If you’ve been prescribed Biaxin, you probably have questions about why your doctor chose it and what you need to do. Biaxin is the brand name for clarithromycin, a macrolide antibiotic that fights bacteria in the throat, lungs, skin and other parts of the body.
Unlike some antibiotics that you take only once a day, Biaxin usually comes in a tablet taken twice daily. The exact schedule depends on the infection, your age and kidney function. Always follow the doctor’s directions – missing doses can let bacteria survive and cause a relapse.
Biaxin is often prescribed for:
If you have a chronic lung condition such as COPD, your doctor might use Biaxin to treat flare‑ups caused by bacterial infection. It’s also an option when you’re allergic to penicillin.
Take the tablet with a full glass of water. You can eat before or after, but avoid grapefruit juice because it can raise drug levels and increase side effects. If you feel nauseous, try taking it with food.
Finish the entire prescription even if you start feeling better after a few days. Stopping early lets bacteria grow back and may make them harder to treat later.
If you miss a dose, take it as soon as you remember unless it’s almost time for your next one. In that case, skip the missed dose – don’t double up.
The most frequent complaints are stomach upset, mild diarrhea and a taste change in the mouth. These usually go away after a few days. If you get severe diarrhea, especially if it’s watery or contains blood, call your doctor right away – it could be C. difficile infection.
Other possible effects include headache, dizziness or an itchy rash. A rash that spreads quickly or causes swelling needs immediate medical attention.
Biaxin can interact with several medicines, such as statins (cholesterol drugs), blood thinners like warfarin, and some heart rhythm medications. Tell your pharmacist about every prescription, over‑the‑counter drug and supplement you use.
If you have liver disease, kidney problems or a history of abnormal heart rhythms, let the doctor know before starting Biaxin. Those conditions may require a lower dose or a different antibiotic.
On our site you can also read about Ceftin (cefuroxime) – another common antibiotic that works differently. While Ceftin is a cephalosporin, Biaxin belongs to the macrolide class, which means it covers some bacteria that Ceftin doesn’t.
Choosing between them depends on the infection type, allergy history and how your body handles each drug. Our detailed guides help you understand those differences.If you’re curious about buying Biaxin safely online, remember to use a licensed pharmacy that requires a prescription.
