Hi, My wife is 7-8 weeks pregnant and is very skinny (weighs approx 35 kilos). She has nausea and has been vomiting. She is unable to eat any solid or liquid food and is constantly vomiting every intake. After a visit at doctor she was prescribed folic acid as vitamin pills and emeset-4 mg (Ondansetron) for vomiting. Is it safe to take the emeset tablet. Will it have any immediate or after effects on the fetus? Thankyou.
