Microgest 200 mg (micronized progesterone) can be administered either orally (swallowed with water) or vaginally (inserted deep into the vagina). At 23 weeks of pregnancy, the vaginal route is very commonly preferred because it targets the uterus and cervix directly while minimizing systemic side effects like drowsiness and dizziness. However, the correct route depends entirely on your doctor's specific recommendation for your pregnancy. Please consult your obstetrician to confirm whether you should swallow the tablet or insert it vaginally, and always follow their precise instructions.
