Is the Lasix on SGMeds a generic?
Yes. SGMeds ships a generic with the same active ingredient (furosemide) at the strength you choose, not the original Lasix made by Sanofi. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
How is Lasix priced?
Lasix comes in 40 and 100mg strengths, in packs of 20 to 360 tablets. Each option's price is shown on this page in Singapore dollars, converted from US dollars, so the exchange rate can change the final amount. Larger packs work out cheaper per tablet.
