Glucosamine Chondroitin Sulfate
Glucosamine Chondroitin Sulfate is used in veterinary medicine for adjunctive management of degenerative joint disease.
Group
Joint nutritional supplement
Mechanism of Action
Provides precursors associated with cartilage glycosaminoglycan synthesis; clinical response is inconsistent.
Dose Rates
Horse
| Use / stage | Dose | Route | Schedule | Instructions |
|---|---|---|---|---|
| Joint supplement loading | Reference only | PO | Glucosamine 12 mg/kg plus chondroitin sulfate 3.8 mg/kg twice daily for 4 weeks; then glucosamine 4 mg/kg plus chondroitin 1.3 mg/kg, with maintenance frequency not explicitly restated. | |
| Alternative joint supplement loading | Reference only | PO | Glucosamine 22 mg/kg plus chondroitin sulfate 8.8 mg/kg daily. Component-specific combination protocol. |
Dog
| Use / stage | Dose | Route | Schedule | Instructions |
|---|---|---|---|---|
| Glucosamine supplementation | 22 mg/kg | PO | Every 24 h | Glucosamine component only, not combined glucosamine/chondroitin mass. |
| Glucosamine supplementation | 44 mg/kg | PO | Every 24 h | Higher initial or escalation amount; glucosamine component only. |
| Chondroitin-component supplementation | Reference only | PO | 13–15 mg/kg of the chondroitin component every 24–48 hours. This is not the glucosamine dose or the combined mass; a single parent active ingredient cannot select both component bases safely. | |
| Cancer-pain supplement adjunct | Reference only | PO | 15–30 mg/kg of the chondroitin component daily for 4–6 weeks, then halve the amount. A combination supplement is used; the amount is not total product mass. |
Cat
| Use / stage | Dose | Route | Schedule | Instructions |
|---|---|---|---|---|
| Glucosamine supplementation | 22 mg/kg | PO | Every 24 h | Glucosamine component only, not combined glucosamine/chondroitin mass. |
| Glucosamine supplementation | 44 mg/kg | PO | Every 24 h | Higher initial or escalation amount; glucosamine component only. |
| Chondroitin-component supplementation | Reference only | PO | 15–20 mg/kg of the chondroitin component every 24–48 hours. This is not the glucosamine dose or the combined mass; a single parent active ingredient cannot select both component bases safely. | |
| Cancer-pain supplement adjunct | Reference only | PO | 15–30 mg/kg of the chondroitin component daily for 4–6 weeks, then halve the amount. A combination supplement is used; the amount is not total product mass. |

Contraindications

Interactions
- Can be used with NSAIDs.
Adverse effects
- Soft stools, gas and possible hypersensitivity
Monitoring and Administration
Assess mobility and comfort rather than assuming disease modification. Product purity, component amounts and salt forms vary.
General source glucosamine amounts are 22 mg/kg/day, increased to 44 mg/kg/day if needed; these are glucosamine-component amounts and do not define a complete combination-product regimen.
Historical capsule counts: 1–2 daily for dogs, 2–4 for large dogs, and 1 daily for cats, but exact product variants and dog-size boundaries are not fully defined.
The historical Cosequin description includes unspecified mixed glycosaminoglycans and ambiguously related manganese amounts; a complete active-ingredient list cannot be encoded reliably from it.
