Lasix is quite a powerful water pill or diuretic taken by patients to eliminate extra salt and water from their bodies. It works by blocking the absorption of chloride, sodium and water from filtered fluid in kidneys, thus, causing an increase in urine production. In general, the onset of action of this medicine is about 1 hour after its oral administration, and its positive effect lasts around 6-8 hours. Its intake may rarely cause depletion of body water, sodium, chloride and other minerals, so this treatment should be monitored by doctors.
Doses and Common Uses
Nowadays, Lasix is often prescribed by doctors to treat edema or excessive accumulation of fluid or swelling in the body, if this condition is caused by kidney problems, heart diseases and so on. It can be taken alone or together with other pills to treat hypertension, too. Some doctors prescribe Lasix to treat hyperkalemia and hypercalcemia. It’s possible to find this medicine as special injections, oral solutions and standard tablets that come in different forms and strengths.
Most patients start taking this medication to treat edema in such doses as 20-80 mg taken as one dosage. The same dose can be repeated 6-8 hours later, but their maximum dosage can’t exceed 600 mg a day. Children should take Lasix in the doses prescribed by doctors based on their current body weight. If you need to treat high blood pressure, you should take 40 mg 2 times a day.
Unwanted Common and Rare Side Effects
Just like other pharmaceutical products available in the market, this medication may cause certain side effects, such as:
Dehydration and hypotension;
Electrolyte depletion and allergic reactions.
The good news is that most of these symptoms are mild, and they don’t bother many patients. If you notice any serious side effects, such as the following ones, you need to go to the hospital immediately:
Increased sensitivity to light and jaundice;
Ringing in your ears and skin rash;
Diarrhea and nausea;
Pancreatitis and dizziness;
Stomach pain and increased blood sugar levels.
Dangerous Drug Interactions
When undergoing this treatment, you should avoid possible drug interactions. Don’t combine the use of Lasix with such medications as aminoglycoside antibiotics, ethacrynic acid, aspirin, lithium, sucralfate and some others. All the meds that you’re taking should be discussed with your doctor because their dangerous combinations may lead to serious side effects, reduced effectiveness and other health risks.
Before you take Lasix, tell your doctor if you have any possible allergic reactions and such serious health conditions as an inability to make urine, liver and kidney problems, diabetes, lupus, gout and others. Its intake may also decrease your potassium levels in the blood and result in increased sun sensitivity. Lasix may rarely make patients feel dizzy and cause blurred vision, so they should be careful.
