Zolvix Monepantel 2.5ltr



Product Type

Oral broad spectrum anthelmintic for the treatment of gastrointestinal roundworms in sheep.
ZOLVIX® is a ready-to-use, low-volume oral drench for sheep.


ZOLVIX is from the first and only new broad spectrum class of sheep drench since the 1980s. With a unique mode of action, ZOLVIX offers unparalleled levels of certainty in worm control.

When used in appropriate rotation, ZOLVIX can minimise the development of resistance to other existing drench actives.1 It protects and promotes animal health while boosting productivity.2 ZOLVIX also has an impressive safety profile with no detrimental effects on sheep, people or the environment.3

Several years of field tests conducted on commercial farms in Australia, New Zealand and Europe confirmed the effectiveness of ZOLVIX. The in-field trials included farms with resistance to all three older broad-spectrum drench classes.

The active ingredient in ZOLVIX is monepantel, the first member of the amino-acetonitrile derivatives (AADs) or ‘orange’ drench class. Monepantel has a unique mode of action compared with all other available anthelmintics. Monepantel causes paralysis in worms by binding to a specific receptor found only in nematodes (roundworms). The specific receptor for the AADs has not been found in any animal species – and this is believed to be the reason behind the high margin of safety in sheep and environmental safety.

Dosage and Administration

The recommended dose rate is:

  • 1mL per 10kg body weight (corresponding to 2.5mg monepantel per kg) for the treatment and control of AAD-sensitive strains of gastrointestinal roundworms, including macrocyclic lactone, benzimidazole, levamisole and morantel-resistant strains, in sheep in Australia.

Effective worm kill depends on correct and accurate dosing. Follow the dose instructions on the label closely.

Give a full dose orally according to the dosing table. Check the accuracy of the drenching gun before and during use. To ensure effective worm kill, NEVER underdose any animal.

A representative sample of animals should be weighed before treatment. Dose the mob to the heaviest animal in each group (ewes, rams, lambs, etc.). Where there is a large variation in size within the group, dose rate should be based on the label directions for each weight range. Drafting into two or more lines may be appropriate, to avoid excessive overdosing.

Administration with the ZOLVIX Optimum™ Delivery System (featuring the Optiline® drencher and Optivix® backpack) is recommended. This system was designed and tested by farmers to ensure drenching is accurate, faster, easier and less tiring to the operator.
