Beta-adrenergic blocker (Ophthalmic route)

Brand Names:

Dosage Forms:

Uses of This Medicine:

Beta-adrenergic blocking agents for the eye are used to treat certain types of glaucoma. They appear to work by reducing the production of fluid in the eye. This lowers the pressure in the eye.

These medicines are available only with your doctor's prescription.

Before Using This Medicine:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Infants may be especially sensitive to the effects of ophthalmic beta-adrenergic blocking agents. This may increase the chance of side effects during treatment.

Older adults

Elderly people are especially sensitive to the effects of ophthalmic beta-adrenergic blocking agents. If too much medicine is absorbed into the body, the chance of side effects during treatment may be increased.

Pregnancy

Ophthalmic beta-adrenergic blocking agents may be absorbed into the body. These medicines have not been studied in pregnant women. Studies in animals have not shown that betaxolol, levobunolol, metipranolol, or timolol causes birth defects. However, high doses of levobetaxolol given by mouth to pregnant rabbits have been shown to cause birth defects in rabbit babies, and very large doses of carteolol given by mouth to pregnant rats have been shown to cause wavy ribs in rat babies. In addition, some studies in animals have shown that beta-adrenergic blocking agents increase the chance of death in the animal fetus. Before using ophthalmic beta-adrenergic blocking agents, make sure your doctor knows if you are pregnant or if you may become pregnant.

Breast-feeding

Betaxolol and timolol, and maybe other beta-adrenergic blocking agents, when taken by mouth, may pass into the breast milk. Since ophthalmic beta-adrenergic blocking agents may be absorbed into the body, they, too, may pass into the breast milk. However, it is not known whether ophthalmic beta-adrenergic blocking agents pass into the breast milk, and these medicines have not been reported to cause problems in nursing babies.

Other medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking any of these medicines, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using medicines in this class with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Other interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other medical problems

The presence of other medical problems may affect the use of medicines in this class. Make sure you tell your doctor if you have any other medical problems, especially:

Proper Use of This Medicine:

If you have any questions about this, check with your doctor.

Storage

Keep out of the reach of children.

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Do not keep outdated medicine or medicine no longer needed.

Store levobetaxolol in an upright position.

Precautions While Using This Medicine:

Your doctor should check your eye pressure at regular visits to make certain that your glaucoma is being controlled.

Contact your physician immediately if you are having eye surgery, you experience trauma to your eye, or you develop an eye infection to determine if you should continue to use your present container of eye drops.

For a short time after you use this medicine, your vision may be blurred. Make sure your vision is clear before you drive, use machines, or do anything else that could be dangerous if you are not able to see well.

Before you have any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine. Using an ophthalmic beta-adrenergic blocking agent during this time may cause an increased risk of side effects.

For diabetic patients:

Some ophthalmic beta-adrenergic blocking agents (betaxolol, carteolol, and metipranolol) may cause your eyes to become more sensitive to light than they are normally. Wearing sunglasses and avoiding too much exposure to bright light may help lessen the discomfort.
