What It Is and How It Works
Ivermectin is an antiparasitic medication that acts by binding to certain cell membrane proteins found in parasites, causing paralysis and death. This effectiveness makes it an invaluable tool in managing parasitic infections that commonly afflict cats. It is a derivative of avermectin, produced naturally by the bacterium Streptomyces avermitilis. While effective against numerous parasites, the precise action depends on the parasite type and the infection severity.
Indications / Uses
Ivermectin is primarily used for treating ear mite infestations, caused by Otodectes cynotis, and certain intestinal worms. It\’s often prescribed in cases where topical treatments for ear mites have not fully resolved the issue. In some instances, veterinarians may use ivermectin off-label to manage other types of infestations or conditions, though such uses must be carefully considered and monitored.
Dosage Forms and Typical Dosing Considerations
Ivermectin for cats is available in several forms, including topical solutions, oral tablets, and injections. The exact form and dosing depend on the specific condition being treated. Factors influencing dosing include the cat’s age, weight, overall health, and current medications. Because of its potency, precise dosing is critical to avoid toxicity. Always follow veterinarian instructions, as ivermectin dosing can vary significantly.
How to Take It Correctly Step-by-Step
Administration of ivermectin should follow these general guidelines, although specific instructions from a veterinarian should always take precedence:
- Administer the medication at the same time each day to maintain consistent levels in the system.
- If using a topical solution, ensure the cat’s skin is clean and dry before applying.
- For oral formulations, administer the drug with food if gastrointestinal upset occurs.
- Store ivermectin in a cool, dry place away from sunlight.
- Never double doses if a dose is missed; consult your veterinarian for guidance.
- Avoid using alcohol as it can interact and increase ivermectin’s effects.
