[/INST] Hi,It is considered to be safe during pregnancy. Sysron-N is a synthetic form of female sex hormone progesterone commonly prescribed to support and maintain an early pregnancy which not only prevents miscarriage but also prevents preterm delivery in women. It is safe and hence your doctor has prescribed it.Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Mohammed Taher Ali, General & Family Physician </s>
