|Uses:||The uses of Lasix Oral Soln include:|
Lasix is indicated in adults, infants and children for the treatment of oedema associated with congestive heart failure, cirrhosis of the liver and renal disease including the nephrotic syndrome. Lasix is particularly useful when an agent with greater diuretic potential than that of those commonly employed is desired. Parenteral therapy should be reserved for patients unable to take oral medication or for patients in emergency clinical situations.
Lasix Injection is also indicated as adjunctive therapy in acute pulmonary oedema and cerebral oedema where intense and rapid onset of diuresis is desired. If gastrointestinal absorption is impaired or oral medication is not practical for any reason, Lasix is indicated by the intravenous route. Parenteral use should be replaced with oral Lasix as soon as practical.
Oral Lasix may be used in adults for the treatment of hypertension alone or in combination with other antihypertensive agents. Hypertensive patients who cannot be adequately controlled with thiazides will probably also not be adequately controlled with Lasix alone.
DOSAGE AND ADMINISTRATION
Lasix Oral Administration
Therapy should be individualised according to patient's response. This therapy should be titrated to gain maximal therapeutic response with the minimum dose possible to maintain that diuretic response.
Adults: The usual initial daily dose is 20 to 80 mg given as a single dose. If the diuretic response to a single dose of 20 to 80 mg is not satisfactory, increase this dose by increments of 20 to 40 mg, not sooner than 6 to 8 hours after the previous dose, until the desired diuretic effect is obtained. This individually determined dose should be given once or twice (e.g. at 8 am and 2 pm) daily. The dose of Lasix may be carefully titrated up to 400 mg/day (except in advanced renal failure) in those patients with severe clinical oedematous states. The mobilisation of oedema may be most efficiently and safely accomplished by giving Lasix on 2 to 4 consecutive days each week.
When doses exceeding 80 mg/day are given for prolonged periods, careful clinical laboratory observations are particularly advisable.
Infants and Children: The usual initial dose of oral Lasix for infants and children is 2mg/kg body weight given as a single dose. If the diuretic response is not satisfactory, the dose may be increased by 1 to 2 mg/kg no sooner than 6 to 8 hours after the previous dose. Doses of greater than 6 mg/kg body weight are not recommended.
For maintenance therapy in infants and children, the dose should be adjusted to the minimum effective level.
Therapy should be individualised according to the patient's response. This therapy should be titrated to gain maximal therapeutic response with the minimum dose possible to maintain that therapeutic response.
Adults: The usual initial daily dose of Lasix 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.
Changes in blood pressure must be carefully monitored when Lasix is used with other antihypertensive drugs, especially during initial therapy.
To prevent an excessive drop in blood pressure, the dosage of other agents should be reduced by at least 50% when Lasix is added to the regimen. As the blood pressure falls under the potentiating effect of Lasix, a further reduction in dosage or even discontinuation of other antihypertensive drugs may be necessary.
