Clinical information

Furosemide Tablets BP (Vet) 40 mg — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

For the treatment of oedema, the product may be used in ascites, hydrothorax,
pulmonary oedema of the mammary glands or legs, as well as oedema resulting
from cardiac insufficiency, hepatic or renal dysfunction, parasitism or of a
traumatic origin.

5mg/KgBW, one or two times per day. For patients weighing less than 8Kg
dosage with the 20mg tablet (which may be halved) is recommended. Avoid
overdosage in weak and old patients.

Do not use in acute glomerular nephritis, in electrolyte diseases, in patients with
anuria, or patients that have received excessive doses of cardiac glycosides.
Because of the danger of potentiating their toxic effects do not use with
aminoglycoside or cephalosporin antibiotics. Allergic reactions have been
associated with use with sulphonamides.

None Reported

The patient may increase its water intake to compensate for the diuresis.
Consideration should be given to restricting water intake if the patient’s condition
makes such a course appropriate.

Store in the original container in order to protect from light.

Prolonged dosage may on occasions justify potassium supplementation and
thus monitoring for hypokalaemia should be considered, especially if the product
is used in conjunction with cardiac glycosides.
4.5.2 Special precautions to be taken by the person administering the medicinal
product to animals:
Wear gloves or wash hands immediately after handling tablets. In case of
accidental ingestion seek medical attention and show product label and/or pack
insert to the doctor.
4.6 Adverse reactions
None Reported
4.7 Pregnancy and lactation
The safety of use in pregnancy is not well established and a careful assessment
of the likely benefits and potential risks should be made. A deleterious effect on
lactation is to be expected, particularly if drinking water is restricted. Furosemide
passes into milk, but not to a great extent.
4.8 Interactions
Potential interactions with other drugs include ototoxicity with aminoglycosides
and nephrotoxicity with cephalosporins. Use in combination with sulphonamide
treatment may lead to sulphonamide allergy. There is a possibility of interaction
with cardiac glycosides.
4.9 Amounts to be administered and administration route
5mg/KgBW, one or two times per day. For patients weighing less than 8Kg
dosage with the 20mg tablet (which may be halved) is recommended. Avoid
overdosage in weak and old patients.
4.10 Overdose
Dehydration and electrolyte depletion may occur. Monitor and correct as
necessary. Dosage higher than that which is recommended, may cause

transitory deafness. Cardiovascular side effects may be observed in weak and
old patients following overdose.
4.11 Withdrawal periods
Not applicable.
