Finally got over my med fear and started lexapro (escitalopram) after 20 yrs of ocd. just realized they expired 2 mos ago. safe to continue through the weekend?

Yup: You'll be fine. Go get some new pills Monday.

Congratulations: It's great to hear that you've been able to battle and win over your condition of OCD after such a long road. You're almost there. Now's NOT the time to panic. You can wait a bit more until you get medication which is still within the time of viability. You should never use any medication or prescription that is expired (typically 1 year from the time of being filled or written).
