What is Lasix?

Lasix (Furosemide) is a strong diuretic drug with a rapid effect. In medicine, according to the instructions for use, Lasix is used to relieve swelling in pathologies of the heart, kidneys or liver, when the body can no longer cope with the volume of fluid on its own.

In emergency cases, it is used to eliminate brain edema, since of all diuretics (diuretics), it acts most quickly and powerfully. Sometimes Lasix is used to treat hypertension, but usually doctors try to do with less serious drugs due to the presence of side effects.

For this reason, this medicine is prescribed only by a doctor and is available by prescription. Prolonged use of furosemide tablets for edema or high blood pressure negatively affects health and can end in death.

Release form and composition

Lasix is available in two main forms - tablets and ampoules.

In situations where emergency care is indicated, ampoules of furosemide are used in intensive care. A colorless solution is injected into the patient's vein, the effect is realized within 15 minutes after administration, reaches its peak by the end of the first hour.

Lasix tablets are white, each of them contains 40 mg of active substance. The auxiliary components in the composition of the drug are lactose monohydrate, magnesium stearate and potato starch.

How to Take Lasix

Following the instructions for use, Lasix tablets should be taken orally before meals. The frequency of use and dosage of the drug is selected by the doctor individually, focusing on the disease and its severity.

The average dosage for edema of cardiac, hepatic or renal origin is 1 tablet per day. With a severe course of the disease and pronounced symptoms, the dose increases, reaching 4 tablets per day.

With elevated blood pressure, Lasix is used in minimal dosages with mandatory monitoring of pressure indicators throughout the day.

These patients usually take special pills to reduce pressure, which simultaneously with furosemide can cause a strong drop in pressure.

Monitoring of blood pressure figures is especially important at the very beginning of therapy, when the optimal dosage of the drug to achieve the effect has not yet been selected.

Lasix for weight loss

Lasix has gained popularity among the population as a means for weight loss. A single dose of pills helps to reduce weight by 2-3 kilograms.

This result is a delight, especially for those who passionately want to lose weight: there is a feeling that taking another dose will give an even greater effect.

But this is a deception, since when taking Lasix diuretic tablets, water is lost, not adipose tissue.

All the fluid is excreted from the body, after which an unbearable feeling of thirst arises. Therefore, it is impossible to take furosemide for weight loss. A person subsequently drinks large volumes of water and the lost kilograms are returned.

Reviews and studies of the effects of Lasix suggest that in order to repeat the result, the drug should be taken regularly, while increasing the dosage, since the renal tubules gradually lose sensitivity to the drug.

Who else can't take it

Since furosemide has a pronounced diuretic effect, it has limitations and contraindications to use.

This medicine is not used for:

  • Acute renal failure – the kidneys can no longer function adequately, taking a diuretic will only worsen the situation;
  • Hypersensitivity to the active substance or auxiliary compounds – for example, Lasix tablets should not be taken with lactose intolerance;
  • Decompensated electrolyte disorders – this diuretic will enhance their manifestations;
  • Obstruction of the urinary tract - urine will be produced in large volume, but it will not be able to get out from behind the obstacle;
  • Dehydration – in this case, it is necessary to replenish the fluid, and not to remove it from the body;
  • Hepatic encephalopathy.

Furosemide is not used during pregnancy and breastfeeding (only for vital indications).

Side effects of Lasix treatment

Undesirable effects of the drug occur due to excess dosage, as well as incorrect selection of it.

Side effects on the background of taking furosemide include:

  • Vertigo;
  • Dehydration;
  • Tachycardia;
  • Lowering blood pressure;
  • Cardiac arrhythmias;
  • Muscle spasms, cramps;
  • Nausea and vomiting;
  • Visual and hearing impairments;
  • Vascular collapse;
  • Weakness, lethargy;
  • Drowsiness.

Lasix is not a potassium-sparing diuretic: when used together with urine, potassium is excreted.

It is necessary for the implementation of nervous, muscular and cardiovascular activities. When potassium deficiency occurs, the rhythm of the heart is disrupted, muscle cramps occur.

The level of potassium with prolonged use of Lasix should be monitored, since its lack can cause sudden cardiac death – cardiac arrest. It is required to take a biochemical blood test in a certain period of time set by the doctor.

The loss of calcium in the urine threatens the development of osteoporosis - bones lose their strength, become brittle and sensitive to the slightest injuries.

There is a tendency to pathological fractures: even with a small blow or fall, a person receives multiple bone injuries, which normally end in bruising of soft tissues and bruises.


Lasix also brings out magnesium: its lack is more concerned with the activity of the nervous system.

Severe neuropsychiatric disorders, depression, apathy develop. Against the background of a reduced mood, suicidal tendencies appear, which in itself is a threat to human life.

Therefore, when taking Lasix, potassium, magnesium and calcium preparations are additionally prescribed.

Current indications for the appointment of Lasix are very limited.

Doctors use it when it is necessary to achieve a quick effect when there is a serious threat to human life.

In a situation where health is not significantly threatened, it is preferable to use softer Lasix analogues. They have a gentle effect on the body, do not affect other organs and do not remove vital electrolytes from the body.

Consequences of overdose

The symptoms of an overdose of Lasix are similar to the side effects of the use, only their severity can differ.

Rhythm disturbances in case of drug overdose due to a sharp drop in potassium and the volume of fluid in the vessels can result in shock and sudden cardiac arrest.

Due to vascular collapse and pressure drop, acute renal failure develops, which is also a threat to life: toxic metabolic products accumulate in the blood, uremia and coma develop.

Due to water-electrolyte disorders, all organs suffer without exception, so the consequences of an overdose of Lasix are difficult to correct, deaths often occur.

Treatment consists in replenishing the missing fluid and electrolytes (potassium, magnesium, calcium, sodium - first of all), it is necessary to maintain the activity of vital organs.
