For a short-term cough of 4 days, you can try over-the-counter cough syrups depending on the type of cough. For a dry, irritating cough, a soothing syrup like a simple demulcent cough syrup may help. For a wet cough with mucus, an expectorant syrup can help loosen phlegm. In addition, drink warm fluids, honey with water, and do steam inhalation to ease throat irritation.

At 4 months of pregnancy, most common coughs are due to mild infections or allergies, but it is important to choose medicines carefully. Start with safe home remedies like warm fluids, honey with warm water (if no diabetes), steam inhalation, and saline nasal sprays, which can help soothe the throat and reduce cough. If medicine is needed, doctors may prescribe pregnancy-safe options such as simple cough syrups or antihistamines, depending on your symptoms, but avoid taking any over-the-counter medicines on your own. Always check with your doctor before starting any medication to ensure it is safe for you and your baby. Seek medical advice if the cough is severe, lasts more than a few days, or is associated with fever, breathlessness, or chest pain.

A cough that changes with the weather, sometimes wet and sometimes dry, is often due to cold, viral infection, or allergies. To relieve it, you can try steam inhalation, warm fluids, honey with water, and avoiding dust or cold air. For wet cough, medicines that help loosen mucus (expectorants) may be useful, while for dry cough, soothing cough syrups can help reduce irritation.
