Lasix is a loop diuretic (water pill) that prevents your body from absorbing too much salt, allowing the salt to instead be passed in your urine. Lasix treats fluid retention (edema) 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 (hypertension). Lasix may also be used for other purposes not listed in this medication guide.

Take this medication 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. Your doctor may occasionally change your dose to make sure you get the best results from Lasix. Lasix will make you urinate more often and you may get dehydrated easily. Follow your doctor's instructions about using potassium supplements or getting enough salt and potassium in your diet. To be sure Lasix is not causing harmful effects, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled appointments. If you are being treated for high blood pressure, keep using Lasix even if you feel fine. High blood pressure often has no symptoms.

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 Lasix 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
  • a red, blistering, peeling skin rash
  • hearing loss; or
  • nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).


Less serious side effects may include:

  • diarrhea, constipation, or stomach pain
  • headache
  • numbness, burning, pain, or tingly feeling
  • dizziness; or
  • blurred vision.


This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect.

If you take sucralfate (Carafate), take it at least 2 hours before or after you take Lasix.

Before taking Lasix, tell your doctor if you are using any of the following drugs:

lithium
digoxin (Lanoxin)
steroids (prednisone and others)
ethacrynic acid (Edecrin)
diet pills or cold medicine
other blood pressure medications;
amikacin (Amikin), gentamicin (Garamycin), netilmicin (Netromycin), streptomycin, tobramycin (Nebcin, Tobi)
salicylates such as aspirin, Disalcid, Doan's Pills, Dolobid, Salflex, Tricosal, and others; or
indomethacin.

This list is not complete and there may be other drugs that can interact with Lasix. 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.

Lasix may increase the ototoxic potential of aminoglycoside antibiotics, especially in the presence of impaired renal function. Except in life-threatening situations, avoid this combination.

Lasix should not be used concomitantly with ethacrynic acid because of the possibility of ototoxicity. Patients receiving high doses of salicylates concomitantly with LASIX, as in rheumatic disease, may experience salicylate toxicity at lower doses because of competitive renal excretory sites.

Lasix has a tendency to antagonize the skeletal muscle relaxing effect of tubocurarine and may potentiate the action of succinylcholine.

Lithium generally should not be given with diuretics because they reduce lithium's renal clearance and add a high risk of lithium toxicity.

Lasix may add to or potentiate the therapeutic effect of other antihypertensive drugs.

Potentiation occurs with ganglionic or peripheral adrenergic blocking drugs.

Lasix may decrease arterial responsiveness to norepinephrine. However, norepinephrine may still be used effectively.

Simultaneous administration of sucralfate and LASIX tablets may reduce the natriuretic and antihypertensive effects of LASIX. Patients receiving both drugs should be observed closely to determine if the desired diuretic and/or antihypertensive effect of LASIX is achieved. The intake of LASIX and sucralfate should be separated by at least two hours.

Lasix 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 regularly scheduled dose. Do not take extra medicine to make up the missed dose.
Store Lasix at room temperature away from heat, light, and moisture.
