A single 1g dose of azithromycin generally causes mild side effects. However, some individuals experience more pronounced reactions. Common side effects include nausea, diarrhea, vomiting, and abdominal pain. Less frequent but potentially serious side effects include allergic reactions (rash, itching, swelling, difficulty breathing), irregular heartbeat, and liver problems.
Always inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements. Azithromycin interacts with several medications, potentially altering their effectiveness or increasing the risk of side effects.
| Anticoagulants | Warfarin | Increased bleeding risk |
| Ergot alkaloids | Ergotamine, Dihydroergotamine | Increased risk of ergotism (peripheral vasoconstriction) |
| Pimozide | Pimozide | Increased risk of QT prolongation (heart rhythm disturbance) |
| Statins | Simvastatin | Increased risk of myopathy (muscle damage) |
| Digoxin | Digoxin | Increased Digoxin levels |
If you experience any unusual symptoms after taking azithromycin, contact your doctor immediately. This information is not a substitute for professional medical advice.
