selamectin dosing for rabbits, vet-led

updated 19 May 2026

in Singapore, rabbit owners face a particular challenge when it comes to parasites. the heat and humidity, hovering around 28 to 32°C with 70 to 90% relative humidity year-round, create near-ideal conditions for mites and fleas to thrive. even indoor rabbits in HDB flats are not automatically protected. mites can arrive on imported hay, second-hand enclosures, new bedding, or other pets sharing the same space. once established, a mite infestation spreads quickly here because there is no cold season to slow parasite reproduction cycles. selamectin, sold internationally under the brand name Revolution, is one of the most commonly prescribed antiparasitic treatments for rabbits in Singapore. it is applied as a topical spot-on, not an injection or oral medication. but here is the critical point: selamectin is not licensed for rabbits. it is used off-label, which means dosing must always be vet-led. this guide explains the process from diagnosis to follow-up.

what is selamectin and how vets use it for rabbits

selamectin belongs to a class of antiparasitic drugs called avermectins. it disrupts the nervous systems of parasites, effectively paralysing and killing them, without causing the same effect in mammals at appropriate doses. for cats and dogs, selamectin is a fully licensed product with manufacturer-set dosing guidelines. for rabbits, no such guidelines exist from the manufacturer. SG exotic vets draw on peer-reviewed veterinary literature, rabbit-specialist guidelines, and clinical experience to determine what is appropriate for each individual animal. the dose depends on your rabbit’s body weight, current health status, and the specific parasite being targeted. the drug is applied as a small liquid drop at the back of the neck, in a spot your rabbit cannot easily reach to lick. your rabbit does not swallow anything. this matters because rabbits have a digestive system that is sensitive to stress and cannot vomit, making oral medications higher-risk in anxious animals.

which parasites selamectin targets

selamectin is broadly effective against several external parasites that commonly affect rabbits in Singapore. ear mites, caused by Psoroptes cuniculi, are the most frequently treated condition. these mites live in the ear canal and produce a thick, dark, crusty build-up that is intensely uncomfortable and painful for your rabbit. if left untreated, the infection spreads deeper and can cause permanent damage to the inner ear. fur mites, including Cheyletiella species, are another common target. this infestation is sometimes called ‘walking dandruff’ because the mite bodies are visible moving through the fur. affected rabbits often have flaky skin and may scratch frequently along the back and shoulders. fleas are less common in fully indoor SG rabbits but do occur, especially in homes with cats or dogs that go outdoors. selamectin can also be used against certain mite species affecting the skin more broadly, though these presentations vary. your vet will confirm which parasite is present before prescribing.

finding the right vet in Singapore

not every veterinary clinic in Singapore is equipped to treat rabbits. the country has a reasonable number of general practice clinics for cats and dogs, but rabbit-experienced exotic vets are fewer and more spread out geographically. a vet who is unfamiliar with rabbit physiology may misdiagnose the parasite, prescribe an inappropriate product, or calculate an incorrect dose. before your first appointment, ask the clinic directly whether they regularly see rabbits and whether they have experience with antiparasitic treatments in exotic small animals. as of 2026, a first exotic vet consultation in Singapore typically costs between SGD 50 and SGD 120, not including diagnostic tests like skin scrapes or ear microscopy. some clinics charge additional fees for examination under an otoscope. these costs are higher than a standard cat or dog consult, which reflects the additional expertise required. plan for this expense rather than trying to self-medicate to avoid it.

the vet consultation: what to expect

when you bring your rabbit in for a suspected parasite infestation, the vet will start by weighing your rabbit. this is not a formality: selamectin dosing is weight-dependent, and an incorrect amount can cause toxicity or be ineffective. the vet will then examine your rabbit’s ears using an otoscope and may take a skin scrape to confirm which parasite is present under a microscope. this diagnostic step matters. ear debris can look similar whether it is caused by mites, wax build-up, a bacterial infection, or a yeast problem. treating for mites when the real cause is bacterial means your rabbit gets the wrong treatment and continues to suffer. once the parasite is confirmed, the vet will apply selamectin directly or dispense it with clear instructions on frequency and follow-up. do not buy Revolution from a pet shop, pharmacy, or online marketplace and apply it yourself without vet guidance. the feline and canine formulations are significantly more concentrated than what a rabbit requires.

SG climate and ongoing parasite risk

Singapore’s climate means parasite management is rarely a one-time event. in countries with cold winters, mite populations naturally decline during colder months. here, mite reproduction continues year-round without any seasonal pause. an infestation that seems mild in January can escalate significantly by March if the environment is not addressed alongside the medical treatment. hay is one of the most common vectors for mite introduction in SG rabbits. timothy hay, orchard grass, and other imported hay products are not sterile. mite eggs or larvae can survive inside sealed bags under certain storage conditions. this does not mean you reduce your rabbit’s hay intake. hay is essential for gut motility and dental health. it means storing hay in a cool, dry spot away from high-humidity areas and monitoring your rabbit’s coat and ear canals regularly for early signs of trouble. HDB residents should also note that shared corridors and adjacent units with outdoor pets can occasionally introduce fleas into your home.

after treatment: what to monitor

after selamectin is applied, the application site should remain dry for at least 24 hours. if you have a bonded pair, separate them temporarily to prevent cross-grooming of the neck area during that window. mild lethargy on the first day after application is not unusual. what you need to watch more closely are signs of an adverse reaction: tremors, excessive drooling, loss of balance, or unusual seizure-like activity. if you notice any of these, take your rabbit to an emergency exotic vet immediately. do not wait to see if it resolves on its own. in Singapore, after-hours exotic vet access is limited compared to standard cat-and-dog emergency clinics. it is worth identifying which clinics in your area offer after-hours or weekend services before you need them urgently. your vet will tell you whether a second or third application is needed, and at what interval. do not skip follow-up appointments, and do not add extra doses without explicit vet guidance.

what owners often get wrong

using the cat or dog formulation without vet guidance. Revolution products for cats and dogs contain selamectin at concentrations designed for those species. a standard feline application contains significantly more active ingredient than what is appropriate for a small rabbit. applying it directly, without weight-based calculation from a vet, can cause toxicity and in serious cases death. the cost of a vet visit is not worth skipping for this reason.

treating without confirming the diagnosis. ear debris, scratching, and flaky skin do not automatically mean mites. bacterial infections, yeast overgrowth, and simple wax build-up can look identical to an early mite infestation. applying selamectin when the real problem is bacterial means your rabbit gets no benefit and continues to suffer while the underlying condition worsens unchecked.

skipping follow-up doses. selamectin kills live parasites but does not destroy eggs. mite eggs hatch in cycles, typically over two to three weeks. your vet will prescribe a second or third application at specific intervals. skipping those doses allows the next generation of mites to establish before they are eliminated, and you end up back where you started.

neglecting the environment. treating your rabbit while leaving contaminated bedding, hay, and enclosure surfaces in place guarantees reinfection. after starting treatment, remove all existing bedding, discard remaining hay, and thoroughly clean your rabbit’s enclosure. wash any fabric items at high temperature. environmental hygiene is not optional.
