What is torsemide, and how does it work?
Torsemide (Demadex) is a potent drug that's a diuretic (water pill). This medicine causes a profound increase in urine output (diuresis) by preventing the kidney from retaining water. Specifically, it blocks the reabsorption back into the blood of sodium and water that has been filtered out of the blood in the kidneys.
It is in a class of diuretic drugs called "loop" diuretics, which also includes the drugs furosemide (Lasix) and bumetanide (Bumex). Torsemide 10-20 mg is approximately equivalent to 1 mg of bumetanide and 40 mg of furosemide. The potent diuretic effect of torsemide can cause the loss of large amounts of body water leading to dehydration as well as the loss of electrolytes (for example, sodium, potassium, magnesium, and calcium). Therefore, careful medical supervision is necessary during treatment.
What brand names are available for torsemide?
Demadex is the brand name for this medication in the US.

Do I need a prescription for it?
Yes, your medical doctor or health care professional will need to write you a prescription for the medication.
What are the uses for torsemide?
This drug is prescribed by doctors to treat several diseases and conditions.
- Torsemide (Demadex) is used for the medical treatment of edema (water retention) due to congestive heart failure, kidney disease, chronic kidney failure, or liver disease.
- It also is used alone or combined with other antihypertensive medications for the treatment of high blood pressure (hypertension).
Who shouldn't take Demadex?
- Patient's shouldn't take Demadex if they are allergic to it or to sulfonylureas to which it is related.
- Don't take it if you aren't able to urinate.
- Patients with liver disease with cirrhosis and ascites should use this drug with caution because sudden changes in fluid and electrolyte balance can cause hepatic coma.
Torsemide side effects
- Dry mouth
- Reduced kidney function
- Heart arrhythmias
- Muscle aches and pains
Possible side effects of this medication reported often include:
- Excessive urination
- Runny nose
- ECG abnormality
- Joint pain
- Stomach upset
- Sore throat
- Muscle pain
Possible serious side effects adverse effects include:
- Atrial fibrillation
- Chest pain
- Gastrointestinal bleeding
- High blood sugar (hyperglycemia)
- Increased uric acid (hyperuricemia)
- Low blood potassium (hypokalemia)
- Low blood pressure (hypotension)
- Dehydration (symptoms listed previously)
- Shunt thrombosis
- Rectal bleeding
- Ventricular tachycardia
- Serious skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis)
- Allergic reactions
- Reduced number of white blood cells and platelets
Demadex can cause dehydration and loss of potassium and other electrolytes. Low potassium levels (hypokalemia) can cause abnormal heart beats especially in people with heart disease or those taking the medicine digoxin (Lanoxin). Levels of potassium and other electrolytes should be monitored during medical treatment with this medicine.
What dosages are available for torsemide, and how do I take it?
- Torsimide (Demadex) comes in tablets of 5, 10, 20, and 100 mg. The 10 mg/ml injectable solution has been discontinued.
- Patients can take the tablets at any time without regard to meals. (You can take it on an empty stomach.)
- For the treatment for patients with heart failure the initial dose is 10 to 20 mg by mouth or injection once daily. The dose may be doubled until the desired diuretic effect is achieved. The maximum dose is 200 mg daily.
- Chronic kidney failure is treated with 20 to 200 mg orally or by injection once daily.
- The dose for treating high blood pressure is 2.5 to 10 mg orally once daily.
- Liver cirrhosis is treated with 5 to 40 mg orally or by injection once daily. It is combined with aldosterone antagonists or potassium-sparing diuretics.
Which drugs or supplements might cause interactions?
Several medicines may cause interactions with torsemide.
- Torsemide can cause low blood potassium, calcium, and magnesium levels. These changes can increase the risk of toxicity from digoxin (Lanoxin). Combining torsemide with other diuretics such as metolazone (Zaroxolyn), hydrochlorothiazide, or chlorthalidone (Hygroton) can exaggerate the losses of potassium and magnesium.
- The body's ability to eliminate lithium (Lithobid, Eskalith) may decrease in patients receiving torsemide. Therefore, careful monitoring of lithium levels in blood is recommended when torsemide and lithium are taken together in order to prevent increases in lithium levels and lithium toxicity.
- Indomethacin (Indocin) can reduce the diuretic and blood pressure-lowering effects of other loop diuretics (for example furosemide) and it probably can do the same with torsemide. Other nonsteroidal anti-inflammatory drugs, for example, ibuprofen (Motrin), naproxen (Naprosyn) may interact similarly.
- Concomitant use of torsemide and aminoglycosides may increase the risk of hearing impairment since both agents can affect hearing.
- Probenecid decreases the diuretic effect of torsemide by reducing secretion of torsemide into the kidney tubules.
Is torsemide safe to use during pregnancy or while breastfeeding?
- Researches, doctors, and other health care professionals haven't established the safety of Demadex in pregnant women.
- It's also not known whether it's excreted in human milk.
Storage and FDA approval
- Keep this drug stored at room temperature, 15 C to 30 C (59 F to 86 F).
- The FDA approved torsemide in August, 1993.

CirrhosisCirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections.
Symptoms include yellowing of the skin (jaundice), itching, and fatigue.
The prognosis is good for some people with cirrhosis of the liver, and the survival can be up to 12 years; however the life expectancy is about 6 months to 2 years for people with severe cirrhosis with major complications.
Congestive Heart Failure (CHF) OverviewCongestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
Fatty LiverNonalcoholic fatty liver disease occurs due to the accumulation of abnormal amounts of fat within the liver. Fatty liver most likely caused by obesity and diabetes. Symptoms of fatty liver disease are primarily the complications of cirrhosis of the liver; and may include:
- mental changes,
- liver cancer,
- the accumulation of fluid in the body (ascites, edema), and
- gastrointestinal bleeding.
- weight loss, and
- bariatric surgery.
Heart AttackHeart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.

High Blood Pressure Hypertension
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis.
Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.
Liver (Anatomy and Function)The liver is the largest gland and organ in the body. There are a variety of liver diseases caused by liver inflammation, scarring of the liver, infection of the liver, gallstones, cancer, toxins, genetic diseases, and blood flow problems. Symptoms of liver disease generally do not occur until the liver disease is advanced. Some symptoms of liver disease include jaundice, nausea and vomiting, easy bruising, bleeding excessively, fatigue, weakness, weight loss, shortness of breath, leg swelling, impotence, and confusion. Treatment of diseases of the liver depend upon the cause.

Lungs Design And PurposeThe lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
ParathyroidectomyParathyroidectomy is the removal of one or more of the parathyroid glands to treat hyperparathyroidism. Risks of parathyroidectomy include:
- paralysis of the vocal cords,
- difficulty swallowing thin liquids,
- difficulty breathing,
- and drug reactions.
- damage to the recurrent laryngeal nerve,
- bleeding or hematoma,
- problems maintaining calcium levels in the blood,
- need for further and more aggressive surgery,
- need for a limited or total thyroidectomy,
- prolonged pain,
- impaired healing,
- and recurrence of the tumor.
Stroke Symptoms and TreatmentA stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic).
Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke.
Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
