Bendroflumethiazide is a medication primarily used to treat high blood pressure and fluid retention (edema). It belongs to a class of drugs known as thiazide diuretics, which help the body eliminate excess salt and water through urine. This action can lower blood pressure and reduce swelling in conditions like heart failure or kidney disorders. Patients taking Bendroflumethiazide may experience side effects such as increased urination, dizziness, or electrolyte imbalances. It is important for individuals to follow their healthcare provider's instructions and have regular check-ups to monitor their response to the medication and any potential complications.
