Yes — Cost Plus Drugs lists Furosemide at roughly $0.017 per unit, a published price with no membership card or coupon involved. See the three-price comparison above for how that stacks up against discount-card pharmacies.

Canadian pharmacy listings in our data show Furosemide priced from about $0.120 per tablet (converted to USD), before shipping. Pack size and pharmacy both affect the final total — see the Canada pricing table for specifics.

Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.

Furosemide is the generic name for the medication sold under the brand name Lasix. Generic versions are manufactured by several companies, including Amneal Pharmaceuticals, Luitpold Pharmaceuticals, and Mylan Pharmaceuticals.

Furosemide is a loop diuretic (water pill) that helps your kidneys remove excess salt and fluid from the body. It is used to treat edema (swelling) related to heart failure, liver disease, or kidney conditions, and it may also be prescribed for hypertension. Before starting this medication, inform your doctor of your complete medical history, especially any issues with kidney function, prostate enlargement, urination problems, liver cirrhosis, electrolyte imbalances, gout, lupus, diabetes, or allergies to sulfa drugs. A full list of all medications and supplements you take is essential. Follow dosing instructions carefully to avoid serious risks like hearing loss, avoid sudden position changes to prevent dizziness, stay hydrated, and refrain from alcohol. Always take this medication under the direct supervision of your healthcare provider.

Common side effects of Furosemide can include increased urination, dizziness, nausea, diarrhea, muscle cramps, weakness, blurred vision, and ringing in the ears. It can also cause orthostatic hypotension (a drop in blood pressure upon standing) and may lower levels of potassium, magnesium, or calcium in the blood. While rare, serious allergic reactions are possible. Seek immediate medical attention for symptoms like rash, itching, swelling of the face or throat, severe dizziness, or difficulty breathing. This is not an exhaustive list, so discussing potential side effects with your doctor is crucial before beginning treatment.
