Anxiety disorders are among the most prevalent psychiatric conditions worldwide; however, a significant proportion of affected individuals do not receive adequate treatment because of barriers such as stigma, limited access to specialists, and geographical constraints. Recent advances in digital medicine have introduced new possibilities to address these challenges. This review summarizes the current clinical applications of digital interventions for anxiety disorders across diagnosis, treatment, and relapse prevention stages. Particular attention has been paid to internet-based cognitive behavioral therapy (ICBT), which has presented efficacy comparable to face-to-face CBT for conditions such as panic disorder, social anxiety disorder, and generalized anxiety disorder. However, its use has several limitations, including reduced effectiveness in obsessive-compulsive disorders and issues related to digital literacy. Furthermore, ethical and legal implications, such as those related to privacy protection, liability, and health equity, must be addressed to ensure safe and equitable implementation. Emerging technologies, including virtual reality and AI-based personalization, provide promising directions for future development. Furthermore, digital medicine holds substantial potential as a complementary tool for the treatment of anxiety disorders, but its widespread adoption requires ongoing empirical validation and the development of appropriate regulatory and clinical frameworks.
