Common use
Furosemide is a loop diuretic (water pill) that prevents your body from absorbing too much salt, allowing the salt to be passed in your urine instead.
Furosemide treats fluid retention in people with congestive heart failure, liver disease, or a kidney disorder such as nephrotic syndrome. This medication is also used to treat high blood pressure.
Dosage and direction
Take Furosemide exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label. Measure liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Precautions
Avoid becoming dehydrated. Follow your doctor's instructions about the type and amount of liquids you should drink while you are taking furosemide. Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Use a sunscreen (minimum SPF 15) and wear protective clothing if you must be out in the sun.
Contraindications
Before using furosemide, tell your doctor if you have:
kidney disease;
liver disease;
gout;
lupus;
diabetes; or
an allergy to sulfa drugs.
It is not known whether this medication is harmful to an unborn baby. Before taking furosemide, tell your doctor if you are pregnant or plan to become pregnant during treatment. Furosemide can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Possible side effects
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using furosemide and call your doctor at once if you have any of these serious side effects:
dry mouth, thirst, nausea, vomiting;
feeling weak, drowsy, restless, or light-headed;
fast or uneven heartbeat;
muscle pain or weakness;
urinating less than usual or not at all;
easy bruising or bleeding, unusual weakness;

headache;
numbness, burning, pain, or tingly feeling;

blurred vision.
Drug interaction
If you take sucralfate (Carafate), take it at least 2 hours before or after you take Furosemide. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
Missed dose
Furosemide is sometimes used only once, so you may not be on a dosing schedule. If you are using the medication regularly, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regular scheduled dose. Do not take extra medicine to make up the missed dose.
Overdose
Seek emergency medical attention if you think you have used too much of this medicine. Overdose symptoms may include ringing in your ears, loss of appetite, weakness, dizziness, confusion, feeling light-headed, or fainting.
Storage
Store Furosemide at room temperature away from heat, light, and moisture. Furosemide liquid medicine should be used within 60 to 90 days after opening the bottle. Ask your pharmacist how many days your medicine is good for. Throw away any unused liquid after that time has passed.
