I'm sorry to hear that your dry cough has been persistent and troubling despite multiple consultations. A chronic dry cough lasting several months can have various causes, including but not limited to:

• Gastroesophageal reflux disease (GERD): Acid reflux can irritate the throat and cause a chronic cough. Medications like Rabeprazole (a proton pump inhibitor) combined with Domperidone (a prokinetic agent) are sometimes used to manage this condition.
• Postnasal drip or sinus issues
• Asthma or other respiratory conditions
• Chronic bronchitis or other lung diseases
• Medication side effects

Given that your cough has persisted despite previous medical advice, here are some steps you might consider:

• Revisit a specialist: A pulmonologist (lung specialist) or an ENT (ear, nose, and throat) doctor can perform detailed evaluations including imaging, lung function tests, or endoscopy if needed.
• Review current medications: If you are on treatments like Rabeprazole-Domperidone capsules for acid reflux, ensure adherence and discuss with your doctor if symptoms persist or worsen.
• Lifestyle modifications: Avoid irritants such as smoking, allergens, and acid reflux triggers (spicy foods, caffeine, acidic foods).
• Further investigations: Sometimes, persistent cough requires chest X-rays, CT scans, or allergy testing to identify underlying causes.

Because persistent cough can sometimes signal serious conditions, it is important to follow up with a specialist doctor promptly for a thorough assessment and tailored treatment plan.

If your symptoms worsen suddenly or you experience difficulty breathing, chest pain, or coughing up blood, seek emergency medical care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
