Highlights for carteolol

Ophthalmic solution
1

Carteolol is an eye drop solution that’s used to reduce the pressure in your eye (intraocular hypertension) caused by conditions like glaucoma.

2

The standard dose is one drop placed into your affected eye given two times per day.

3

This drug may be absorbed into the body even though it is given as an eye drop in your eyes. This may cause problems if you have heart or lung problems or diabetes.

4

Carteolol may irritate your eyes or affect your vision. These side effects are usually temporary and get better over time. Call your doctor if these side effects last.

5

This medicine may cause low blood pressure if you’re taking a certain type of blood pressure drug (beta blocker) by mouth.

IMPORTANT INFORMATION

Heart failure

Carteolol may slow down your heart and cause severe heart failure. Your risk may be high if you already have heart problems.

People with lung problems

If you have asthma or severe chronic obstructive pulmonary disease (COPD), you shouldn’t use this drug. If you have mild to moderate COPD, you should use this drug with caution. It may make it harder for you to breathe.

People with diabetes

If you have diabetes, carteolol may mask the signs of low blood sugar.

emphysema
People with emphysema

This drug can make your shortness of breath worse.

asthma or COPD
People with asthma or COPD

You shouldn’t use this drug if you have asthma or severe chronic obstructive pulmonary disease (COPD). Use this drug with caution if you have mild or moderate COPD. If your body absorbs enough carteolol from your eyes, it may make it more difficult to breathe or prevent certain breathing medications from working as well.

heart problems
People with heart problems

You shouldn’t use this drug if you have unstable heart failure, second- or third-degree heart block, or a very slow heart rate (bradycardia) because it can make these conditions worse. If you have heart disease and you stop taking this drug suddenly, you’re at high risk for chest pain (angina) or a heart attack.

surgery
People who plan to have surgery or procedures

Tell your doctor about all the drugs that you take before you have any surgeries or medical procedures. This medication may make it harder for your heart to respond to adrenaline. This may increase your risk of complications with anesthesia and surgical procedures. You shouldn’t stop taking the drug before your surgery unless your doctor directs you to.

People with diabetes

If your body absorbs enough carteolol from your eyes, it can mask some of the signs of low blood sugar, especially fast heart rate. If you’re on insulin or other diabetes drugs, you may need to test your blood sugar more often.

thyroid problems
People with thyroid problems

If your body absorbs enough carteolol from your eyes, it may mask the signs and symptoms of hyperthyroidism, such as a fast heart rate. If you stop taking this drug suddenly, it may make your hyperthyroidism symptoms worse and you may need medical help right away. Tell your doctor if you have thyroid problems before you start taking this drug.

pregnant women
Pregnant women

Carteolol is a pregnancy category C drug. That means two things:

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.

Tell your doctor if you’re pregnant or plan to become pregnant. Carteolol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

breast-feeding
Women who are breast-feeding

It isn’t known if carteolol passes into breast milk. If it does, there may be serious side effects in a child who is breastfed.

You and your doctor may need to decide if you’ll take carteolol or breastfeed.

Pharmacist's Advice
Clinical Associate Professor, University of Illinois at Chicago College of Pharmacy

Carteolol comes with serious risks if you don't take it as prescribed.

If you don't take it at all

The eye condition that you’re treating may become worse. It may cause permanent damage, including poorer vision and blindness.

If you stop taking it suddenly

You may have some of the symptoms of your eye condition, such as trouble with side vision (peripheral vision) or blurred vision.

If you don't take it on schedule

You may have symptoms of your eye condition.

What to do if you miss a dose

If you forget to take your dose, take it as soon as you remember. If it’s just a few hours until the time for your next dose, then wait and only take one dose at that time. Never try to catch up by giving yourself more drops at one time than you’re prescribed. This could cause toxic side effects.

If you take too much

You may experience some of the side effects of carteolol, such as:

  • slowed heart rate (bradycardia)
  • low blood pressure (hypotension)
  • lightheadedness
  • dizziness
  • fainting
  • trouble breathing
  • swelling in your chest, legs, or ankles

If you think you’ve taken too much of the drug, act right away. Call your doctor or local Poison Control Center, or go to the nearest emergency room.

How to tell this drug is working

Glaucoma or high blood pressure in the eye usually doesn’t cause symptoms. So, you may not be able to tell if this drug is working. Your doctor may monitor the pressure in your eyes to see if carteolol is working for you.

Carteolol is a long-term drug treatment.

There is no cure for glaucoma. If your vision has gotten worse, there’s no way to make it better. However, treatment with carteolol can help save your remaining vision and prevent further loss of vision.

Carteolol must be stored at the right temperature

  • Store carteolol at room temperature between 59°F (15°C) and 77°F (25°C).
  • Keep it away from light.

Travel

When traveling with your medication:

  • Always carry it with you, such as in your carry-on bag.
  • Don’t worry about airport x-ray machines. They can’t hurt this medication.
  • You may need to show airport staff your pharmacy’s label to clearly identify the medication. Keep the original prescription label with you when traveling.
  • Don’t leave this medicine in the car, especially when the temperature is hot or freezing.

Self-management

When you administer carteolol drops, follow these steps:

  • Wash your hands.
  • Hold the bottle upside down.
  • Tilt your head back.
  • Hold the bottle in one hand and place it as close to your eye as you can.
  • With the other hand, pull down your lower eyelid to form a pocket.
  • Place the prescribed number of drops into the lower eyelid pocket. If you’re using more than one eye drop, wait at least 5 minutes before applying the second one.
  • Either close your eye or press the lower lid lightly with your finger for at least one minute to keep the drops in the eye.

Clinical monitoring

While you’re taking carteolol, your doctor may do tests to measure the pressure in your eye. This test is called intraocular pressure (IOP). It’s done at your eye doctor and feels like a puff of air into your eye.

Not every pharmacy stocks this drug

When filling your prescription, be sure to call ahead.

Insurance

Many insurance companies require a prior authorization for this drug. This means your doctor will need to get approval from your insurance company before your insurance company will pay for the prescription.

Are there any alternatives?

There are other drugs available to treat your condition. Some may be more suitable for you than others. Talk to your doctor about possible alternatives.
