Description
Revolution Plus Topical Solution for Cats 5.6-11 lbs (2.6-5 kg) is a dual-active spot-on formulation combining selamectin and sarolaner, produced by Zoetis, that addresses seven parasite categories in a single monthly application. The orange-cap pipette delivers selamectin 30 mg and sarolaner 5 mg per dose, calibrated to the 2.6–5 kg body weight range. No oral administration is involved, which makes this variant practical for cats that refuse tablet or chewable formats.
Recommended for
Cats and kittens weighing 5.6–11 lbs (2.6–5 kg) from 8 weeks of age.
Indication/Coverage
For cats suffering from, or at risk from, mixed parasitic infections, Revolution Plus 5.6–11 lbs covers the following indications:
- Flea treatment and prevention (Ctenocephalides felis, adults): Kills adult fleas on the treated cat before egg deposition occurs, reducing both on-animal infestation and environmental flea burden over time.
- Tick treatment and control (Ixodes scapularis, Amblyomma americanum, Amblyomma maculatum, Dermacentor variabilis, adults): Sarolaner distributes systemically and kills attached ticks across four species of clinical significance in North America.
- Heartworm prevention (Dirofilaria immitis, L3/L4 larvae and immature adults): Monthly selamectin dosing eliminates infective larvae acquired during the preceding 30 days and clears immature adult stages that developed following initial larval exposure.
- Roundworm treatment (Toxocara cati, intestinal adults): A single topical dose clears established intestinal roundworm infections; ongoing monthly administration maintains worm-free status.
- Intestinal hookworm treatment (Ancylostoma tubaeforme, intestinal adults): Selamectin eliminates hookworm infections with a single application; monthly continuation prevents reestablishment.
- Ear mite treatment (Otodectes cynotis, adults): Administered as a single dose at the base of the neck, not into the ear canal directly; monthly use controls recurrence of infestation.
- Tapeworm prevention (Dipylidium caninum): Prevention is indirect, achieved by eliminating Ctenocephalides felis vector fleas on the treated cat and thereby breaking the primary transmission route for caninum.
Key Benefits
The following properties are drawn directly from the Revolution Plus label and field safety data for the 5.6–11 lbs orange-cap variant:
- Eligible from 8 weeks: The labeled minimum age matches the 2.8–5.5 lbs variant, so kittens that graduate into this weight band during the normal growth period can continue without interruption to their preventive schedule.
- Simultaneous seven-parasite coverage: One pipette addresses fleas, four tick species, heartworm larvae, roundworm, hookworm, ear mites, and tapeworm (via flea control), eliminating the need to coordinate multiple single-target products.
- Dual-class mechanism: Selamectin disrupts neurotransmission in parasites by interfering with glutamate-gated chloride channel conductance, while sarolaner (an isoxazoline) blocks GABA- and glutamate-gated chloride channels. These complementary mechanisms provide broad-spectrum activity against both ectoparasites and endoparasites.
- Pre-oviposition flea kill: Adult fleas are eliminated on the treated cat before laying eggs, which curtails household environmental contamination and limits the flea life cycle at its source.
- Continuous heartworm barrier: Each dose covers the full 30-day interval between applications, provided the schedule is maintained without gaps exceeding one month.
- Topical delivery: Dermal absorption at the base of the neck bypasses the gastrointestinal tract entirely, which is clinically relevant for cats with documented food aversions, pill refusal, or post-oral vomiting histories.
- Water Resistance: Avoid bathing or shampooing the treated cat for 24 hours after application, as this may decrease selamectin efficacy. After absorption, the product maintains its effectiveness despite water exposure.
Caution
Hazards to Humans
Revolution Plus contains isopropyl alcohol and butylhydroxytoluene, both of which irritate skin and eyes on contact. Wash hands with soap and water after handling. Flush eyes thoroughly if accidental contact occurs. Keep children away from treated cats for 4 hours post-application and store all pipettes out of their reach.
Hazards to Domestic Animals
Revolution Plus 5.6–11 lbs is for external use on cats only; do not apply to dogs or other species. This variant is labeled for cats weighing 5.6–11 lbs (2.6–5 kg) from 8 weeks of age. Safety in breeding, pregnant, or lactating cats has not been established in published studies; veterinary assessment is warranted before initiating treatment in these animals. Sarolaner is an isoxazoline-class compound, a drug class linked to neurologic adverse reactions including tremors, ataxia, and seizures, reported even in cats without a prior neurologic history; evaluate individual risk before the first dose.
Possible Side Effects:
Monitor your cat closely during the 2 hours following application and for the remainder of the treatment day.
- Application site reactions (selamectin, topical): Transient stiff hair, fur clumping, discoloration, or a light powdery residue at the base of the neck may appear after the product dries. These effects are self-limiting and carry no impact on the dose’s systemic efficacy.
- Dermal irritation (sarolaner, topical): Localized pruritus, erythema, or skin sensitivity at or near the application site has been reported. Signs typically resolve without treatment within 24 to 48 hours.
- Gastrointestinal signs: Hypersalivation or vomiting may follow if the cat accesses and grooms the application site before the product has dried. Do not allow the cat to lick the application site until the treatment has fully dried.
- Neurologic signs (isoxazoline class): Tremors, incoordination, or seizure activity are potential adverse effects of sarolaner in susceptible cats, including those with no prior history of neurologic disorders. Discontinue use immediately and seek veterinary attention if any of these signs emerge.
If adverse reactions are observed or worsen after the first application, consult a veterinarian.
