

If you are using Cosduo with another eye drop, the drops should be administered at least 10 minutes apart.

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

If you have difficulty administering the drops, seek help from a family member or caregiver.

Do not let the tip of the multidose container touch your eyes or the areas around them. It may cause damage to your eyes. The drops of the eye drop solution may be contaminated with bacteria that can cause eye infections that can lead to serious damage to the eyes, and even loss of vision. To avoid possible contamination of the container, avoid touching the tip of the container to any surface.

Instructions for use

Before dispensing the drops:

• Wash your hands before opening the bottle.
• Do not use this medicine if you detect that the security seal on the neck of the bottle is broken before the first opening.
• When using it for the first time, before dispensing a drop in the eye, you must practice using the dropper by slowly dispensing a drop outside the eye.
• When you are sure you can dispense one drop at a time, you should place yourself in the most comfortable position to dispense the drops (you can sit, lie down, or stand in front of a mirror).

Dispensing:

1. Hold the bottle directly under the cap and unscrew the cap to open the bottle, do not touch anything with the tip of the bottle to avoid contaminating the solution.

If you are not sure how to use this medicine, consult your doctor, pharmacist, or nurse.

1. Blink a few times to spread the drop over the eye.

1. After using Cosduo, close your eye and press the inner corner of your eye with your finger for about two minutes. This helps prevent the medicine from reaching the rest of the body.

1. Repeat instructions 2 – 5 to dispense drops in the other eye if your doctor has indicated it. In some cases, treatment is only needed in one eye, and your doctor will inform you if this applies to you and which eye needs treatment.

1. After each use and before closing it, the bottle must be shaken once downward, without touching the tip of the dropper, in order to eliminate any residual liquid in the tip. This is necessary to ensure the dispensing of the following drops.

1. At the end of the 28-day period of validity of this medicine, there will be remaining Cosduo in the bottle. Do not use the excess medicine that remains in the bottle once you have completed the treatment. Do not use the eye drops after 28 days of opening the bottle for the first time.

If you use more Cosduo than you should
