Sugar gliders (Petaurus breviceps) turn up in exotic practice far more often than the reference literature would suggest, and they are among the most frequently mis-managed small exotics on the table. The single most useful thing to fix at the outset is a category error: a sugar glider is a marsupial, not a rodent and not a small primate. Most general drug handbooks either omit them entirely or lump them under "pocket pets" alongside hamsters and rats — animals with fundamentally different metabolism, dentition, diet, and clearance. This guide collects the dosing patterns we see most often for gliders across the exotic-companion-mammal literature, with the actual numbers, citations, and evidence levels held on the individual drug pages rather than in prose.

Browse the full sugar-glider formulary for the live, source-cited dose data, and use the calculator to run weight-based math on any of the rules below.

Why sugar glider dosing is not "rodent dosing"

Four physiological realities should anchor every glider prescribing decision. None is exotic in isolation, but together they explain why extrapolating a rat or hamster protocol is unsafe.

• Very small body mass, high metabolic rate. Adult gliders weigh roughly 100–160 g, joeys far less. High surface-area-to-volume ratio means rapid heat loss under anaesthesia and a metabolic rate that can drive faster clearance of some drugs. Accurate dosing at this scale demands a gram-resolution scale and, almost always, dilution of stock concentrations — the margin between a therapeutic and a toxic volume is a fraction of a millilitre.
• Marsupial metabolism and torpor. Gliders are heterothermic and can enter torpor when cold, stressed, or energy-depleted. A torpid or hypothermic glider does not metabolise, distribute, or clear drugs predictably; stabilise temperature and energy status before you rely on any calculated dose. Marsupial hepatic and renal handling of drugs is incompletely characterised, so clinical response should temper published extrapolations.
• A gum- and nectar-feeding gut. Gliders are omnivorous exudivores — sap, gum, nectar, pollen, and invertebrates in the wild. Their gastrointestinal tract, transit time, and microbiome are adapted to that niche, not to a granivore's. Oral antibiotic effects on gut flora and the palatability of a compounded suspension both matter more than in a rodent.
• Husbandry-driven, not primarily infectious, disease. The bread-and-butter glider caseload is metabolic and behavioural: nutritional secondary hyperparathyroidism (NSHP) and metabolic bone disease, self-mutilation and other stress-related behavioural disease, hind-limb paresis, dental disease, and obesity. The drug you reach for is frequently supportive, not a targeted anti-infective.

Antibiotic and antifungal dosing notes

Bacterial infection in gliders is real but over-diagnosed relative to nutritional and behavioural disease; confirm with cytology, culture, and sensitivity where you can rather than reaching reflexively for a broad-spectrum drug.

• Trimethoprim-Sulfamethoxazole — a common oral first-line for gliders where a broad-spectrum potentiated sulphonamide is appropriate, typically on a q12h interval. Palatable compounded suspensions improve compliance.
• Enrofloxacin and Marbofloxacin — fluoroquinolones used for gram-negative coverage. Injectable enrofloxacin is irritating and can cause tissue necrosis at concentration; dilute and rotate sites, and prefer the oral route for courses. Ciprofloxacin is an oral alternative in the same class.
• Amoxicillin and Amoxicillin-clavulanic acid — beta-lactams used where a gram-positive or mixed infection (including some abscesses and dental-associated disease) is documented.
• Clindamycin — favoured for anaerobic and oral/dental infections given the frequency of dental disease in this species.
• Metronidazole — for anaerobic and protozoal disease; palatability is poor, so compounding matters. Chloramphenicol remains in the toolbox for specific indications where its tissue penetration is needed, with the usual human-exposure handling precautions.
• Itraconazole — the go-to azole for dermatophytosis and systemic fungal disease when antifungal therapy is indicated.

Check the species-specific entry on each drug page for the source-cited dose, interval, and evidence level before prescribing.

Antiparasitic dosing notes

Endoparasites and ectoparasites are less dominant than nutritional disease in captive-bred gliders but still appear, particularly in animals from high-density or poorly managed sources.

