Buy Ivomec Gold 50ml Injection Online: The Definitive Veterinary Guide to Long-Acting 3.15% Ivermectin Therapy and Parasite Control in Cattle

In commercial beef and dairy production, systemic and external parasite infestations are a constant threat to herd health, daily weight gains, and overall reproductive efficiency. Gastrointestinal roundworms, lungworms, sucking lice, mange mites, and ticks cause persistent metabolic stress, tissue damage, and transmit costly blood-borne diseases.

Traditional 1% ivermectin formulations provide effective immediate clearance but require frequent re-administration due to their short therapeutic window. This frequent handling increases operational labor, raises cattle stress levels, and leaves animals vulnerable to rapid reinfection on contaminated pastures.

To overcome these production bottlenecks, progressive livestock managers rely on Ivomec Gold (manufactured by Boehringer Ingelheim). Featuring a highly concentrated 3.15% m/v Ivermectin suspended in a specialized, slow-release injection matrix, Ivomec Gold acts as a long-acting endectocide. A single low-volume subcutaneous dose delivers continuous, therapeutic blood levels that control internal and external parasites for extended periods.

This comprehensive clinical guide details the molecular biology, target parasitology, precise on-farm dosing protocols, and strict agricultural withdrawal windows for Ivomec Gold 50ml.

1. Molecular Biology and Pharmacological Mechanism of Action

Ivermectin belongs to the macrocyclic lactone (avermectin) class of highly potent, broad-spectrum antiparasitic agents.

Selective Binding to Glutamate-Gated Chloride Channels

At the molecular level, ivermectin targets the nervous and neuromuscular systems of nematodes (roundworms) and arthropods (ticks, mites, and lice). It binds with high affinity to glutamate-gated chloride channels located on the post-synaptic membranes of invertebrate nerve and muscle cells.

• Continuous Chloride Influx: This binding action keeps the chloride channels open, causing a steady, uncontrolled influx of negatively charged chloride ions into the nerve and muscle cells.

• Hyperpolarization: The influx of chloride ions hyperpolarizes the cell membranes, preventing them from transmitting normal electrical impulses.

• Flaccid Paralysis: Lacking neuromuscular coordination, the parasite undergoes flaccid paralysis. Unable to feed or maintain its position in the host’s body, the parasite dies and is naturally expelled.

The 3.15% Long-Acting Depot Technology

Standard 1% ivermectin formulations dissolve and clear from the body within a few days. Ivomec Gold features a specialized 3.15% m/v concentration suspended in a viscous, non-aqueous carrier vehicle.

Upon subcutaneous injection, this formulation forms a slow-release “depot” in the connective tissue. The active ivermectin is released gradually into the bloodstream over several weeks, keeping drug levels above the minimum therapeutic threshold to prevent reinfection.

2. Spectrum of Activity: Targeted Parasites

Ivomec Gold 50ml provides extended-duration control against several costly internal and external parasites:

Gastrointestinal Nematodes (Roundworms)

• Wireworm (Haemonchus placei)

• Brown Stomachworm (Ostertagia ostertagi, including inhibited larval stages)

• Cattle Bankruptworm (Cooperia species)

• Nodular Worm (Oesophagostomum radiatum)

• Lungworm (Dictyocaulus viviparus)

• Eyeworm (Thelazia species)

External Parasites & Ectoparasiticides

• Blue Ticks (Rhipicephalus / Boophilus microplus): Controls infestations and prevents pasture re-seeding for up to 75 days.

• Screwworm (Chrysomya bezziana): Kills active larvae present at injection and protects against screwworm strike for 14 days.

• Mange Mites (Psoroptes ovis, Sarcoptes scabiei var. bovis).

• Sucking Lice (Linognathus vituli, Solenopotes capillatus).

4. Clinical Safety, Contraindications, and Withdrawal Periods

Due to the long-acting carrier matrix and high 3.15% concentration, strict adherence to withdrawal periods is vital for food safety:

• Meat/Slaughter Withdrawal: Cattle must not be slaughtered for human consumption within 105 to 122 days of the last treatment (verify specific local requirements on your label package).

• Milk Withholding Time: Do not administer to lactating dairy cows whose milk is intended for human consumption. Do not use in dairy heifers or dry cows within 105 days prior to calving.

• Injection Site Swelling: Some animals may experience mild, transient soft-tissue swelling at the injection site. This is a normal localized reaction to the viscous carrier and typically resolves without veterinary intervention within a few days.

• Clostridial Vaccination: Because accidental tissue contamination during injection can introduce soil-borne pathogens, it is strongly recommended that cattle be fully vaccinated against Clostridial infections (such as Black Quarter) prior to mass treatment.

5. Frequently Asked Questions (FAQ)

What is the difference between standard Ivomec 1% and Ivomec Gold?

