Function

• Zithromax is used to treat bacterial infections. It is a macrolide antibiotic that works by either killing the bacteria or preventing further bacterial growth.
  
  

Effects

• Zithromax commonly causes stomach distress, including diarrhea. Diarrhea medications should not be used as a remedy, because they may worsen the condition. Stomach pain and cramps may also occur, and sometimes abdominal pain may be severe.
  
  

Stomach Pain Medications

• Over-the-counter antacids may help alleviate some of the pain. These medications may include choices such as Maalox or stronger remedies such as Tagament or Pepcid AC.
  
  

Other Treatments

• Taking a warm bath and resting may help to cope with abdominal pain.
  
  

Prevention/Solution

• If pain is not alleviated with over-the-counter treatments, contact your physician. The doctor may recommend that you discontinue use of Zithromax in favor of another antibiotic.
