Azithromycin, while generally well-tolerated, can cause side effects. Common ones include nausea, diarrhea, and abdominal pain. These usually are mild and resolve without treatment.
Less common, but potentially serious, side effects include:
- Severe allergic reactions (rash, swelling, difficulty breathing) Heart rhythm problems (prolonged QT interval) Liver problems (jaundice, dark urine) Hearing loss
Seek immediate medical attention if you experience any of these serious side effects.
Azithromycin can interact with certain medications. These interactions can either reduce the effectiveness of azithromycin or increase the risk of side effects. Consult your doctor or pharmacist about potential interactions, especially if you are taking:
Anticoagulants (blood thinners): Azithromycin may increase the bleeding risk. Digoxin: Azithromycin can increase digoxin levels in the blood. Ergot alkaloids: A potentially dangerous interaction can occur. Drugs metabolized by the liver (CYP3A4 inhibitors and inducers): Azithromycin can affect their metabolism. Cisapride: Concurrent use may increase the risk of cardiac arrhythmias.
Always inform your doctor or pharmacist of all medications, supplements, and herbal remedies you are taking before starting azithromycin. This includes over-the-counter drugs. Accurate information ensures safer and more effective treatment.
