Contact your doctor immediately if you experience severe allergic reactions like difficulty breathing, swelling of your face, lips, tongue, or throat, or hives. Seek medical attention if you develop persistent or worsening diarrhea, which could indicate Clostridium difficile infection.
Other Reasons to Call Your Doctor
Report any unusual symptoms, even if seemingly mild. This includes persistent nausea, vomiting, or stomach pain. Also contact your doctor if you experience hearing loss, dizziness, or changes in your heart rhythm. Don’t hesitate to discuss any concerns about the medication with your physician; open communication is key to successful treatment.
If your symptoms don’t improve within a few days of starting Azithromycin, or if they worsen, contact your doctor. This is especially important for children, as their response to medication can differ.
