Why Patients Stop Taking Prescribed Medication (and What Pharma Can Actually Do About It)

Half to three-quarters of patients don’t take their medications as prescribed. This leads to thousands of preventable deaths, worsened chronic conditions, and $300 billion in avoidable healthcare costs annually. For pharmaceutical companies, it also means lost revenue and weaker data on drug effectiveness. But why do patients stop taking their medications?

Here’s a quick breakdown of the main reasons:

• Cost: High out-of-pocket expenses lead to abandonment rates as high as 60% for medications costing over $500.
• Forgetfulness and Routine Issues: Busy schedules, polypharmacy (multiple medications), and lack of symptoms make adherence difficult.
• Side Effects or Physical Challenges: Fear of side effects and difficulties like swallowing pills or needle phobia deter patients.
• Poor Understanding and Support: Many patients don’t fully understand their treatment or feel unsupported by healthcare providers.

The good news? Addressing these issues works. Every $1 spent on improving adherence saves $7 in healthcare costs. Solutions include simplifying medication regimens, offering financial aid, improving patient education, and using digital tools like mentorship platforms and adherence tracking.

When patients feel informed and supported, they’re more likely to stick to their treatment plans.

Why Patients Stop Taking Their Medication

Non-adherence to medication isn't a one-size-fits-all issue. Patients might intentionally stop taking their prescriptions due to reasons like cost, side effects, or the belief that they no longer need treatment. Others miss doses unintentionally because of forgetfulness, challenges with refills, or complicated dosing schedules.

Forgetting Doses and Broken Routines

Managing chronic conditions such as hypertension or diabetes often involves daily medication, which can feel overwhelming. When symptoms aren’t immediately noticeable, some patients may question the importance of sticking to their regimen.

"Being a patient, especially being a patient with a chronic condition, is a lot of work." - Victor Montori, MD, Professor of Medicine, Mayo Clinic

The situation becomes even more difficult for patients juggling multiple medications. Polypharmacy, or the need to take several drugs at different times, significantly complicates adherence. Studies show that as the number of daily doses increases, adherence rates drop. For older adults, especially those with cognitive challenges, this issue is even more pronounced, making them particularly vulnerable to missing doses.

Side Effects and Difficulty Taking Medication

Side effects are a leading reason patients stop taking their medication, even when those effects are short-lived. Fear of potential side effects often outweighs the benefits of treatment, despite evidence showing that 83% of side effects from diabetes medications resolve within one month.

Physical difficulties also play a surprising role. For instance, up to 40% of adults experience trouble swallowing at some point, and 69% of those individuals admit to skipping medication because of it. Needle phobia, impacting 20% to 30% of young adults, can deter patients from injectable treatments altogether. Poor communication between doctors and patients exacerbates these challenges. In fact, non-adherence rates are nearly 20% higher among patients whose physicians score low on communication skills.

Cost and Financial Strain

The cost of medication is a major reason patients abandon their prescriptions. When out-of-pocket expenses rise above $500, abandonment rates soar to around 60%. This is especially true for specialty medications, such as cancer treatments, where oral oncolytics see abandonment rates as high as 67%.

Each January, abandonment rates spike as insurance deductibles reset, forcing patients to cover higher out-of-pocket costs. Shockingly, about $30 billion in manufacturer copay assistance goes unused every year.

Poor Understanding and Lack of Support

When patients don’t fully understand the purpose of their medication or what to expect from it, they’re far more likely to stop taking it. Up to 55% of medication non-adherence is linked to inadequate communication between patients and their physicians.

Patients who feel unsupported often make treatment decisions on their own, sometimes based on misinformation or distrust. For example, news stories about pharmaceutical marketing can create skepticism about a doctor’s motives for prescribing certain medications. Without a trusted source of guidance - whether it’s a healthcare provider, family member, or peer - patients are left to navigate complex treatment choices by themselves.

"It is the relationship between the doctor and patient that drives the compliance." - Helen Shields, MD, Professor, Harvard Medical School

These challenges highlight the need for solutions tailored to improving adherence, which will be explored in the next section.

Strategies That Help Patients Stay on Their Medication

Helping patients stick to their medication plans is just as important as understanding why they might stray from them. Thankfully, healthcare providers have several practical tools and methods they can use. These strategies set the stage for the digital solutions covered in the next section.

Simplifying Medication Regimens

One of the easiest ways to improve adherence is to simplify the medication routine. Options like once-daily dosing, fixed-dose combinations, or long-acting formulations can significantly reduce the daily hassle for patients. Aligning medications to be taken at the same time of day, offering mail-order delivery to remove the inconvenience of refills, or connecting medication use to daily habits - like keeping pills near the coffeemaker or setting phone alarms - can make the process feel more natural. These small adjustments create a solid base for addressing other challenges, such as financial or educational barriers.

Financial Assistance and Cost Relief Programs

Although cost relief programs are available, many patients don’t take advantage of them - often because they don’t know they exist. For instance, in 2025, AbbVie's myAbbVie Assist program provided free medications to over 210,000 individuals in the U.S. who qualified based on financial need and lacked adequate insurance. This program covered specialty drugs like Humira, Skyrizi, and Rinvoq, with no copays or shipping fees.

