Pro Helps the body repair its own tissues
Adequan (or polysulfated glycosaminoglycan) injections provide "building blocks" similar to glycosaminoglycans already present in the cartilage, so the body absorbs them well and uses to suppress inflammation and stimulate the synthesis of replacement cartilage.
Pro Few side effects
The biggest (but still rare) side effect is an increased risk of bleeding.
The initial treatment requires six injections over three weeks, and later maintenance injections every three to six weeks, depending on the dog. One 500 mg/5 ml vial costs about $70, and one injection for a dog of a larger breed can require about 140-160 mg.
