I'm sorry to hear that your dry cough is disturbing your sleep. A dry cough lasting a few days and worsening at night can be quite uncomfortable.

Since Betadine Gargle has not helped, you might consider a medication that targets cough symptoms more directly. For example, a syrup containing Chlorphenamine maleate and Dextromethorphan hydrobromide can help by reducing allergic reactions and suppressing the cough reflex. Such medications are typically prescribed by a doctor and can relieve cough due to throat irritation or allergies.

In addition to medication, here are some self-care tips you can try at home:

• Stay well hydrated with warm fluids like herbal teas or warm water with honey and lemon.
• Use a humidifier or inhale steam to soothe your throat.
• Avoid irritants such as smoke, strong perfumes, or dust.
• Elevate your head with an extra pillow while sleeping to reduce coughing at night.

If your cough persists beyond a week, worsens, or is accompanied by symptoms like fever, difficulty breathing, or chest pain, please consult a pulmonologist (lung specialist) promptly for a thorough evaluation.

For now, I recommend seeing a doctor to discuss appropriate cough syrup options and to rule out any underlying causes. If symptoms become severe or you experience breathing difficulty, seek emergency care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
