OCD usually takes about 2 weeks of medication to have a significant effect, and 4-8 weeks of medication to stabilize the disease. After stabilization, consolidation and maintenance treatment is needed, especially for about six months. This is because OCD is a disease that is very prone to relapse, especially because OCD has character flaws, such as being strong and perfectionist. Without consolidation treatment, relapses can easily occur. If you have had one relapse, you will need to consolidate for a longer period of time, and you will need to consolidate for more than one year after your condition has stabilized. If there are 2 or more relapses, the consolidation period will be extended, even for more than 2 years. If there are more relapses, long-term medication or even lifelong medication should be considered. Therefore, in either case, it is important to consider the relapse of OCD, the effect of medication, and the resistance to medication after the use of medication. However, usually the first OCD patient takes medication for at least 6 months.
