During pregnancy, it is best to avoid taking Cold Fx or any other medication that has not been studied in pregnant women. However, you can try using saline solutions like Hydrasense or Sinus Rinse to help with congestion, runny nose and cough. These can be used as often as needed throughout the day. Additionally, throat lozenges like Ricola or Fisherman's Friend can help with throat irritation and are safe to use during pregnancy. Fisherman's Friend is a good option because it does not contain sugar. Remember to consult with your healthcare provider before trying any new remedies during pregnancy.
