Intradermal Needle Therapy for Major Depressive Disorder

A total of 120 participants with MDD who meet the inclusion criteria will be included in the study. Participants will be randomly divided into the SSRIs + acupuncture group, acupuncture + placebo group, and SSRIs + sham acupuncture group. This study will evaluate the efficacy and safety of the intradermal needle for MDD and investigate whether the intradermal needle reduces side effects and increases the efficacy of selective serotonin reuptake inhibitors (SSRIs) antidepressants for MDD. Furthermore, the study will demonstrate whether the intradermal needle has a synergistic effect with SSRIs on the treatment of MDD.
