I have chf. should i take lasix (furosemide) if i don't swell?

Ask provider: Furosemide is often a critical part of keeping a heart with CHF in balance. Without it, there may be swelling, and usually with it, more shortness of breath. Not all CHF patients need a diuretic however, and excessive use may lead to dehydration or even worsening renal function. This is a question best asked of the provider that follows the patient regularly.
