A persistent dry cough lasting several months can have various causes, especially if it keeps returning despite treatment. Common possibilities include ongoing acid reflux (GERD), which can irritate the throat, chronic bronchitis, asthma, or postnasal drip from allergies or sinus issues.

Since you mentioned Pantodac (a proton pump inhibitor used for acid reflux), your cough might be related to reflux that is not fully controlled or another underlying cause. It’s important to revisit a pulmonologist (lung specialist) or a gastroenterologist to reassess your condition. They may recommend further tests like chest X-rays, lung function tests, or an endoscopy to check for reflux or other causes.

What you can do next:

• Keep a symptom diary noting when the cough worsens or improves.
• Avoid known reflux triggers such as spicy foods, caffeine, and lying down soon after eating.
• Follow up with a specialist for a thorough evaluation and possible adjustment of your treatment.
• If you develop new symptoms like difficulty breathing, coughing up blood, or severe chest pain, seek emergency care immediately.

Consulting a pulmonologist or gastroenterologist will help identify the exact cause and guide effective treatment.
