Lasix excretes an excessive liquid from the body and reduces edemas. This is a loop diuretic that has Furosemide.
A distinctive feature of Lasix is a very fast and intensive diuretic effect. Sodium is discharged within 15-20 minutes after the oral use of a onetime therapeutic dose, and so an excretion of water/liquid happens.
In 30 minutes after the use of Lasix, a human has frequent desires to urinate and a process of the liquid excretion begins. The effect lasts for a short period, within 3-4 hours. But it is possible to significantly reduce edema and even lower the blood pressure.
An excretion of the excessive liquid lowers the blood pressure. Water does not press on the blood vessels, they are dilated and a normal blood circulation is restored. As the effect of Lasix occurs quickly, the drug is used to lower pressure during hypertonic crisis.
Furosemide is characterized by “a rebound syndrome”. An excretion of sodium is increased by 2-3 times during the action of a tablet, but the level of sodium turns out to be low after the end of the Lasix action. Therefore, in case of the edema syndrome, the application of Lasix may cause a pendulum effect. Edemas will be reduced after the use of a tablet, and liquid may be accumulated again within 3-4 hours after the use of a tablet but in less amount.
In what dose is Lasix used?
In case of the edema syndrome, a standard dose of Lasix 40 mg is used. If a natural excretion of the liquid from the body did not increase within 2 hours after the use, Lasix is used in the dose of 20 mg every 4 hours. As soon as an intensive diuresis has started, a dose is decreased.
To treat arterial hypertension, a standard therapeutic dose of Lasix is 20-40 mg per day. If it is not enough, a dose is not increased. To increase a hypotensive effect, other products lowering the blood pressure are added to the therapy.
- Take due care while taking Lasix for along time. A lot of good minerals including calcium and potassium are excreted with the liquid. Therefore it is necessary to regularly control the level of electrolytes in the blood plasma and take additional vitamins and minerals
- Adding Lasix to the hypotensive medical products, their dose should be reduced by 2 times
- Do not take Lasix during acute renal/hepatic failure, obstruction of the urinary tracts, severe cardiovascular diseases, and gout
- The use of Lasix is not recommended in the first half of pregnancy term. The Lasix tablets may be used in the second half of the pregnancy term but only in the minimal dose of 20 mg and in case of urgent need
Tachycardia, hypotension, muscle spasms, headache, dry mouth, skin itching are the side effects that may be cause by the use of Lasix.
High doses of Lasix may cause severe side effects including severe allergic reactions and coma. Therefore, a general health condition should be controlled during the treatment. If the side effects appeared, visit a physician.
