(pronounced “CO-sopt”)

Read this information before you start using COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) and each time you refill your prescription. This is in case any information has changed. This leaflet provides a summary of certain information about COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) . Your doctor or pharmacist can give you more complete information about COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) . This leaflet does not take the place of careful discussions with your doctor. You and your doctor should discuss COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) when you start using your medicine and at regular checkups. Only your doctor can prescribe COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) for you.

What is COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) ?

COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) is an eyedrop. It contains dorzolamide hydrochloride, which is an ophthalmic carbonic anhydrase inhibiting drug. It also contains timolol maleate, which is a beta-blocking drug. Both drugs work to lower pressure in the eye, but in different ways.

COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) is a medicine for lowering pressure in the eye in people with open-angle glaucoma or ocular hypertension. It is used when a beta-blocker eyedrop alone is not adequate to control eye pressure.

What should I know about high pressure in the eye?

People with open-angle glaucoma or ocular hypertension have pressures in one or both of their eye(s) that are too high for them.

High pressure in the eye may damage the optic nerve. This may lead to loss of vision and possible blindness. There generally are few symptoms that you can feel to tell you whether you have high pressure within your eye. Your doctor needs to examine your eyes to determine this. If you have high pressure in your eye, you will need your pressure checked and your eyes examined regularly.

Who should not use COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) ?

Do not use COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) if you have:

  • asthma or have ever had asthma,
  • severe lung problems,
  • slow or irregular heartbeat or heart failure,
  • allergies to any of its ingredients. See the list at the end of the leaflet.

If you are not sure whether you should use COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) , contact your doctor or pharmacist.

What should I tell my doctor before and during treatment with COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) ?

Tell your doctor:

  • if you are pregnant or plan to become pregnant,
  • if you are breast-feeding or intend to breast-feed,
  • about any medical problems you have now or had in the past, especially heart problems or breathing problems including asthma,
  • if you now have or had in the past kidney or liver problems,
  • if you have diabetes, thyroid disease or muscle weakness,
  • about all medicines that you are taking or plan to take, including those you can get without a prescription,
  • about any allergies including allergies to any medications, especially sulfa drugs,
  • if you develop an eye infection, develop a red or swollen eye or eyelid, receive an eye injury, have eye surgery, or develop new or worsening eye symptoms,
  • if you plan on having any type of surgery.

How should I use COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) ?

COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) is an eyedrop. The usual dose is one drop in the morning and one drop in the evening. Your doctor will tell you if just one or both eyes are to be treated.

If you are using COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) with another eyedrop, the eyedrops should be used at least 10 minutes apart. It is very important to use your medication exactly as directed by your doctor. If you stop using your medicine, contact your doctor immediately.

COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) contains a preservative called benzalkonium chloride. This preservative may be absorbed by soft contact lenses. Contact lenses should be removed before using COSOPT (dorzolamide hydrochloride-timolol maleate ophthalmic solution) . The lenses can be placed back into your eyes 15 minutes after using the eyedrops.

Do not allow the tip of the bottle to touch the eye or areas around the eye. The bottle may become contaminated with bacteria. This can cause eye infections leading to serious damage to the eye, even loss of vision. Keep the tip of the bottle away from contact with any surface to avoid contamination.
