My wife is currently more than 4 months pregnant but has a cough. So doctor, can pregnant women use cough syrup? If so, which type of cough syrup should pregnant women use? Thank you for your advice and answers!

Coughing is a common symptom during pregnancy, which can be related to respiratory diseases or just a symptom of irritation in the throat area. So, does coughing in pregnant women affect the development of the fetus?
