Medication adherence is one of the most important factors that determines the therapeutic outcomes, especailly patient suffering from chronic illness/diseases.
The causes of nonadherence can be managed to reduce the risk of the patient not taking their medication.
Here are some of the causes of non-adherence:
Forgetfulness - Just like implementing any new habit, incorporating the act of taking medication into your daily routine can be a challenge at the start. It requires reminders, accountability, and drive to stay consistent. Even for veteran mediators, a change in environment or schedule can throw off their routine and lead to missed doses.
Fear & Worry - As a patient, it’s common to have anxiety around new medication, perhaps around expected side effects or the social stigma of taking medication in public. This may result in a patient intentionally not taking their medication and then fearing to tell the truth to their healthcare provider. By educating the patient on their condition, their upcoming journey, how to cope with side effects, and the importance of their medication, they can be better supported to overcome any fears or challenges they may face.
Misunderstanding - What a medicine is prescribed for, how the medication should be taken (e.g., together with a meal or not), and for how long the medication should be taken is information that can often be misunderstood or misinterpreted between doctor and patient.
Adverse side effects - For many, the side effects of a new medication may be too negative or intense to wish to continue being adherent. Similar to fear and worry, a patient may intentionally stop taking their medication due to the side effects. It is important to report any adverse side effects and to discuss with a doctor how to manage side effects that will appear along the way, and when it is time to change medication if they become too severe.
Complex medication schedules - Complex medication schedules require supporting your medication organization in addition to having set reminders to take doses throughout the day at the right time intervals. For some patients, such as minors, others may have to be involved to support the patient in medicating.
Lack of symptoms - It has been shown that it is particularly difficult to maintain a medication-taking behaviour when the medicine is of a preventive nature. If a medication is taken to avoid an event in the future, and when the patient does not feel any direct positive effect from taking the medication or direct negative effect from not taking the medication, it is, of course, even harder to keep the motivation high.
Thank you for this comprehensive overview. You’ve clearly highlighted the multifactorial nature of medication non-adherence and the importance of patient education, communication, and simplified treatment plans in improving therapeutic outcomes
Well explained; addressing forgetfulness, fear, side effects, and education through patient counseling and follow-up is key to improving long-term medication adherence.
Non-adherence of medication schedule can cause more harm than good. The article gives a good overview about the causes of non-adherence in patients which will help us to create easier dosage schedule and counsel the patient for better treatment outcomes.
Yes I too have noticed this lack of understanding among some patients. When the patients come for review careful analysis has to be made on medical adherence also.
Patient counselling about the medication, its effects, timing, and proper use should be clearly explained, even if briefly. However, limited time in our healthcare system often restricts this, leading to reduced drug effectiveness.
