Medication During Pregnancy

<!-- translated-chunk:28/53 -->

Q: My period started on April 28 and ended on May 3. On May 12, I underwent a whole-body CT scan excluding the head. On May 21, I was prescribed medication for urinary stones: one tablet each of promethazine hydrochloride, atropine sulfate, and levofloxacin hydrochloride, which I took twice in total. Starting on the 31st, I began taking famciclovir dispersible tablets (one tablet per day), cefaclor dispersible tablets (two tablets per day), and prednisone acetate tablets (one tablet per day) until June 4. During this time, I also took 18 tablets of medroxyprogesterone acetate. This morning, I discovered that I am pregnant. Is it safe to continue the pregnancy? Can anything be done to remedy the situation?

A: Within the first month of pregnancy, the impact is generally minimal. The human body has a complete placental barrier, which prevents most drugs from reaching the fetus. Taking medication for only a few days should not cause major problems; however, prolonged use may pose risks. There's no need to worry.
