Primisol 50

Primisol 50 is a potent broad-spectrum anthelmintic specially formulated to treat and control gastrointestinal and respiratory nematodes in poultry and livestock. With Levamisole hydrochloride as its active ingredient, it is highly effective against common parasitic worms and the fowl eye worm, offering rapid parasite clearance and improved health performance.

Levamisole hydrochloride – 500 mg per gram

  • Gastrointestinal roundworms (Ascaridia galli, Heterakis gallinarum)

  • Capillaria obsignata infections

  • Lungworms

  • Fowl eyeworm (Oxyspirura mansoni)

  • Other nematode infestations in poultry and ruminants

Levamisole acts as a cholinergic agonist, stimulating the parasite’s nerve ganglia and muscle membrane receptors, resulting in paralysis and expulsion from the host. It also enhances immune function, making it especially effective in fighting off parasite reinfestation.

  • Poultry (general deworming): 1 g in 2–3 liters of drinking water over 12 hours

  • Fowl eyeworm: Use a 10% solution; apply a few drops directly into the eye—parasite is eliminated within 1 hour

  • Cattle, buffalo, sheep, goats: 1 g per 25–50 kg body weight, administered via drinking water

  • General dose range: 36–48 mg per kg body weight

  • Rapid-acting anthelmintic with broad efficacy

  • Effective against both intestinal and lung nematodes

  • Specialized treatment for fowl eyeworm with local application

  • Enhances immune response against parasites

  • Water-soluble formulation ensures convenient mass dosing
