Panomec ivermectin is a broad-spectrum veterinary macrocyclic lactone parasiticide (1% injectable solution and oral equine paste) formulated specifically for swine, beef cattle, and non-lactating dairy cattle to eliminate internal roundworms, lungworms, and external ectoparasites; in swine, Panomec ivermectin is dosed subcutaneously in the neck at 300 micrograms per kilogram of body weight (1 mL per 33 kg / 73 lbs), requiring a mandatory 18-day meat withdrawal period before slaughter.
Agricultural herd health and commercial swine production rely heavily on pharmaceutical-grade avermectins to maximize feed conversion efficiency and eliminate debilitating mange mite infestations. Understanding the pharmacological profile, targeted parasite spectrum, and meat withdrawal intervals of Panomec ensures food safety and optimal herd biosecurity.
Spectrum of Parasitic Efficacy in Livestock
Panomec delivers systemic endectocidal activity against a comprehensive range of internal and external livestock parasites.
| Livestock Species | Targeted Internal Parasites (Nematodes) | Targeted External Parasites (Ectoparasites) | Approved Administration Route |
|---|---|---|---|
| Swine (Pigs & Sows) | Ascaris suum (large roundworms), Hyostrongylus rubidus, Oesophagostomum, Metastrongylus (lungworms) | Sarcoptes scabiei var. suis (swine mange mites), Haematopinus suis (sucking lice) | Subcutaneous (SC) injection in the neck (1 mL / 33 kg) |
| Beef Cattle | Ostertagia ostertagi (brown stomach worm), Cooperia, Haemonchus, Dictyocaulus viviparus (lungworm) | Psoroptes ovis (scabies), Hypoderma bovis (cattle grubs / warbles), sucking lice | Subcutaneous (SC) injection under the skin of the neck (1 mL / 50 kg) |
| Equines (Horses) | Large & small strongyles, pinworms (Oxyuris equi), ascarids, stomach bots (Gasterophilus) | Summer sores (Habronema microfilariae) | Oral Paste Formulation (0.2 mg/kg calibrated syringe) |
Dosing Guidelines & Subcutaneous Administration Technique
Livestock veterinarians outline strict technical steps for administering 1% injectable Panomec:
- Weight Calibration: Accurately weigh animals or use an agricultural weigh tape before calculating dose volumes to avoid underdosing (which accelerates drug resistance) or toxic overdosing.
- Aseptic Subcutaneous Injection: For swine, inject subcutaneously into the loose skin immediately behind the ear using a sterile 16-to-18 gauge, 1/2-inch to 3/4-inch needle. For cattle, inject under the loose skin in front of the shoulder.
- Divided Injection Sites: If the total calculated volume exceeds 10 mL in cattle, divide the dose across separate injection sites to minimize localized tissue irritation.
- Breeding Herd Protocols: Treat breeding sows 7 to 14 days prior to farrowing to prevent transmitting mange mites and roundworms to newborn piglets during nursing.
Mandatory Meat Withdrawal & Safety Precautions
To comply with agricultural food safety regulations and prevent chemical residues in the commercial meat supply:
- Swine Meat Withdrawal (18 Days): Do not slaughter treated pigs for human consumption within 18 days of the last injection.
- Cattle Meat Withdrawal (35 to 49 Days): Beef cattle require a minimum 35 to 49-day withdrawal window (refer to specific regional product labeling).
- Lactating Dairy Animals: Not approved for use in female dairy cattle of breeding age producing milk for human consumption.
- Proper Disposal: Avermectins are toxic to aquatic organisms and dung beetles; dispose of empty vials, syringes, and unused solution in accordance with environmental agricultural regulations.
Comparative Pharmacokinetics & Hepatic Clearance Dynamics
Understanding tissue clearance kinetics assists veterinary clinicians in determining appropriate re-treatment intervals. Avermectins undergo hepatic microsomal oxidation before biliary excretion, maintaining prolonged parasite suppression across therapeutic windows.
Veterinary Pharmacology Summary & Herd Health Guidelines
Panomec provides reliable broad-spectrum parasite eradication. Implement structured fecal egg count surveillance and rotate antiparasitic chemical classes annually to prevent drug resistance.
Comparative Pharmacokinetics & Safety Monitoring Standards
Understanding drug clearance pathways assists clinicians and agricultural producers in determining appropriate dosing intervals. Macrocyclic lactones undergo hepatic microsomal biotransformation via cytochrome P450 enzymes before biliary elimination, providing sustained anthelmintic and ectoparasiticidal coverage across therapeutic windows.
Global Regulatory Standards & Clinical Collaboration
Collaborative decision-making between healthcare providers, pharmacists, veterinarians, and animal caretakers ensures treatment regimens are individualized, monitored for safety, and adjusted over time to achieve sustained symptom resolution.
Frequently Asked Questions (FAQ)
Can you inject Panomec intramuscularly (IM) or intravenously (IV)?
No. Panomec 1% injectable is formulated strictly for subcutaneous (under the skin) injection; IV injection can cause acute neurotoxicity and cardiovascular collapse.
Can Panomec be given to sheep and goats?
While veterinarians sometimes use 1% ivermectin off-label in small ruminants, goats metabolize avermectins faster and require specialized veterinary dose adjustments.
How does Panomec cure mange in pigs?
Panomec reaches high concentrations in the skin, paralyzing feeding Sarcoptes scabiei mites and halting skin crusting and ear scratching within 7 to 14 days.
Can humans use Panomec veterinary dewormer?
No. Veterinary injectable products contain carrier solvents and concentrations unsafe for human use. Humans must only take regulated pharmaceutical tablets.