• Fenbendazole — the benzimidazole of choice for gastrointestinal nematodes, dosed as a multi-day course rather than a single treatment.
• Selamectin and Imidacloprid — topical options for mites and fleas; spot-on dosing at glider body mass requires careful volume measurement, not a "small mammal" pipette applied whole.
• Ivermectin — used for various ecto- and endoparasites; dilution is essential at this body size, and the usual macrocyclic-lactone caution applies.
• Praziquantel — for cestodes and trematodes where indicated by faecal findings.
• Piperazine — an older oral ascaricide that still appears in some protocols.

Analgesia and anaesthesia

Gliders mask pain and stress readily; a quiet, hunched, or over-grooming glider may be painful. Multimodal analgesia and meticulous thermal support are the two things most often done poorly.

• Buprenorphine — a partial mu-agonist widely used for moderate pain in exotic companion mammals and a reasonable default opioid for gliders.
• Butorphanol — a kappa-agonist used for sedation and mild analgesia, often combined with a benzodiazepine for procedural work.
• Meloxicam — the NSAID most commonly reached for; ensure the patient is well hydrated and normotensive before and during use, and reassess renal status on longer courses.
• Gabapentin and Tramadol — adjuncts for chronic, neuropathic, or self-mutilation-associated pain, used as part of a multimodal plan rather than as sole agents.
• Midazolam (reversible with Flumazenil) and Ketamine — components of injectable sedation and induction protocols; Glycopyrrolate or Atropine may be used as anticholinergic premedication. Atipamezole reverses alpha-2 agonists where those are part of the protocol.
• Bupivacaine — local/regional block to reduce systemic requirements during minor surgery, dental extractions, or wound management.

Inhalant anaesthesia via mask or chamber induction is standard, but the overriding peri-anaesthetic priority in a 120 g patient is preventing hypothermia and hypoglycaemia: warm surfaces, warmed fluids, minimal clip-and-prep time, and glucose support for stressed or anorexic animals.

Supportive care

For most glider presentations, supportive care is the therapy — not an afterthought to it.

• Calcium Gluconate — central to the management of hypocalcaemic crisis, tetany, and the hind-limb paresis of NSHP/metabolic bone disease. Injectable calcium is reserved for acute crisis; longer-term correction is dietary, with the diet itself being the definitive treatment.
• Metoclopramide and Cisapride — prokinetics for gastrointestinal stasis; Maropitant for nausea and as an antiemetic adjunct.
• Lactulose and Sucralfate — for hepatic support and gastrointestinal mucosal protection/ulcer management respectively.
• Prednisolone — used judiciously for specific inflammatory or immune-mediated indications, weighing its effects against infection and metabolic disease.
• Furosemide, Pimobendan, and Enalapril — cardiac support drugs for the occasional glider with congestive heart failure. Doxapram is a respiratory stimulant for neonatal or anaesthetic respiratory depression.

Common dosing mistakes

1. Treating the glider as a rodent. Diet, dentition, gut physiology, and marsupial metabolism all differ. Do not port a hamster or rat protocol wholesale; use glider- or exotic-companion-mammal-specific data from the drug pages.
2. Weighing and diluting carelessly. At 100–160 g, a rounding error or an undiluted stock concentration is a genuine overdose risk. Weigh in grams, dose in mg/kg, and dilute so the calculated volume is measurable. The ExoticRx calculator handles unit and concentration math.
3. Dosing a cold or torpid patient. A hypothermic or torpid glider will not clear drugs predictably. Stabilise temperature, hydration, and energy status first.
4. Chasing an infection that is really nutrition. Hind-limb weakness, pathological fractures, and seizures are far more often NSHP than sepsis. Radiograph, assess the diet, and correct calcium/phosphorus balance — antibiotics do not fix metabolic bone disease.
5. Under-managing self-mutilation as purely behavioural. Stress-related self-trauma frequently has a pain and husbandry component; address analgesia, environment, and any underlying disease alongside behavioural management. See related conditions references for a fuller work-up.
