Edema
"I have been using Lasix in combination with Hydrochlorothiazide for 6 months for pitting edema/hypertension and it&#039;s effects seem to have worn off. I started on 20mg once a day for 2 months then up to 40mg once a day for the last 4 months. Now my legs are back to swelling as much as if I were taking nothing. My blood pressure is good though. Side effects, headaches."
