My daughter is pregnant, which was confirmed on 11th may, 2019. She had consulted a gynaecologist and has been advised to take the following medicines: 1) c. Susten - 200 mg - 1-0-1, 2) pantocid -40 mg 1-0-1, 3) folic acid 5 mg - 1-0-0 & 4) inj. Proluton 500 mg - 4 (once a week). She has taken the medicines from 25th to 6th june, 2019 with great difficulty due to morning sickness and other connected symptoms. When she stopped susten - 200 mg, she finds much relieved and is taking normal food etc, otherwise with the medicine she was not able to get our her bed. When the doctor was again consulted on 8th june, she prescribed naturogest-200 mg instead of susten - 200 mg and the doze of injection proluton depot was reduced to 250 ml. She has not tried naturogest 250 mg fearing it would upset her again. Now, please advise if the intake of susten 200 mg or naturogest 200 mg is absolute must for a pregnant lady who is in her first trimester?