Patients with chronic conditions often express a desire for more information about financial support but remain unaware of how prescription-discount services operate. Health systems that implement consistent patient assistance advocacy across all clinics have a better chance of reaching patients before they give up on their prescriptions.

"Having a standardized patient assistance program strategy across the health system is the best way to address adherence and abandonment." - O'Mally Monahan, McKesson

Patient Education and Family Involvement

When patients don’t fully understand why they’re taking a medication - especially for conditions without noticeable symptoms - they’re more likely to stop. Clear, straightforward communication is key. For example, saying, "Let's try this for your high blood pressure", is more relatable than using medical jargon like "This will treat your hypertension".

Family involvement can also make a big difference. For older adults juggling multiple conditions, a family member who understands the treatment plan can provide reminders and help integrate doses into daily routines. When it comes to children, caregiver knowledge often determines whether medications are taken consistently. Shared decision-making - where patients and families are actively involved in treatment choices - fosters trust and a sense of ownership, which are critical for long-term adherence.

"Medication adherence is a behavior that needs to be understood, not a problem to be solved." - Dr. Hayden Bosworth, Professor of Medicine, Duke University

These patient-focused strategies work hand-in-hand with the digital tools explored in the following section.

How Pharma Can Use Digital Tools to Improve Adherence

The patient-focused strategies discussed earlier - like simplifying treatment plans, offering financial aid, and involving family - tackle adherence from a personal perspective. Digital tools take these efforts further by enabling pharma companies to reach a much larger audience in real time. Let's explore some of the key digital innovations helping to improve medication adherence.

Real-Time Patient Mentorship Platforms

One powerful way to address gaps in understanding and support is through peer mentorship. These platforms connect patients with experienced peers who can offer guidance and emotional support. For example, PatientPartner pairs patients with mentors who share their experiences, providing support at scale.

Research shows that mentorship’s impact on patient decision making can boost medication adherence by 29%. Patients with mentors also tend to stick to their prescribed therapies for an average of 133.5 days longer compared to those without mentorship. Additionally, mentorship leads to a 68% increase in new patient starts.

"Patient Partner has been influential in helping patients understand the benefits of our product, providing them with personalized guidance and real-life experiences to support their decision-making." - Brad A., Mainstay Medical

These platforms are designed with compliance in mind, adhering to HIPAA, SOC 2, and ISO 27001 standards. They are also easy to integrate into existing systems, typically within four months. By empowering patients to learn from peers, mentorship platforms reduce the educational burden on healthcare providers like pharmacists and nurses.

While mentorship offers real-time support, digital education programs address another critical gap: providing accurate, accessible information tailored to different patient needs.

Health Education Programs Built for Diverse Patients

Digital education programs aim to close knowledge gaps by delivering evidence-based, up-to-date content that evolves with clinical advancements. But reaching a diverse patient base means more than just translating materials - it requires delivering the right information in the right way, whether through SMS, mobile apps, or QR codes.

Christian Hartman, PharmD, MBA, Vice President of Product Innovation at Wolters Kluwer Health, highlights the importance of timing and format:

"The key to effective patient engagement is providing the right information to the right patient at the right time in the right format."

This is crucial because 80% of patients leave healthcare visits with unanswered questions. Digital education tools that align with clinician-approved content can fill these gaps without adding to the workload of healthcare teams.

Data Analytics and Adherence Tracking Tools

Advances in data analytics now allow pharma companies to predict and prevent medication non-adherence. Predictive tools use adherence risk scoring to identify patients who may be struggling and trigger timely interventions.

For instance, Merck KGaA partnered with Medisafe to create a customized digital medication program that improved adherence by up to 20% within five months. Additionally, real-world data from May 2023 revealed that 25% of patients were taking a leading asthma medication at the wrong time of day. This insight enabled targeted educational efforts to correct the issue before it compromised treatment outcomes.

Territory-level analytics provide even more value by helping brand teams identify regional challenges, such as cost or access issues, and adjust support programs accordingly. Features like caregiver integration, which notify family members about missed doses, further enhance adherence by creating a connected support network.

Digital tools like these are transforming how pharma tackles adherence, offering scalable, data-driven solutions that address patient needs from multiple angles.

Conclusion: Closing the Gap in Medication Adherence

Medication nonadherence arises from various challenges - forgetting doses, managing side effects, dealing with high costs, navigating complex instructions, and lacking consistent support. These obstacles lead to preventable deaths and soaring healthcare expenses, straining the entire system.

Acknowledging these barriers paves the way for meaningful solutions. Today, pharma companies have an array of options to tackle this issue. Simplifying regimens, providing financial aid, and involving family members can significantly impact individuals. On a larger scale, digital tools like PatientPartner's mentorship platforms, educational initiatives, and real-time data analytics offer powerful ways to address adherence issues as they happen.

At the heart of these strategies lies trust. When patients feel understood, informed, and supported, they are much more likely to stick to their treatment plans. And the payoff is undeniable - every $1 spent on improving adherence saves $7 in overall healthcare costs.

For pharma leaders, the solution isn’t about picking one strategy over another. It’s about combining human connection, digital innovation, and open communication to meet patients where they are. This blend creates a unified approach that helps patients stay on track with their therapy.
