1. What is Diuver and what is it used for

Diuver is a diuretic. After oral administration, torasemide is rapidly and almost completely absorbed, and maximum concentration occurs in the serum after 1 to 2 hours. About 80% of the administered dose is excreted in the urine.
Indications for use:

• primary hypertension;
• edema caused by congestive heart failure, pulmonary edema, hepatic edema, and renal edema.

2. Important information before taking Diuver

When not to take Diuver

• if you are hypersensitive to torasemide, sulfonylurea derivatives (diabetes medications), or any of the other ingredients of this medicine (listed in section 6);
• if you have renal function disorders with anuria;
• if you have hepatic coma and pre-coma states;
• if you have arterial hypotension;
• if you are breastfeeding.

Warnings and precautions

Before starting Diuver, discuss it with your doctor or pharmacist:

• if you have urinary disorders, the cause of these disorders should be eliminated and water-electrolyte balance restored (especially in patients undergoing concomitant treatment with digitalis glycosides, glucocorticoids, mineralocorticoids, or laxatives);
• if torasemide therapy is long-term. During long-term treatment, regular monitoring of water-electrolyte balance, glucose, uric acid, creatinine, and lipid levels in the blood, as well as blood morphology (red and white blood cells and platelets), is recommended;
• if you have a tendency to increased uric acid levels in the blood and gout;
• if you have latent or overt diabetes. In these patients, carbohydrate metabolism should be monitored.

Due to insufficient experience with torasemide treatment, caution should be exercised in the following situations:

• pathological changes in acid-base balance,
• concomitant treatment with lithium, aminoglycosides, or cephalosporins,
• renal failure caused by nephrotoxic factors,
• children under 12 years of age.

Taking Diuver may lead to positive doping control results.
Taking Diuver as a doping agent may pose a health risk.

Children and adolescents

There is a lack of clinical experience with torasemide in this age group.

Diuver and other medicines

Tell your doctor or pharmacist about all the medicines you are taking now or have taken recently, as well as any medicines you plan to take.
In the case of concomitant use of torasemide with cardiac glycosides (medicines that stimulate heart function, increase the strength of myocardial contraction, and at the same time reduce the frequency of this contraction), there may be an increased sensitivity of the myocardium to these medicines due to decreased potassium and (or) magnesium levels in the serum.
In combination with mineralocorticoids (hormones regulating mineral and ion metabolism) and glucocorticoids (hormones regulating protein, carbohydrate, and fat metabolism) and laxatives, it may cause increased potassium excretion in the urine.
Similarly, as with other diuretics, the hypotensive effect may be enhanced when other antihypertensive medicines are administered concomitantly.
Torasemide, especially in high doses, may increase the toxicity of aminoglycoside antibiotics, cisplatin, the toxic effect of cephalosporins on the kidneys, and the toxic effect of lithium on the heart and central nervous system.
The effect of curare-like muscle relaxants and theophylline may be enhanced during concomitant use with torasemide.
Since torasemide inhibits the tubular secretion of salicylates in patients receiving high doses of salicylates, their toxicity may increase.
The effect of antidiabetic medicines may be weakened.
The use of angiotensin-converting enzyme inhibitors after torasemide treatment or the initiation of combined therapy with these medicines may cause transient blood pressure drops. This effect can be minimized by reducing the initial dose of the angiotensin-converting enzyme inhibitor and (or) reducing the dose or temporarily discontinuing torasemide for 2-3 days before using the medicine from the group of angiotensin-converting enzyme inhibitors.
Torasemide may reduce the reactivity of arteries to vasoconstrictor medicines (e.g., adrenaline, noradrenaline).
Nonsteroidal anti-inflammatory medicines (e.g., indomethacin) may reduce the diuretic and hypotensive effects of torasemide by inhibiting prostaglandin synthesis.
Probenecid may reduce the effectiveness of torasemide by inhibiting its secretion in the renal tubules.
The concomitant administration of torasemide and cholestyramine has not been studied in humans, but in animal studies, it has been found to reduce the absorption of torasemide.

Diuver with food and drink

Diuver should be taken in the morning with a small amount of liquid, regardless of meals.

Patients with liver function disorders

During torasemide treatment, patients with liver function disorders should be under special supervision due to the risk of increased torasemide levels in the blood.

Elderly patients

In elderly patients, there is no need to adjust the dosage.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
Pregnancy:
Diuver is contraindicated during pregnancy.
Breastfeeding:
There is no data on the penetration of the medicine into breast milk. Diuver is contraindicated during breastfeeding.
Fertility:
In non-clinical studies, no effect of torasemide on fertility was found.

Driving and using machines

As with other blood pressure medicines, patients taking torasemide who experience dizziness or similar symptoms should not drive or operate machines.

Diuver contains lactose monohydrate

If you have been diagnosed with an intolerance to some sugars, you should contact your doctor before taking the medicine.

Diuver contains sodium

The medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".

3. How to take Diuver

This medicine should always be taken as directed by your doctor. If you are unsure, consult your doctor or pharmacist.
Diuver is available in the following doses: 5 mg and 10 mg.
Recommended dose
Adults:

Primary hypertension

A dose of 2.5 mg orally once a day is recommended. If necessary, the dose can be increased to 5 mg once a day. Studies suggest that doses greater than 5 mg per day do not lead to further blood pressure reduction. The maximum therapeutic effect is achieved after approximately 12 weeks of treatment.

Edema

Usually, a dose of 5 mg orally once a day is used. If necessary, the dose can be gradually increased to 20 mg once a day. In individual, exceptional cases, doses of up to 40 mg per day have been used.

Taking a higher dose of Diuver than recommended

The typical picture of torasemide overdose is unknown. In the case of an overdose, significant diuresis may occur with the risk of fluid and electrolyte loss, and subsequently, drowsiness, confusion, blood pressure drop, and circulatory collapse. Gastrointestinal disorders may occur.
There is no specific antidote. The symptoms of an overdose require a reduction in dose or discontinuation of the medicine, with simultaneous administration of fluids and electrolytes.
If you have taken a higher dose of the medicine than recommended, consult your doctor or pharmacist immediately.

Missing a dose of Diuver

Take the missed dose as soon as possible. If it is almost time for the next dose, take it at the scheduled time.
Do not take a double dose to make up for the missed dose.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Common(may affect up to 1 in 10 people):
Similarly to other diuretics, depending on the dose and duration of treatment, water-electrolyte disorders may occur, especially when using a low-sodium diet. Hypokalemia (decreased potassium levels in the blood) may occur, especially in patients on a low-potassium diet, with vomiting, diarrhea, taking large amounts of laxatives, and in cases of liver function disorders.
In the case of significant diuresis, especially at the beginning of treatment, and in elderly patients, symptoms of electrolyte and fluid loss may occur, such as headache and dizziness, blood pressure drop, weakness, drowsiness, confusion, loss of appetite, and muscle cramps. It may be necessary to adjust the dose of the medicine.
Torasemide may cause increased levels of uric acid, glucose, and lipids in the serum.
Metabolic alkalosis symptoms may worsen.
Gastrointestinal disorders (e.g., loss of appetite, abdominal pain, nausea, vomiting, diarrhea, constipation) may occur.
Torasemide may cause increased activity of certain liver enzymes, e.g., gamma-GT (gamma-glutamyltransferase).
Uncommon(may affect up to 1 in 100 people):
In patients with urinary disorders, sudden urinary retention may occur.
Increased levels of urea and creatinine in the blood may occur.
Rare(may affect up to 1 in 1,000 people):
Paresthesia of the limbs.
Very rare(affects less than 1 in 10,000 people, including single cases):
