Taking cough syrup during pregnancy is generally not recommended, as it may not be more effective than other remedies such as drinking plenty of fluids or taking a teaspoon of honey. It is best to use nasal hygiene solutions like Hydrasense or Sinus Rinse to prevent mucus from dripping down the throat and causing coughing. Tylenol can be used for fever and pain, and throat lozenges like Halls or Fisherman's Friend can help with throat irritation. It is important to encourage the person to stay hydrated and seek medical advice if symptoms persist for more than 7 days without improvement.
