Description
Nitromec Injection Endectocide and Flukicide for Cattle treats liver fluke, roundworms and external parasites in a single subcutaneous injection. Specifically, each litre contains 340 g/L nitroxynil (as eglumine), 67 g/L clorsulon and 6.7 g/L ivermectin. Virbac (Australia) Pty Limited also registered this Nitromec flukicide injection for cattle under APVMA number 59844/122002.
The label claims control of nitroxynil-, ivermectin-, and clorsulon-sensitive strains of internal and external parasites. In addition, it covers triclabendazole-resistant liver fluke, including early immature fluke from two weeks old. As a result, producers can treat fluke, worms, lice and cattle ticks in one handling.

Dose each group by its heaviest animal. First, weigh a representative sample. Then inject under the skin, preferably high on the neck behind the ear. Use the shortest sharp needle possible, because needles must not exceed 15 mm.

Virbac’s FlukeKill Programme times fluke treatments for autumn and spring. It also adds a third treatment in summer when infection is heavy. Furthermore, because Nitromec controls triclabendazole-resistant fluke, it gives you another drench family to rotate.
Frequently asked questions
Q. What does Nitromec Injection control in cattle?
A. Nitromec controls liver fluke, roundworms, lungworm and eyeworm. It also treats sucking lice, mites and cattle tick. However, these claims apply only to sensitive strains of the parasites.
Q. What is the Nitromec dose rate for cattle?
A. The dose is 1.5 mL per 50 kg liveweight by subcutaneous injection. For example, a 300 kg animal needs 9 mL. Therefore, dose each group by its heaviest animal and do not underdose.
Q. Can I use Nitromec on heifers I plan to milk later?
A. No, the label bans use in any cattle that may in the future produce milk for human consumption. As a result, milk from a treated heifer can never legally go to human consumption. Instead, choose a different flukicide for dairy replacements.
Q. What are the Nitromec withholding period and ESI?
A. The meat withholding period is 56 days, and the export slaughter interval is 120 days. Likewise, calves born to treated cows follow the same intervals, counted from the dam’s treatment. Confirm the current ESI with Virbac on 1800 242 100 before use.
Q. How soon can I re-treat cattle with Nitromec?
A. Do not re-treat cattle for 120 days after the last treatment. The label sets this interval, so follow it exactly. Therefore, check your treatment records before each dose.
