Choose the right antibiotic based on your specific infection and medical history. Consult your doctor for personalized advice.
Dosage
Zithromax (azithromycin) dosages vary greatly depending on the infection being treated. Common regimens include a single 1-gram dose or a 500mg dose on day one followed by 250mg daily for four days. Biaxin (clarithromycin) is typically prescribed at 250-500mg twice daily for 7-14 days. Always follow your doctor’s prescribed dosage precisely.
Side Effects
Both medications can cause nausea, diarrhea, vomiting, and abdominal pain. Zithromax may also cause a slightly higher risk of prolonged QT interval, a heart rhythm abnormality. Biaxin, additionally, may interact with certain medications affecting the liver. Report any unusual symptoms to your healthcare provider immediately. This is not an exhaustive list.
Drug Interactions
Zithromax interacts with drugs metabolized by the liver’s cytochrome P450 system, potentially altering their effectiveness or increasing the risk of side effects. Biaxin similarly interacts with many medications, notably statins and certain anticoagulants. Always provide your doctor with a complete list of your current medications and supplements to avoid harmful interactions. Your physician can best assess potential conflicts.
