Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Levacur SC 3% is a broad spectrum anthelmintic for the treatment and control of
gastro-intestinal and pulmonary nematode infections in cattle and sheep.
Levacur SC 3% is effective against mature and developing immature stages of
the following levamisole-susceptible major nematode worm species:-
Gastro-intestinal Worms:
Trichostrongylus spp.,
Cooperia spp., Ostertagia spp. (except inhibited
Ostertagia larvae in cattle), Haemonchus spp.,
Nematodirus spp., Bunostomum spp.,
Oesophagostomum spp., Chabertia spp.

Revised: November 2025
AN: 02376/2025
Lungworms: spp.
Levacur SC 3% is not effective against Type II Winter scour.
The product also contains Selenium and Cobalt as nutritional supplements.

Ruminating cattle over two months of age and weighing over 100 kg body weight:
2 boluses.
Administer orally using an oesophageal balling-gun, which delivers the bolus directly into
the top of the gullet. Great care should be taken not to cause any injury by rough handling
or by placing the gun too far inside the throat of the animal. Ensure that each animal has
swallowed the boluses by holding the mouth closed and observing the animal for a short
time after dosing. Gentle massage of the throat may facilitate swallowing of the boluses.
The boluses should normally be administered just before turnout, but administration may
be carried out at any time, e.g. administer to dairy cows at drying off or at calving or 30
days post-calving or at artificial insemination.
The boluses are sensitive to sudden temperature changes such as those that may occur
when very cold boluses are swallowed by an animal. Therefore, it is important that the
bolus is at room temperature (15 – 20
o
C) prior to administration to prevent the
development of fine cracks that may change the activity of the bolus.
To minimise the risk of regurgitation, avoid rough handling of animals after dosing.
Do not administer the recommended dosage to animals more frequently than once every
4.5 months to animals receiving concentrates or every 6 months to cattle at pasture.

Do not administer to non-ruminating calves or to animals weighing less than 100 kg body
weight.
Do not administer to sheep.
See also Section 3.5, Special precautions for use.
Do not use in cases of hypersensitivity to the active substance(s), or to any of the
excipients.

None known.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder <or its local representative> or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.

The veterinary medicinal product is not intended for treatment of acute clinical conditions
such as nutritional muscular dystrophy.

Special precautions for safe use in the target species:
Prior to supplementation with any form of copper or selenium, it should be demonstrated
that there is a need for extra trace elements to be given to the animals.
Additional copper should not be administered orally or by injection, or selenium by
injection, within six months after administration of the veterinary medicinal product to cattle
at pasture or within 4.5 months in cattle where the diet is supplemented with concentrates
unless subjected to a risk/benefit analysis performed by a responsible veterinarian in each
case.
Do not administer any aids to alter dissolution of the bolus.
The boluses are sensitive to sudden temperature changes such as those that may occur
when very cold boluses are swallowed by an animal. Therefore it is important that the
bolus is at room temperature (15 – 20
o
C) prior to administration to prevent the
development of fine cracks that may change the activity of the bolus.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
