Azithromycin, while generally well-tolerated, can cause side effects. Common ones include diarrhea, nausea, vomiting, and abdominal pain. Less frequent, but still possible, are allergic reactions (rash, itching, swelling), headache, dizziness, and changes in taste.
Gastrointestinal Issues
Gastrointestinal upset is the most prevalent side effect. Mild cases often resolve without intervention. However, severe diarrhea might indicate Clostridium difficile infection, requiring prompt medical attention. Consider probiotics to mitigate this risk.
Drug Interactions
Azithromycin interacts with several medications. This means its effects might be altered, or the other drug’s efficacy reduced. Examples include: drugs metabolized by the liver (like certain blood thinners or statins), ergot alkaloids (used to treat migraines), and some antacids. Always inform your doctor about all medications you take, including over-the-counter drugs and supplements.
Other Potential Side Effects
Though rare, serious side effects exist, including liver damage and irregular heart rhythms. Immediate medical help is necessary if you experience severe abdominal pain, jaundice (yellowing of skin or eyes), rapid or irregular heartbeat, or shortness of breath.
Important Considerations
This information is not exhaustive. Always consult a doctor or pharmacist before starting or stopping any medication. They can assess your individual health status and provide tailored advice.

Heart Rhythm Problems
Azithromycin can prolong the QT interval, potentially leading to abnormal heart rhythms. Individuals with pre-existing heart conditions should exercise extra caution and discuss this thoroughly with their physician before taking this antibiotic.
