1. What is DORZOLAMIDA/TIMOLOL Farmalider and what is it used for

This eye drop contains two medicines: 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 lower the pressure in the eye in different ways.

Dorzolamida/Timolol Farmalider is prescribed to lower high pressure in the eye in the treatment of glaucoma, when the use of a beta-blocker eye drop alone is not adequate.

2. What you need to know before you use Dorzolamida/Timolol Farmalider

Do not use Dorzolamida/Timolol Farmalider

• if you are allergic to dorzolamida hydrochloride, timolol maleate, or any of the other ingredients of Dorzolamida/Timolol Farmalider (listed in section 6)
• if you have or have had in the past certain respiratory diseases such as asthma, or severe chronic obstructive pulmonary disease (severe lung disease which may cause wheezing, difficulty in breathing and/or coughing)
• if you have a slow heart rate, heart failure or irregular heart rhythm (irregular heartbeat)
• if you have severe kidney disease or a history of kidney stones
• if you have excess acidity of the blood caused by an accumulation of chloride in the blood (hyperchloremic acidosis)

If you are not sure whether you can use Dorzolamida/Timolol Farmalider, consult your doctor or pharmacist.

3. How to use Dorzolamida/Timolol Farmalider

Follow exactly the instructions of administration of Dorzolamida/Timolol Farmaliderindicated by your doctor. Consult your doctor or pharmacist if you have any doubts. Your doctor will determine the appropriate dose and duration of treatment.

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

If you use Dorzolamida/Timolol Farmalider with another eye drop, the application of the drops should be spaced at least 10 minutes apart.

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

Do not let the tip of the dropper touch the eye or the surrounding areas. It could become contaminated with bacteria that can cause eye infections and serious damage to the eye, including loss of vision. To avoid possible contamination of the container, wash your hands before using the medicine and keep the tip of the container away from contact with any surface. If you think that your medicine may have become contaminated, or if you have an eye infection, consult your doctor immediately to determine whether you should continue using this bottle.

Instructions for use

• First, wash your hands.
• Avoid touching the eye (or any other surface) with the tip of the dropper.
• If you wear soft contact lenses, you should remove them before using the drops and wait at least 15 minutes before putting them back.
• Dorzolamida/Timolol Farmalider comes in a plastic bottle with a cap and a dust cap with a safety seal. When using the bottle for the first time, remove the dust cap by twisting it in a clockwise direction to break the safety seal.

• Unscrew the inner cap.
• Tilt your head back and look up.
• Gently pull down the lower eyelid to form a pouch between your eyelid and your eye.

• Hold the bottle upside down over the eye and gently squeeze to release one drop. DO NOT TOUCH YOUR EYE OR EYELID WITH THE TIP OF THE BOTTLE.
• Keep your eye closed and press the inner corner of your eye with your finger for two minutes. This will help prevent Dorzolamida/Timolol Farmalider from reaching the rest of your body.
• Repeat in the other eye, if your doctor has told you to do so.
• Replace the cap on the bottle after each use, and screw the cap back on the dropper.
