Lasix 20 mg Tablets
Lasix® (furosemide) is a prescription medicine approved for the treatment of high blood pressure and water retention.
The recommended starting dose for treating high blood pressure is Lasix 40 mg twice daily. Based on how you respond to the medication, your healthcare provider may increase or decrease this amount as necessary. With each change in dosage, it may take several weeks to see the full effects of Lasix on blood pressure.
Adults being treated for water retention often start with 20 mg Lasix tablets, but may take up to 600 mg daily (taken either as a single dose or divided into several doses a day). Some people will only need to take the medication when they need it (when they are experiencing water retention), while others need to take it on a daily basis.
Lasix is licensed for treating water retention (but not high blood pressure) in children and infants. Usually, the starting dosage for infants and children is 2 mg per kilogram per day (about 0.9 mg per pound of body weight per day). The child's healthcare provider may increase the dose if needed, up to a maximum of 6 mg per kilogram (about 2.7 mg per pound).
