Common Questions about furosemide (Lasix)

Should I drink more water while taking furosemide?

Yes, it is important to stay well-hydrated while on furosemide, especially during hot weather, and exercise when you sweat a lot. Sweating excessively while on furosemide can lead to low blood pressure, dehydration, and electrolyte imbalances. However, if you are taking furosemide to reduce edema, be careful not to drink too much water. Ask your doctor how much water you should drink every day. 

Can furosemide damage the kidneys?

Diuretics can cause acute urinary retention (too little urine formation) and other kidney problems. Make sure you keep all your appointments with your healthcare provider because they may want to order medical tests to check kidney function while you are on this medication. Call your doctor if you notice any problems with urination while on furosemide.

How long does it take for furosemide to start working?

Furosemide is a fast-acting and powerful diuretic that starts working within 1 hour. The effects of the medicine last for 6-8 hours. You should not take a dose of furosemide sooner than 6-8 hours after a previous dose, as this can increase the risk of severe fluid and electrolyte abnormalities. 

What is the best time of day to take furosemide?

Doctors generally advise taking furosemide earlier in the day to avoid nighttime urination, for example, at 8 am and 2 pm. Talk to your doctor about the appropriate time to take your dose(s).

Will Lasix help swollen feet?

Yes, Lasix (furosemide) can help reduce swelling in all parts of the body, including the feet and legs. However, you should not take this medication unless advised by a doctor, as it can cause serious adverse effects.
