How is duodenitis treated?

Treatment for duodenitis begins with seeking medical care from your health care provider. To determine if you have duodenitis, your health care provider may ask you to provide blood, urine, and stool samples for laboratory tests.

Antibiotic treatments for duodenal ulcer

If your duodenitis is caused by H pylori infection, antibiotic therapy is the mainstay of treatment. It is important to follow your antibiotic regimen precisely to avoid re-infection or recurrence. Most commonly, two antibiotics are given for 14 days. Examples of antibiotic treatments include:

  • Amoxicillin
  • Clarithromycin (Biaxin)
  • Metronidazole (Flagyl)
  • Tetracycline

Other medications to treat duodenitis

Medications such as proton pump inhibitors and histamine H2-receptor antagonists, which decrease the amount of acid in the stomach, can also be an effective treatment for duodenitis.

Proton pump inhibitors that may be effective in the treatment of duodenitis include:

  • Esomeprazole (Nexium)
  • Lansoprazole (Prevacid)
  • Omeprazole (Prilosec)
  • Pantoprazole (Protonix)
  • Rabeprazole (Aciphex)

Histamine H2-receptor antagonists that may be effective in the treatment of duodenitis include:

  • Cimetidine (Tagamet)
  • Famotidine (Pepcid)
  • Nizatidine (Axid)
  • Ranitidine (Zantac)

If you have diarrhea and vomiting, fluid and electrolyte replenishment is also a component of successful treatment.

What are the potential complications of duodenitis?

You can help minimize your risk of serious complications by following the treatment plan you and your health care professional design specifically for you. Complications of duodenitis include:

  • Abdominal wall inflammation
  • Internal hemorrhaging
  • Perforated peptic ulcer (bleeding stomach or intestinal ulcer)
