Your symptoms suggest a common cold or environmental allergies. For the sneezing, an over-the-counter antihistamine like cetirizine or loratadine can provide relief. For the cough, a cough suppressant like dextromethorphan is helpful if it is dry, while an expectorant like guaifenesin can help if you are coughing up mucus. Staying well-hydrated and using saline nasal sprays will also help soothe your airways. These symptoms are very common and typically improve with rest. However, if you experience shortness of breath, high fever, or if symptoms do not improve after a week, please consult a doctor for a physical examination.

Your morning sneezing is likely due to allergic rhinitis, commonly triggered by indoor allergens like dust mites. For relief, you can try a daily, non-drowsy oral antihistamine such as Cetirizine, Loratadine, or Fexofenadine. Alternatively, a steroid nasal spray like Fluticasone is highly effective at reducing nasal inflammation when used consistently. To help manage symptoms, try keeping your bedroom dust-free and washing bedding weekly in hot water. While these over-the-counter options are generally safe and effective, please consult a healthcare provider to confirm the diagnosis and get a personalised treatment plan.
