Maintenance therapy refers to ongoing treatment that is given to a patient after their initial treatment for a chronic or long-term condition has been completed. This type of therapy is often used to prevent a relapse or recurrence of the condition and to help manage symptoms or improve the patient's quality of life over the long term. Maintenance therapy can involve a variety of interventions, such as medications, physical therapy, counseling, or lifestyle changes, and is typically personalized to the individual patient's needs and goals. Maintenance therapy is commonly used in the treatment of conditions such as cancer, asthma, diabetes, mental health disorders, and autoimmune diseases.
