Which of the following medications require a shared care form?

The requirement for a shared care form typically pertains to medications prescribed for specific conditions that necessitate collaboration between general practitioners and specialists. In this case, Donepezil, Memantine, and Galantamine are all used to treat Alzheimer's disease, which often involves multiple healthcare providers in managing the patient's treatment plan.

These medications, particularly when prescribed for dementia-related conditions, often necessitate careful monitoring and adjustments, making the involvement of both the primary care physician and specialists essential. Quetiapine, while primarily an antipsychotic, may also be used in certain contexts of shared management, particularly in patients with complex psychiatric needs.

The involvement of a shared care protocol helps ensure safety, efficacy, and continuity of care, especially given the potential side effects and the need for regular assessment in managing chronic conditions like Alzheimer's disease. Thus, the correct answer reflects medications that are closely tied to a collaborative care approach due to their complexity and the need for ongoing assessment.
