Hi,
Welcome to icliniq.com.
From your history, I understand that you are a thyroid patient and have had an IUI (intrauterine insemination) pregnancy. Hence, you would have been started on Aspirin ASA 50 (Acetylsalicylic Acid), Folic Acid and Progesterone support during your first trimester. Then, Iron syrup and Calcium in the second trimester. Now answering your questions one by one:-
1. Thyroxine has to be continued daily till birth and even post delivery for at least 6 weeks.
2. Aspirin (ASA 50 mg) has to be continued till 37 weeks or term or if you would go in labor earlier then it has to be stopped 48 hours prior.
3. Lrzin is actually L-arginine sachet which is started by 24-26 weeks daily especially in women whose blood pressure is on the higher range.
4. If the woman is gestation hypertensive then it will be prescribed with an aim to keep the blood pressure in check. It will also reduce the chance of pre-eclampsia in pregnancy. Pre-eclampsia, which affects approximately 1 in every 20 first time pregnancies, could be prevented if high risk pregnant women start taking a dietary supplement containing L-arginine and antioxidant vitamins during their 20th week of pregnancy. This has to be continued till 37th week again, if you are hypertensive and not required post pregnancy.
5. Injection Betamethasone (Betnesal) is to be administered ideally at 32 weeks of pregnancy in two doses of 12 mg each for 2 days, to allow fetal lung maturation. It will not prevent lungs in case the delivery is a pre-term which is often a risk in intrauterine insemination (IUI) pregnancies and also women who develop pre-eclampsia early in pregnancy and are not controlled by medication. The immediate aim is to take the pregnancy till at least 34 weeks when the fetal lungs naturally mature, but it is safer to give injection Betamethasone earlier. Injection Betamethasone do increase sugar level but momentarily for few days which can be controlled easily with diet restriction, if you are GDM (gestational diabetic) as well.
6. MCBM DHA is a folic acid plus DHA (Docosahexaenoic Acid) supplement which is to be continued till term and also for 3 months after delivery. DHA is a member of the omega-3 family of fatty acids. DHA plays an important role in brain and retinal development in infants. It is also the most abundant unsaturated fatty acid found in the brain. So, it is seen in studies that women who are supplemented with DHA during pregnancy give birth to children with higher IQs (intelligence quotient) which is evaluated at 2 years of age.
