Product Details

The introduction of this advanced worming paste means the war on worms has entered a new phase with a real-value, one shot wormer weapon that combats and controls all common internal worms. FARNAM® MECWORMA®‘s active ingredient increases the firepower against worms and bots whilst providing protection and treatment of summer sores.
The true easy-squeeze action takes the stress out of pasting, reducing wastage from misfires and finally provides horse carers with a paste that doesn’t require a commando’s grip.
Safe to use with all horses, including pregnant mares and foals, FARNAM® MECWORMA® can be used in rotation with FARNAM® WORMA DRENCH or FARNAM® WORMA PASTE.
  • Oral paste in dial a dose syringe.
  • Each g contains: ABAMECTIN 3.64 mg.
  •  FARNAM® MECWORMA® has been shown to be highly effective (up to 100% activity) in control and treament of large and small strongyles (Strongyles and Cyathastomum spp.) including arterial larval stages and benzimidazole resistant strains, bots (Gasterophilus spp.) cutaneous onchocerciasis and nematodes including Habronema and Draschia spp. which cause skin lesions (summer sores)
  • FARNAM® MECWORMA® contains abamectin, which is the only natural form of the macrocylic lactone group of anthelmintics. Macrocyclic lactone compounds have revolutionised the control of parasites in animals. They are generally regarded as the most effective, least toxic and non-carcinogenic parasiticides yet developed. The FARNAM® MECWORMA® paste is easy to administer under a wide range of conditions, with a sticky consistency that is well accepted with minimal wastage. Abamectin has a wide safety margin at the recommended dose level especially in foals, pregnant mares, and aged or debilitated horses. There has been no adverse effects reported when used at double the recommeneded doses on horses with a heavy parasite burden.
A complete syringe treats a 600 kg body weight horse. The plunger is calibrated in 100 kg weight increments which each deliver 5.5g of paste. Adjust the locking ring to the required body weight and depress plunger. Ensure paste is administered on the rear of the tongue and hold horse’s head raised for a few seconds after dosing to ensure the paste is swallowed.
