These medications contain a proton pump inhibitor (pantoprazole or rabeprazole) and domperidone. While helpful, using them long-term can sometimes affect bone strength, vitamin B12 absorption, and kidney health. Since you are 24, it is highly recommended to consult a gastroenterologist to find the root cause of your stomach issues, possibly through an endoscopy. Please do not stop these medications suddenly, as this can cause a rebound of acid symptoms. Your doctor can help you safely taper down while finding a safer, long-term management plan.

Please be reassured that these medications are highly unlikely to have harmed your baby. Zintac (ranitidine) and the pantoprazole in Pantocid DSR are generally considered safe during pregnancy. However, the domperidone component of Pantocid DSR and Heppacid syrup are best avoided or used only under strict medical advice. I gently recommend discussing your severe symptoms with your obstetrician. They can safely evaluate your upper stomach pain and tailor a pregnancy-safe treatment plan to bring you comfort.

This rebound effect is common when stopping such medications suddenly. However, your new difficulty in swallowing is an important symptom that needs attention. I highly recommend consulting a gastroenterologist soon. They can safely evaluate your swallowing, possibly with a simple endoscopy, and help you gradually taper off your medication to avoid rebound acidity. Please be reassured that this is manageable, but a professional evaluation is the safest next step to ensure you heal comfortably.

Your ongoing sore throat, loss of voice, and nighttime ear pain suggest that acid might still be reaching your throat and vocal cords when you lie down. This is common and often called silent reflux. To help, try elevating the head of your bed by six inches and avoid eating within three hours of sleeping. Please consult an Ear, Nose, and Throat (ENT) specialist to evaluate your throat and safely adjust your medication.

Your throat irritation and the 'stuck' sensation could be linked to acid reflux irritating your throat, which explains why pantoprazole and domperidone (Pantocid DSR) provides temporary relief. It is also possible a lingering infection is present, as azithromycin (Aziwak 500) only helped briefly. I highly recommend visiting an ENT specialist. They can look closely at your throat to determine if you need a targeted reflux treatment or a different approach for the infection. In the meantime, try warm salt-water gargles, stay hydrated, and avoid lying down immediately after eating.

Pantocid DSR (pantoprazole with domperidone) is indeed safe and most effective when taken on an empty stomach, usually 30 minutes before breakfast, to relieve gas and nausea. However, Metrogyl 400 (metronidazole) is an antibiotic. It is not designed to treat general gas or headaches and should only be taken if a doctor has diagnosed a specific infection. Taking antibiotics unnecessarily might actually worsen your stomach upset or headache. Please consult a doctor to confirm if Metrogyl is necessary for you, and focus on sipping water to stay hydrated.
