Glucosamine sulfate is an oral supplement used in the management and treatment of osteoarthritis. This activity outlines the indications, hypothesized action, and contraindications for glucosamine sulfate as a valuable agent in managing osteoarthritis. This activity will highlight the hypothesized mechanism of action, adverse event profile, suggested dosing, monitoring for relevant interactions, and other key elements of glucosamine sulfate supplementation in the clinical setting pertinent for members of an interprofessional team managing the care of patients with osteoarthritis. Objectives: Review the treatment considerations for osteoarthritic patients requesting to add glucosamine sulfate supplements to their treatment strategy. Describe the management considerations for patients taking glucosamine sulfate supplements. Summarize the risks associated with initiating glucosamine sulfate supplementation and related key patient counseling points. Explain the importance of collaboration and communication amongst the interprofessional team to ensure the appropriate screening of patients requesting glucosamine sulfate supplements as a part of their osteoarthritis management to improve patient outcomes by identifying contraindications and thus decreasing adverse events.

Through various studies, Glucosamine sulfate has consistently been concluded to be a relatively safe oral supplement. A few isolated case studies have reported on the incidence of hepatotoxicity following >3 weeks of glucosamine sulfate use. However, all patients cited had severe preexisting liver disease, with one of the eight patients mentioned developing hepatic failure.[17]

The evidence available on the effectiveness of glucosamine sulfate as a beneficial therapy in the management of osteoarthritis is, to date, inconclusive. Interestingly, studies have shown that patients are not deterred from supplement use when presented with data concluding lack of efficacy, with the only evidence of significant toxicity showing to be capable of causing changes in supplement consumption. Physicians should be mindful of this when discussing the benefits and risks of various treatment modalities with OA patients, particularly those of no validated benefit. The physician must personalize the risk and benefits of taking glucosamine sulfate to each patient. Typically, a 60-day trial of glucosamine sulfate will determine if there are beneficial effects, after which it should be discontinued if the patient has not observed any beneficial effect by that time. As patients search online for alternatives to medication, clinicians must stay educated on various supplements a patient may seek out for their condition. Communication between all interprofessional healthcare team members, including pharmacists, is crucial in these situations. A pharmacist will know how different drugs and supplements could interact with a patient's current medications. Through collaborative effort and open communication between clinicians, nurses, and pharmacists, patients can integrate glucosamine supplements into their OA treatment regimen more safely and avoid adverse effects.
