Furodemide (Lasix, Apo-furosemide)

Other Names: Lasix, Apo-furosemide

What is Furodemide Used For?

Furosemide is a diuretic or "water pill" used to treat high blood pressure. It also controls water retention caused by conditions such as heart disease. It helps your kidneys produce more urine and therefore get rid of excess salt and water in the body.

How Do You Take Furosemide?

Furosemide should be taken at the same time each day. If you take Furosemide once a day, it is best to take it in the morning. If you take it more than once a day, take the last dose no later than 4:00 p.m. unless otherwise directed by your doctor. Furosemide may be taken with or without food.

What Special Instructions Do You Need To Know?

Furosemide can decrease the amount of potassium in your blood. You may need to increase the amount of potassium-rich foods in your diet and/or take potassium supplements. However, consult with your doctor or dietician first before making any changes to your diet.

Follow a fluid restricted diet as set out by your doctor. Do not decrease your fluid intake below what the doctor has told you, as your blood pressure may become too low.

If you miss a dose, take it as soon as you remember. However, if it is too close to the time of your next dose, just take your Furosemide at the usual time. Do not double the dose.

Are There Side Effects From Taking Furosemide?

Furosemide will probably make you urinate more frequently. Other side effects you may experience include:

• dizziness, lightheadedness
• headache
• weakness

When Should You Call Your Doctor?

Call your doctor as soon as possible if you develop a rash, muscle cramps, nausea, vomiting, loss of appetite, or hearing difficulty. If your dizziness or lightheadedness does not go away or increases in severity, contact your doctor.

What Can You Do To Help?

Do not take other medications without consulting with your doctor or pharmacist first. This includes nonprescription cough, cold and allergy products, appetite suppressants and stimulants.

If you also take medications for your blood pressure such as ACE inhibitors (e.g. Ramipril, Lisinopril, Accupril, Enalapril), Digoxin, other diuretics, Lithium or NSADIDs, be sure your doctor and other health professionals (such as your dentist) are aware of this.
