Consumer Medicine Information This leaflet answers some common questions about Lasix oral medicines (tablets, oral solution) and injections. It does not take the place of talking to your doctor or pharmacist. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you. Lasix contains furosemide (frusemide), which belongs to a family of drugs called diuretics. If you have any concerns about taking this medicine, ask your doctor or pharmacist. A diuretic helps reduce the amount of excess fluid in the body by increasing the amount of urine produced. Lasix is used to treat swelling of the ankles, feet, legs or even the brain or lungs. This swelling is called oedema and can occur in some heart, lung, liver or kidney conditions. Lasix may be used in some patients with more serious kidney problems who may have some fluid retention. Lasix may also be used to lower high blood pressure (which is also called hypertension). This pressure helps move your blood around your body. Your blood pressure may vary at different times of the day, depending on how busy or worried you are. Using too much of this drug can lead to serious water and salt/mineral loss. Therefore, it is important that you are closely monitored by your doctor while taking this medication. Show More Furosemide is used to reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, and kidney disease. Tell your doctor right away if you become very thirsty or confused, or develop muscle cramps/weakness. This can lessen symptoms such as shortness of breath and swelling in your arms, legs, and abdomen. This drug is also used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Furosemide is a "water pill" (diuretic) that causes you to make more urine. This helps your body get rid of extra water and salt.
Tell your doctor if you are on a salt restricted diet. If you have not told your doctor about any of the above, tell them before you take Lasix. Taking other medicines.
