Uncovering the Root Causes of Medication Non Adherence: What are the Causes of Medication Non Adherence?

Taking medication as prescribed seems like a no-brainer, right? However, a startling number of patients are non-adherent to their meds. In fact, the World Health Organization (WHO) estimates that 50% of medications are not taken correctly. This widespread issue has led to adverse consequences for both the individual patient and the healthcare system. But what causes people to be medication non-adherent in the first place?

One common cause is forgetfulness – simply forgetting to take your medication on time can lead to missed doses and suboptimal benefits. Another issue is the complexity of medication regimens – some medications must be taken multiple times per day, while others must be coordinated with meals. This can be especially challenging for elderly or low-income patients who may have difficulties managing a medication schedule. Cost is another well-known barrier to medication adherence; even if patients understand the importance of their medication, affording it can be a struggle.

Understanding the underlying causes of medication non-adherence is critical for healthcare providers seeking to optimize patient outcomes. By addressing these root causes and providing appropriate support, patients can receive the full benefits of their medical treatments, saving money and improving quality of life.

Effects of Medication Non-Adherence

Non-adherence to medication is a growing concern in today’s world. It refers to a patient’s failure to take their prescribed medication as directed, including skipping doses, taking less than the prescribed dosage, or stopping medication altogether before the treatment course is completed. Medication non-adherence can be due to various reasons, both intentional and unintentional, such as cost, forgetfulness, side effects, and fear of addiction. Regardless of the reason behind it, medication non-adherence can lead to negative consequences on a patient’s health and well-being, including:

  • Reduced effectiveness of medication in controlling symptoms and preventing disease progression.
  • Increase in the risk of hospitalization, emergency room visits, and long-term care facility admission.
  • Increased healthcare costs over time due to the need for additional treatment or prolonged hospital stays.
  • Development of drug-resistant bacteria and other microorganisms which can lead to the spread of infectious diseases.
  • Reduced quality of life due to the persistence of symptoms that could have been eradicated by regular medication use.

By not adhering to medication, patients may be undermining their own health and well-being, and this can have far-reaching outcomes and may lead to ill-health consequences.

Importance of Medication Adherence

Medication adherence refers to following the prescribed dosage, frequency, and duration of medication treatment. It may seem like a simple task, yet many patients struggle with medication nonadherence. In fact, medication nonadherence is a complex healthcare problem that has significant consequences for patients and society at large. Here are some key reasons why medication adherence is crucial:

  • Improved Health Outcomes: In many cases, medication adherence can mean the difference between good and poor health outcomes. Adherence to medication regimens has been shown to improve symptoms, reduce disease progression, and prevent complications associated with chronic conditions like hypertension, diabetes, and heart disease.
  • Reduced Healthcare Costs: Poor medication adherence is a major contributor to unnecessary healthcare utilization and costs. Patients who fail to follow their medication regimens are more likely to experience disease complications and hospitalization, resulting in increased medical costs. Adherence to medication regimens has been shown to decrease healthcare costs associated with chronic conditions.
  • Increased Quality of Life: Chronic conditions can negatively impact a patient’s quality of life, affecting their ability to function and engage in daily activities. Adherence to medication regimens has been shown to improve patients’ perceptions of their quality of life, enhancing their ability to perform daily tasks and engage in social activities.

Medication side effects and non-adherence

Medications can be lifesaving, but they can also come with a host of side effects. For many patients, dealing with side effects can be a major obstacle to taking their medications as prescribed. In fact, studies have shown that side effects can be a major cause of medication non-adherence.

Some common side effects of medications include:

  • Nausea and vomiting
  • Dizziness or lightheadedness
  • Headaches
  • Drowsiness or fatigue
  • Changes in appetite
  • Constipation or diarrhea

For patients who experience these side effects, the decision to stop taking their medication may seem like the best option. Unfortunately, discontinuing medication can have serious consequences, especially for those with chronic conditions.

It’s important for healthcare providers to discuss potential side effects with their patients and work together to find solutions to manage them. This may include adjusting the dosage of the medication, adding a new medication to counteract side effects, or recommending lifestyle changes such as exercise or diet modifications.

The importance of communication

Effective communication is key when it comes to managing medication side effects. Patients should feel comfortable discussing any concerns they have with their healthcare provider, and healthcare providers should take the time to listen to their patients and provide clear explanations of potential side effects and available options.

Patients may also benefit from keeping a journal to track any changes or side effects they experience while taking their medication. This can help healthcare providers better understand the patient’s unique needs and make adjustments as needed.


Medication side effects can be a major barrier to adherence, but with effective communication and a willingness to work together, patients and healthcare providers can find solutions that work for everyone. It’s important for patients to feel heard and supported, and for healthcare providers to take a holistic approach to medication management that addresses both the benefits and potential risks of medication.

Non-adherence among elderly population

Medication non-adherence is a significant challenge among the elderly population. Non-adherence leads to poorer health outcomes, higher medical costs, and increased risk of hospitalization. Below are some of the reasons why non-adherence is prevalent among the elderly.

  • Complex medication regimen: Elderly individuals often have multiple chronic conditions that require medications. These conditions can lead to complex medication regimens that are difficult to follow. It is challenging for elderly individuals to remember when to take each medication, how much to take, and whether it should be taken with food or not.
  • Physical limitations: The elderly population may have physical limitations that make it challenging to manage their medications. For example, arthritis may make it difficult to open prescription bottles, and poor eyesight may make it difficult to read medication labels.
  • Cognitive impairment: Dementia and other cognitive impairments can make it challenging for elderly individuals to remember to take their medications or understand their medication regimens.

