Polypharmacy - Risks and Supporting Safer Medication Management

Polypharmacy generally refers to the use of multiple medicines by one person. The term is often associated with individuals taking five or more medications, although there is no single universally applied definition.

Polypharmacy is particularly common among people living with multiple long-term conditions, such as diabetes, cardiovascular disease, chronic respiratory conditions, arthritis, and mental health conditions.

Importantly, polypharmacy is not always a concern, as many people benefit from taking several medicines where each prescription has a clear clinical purpose and contributes positively to their health and wellbeing.

Clinical guidance increasingly distinguishes between appropriate polypharmacy, where medicines are providing benefit, and problematic polypharmacy, where the risks or treatment burden may outweigh the benefits.

Understanding this distinction is an important part of effective medicines optimisation and person-centred care.

Several factors have contributed to the growth of polypharmacy across England, one of them being the ageing population. NHS England notes that a large proportion of older adults are living with two or more long-term conditions, increasing the need for ongoing medication management. As life expectancy has increased and treatments have advanced, more people are living longer with chronic health conditions that require long-term prescribing.

The growing prevalence of multimorbidity is another important factor. NICE identifies multimorbidity as the presence of multiple long-term conditions and highlights its association with increased treatment burden, including polypharmacy. Managing several conditions often means following multiple clinical guidelines, each recommending different medications.

Healthcare has also seen increasing use of preventative and risk-reduction medicines. Treatments aimed at preventing stroke, heart disease, osteoporosis, and other complications can increase the number of medicines an individual takes while helping to support better long-term outcomes.

While many people benefit from multiple medications, there are recognised risks associated with complex medication regimens.

Adverse Drug Reactions - As the number of prescribed medicines increases, so does the potential for side effects and adverse drug reactions. Older adults may be particularly vulnerable due to age-related changes in how medicines are absorbed and processed.

Drug Interactions - Certain medicines can interact with each other, affecting their effectiveness or increasing the likelihood of side effects. Interactions may also occur between prescribed medicines, over-the-counter products, and dietary supplements. NHS guidance highlights identifying potentially harmful combinations of medicines as an important component of medicines optimisation.

Falls and Frailty - Some medicines can contribute to dizziness, sedation, low blood pressure, or confusion. In older adults, these effects may increase the risk of falls, which can have a significant impact on health, independence, and quality of life. NHS polypharmacy monitoring tools specifically identify combinations of medicines associated with risks such as falls and confusion.

Reduced Adherence - Managing several medicines with different instructions can make adherence more challenging. Missed doses, incorrect administration, or confusion about treatment plans can affect outcomes and increase safety risks.

Increased Healthcare Utilisation - Problematic polypharmacy may contribute to avoidable healthcare interventions, including emergency care and hospital admissions linked to medication-related harm. This is one reason medicines optimisation remains a priority across the NHS.

Recognising Problematic Polypharmacy - Not all polypharmacy requires intervention, but there are indicators that may suggest a medication regimen would benefit from review.

These indicators can include:

• Multiple medicines with similar therapeutic purposes
• Prescriptions that appear to be treating side effects caused by other medicines
• Frequent changes to medication regimens
• Concerns about adherence or administration
• Increased reports of falls, confusion, or adverse effects
• Individuals taking large numbers of medicines without recent review

For care providers, early identification of these signs can help facilitate discussions with healthcare professionals and support timely medication reviews.

Consider an older adult living with several long-term conditions and taking eight regular medications. During a structured medication review involving their GP, pharmacist, family members, and care team, medicines are assessed against current needs, outcomes, and potential risks.

The review identifies opportunities to simplify the medication regimen and remove medicines that are no longer providing sufficient benefit. Care documentation is updated, monitoring arrangements are agreed, and digital medication records ensure all members of the care team have access to accurate information.

This type of coordinated approach reflects the principles of medicines optimisation, person-centred care, and integrated working promoted across health and social care guidance.

Medication reviews are a central part of medicines optimisation. NICE recommends structured reviews to assess whether medicines remain appropriate, effective, and aligned with an individual's needs and goals. Reviews can help identify opportunities to discontinue unnecessary medicines, simplify treatment plans, and reduce potential risks.

CQC also expects providers to engage with healthcare professionals to ensure medicines are reviewed at appropriate intervals.

The Care Act 2014 places individual wellbeing at the centre of care and support planning. This includes considering a person's preferences, priorities, independence, physical health, mental wellbeing, and desired outcomes when decisions are made about their care.

When managing polypharmacy, person-centred care means looking beyond the medication list to understand how treatment affects daily life and overall wellbeing.

Strengthen Multi-Disciplinary Working - Effective management of polypharmacy often depends on collaboration between GPs, pharmacists, nurses, carers, social care professionals, and families. NICE guidance highlights the importance of coordinated approaches to medicines optimisation and information sharing across care settings.

Focus on Medicines Optimisation - NHS England describes medicines optimisation as ensuring people receive the right medicines, at the right time, while remaining actively involved in decisions about their treatment. The aim is to improve outcomes, support safe use of medicines, reduce unnecessary prescribing, and minimise medicine-related harm.

As medication regimens become more complex, digital solutions can help care providers maintain oversight, improve record keeping, and support safer administration processes.

The CQC recognises the role of electronic medicines administration records (eMAR) in supporting medicines management within adult social care services. Digital systems can help improve the accuracy of medication records, support audit readiness, and strengthen communication between care teams.

Access Medication Management supports providers by digitising medication administration processes and reducing reliance on paper-based records. Through electronic medication administration records, care teams can record medication activity in real time, improve visibility of administration histories, and create auditable records that support compliance requirements.

The platform can help providers by:

• Supporting accurate medication recording
• Providing real-time visibility of medication administration
• Reducing the risk of missed or duplicate administration
• Supporting medication audits and reporting
• Improving communication between care teams
• Providing digital evidence to support safe medicines management processes

When used alongside regular medication reviews and clinical oversight, digital medication management can help providers strengthen governance arrangements while supporting safer, more coordinated care delivery. This aligns with wider expectations around medicines optimisation, good governance, and safe care.

While taking several medicines can be clinically appropriate and beneficial, complex medication regimens require careful oversight to minimise the risks associated with adverse reactions, drug interactions, falls, and treatment burden.

Regular medication reviews, person-centred care, strong collaboration between healthcare professionals, and a focus on medicines optimisation all play an important role in supporting safe outcomes. Digital solutions such as Access Medication Management can further strengthen medication governance by improving record keeping, visibility, and administration processes. Together, these approaches can help providers support safer medication management while keeping individual wellbeing at the centre of care.
