Dosage
Furosemide 40 mg Tablet-Edema:
- Adults: The initial adult dose is 40 mg daily, reduced to 20 mg daily or 40mg on alternate days. In some patients daily doses of 80mg or higher (given in divided doses) may be required. The individually determined single dose should then be given once or twice daily (eg, at 8 am and 2 pm). For resistant edema, 80-120 mg daily. In patients with clinically severe edematous states the dose of furosemide may be carefully titrated up to 600 mg/day. When doses exceeding 80 mg/day are given for prolonged periods, careful clinical observation and laboratory monitoring are particularly advisable.
- Children: Neonate: 0.5-2 mg/kg every 12-24 hours (every 24 hours if postmenstrual age under 31 weeks).
- Child 1 month-12 years: 0.5-2 mg/kg 2-3 times daily (every 24 hours if postmenstrual age less than 31 weeks); higher doses may be required in resistant edema; max. 12 mg/kg daily, not to exceed 80 mg daily.
- Child 12-18 years:20-40 mg daily, increased in resistant edema to 80-120 mg daily.
- Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.
- Adults: The usual initial dose of furosemide for hypertension is 80 mg, usually divided into 40 mg twice a day. Dosage should then be adjusted according to response. If response is not satisfactory, add other antihypertensive agents.
- Children: The usual dose is 1 - 3 mg/kg body weight daily up to a maximum dose of 40mg/day.
- Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.
Furosemide Syrup: Furosemide Liquid has an exceptionally wide therapeutic range, the effect being proportional to the dosage. Furosemide Liquid is best given as a single dose either daily or on alternate days. The usual initial daily dose is 40 mg. This may require adjustment until the effective dose is achieved as a maintenance dose. In mild cases, 20 mg daily or 40 mg on alternate days may be sufficient, whereas in cases of resistant edema, daily doses of 80 mg and above may be used as one or two daily, or intermittently. Severe cases may require gradual titration of the furosemide dosage up to 600 mg daily. The recommended maximum daily dose of furosemide administration is 1,500 mg.