Standard Ivomec 1% contains 10mg of ivermectin per mL and is designed for short-term parasite clearance. Ivomec Gold contains 31.5mg of ivermectin per mL (3.15%) suspended in a slow-release carrier, providing extended-duration protection—such as up to 75 days of continuous control against blue ticks.

Can Ivomec Gold be injected into muscles (intramuscularly)?

No. Ivomec Gold is formulated specifically for subcutaneous (under the skin) injection only. Intramuscular or intravenous injection can alter how the drug is absorbed, leading to reduced efficacy, severe tissue irritation, or adverse reactions.

Is Ivomec Gold safe to use in pregnant breeding cows?

Yes. Ivomec Gold is safe for use in breeding animals and pregnant beef cows. However, do not use it in pregnant dairy cows within 105 days of calving if their milk is intended for human consumption.

How should the 50ml bottle be stored?

Store the vial upright in its original outer carton to protect it from direct sunlight, in a cool, dry place below 25°C. Protect from freezing, and keep it safely out of reach of children and animals.

6. Sourcing Genuine Ivomec Gold from Global Vet Care

At Global Vet Care, we understand that maintaining herd health requires premium, dependable veterinary supplies. Every vial of Ivomec® Gold 50ml is sourced directly through official manufacturer channels and kept in our temperature-controlled facility to guarantee absolute sterility and full therapeutic potency.

Ivomec Gold  has a thixotropic formulation and is a 315% solution of Ivermectin MERIAL indicated for treatment control and effective prevention of infections caused by roundworms tick.

Ivomec  Gold has a thixotropic formulation and is a 315% solution of Ivermectin MERIAL indicated for treatment control and effective prevention of infections caused by roundworms tick infestation lice sucking lice mites that cause sarcoptic and psoroptic mange of cattle. Ivomec Gold also helps control chewing lice – Bovicola (Damalinia) bovis – and mites that cause chorioptic mange. Ivomec Gold was developed to combine an effective antiparasitic control over established infections / infestations with a preventive antiparasitic effect for up to 8 weeks on round gastrointestinal and pulmonary worms for up to 75 days against the tick and up to 12 weeks on the berne. Ivomec Gold has a unique and patented manufacturing methodology.
Ivermectin immobilizes parasites inducing tonic paralysis of their muscles. This effect occurs due to the stimulus of the opening of chlorine channels existing in the nervous synapses of round worms and in the plaques or neuromuscular buds in arthropods controlled by glutamic acid and GABA (gamma-aminobutyric acid). As a result of the paralysis the parasites die and are eliminated.

Presentation of Ivomec Gold:

Polyethylene vial containing 1,000 mL closed with a perforable rubber stopper sealed with an inviolable aluminum seal and packed in cardboard boxes.

Ivomec® Gold is a formulation of high efficiency mainly when inserted in a Program of Integrated and Strategic Control of parasites that aims to avoid as much as possible the parasite-host contact preventing infection / infestation and consequently the damages caused by the parasitism. The preventive use of the product is preferable to the only curative use of parasitic infections / infestations since its prophylactic characteristics make it more efficient and with greater return when used strategically.
The recommended dose is 1 mL for every 50 kg of weight administered subcutaneously in front of or behind the palette. Use a sterile 16 gauge needle 15 to 20 mm long. Use aseptic procedures in the application. The product bottle should be shaken before application.

Slaughter: cattle treated with Ivomec Gold can only be slaughtered after 140 days from the date of the last treatment when the meat is intended for human consumption.
Milk: Ivomec  Gold should not be applied to lactating cows.

• Shake the bottle before use.
• Apply only by subcutaneous injection.
• Do not use in dairy cows.
• Empty packaging must be destroyed by incineration and never reused or washed in rivers or weirs.
• Avoid smoking or eating during handling.
• Wash hands after handling.
• Keep this and other medicines out of the reach of children and pets.
• Store away from light in a dry and cool place.

Benefits of Ivomec Gold:

• Greater weight gain anticipating the age of slaughter and the entry of animals into reproduction.
• Pastures that are cleaner for longer by roundworm larvae when Ivomec  Gold is used in an Integrated Strategic Parasitic Control Program for cattle.
• Time and labor savings in tick control: Ivomec  Gold keeps the bovine tick under control within the expected percentage (95% to 99%) for up to 75 days after application. Ivomec  Gold significantly affects the reproductive potential of tick females that eventually escape treatment by decreasing the egg laying of the parasite and affecting the hatching of these eggs which over time reduces pasture infestation and reinfestation rates. Due to an efficient preventive control of the tick, less infestation is expected, greater weight gain, better quality leather and reduction of diseases transmitted by the tick.
• Time and labor savings.
• High positive cost-benefit correlation.
• Compatibility with the different types of management normally used on the farm.
• Environmental safety: the Ivermectin eliminated with the feces of the treated animals becomes practically inert in the environment. Photodegradation by sunlight as well as oxidation gradually and rapidly decrease drug concentrations
