my sister is 36 yrs old, she is pregnant (4 -5 weeks). This is her second pregnancy. She is having high BP. Her doctor has prescribed her few medicines: Pubergen HP injections ( once in a week), Loprin 75, Valium 5 and Arg 9. I want to know is it safe to have these medicines during pregnancy ?
Yes these are safe in pregnancy.  But she needs regular checkup and if her BP is high then antihypertensive is required.  Regular BLD tests and USG is required.
