I had one dose of fansidar (3 pills oral )while i was pregnant in the 5th week...what should i do?does it effecting my baby?

It's used in preg-: Nancy when risk of malaria is > risk of fansidar, usually given >16 wks. Since it lowers Folic Acid levels & <36 wks. Since it can cause severe newborn jaundice & not while breastfeeding. Studies of pregnant rats given high doses showed fetal risk, but no controlled studies exist in humans. Serial fetal ultrasounds can show anatomy & growth. Even if you're past 10 wks., take folate (folic acid) supplements.
