Comprehensive Parasite Protection: What Advantage Multi Does for Cats
Advantage Multi for Cats is a powerful, broad-spectrum, monthly prescription medication designed to protect felines from a variety of internal and external parasites. Combining two active ingredients—imidacloprid and moxidectin—this colorless to yellow topical solution offers a convenient, once-monthly treatment option for cat owners seeking a simplified but effective parasite control strategy.
Main Benefits of Advantage Multi
Advantage Multi is indicated for:
- Prevention of heartworm disease caused by Dirofilaria immitis
 - Elimination of adult fleas (Ctenocephalides felis)
 - Treatment and control of flea infestations
 - Treatment and control of ear mites (Otodectes cynotis)
 - Treatment and control of roundworms (Toxocara cati) and their fourth-stage larvae
 - Treatment and control of hookworms (Ancylostoma tubaeforme) in all stages up to fourth-stage larvae
 
How It Works
The unique combination of ingredients ensures both systemic and topical effectiveness:
- Imidacloprid (10%): An insecticide that kills adult fleas on contact before they bite
 - Moxidectin (1%): An anthelmintic effective against heartworm larvae, hookworms, roundworms, and ear mites
 
This dual-action approach ensures a comprehensive layer of protection for cats.
Correct Usage and Application
It is essential to follow the correct handling and dosage instructions:
- Remove one tube and hold upright.
 - Remove cap, reverse it, and twist it onto the tip to break the seal.
 - Part the hair on the back of the cat’s neck at the base of the head.
 - Place the tube’s tip directly on the skin and apply the entire contents.
 - Lift tube away before releasing pressure to avoid spillage.
 - Do not bathe the cat for at least 90 minutes post-application.
 
Note: Treating at the base of the head helps prevent oral ingestion due to grooming, and cats should not lick or groom each other for at least 30 minutes after treatment. Humans should also avoid contact with the site for this time and wash hands thoroughly afterward.
Dosage Guidelines
Advantage Multi is available in premeasured tubes depending on the cat’s weight:
- 2–5 lbs: 0.23 mL
 - 5.1–9 lbs: 0.4 mL
 - 9.1–18 lbs: 0.8 mL
 - Over 18 lbs: Combine appropriate dose tubes
 
Cats should be at least 9 weeks old and weigh a minimum of 2 lbs before treatment. The recommended monthly dosage: 4.5 mg/lb (10.0 mg/kg) of imidacloprid and 0.45 mg/lb (1.0 mg/kg) of moxidectin.
Safety and Precautions
- Do not use on sick, debilitated, or underweight cats
 - Only for use in cats over 9 weeks of age and weighing more than 2 lbs
 - Avoid applying to irritated skin
 - The product’s safety in pregnant, breeding, or lactating animals has not been fully evaluated
 
Important: If a dose is missed, apply as soon as possible and resume the monthly schedule. Do not double up on treatments.
Possible Side Effects
Mild and transient effects may occur, including:
- Agitation, pacing, spinning, or hiding
 - Excessive grooming at application site
 - Redness, hair loss, or scabbing at site

Always notify your vet of existing medications your cat is taking.
