Contents of the package and additional information

COSOPT contains two medications: dorzolamide and timolol.

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

These medications lower eye pressure in different ways.

COSOPT is prescribed to reduce elevated intraocular pressure in the treatment of glaucoma when the use of a beta-blocker eye drop as monotherapy is not suitable.

No use COSOPT

• If you are allergic to dorzolamide hydrochloride, timolol maleate, or any of the other components of this medication (listed in section6).
• If you have or have had respiratory problems, such as asthma or severe chronic obstructive pulmonary disease (a serious lung disease that can cause wheezing, difficulty breathing, and/or long-standing cough).
• If you have a slow heart rate, heart failure, or irregular heart rhythm.
• If you have severe kidney disease or a history of kidney stones.
• If you have excessive blood acidity caused by a buildup of chloride in the blood (hyperchloremic acidosis).

If you are unsure whether you should use this medication, consult your doctor or pharmacist.

Warnings and Precautions

Consult your doctor before starting to use COSOPT.

Inform your doctor of any current or past medical or ocular problems:

• Coronary heart disease (symptoms may include chest pain or tightness, difficulty breathing, or choking), heart failure, low blood pressure.
• Irregular heart rhythm, such as decreased heart rate.
• Respiratory problems, asthma, or chronic obstructive pulmonary disease.
• Poor blood circulation (such as Raynaud's disease or Raynaud's syndrome).
• Diabetes, as timolol may mask signs and symptoms of low blood sugar.
• Hyperthyroidism, as timolol may mask signs and symptoms.

Inform your doctor before undergoing surgery that you are using COSOPT, as timolol may affect the effects of some medications used during anesthesia.

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

Inform your doctor if you experience muscle weakness or have been diagnosed with myasthenia gravis (muscle weakness).

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

If you suspect that COSOPT is causing an allergic reaction or hypersensitivity (such as skin rash, severe skin reaction, or eye redness and itching), stop using this medication and consult your doctor immediately.

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

COSOPT may affect the entire body when instilled in the eye.

There is limited clinical data on the administration in infants and children.

Older patients

In studies with COSOPT, the effects of this medication were similar in older patients and younger patients.

Use in patients with liver impairment

Use of COSOPT with other medications

COSOPT may affect or be affected by other medications you are using, including other eye drops for glaucoma treatment. Inform your doctor if you are using or plan to use medications to lower blood pressure, heart medications, or diabetes medications. Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication. This is particularly important if you are:

• Using medications to lower blood pressure or treat heart disease (such as calcium channel blockers, beta blockers, or digoxin).
• Using medications to treat irregular heart rhythm, such as calcium channel blockers, beta blockers, or digoxin.
• Using another eye drop that contains beta blockers.
• Using another carbonic anhydrase inhibitor, such as acetazolamide.
• Using monoamine oxidase inhibitors (MAOIs).
• Using a cholinergic agonist that may have been prescribed to help eliminate urine. Cholinergic agonists are also a type of medication that may be used to help restore normal movements through the intestines.
• Using narcotics, such as morphine used to treat moderate to severe pain.
• Using medications to treat diabetes.
• Using antidepressants known as fluoxetine and paroxetine.
• Using a sulfonamide.
• Using quinidine (used to treat heart disorders and some types of malaria).

Do not change the medication dose without consulting your doctor.

The incidence of side effects after topical ocular administration is lower than when medications, for example, are taken by mouth or injected. Additional listed side effects include reactions that appear within the class of beta-blockers when used to treat eye disorders.

Low blood sugar levels, congestive heart failure, a type of heart rhythm alteration, abdominal pain, vomiting, muscle pain not caused by exercise, sexual dysfunction, hallucinations, sensation of a foreign body in the eye (sensation of having something in the eye), increased heart rate, and increased blood pressure.