The table below provides a summary of some of the other reasons why medication non-adherence is prevalent among the elderly population:

Reasons for Medication Non-Adherence Among Elderly
Difficulty with medication management
Financial constraints
Side effects from medication
Forgotten a dose
Lack of awareness about medications

It is crucial to address medication non-adherence among the elderly to improve health outcomes, reduce medical costs, and prevent hospitalizations. Healthcare providers should work with elderly individuals to simplify their medication regimens, provide suitable tools to manage their medications, and educate them about their medications.

Non-adherence due to forgetfulness

One of the most common reasons for medication non-adherence is forgetfulness. A lot of patients who have been prescribed medication tend to forget to take their doses at the correct time, or they may forget to take them altogether.

There are several factors that can contribute to forgetfulness, including:

  • Busy lifestyle
  • Complex medication regimen
  • Cognitive impairment
  • Poor health literacy

Patients who lead busy lives may find it difficult to remember to take their medication as instructed. They may have several things on their minds, and their medication regimen can easily slip their mind. Similarly, patients with complex medication regimens may be overwhelmed and find it difficult to keep track of all their medications and when they should be taken.

Cognitive impairment is another factor that contributes to forgetfulness. Patients with conditions such as dementia or Alzheimer’s disease may find it difficult to remember their medications. Poor health literacy can also contribute to forgetfulness, as patients may not fully understand their medication regimen or its importance.

To address non-adherence due to forgetfulness, healthcare providers can employ several strategies. These include:

Strategy Description
Reminder systems Patient reminders such as phone calls, emails, text messages, or automated medication dispensers can help patients remember their medication schedule.
Simplified medication regimen Reducing the complexity of a medication regimen can help patients remember their medications and increase adherence.
Medication synchronization Aligning all of the patient’s medication refills to the same day can help simplify their medication regimen and make it easier to remember.
Education and counseling Providing patients with education and counseling on the importance of taking their medication as prescribed can help improve adherence.

By employing these strategies and addressing forgetfulness, healthcare providers can help improve medication adherence, which can lead to better health outcomes for patients.

Relationship between mental health and medication non-adherence

Medication non-adherence is a common problem among people with mental health conditions. In fact, it is estimated that roughly 50% of people with mental illnesses do not take their medication as prescribed. The following are some reasons why mental health patients may struggle to adhere to their medication regimen:

  • Lack of insight: Some individuals with mental health conditions may not fully understand the benefits of medication or the consequences of not taking it. This lack of insight can make it difficult for them to prioritize their medication regimen.
  • Side effects: Many mental health medications have side effects that can be uncomfortable or even debilitating. Patients may choose to discontinue their medication because they find the side effects intolerable.
  • Stigma: There is often a social stigma attached to taking medication for mental health conditions. Some individuals may feel ashamed or embarrassed about their medication regimen and choose to stop taking their medication as a result.

In addition to these reasons, there is also evidence to suggest that certain mental health conditions may be more strongly associated with medication non-adherence than others. For example, individuals with schizophrenia and bipolar disorder have been found to be more likely to discontinue their medication than those with depression.

Mental Health Condition Non-Adherence Rate
Schizophrenia 60-70%
Bipolar Disorder 40-60%
Depression 30-50%

Overall, it is clear that mental health plays a significant role in medication non-adherence. Patients with mental health conditions may require extra support to help them understand the importance of their medication regimen and overcome any barriers they may face.

Tips for Improving Medication Adherence

Medication non-adherence can be a difficult issue to tackle, but there are ways to improve medication adherence. Here are seven tips for improving medication adherence:

  • Provide Education: Physicians must inform patients about their condition, the importance of medication, potential side effects, and expected outcomes. This education can help patients understand the need for their medication and adhere to treatment plans.
  • Create Reminders: Medication reminders are critical for people who have a hard time remembering to take their medication. Smartphone apps, email reminders, clocks, pillboxes, or family members can be used as reminders.
  • Simplify Medication Regimes: A complicated medication regime may overwhelm patients and make them give up. Patients should be consulted and encouraged to take their pills at times that are convenient to their daily lives.
  • Empower Personal Responsibility: Patients must learn that their medication allows them to take care of themselves properly, and they have an essential role to play in their treatment. Patients must be encouraged to take action to make their health better.
  • Monitor Progress: Physicians or pharmacists can track the patient’s progress, remind them of the need for medication, and address any adverse effects. Blood tests, physical checkups, and medication monitoring can help track progress.
  • Eliminate Barriers: Poor literacy, inadequate health literacy, socioeconomic status, cultural barriers, and difficulty in accessing medical care can hinder medication adherence. Physicians must communicate clearly and work to overcome these barriers.
  • Engage in Shared Decision Making: Shared decision-making is a collaborative process between doctors and patients in which both parties work together to determine the best treatment plan. This strategy allows patients to be involved in their treatment and make choices that reflect their preferences and values.

Tracking Medication Adherence

One effective tool for improving medication adherence is tracking. The Medication Possession Ratio (MPR) is a useful way to measure whether a patient is refilling their prescriptions regularly. It is calculated by dividing the total number of days a patient has medication by the total number of days between the first and last prescription refill. Research has suggested that a patient with an MPR greater than 80% is considered adherent, whereas a patient with an MPR of less than 80% is considered non-adherent.

MPR Adherence Level
≥ 80% Adherent
< 80% Non-adherent

Tracking medication adherence can help health care professionals intervene where necessary to ensure patients optimally adhere to their medication regimens.
