Multiple Sclerosis (MS) is a chronic, progressive central nervous system disease that cannot be cured in the light of current information. Disability, weakness, tremors, balance and movement problems, fatigue and depression are observed in the vast majority of MS patients. Compared with other chronic disease states, MS patients feel more uncertainty and less control over illness and non-illness aspects of life, and as a result, they have poor self-management abilities. Self-management can be defined as an individual's ability to manage symptoms, treatment, physical and psychological consequences of illness, and making lifestyle changes specific to living with a chronic condition. In studies, it was thought that providing evidence-based information and using balanced information in terms of risk/benefit in patient education would affect the patient's participation in the shared decision-making process. Self-management programs for MS patients are insufficient and this is a factor in the failure of self-management to be fully adopted. It was revealed that self-efficacy, perception of treatment control, and realistic MS process knowledge were associated with self-management in MS patients. It is thought that a developed comprehensive self-management module will contribute to the literature and clinical practice, and will positively affect the treatment process of patients. Clinical pharmacy is defined by the American College of Clinical Pharmacy as a health science offered by the pharmacist in order to organize the patient's drug therapy in the most appropriate way and to protect health, ensure healing and prevent disease. Accordingly, the clinical pharmacist is responsible for identifying and preventing the patient's possible problems with drug therapy (such as drug dose/dosing frequency/administration route suitability, drug interactions, side effects, compliance, education and information needs, therapeutic drug monitoring requirement), and other healthcare professionals. It takes part in cooperation with the multidisciplinary team, provides necessary information about drugs and ensures the continuation of rational drug treatment. Studies have reported that as a result of the integration of the clinical pharmacist into the MS outpatient clinic, patients' access to drugs is facilitated, care coordination and patient outcomes are improved. In addition, it has been shown that the presence of a clinical pharmacist in a multidisciplinary team contributes to increasing compliance, making drug follow-ups of patients, and improving communication with physicians. As a result of all these, the self-confidence of the patient, who played a key role in the joint decision-making model, increased and it was observed that the patients were more willing to be involved in the joint decision-making process.

The aim of this study is to improve the self-management of MS patients by informing them about the disease, treatment options, and appropriate drug use by the clinical pharmacist, and to analyze the effect of the self-management module in the short term (4 months) and long term (8 months) by examining the change in patients' self-management, participation in the treatment process and care satisfaction and compliance.
