Zithromax (azithromycin) can cause gastrointestinal upset in some individuals. The most common side effects are nausea, diarrhea, and abdominal pain. These typically are mild and resolve without treatment. However, severe diarrhea, particularly if bloody or accompanied by fever, requires immediate medical attention.
Consider these points:
| Nausea | Common | Take Zithromax with food or a light snack to minimize nausea. If nausea persists, contact your doctor. |
| Diarrhea | Common | Drink plenty of fluids to prevent dehydration. If diarrhea is severe or persistent, contact your doctor. Avoid anti-diarrheal medications without consulting your doctor, as they can worsen the condition. |
| Abdominal Pain | Less common | Mild pain usually subsides. Severe or persistent pain requires medical attention. |
| Vomiting | Less common | If vomiting occurs, contact your doctor, especially if you are unable to keep down fluids. |
While rare, more serious gastrointestinal complications such as pseudomembranous colitis (a severe form of diarrhea) can occur. Seek immediate medical attention if you experience severe, persistent diarrhea with fever or blood in your stool. Your doctor can assess the situation and provide appropriate treatment.
Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, before starting Zithromax to avoid potential interactions.
