High Blood Pressure
The recommended starting dosage for the treatment of high blood pressure is 40 mg twice daily (for a total 80 mg of Lasix per day). Based on the initial blood pressure response and/or side effects, your healthcare provider may increase or decrease this amount as necessary. With each dosing change, it may take several weeks to see the full effects of this medication on blood pressure.
The recommended dose of Lasix for treating fluid retention can vary between 20 mg and 600 mg daily (taken as a single dose or divided and taken more frequently). Some people will only need to take it when they experience water retention, while others will need to take the medication on a daily basis.
