At 8 months of pregnancy, medicines should be used with caution, especially cough syrups containing bronchodilators like terbutaline, so avoid Bro-Zedex syrup unless your doctor specifically prescribes it. A wet cough for a few days may be due to a viral infection, and measures like warm fluids, steam inhalation, and rest can help relieve symptoms. As your cough persists despite current treatment, it is best to follow up with your doctor to reassess the cause and adjust medicines safely. Seek prompt care if you develop fever, breathing difficulty, or reduced foetal movements.
