Uses

Furosemide is used alone or in combination with other medications to treat high blood pressure. Furosemide is used to treat edema (fluid retention; excess fluid held in body tissues) caused by various medical problems, including heart, kidney, and liver disease. Furosemide is in a class of medications called diuretics (‘water pills’). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.

High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • if you are taking sucralfate (Carafate), take it 2 hours before or after you take furosemide.
  • tell your doctor if you have kidney disease. Your doctor may tell you not to take furosemide.
  • tell your doctor if you have or have ever had any condition that stops your bladder from emptying completely, diabetes, gout, systemic lupus erythematosus (SLE, a chronic inflammatory condition), or liver disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. Do not breast-feed while taking this medicine. If you become pregnant while taking furosemide, call your doctor.
  • if you are having surgery, tell the doctor that you are using furosemide.
  • plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Furosemide may make your skin sensitive to sunlight.
  • you should know that furosemide may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking furosemide. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up. Alcohol can add to these side effects.

Furosemide Dosage

Furosemide comes as a tablet and as a solution (liquid) to take by mouth. It usually is taken once or twice a day. When used to treat edema, furosemide may be taken daily or only on certain days of the week. When used to treat hypertension, take furosemide around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take furosemide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Furosemide controls high blood pressure and edema but does not cure these conditions. Continue to take furosemide even if you feel well. Do not stop taking furosemide without talking to your doctor.

Other

Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly, and blood tests should be done occasionally.

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking furosemide.

Do not let anyone else take your medicine. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
