What are some problems that can occur when H. pylori is not treated?

When H. pylori goes untreated it may lead to ulcers or to worsening symptoms if you already have an ulcer.2 Common symptoms of peptic ulcer disease include the following:

  • dull ache or burning pain between the breastbone and the belly button (ulcer pain often occurs when the stomach is empty, between meals, and in the early morning hours, but it can occur at any time)1
  • pain that lasts from a few minutes to a few hours (use of an antacid may help the pain but does nothing to treat the infection)1
  • bloating, nausea or vomiting after eating1,2
  • bleeding may also occur, which may cause anemia if it persists1



  • Rarely some components of PYLERA® can affect the nervous system. Symptoms may include numbness or tingling of arms and legs, headache, blurred vision, and convulsive seizures.
    Tell your doctor immediately if you experience any of these symptoms.
  • An exaggerated sunburn reaction has been seen in some individuals taking tetracycline. Avoid exposure to sun or tanning beds while taking PYLERA®.
