A heavy, dry cough with throat pain is commonly caused by a viral infection (cold or flu), throat inflammation (pharyngitis or laryngitis), or irritation from dust, smoke, or allergies. It may also occur due to post-nasal drip or acid reflux affecting the throat. You can relieve it by drinking warm fluids, gargling with salt water, resting your voice, and using honey or paracetamol for pain relief. If needed, over-the-counter lozenges or cough suppressants may help reduce coughing. Please see a doctor if your cough lasts more than two weeks or if you develop chest pain or shortness of breath.

A cough can be dry or wet, and the treatment depends on its type. For a dry (non-productive) cough, a suppressant syrup containing dextromethorphan may help, while for a wet (productive) cough, an expectorant such as guaifenesin can help loosen mucus. Warm fluids, honey, and rest may also provide relief. It is best to consult a doctor to determine the cause of your cough and receive appropriate treatment.

A cough can feel worse at night because lying flat allows mucus from the nose and sinuses to drip into the throat, which can cause irritation. Stomach acid can also travel upward more easily when lying down, triggering coughing. Some conditions, such as asthma, can worsen at night as the airways become more sensitive. Dry or cold air may also irritate the airways and increase coughing at night. If the cough lasts more than a few weeks or becomes severe, you should seek medical advice.

For a dry cough while breastfeeding, cough syrups containing dextromethorphan are generally considered safe when used at normal doses. Avoid syrups with codeine or strong sedating antihistamines, as they may affect the baby or milk supply. You can also use simple supportive measures, such as warm fluids and honey, if suitable for you. If the cough persists or worsens, it is best to consult a doctor for personalised advice.

Your symptoms are most commonly caused by a viral infection such as the common cold or flu. These infections can cause cough, sore throat, body pains, tiredness and sometimes a mild fever as your immune system responds to the virus. In most cases, it improves within a few days with rest, fluids, and simple pain-relief medicines, if needed. If your symptoms become severe, persist for more than a week, or you develop a high fever or breathing difficulty, please seek medical advice.

You may use Cosome A Syrup (Ambroxol, Guaifenesin and Terbutaline) if your cough is chesty with mucus or is associated with wheezing, as it helps loosen mucus and open the airways. It is not suitable for a dry cough and should be used with caution if you have heart disease, high blood pressure, or thyroid problems. Since your cough has lasted for a week, it is important to consult a doctor to identify possible causes, such as infection or allergy, and receive appropriate treatment.
