Who is this for?

For adults (18+). Standard adult dosing applies: see the How to Take tab for full instructions.

What is this drug?

Torsemide is a strong water pill (diuretic) that helps your body get rid of excess water and salt by making you urinate more, which helps reduce swelling and lower blood pressure.

How it works

Inhibits the Na-K-2Cl cotransporter (NKCC2) in the thick ascending limb of the loop of Henle, blocking sodium and chloride reabsorption and increasing urinary water excretion. This reduces circulating fluid volume, thereby lowering blood pressure and alleviating oedema and pulmonary congestion associated with heart failure and renal or hepatic disease.

What to watch out for

Only buy from reputable pharmacies and avoid roadside sellers or unregistered vendors, as fake drugs are common. Drink enough water to stay hydrated but follow your doctor's advice on fluid intake. Because this drug makes you urinate a lot, take it in the morning and not at bedtime so your sleep is not disturbed.

Common Side Effects

Frequent urination (especially in the first few days)
dizziness or lightheadedness
headache
mild stomach upset
feeling weak or tired

Serious Side Effects

Severe dehydration signs like very dry mouth
extreme thirst
confusion
or fainting require you to go to the hospital immediately. Hearing problems such as ringing in the ears or sudden hearing loss require urgent medical attention. Irregular heartbeat or muscle cramps could mean your body salts (electrolytes) are dangerously low
so see a doctor right away.

Drug Interactions

Avoid taking torsemide with other blood pressure drugs without your doctor adjusting the doses, as your blood pressure could drop too low. Be careful if you are taking drugs like digoxin for heart problems, because torsemide can lower your potassium levels and make digoxin more dangerous. Alcohol can worsen dizziness and dehydration, so avoid or limit alcohol while using this drug.
