Chemical Name: FUROSEMIDE (fur-OH-se-mide)
Furosemide is a loop diuretic used to treat high blood pressure, congestive heart failure, and swelling due to excess body water. Furosemide may also be used to treat other conditions as determined by your doctor.
WARNING: Furosemide is a strong "water pill" (diuretic). Using too much of Furosemide can lead to serious water and mineral loss. Therefore, it is important you be monitored by your doctor. Promptly notify your doctor if you become very thirsty, have a dry mouth, become confused, or develop muscle cramps/weakness. Some medicines or medical conditions may interact with Furosemide. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. ADDITIONAL MONITORING OF YOUR DOSE OR CONDITION may be needed if you are taking anticoagulants, parenteral aminoglycosides, chloral hydrate, cisplatin, digitoxin, digoxin, ginseng, or indomethacin. Inform your doctor of any other medical conditions, allergies, pregnancy, or breast-feeding. Contact your doctor or pharmacist if you have any questions or concerns about taking Furosemide.
Follow the directions for using Furosemide provided by your doctor. Furosemide may be taken on an empty stomach or with food. WHEN YOU FIRST START TAKING Furosemide, it may cause an increase in urine or in frequency of urination. If you are taking 1 dose daily, take it in the morning to prevent Furosemide from affecting your sleep. If you are taking more than 1 dose, take the last dose no later than 6 pm. STORE Furosemide at room temperature in a tightly-closed container, away from heat and light. IF YOU MISS A DOSE OF Furosemide, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
DO NOT TAKE Furosemide if you have had an allergic reaction to it or are allergic to any ingredient in Furosemide. Laboratory and/or medical tests, including blood electrolytes, kidney function, and blood glucose may be performed to monitor your progress or to check for side effects. KEEP ALL DOCTOR AND LABORATORY APPOINTMENTS while you are taking Furosemide. YOUR DOCTOR MAY HAVE ALSO PRESCRIBED a potassium supplement for you. If so, follow the dosing carefully. Do not start taking additional potassium on your own or change your diet to include more potassium without first checking with your doctor. DO NOT DRIVE, OPERATE MACHINERY, OR DO ANYTHING ELSE THAT COULD BE DANGEROUS until you know how you react to this medicine. Using Furosemide alone, with other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks. Furosemide MAY CAUSE DIZZINESS, lightheadedness, or fainting. Alcohol, hot weather, exercise, and fever can increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Also, sit or lie down at the first sign of dizziness, lightheadedness, or weakness. Furosemide MAY CAUSE increased sensitivity to the sun. Avoid exposure to the sun, sunlamps, or tanning booths until you know how you react to Furosemide. Use a sunscreen or protective clothing if you must be outside for a prolonged period. BEFORE YOU BEGIN TAKING ANY NEW MEDICINE, either prescription or over-the-counter, check with your doctor or pharmacist.
