1. WHAT COSOPT IS AND WHAT IT IS USED FOR
Cosopt 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 the pressure in the eye in different ways.
Cosopt is prescribed to lower raised pressure in the eye in the treatment of glaucoma when beta-blocker eyedrop medicine used alone is not adequate.
2. BEFORE YOU USE COSOPT
Do not use COSOPT
• if you are allergic (hypersensitive) to dorzolamide hydrochloride, timolol maleate or any of the other ingredients of Cosopt.
• 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 heart beat, heart failure or disorders of heart rhythm (irregular heart beats).
• if you have severe kidney problems, or a prior history of kidney stones.
• if you have excess acidity of the blood caused by a build up of chloride in the blood (hyperchloraemic acidosis).
If you are not sure whether you should use this medicine, contact your doctor or pharmacist.
Take special care with Cosopt
Tell your doctor about any medical or eye problems you have now or have had in the past:
• 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.
Tell your doctor before you have an operation that you are using Cosopt as timolol may change effects of some medicines used during anaesthesia.
Also tell your doctor about any allergies or allergic 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 Cosopt 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 Cosopt is instilled into the eye it may affect the entire body.
If you wear soft contact lenses, you should consult your doctor before using this medicine.
Use in children
There is limited experience with Cosopt in infants and children.
Use in elderly
In studies with Cosopt, the effects of this medicine were similar in both elderly and younger patients.
Use in patients with liver impairment
Tell your doctor about any liver problems you now have or have suffered from in the past.
Using other medicines
Cosopt 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. Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. 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 eyedrop that contains a beta-blocker.
• taking another carbonic anhydrase inhibitor such as acetazolamide.
• taking monoamine oxidase inhibitors (MAOIs) which are used to treat depression.
• 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
Ask your doctor or pharmacist for advice before taking any medicine.
Use in pregnancy
Do not use Cosopt if you are pregnant unless your doctor considers it necessary.
Use in breast-feeding
Do not use Cosopt if you are breast-feeding. Timolol may get into your milk. Ask your doctor for advice before taking any medicine during breast-feeding.
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 Cosopt, 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.
Important information about some of the ingredients of Cosopt
If you wear soft contact lenses, you should consult your doctor before using Cosopt (the preservative benzalkonium chloride may possibly discolour the lenses).
3. HOW TO USE COSOPT
Always use Cosopt exactly as your doctor has told you. You should 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 usual dose is one drop in the affected eye(s) in the morning and in the evening.
If you are using this medicine 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.
Do not allow the tip of the container to touch the eye or areas around the eye. It 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 container, wash your hands before using this medicine and keep the tip of the container away from contact with any surface. If you think your medication may be contaminated, or if you develop an eye infection, contact your doctor immediately concerning continued use of this bottle.
Instructions for use
1. Before using the medication for the first time, be sure the Safety Strip on the front of the bottle is unbroken. A gap between the bottle and the cap is normal for an unopened bottle.
Opening Arrows^ Safety strips
2. Tear off the Safety Strip to break the seal.
Gap^
Finger Push Area^
3. To open the bottle, unscrew the cap by turning as indicated by the arrows on the top of the cap. Do not pull the cap directly up and away from the bottle. Pulling the cap directly up will prevent your dispenser from operating properly.
Finger Push Area
4. Tilt your head back and pull your lower eyelid down eye.
5. Invert the bottle, and press lightly with the thumb or index finger over the “Finger Push Area” (as shown) until a single drop is dispensed into the eye as directed by your doctor.
POM
DO NOT TOUCH YOUR EYE OR EYELID WITH THE DROPPER TIP.
6. After using Cosopt press a finger into the corner of your eye, by the nose, or close your eyelids for 2 minutes. This helps to stop the medicine from getting into the rest of the body.
7. Close your eye for a moment and press the inner corner of the eye with your finger for about one minute. This helps to prevent the eye drop from draining down the tear duct.
8. If drop dispensing is difficult after opening for the first time, replace the cap on the bottle and tighten (Do not overtighten) and then remove by turning the cap in the opposite directions as indicated by the arrows on the top of the cap.
9. Repeat steps 4 & 5 with the other eye if instructed to do so by your doctor.
10. Replace the cap by turning until it is firmly touching the bottle. The arrow on the left side of the cap must be aligned with the arrow on the left side of the bottle label for proper closure. Do not overtighten or you may damage the bottle and cap.
11.The dispenser tip is designed to provide a single drop; therefore, do NOT enlarge the hole of the dispenser tip.
12.After you have used all doses, there will be some Cosopt left in the bottle. You should not be concerned since an extra amount of this medicine has been added and you will get the full amount of Cosopt that your doctor prescribed. Do not attempt to remove the excess medicine from the bottle.
If you use more Cosopt 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 Cosopt
It is important to use this medicine 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 use a double dose to make up for the forgotten dose.
If you stop using Cosopt
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.
