[Subcutaneous administration in geriatrics : current evidence and recommendations]

Several medications used in geriatrics are approved exclusively for intravenous administration. However, some of these agents may also be administered subcutaneously in specific clinical situations, particularly in patients with difficult venous access or when maintaining intravenous access is inappropriate. Frequently used in geriatrics and palliative care, the subcutaneous route represents a simple, minimally invasive, and generally well-tolerated alternative. In the absence of formal marketing authorization for this route of administration, its use remains the responsibility of the prescribing physician, who should rely on the available scientific evidence, assess the benefit-risk ratio for each patient, and ensure appropriate clinical monitoring.
