Azithromycin (Zithromax) is commonly prescribed, but it’s not always the best fit. If you can’t take it, if it failed, or if resistance is a concern, there are other options. This guide lists common alternatives, what they treat best, and simple safety notes to help your conversation with a clinician.
Doxycycline: A tetracycline often used for respiratory infections, acne, tick-borne diseases, and some STIs. It works well for community-acquired pneumonia and sinusitis when atypical bacteria are suspected. Doxycycline is usually taken twice daily; avoid in pregnancy and children under 8 due to tooth and bone effects.
Amoxicillin (± clavulanate): A penicillin group antibiotic that covers many ear, throat, and sinus infections. It’s a first choice for many acute bacterial sinusitis cases and otitis media. If resistance or beta-lactamase producing bacteria are suspected, amoxicillin-clavulanate is preferred.
Clarithromycin and erythromycin: Macrolides like clarithromycin can substitute for azithromycin in respiratory infections and H. pylori regimens. Clarithromycin has more drug interactions than azithromycin, so check with your pharmacist or doctor if you take other meds.
Cefuroxime and cefdinir: These cephalosporins work well for skin infections, ear infections, and some sinus or bronchial infections. They’re a reasonable choice if penicillin allergy is not severe. For severe penicillin allergy, avoid cephalosporins unless cleared by a provider.
Trimethoprim-sulfamethoxazole (TMP-SMX): Often used for skin infections like MRSA and urinary tract infections. It’s not a go-to for some respiratory infections, but it’s useful where MRSA is suspected.
Fluoroquinolones (levofloxacin, moxifloxacin): Broad spectrum drugs used for complicated pneumonia, some urinary infections, and certain resistant cases. They carry higher risk for tendon, nerve, and other side effects, so doctors reserve them for specific situations.
Match the drug to the bug and the site of infection. For example, doxycycline or amoxicillin for typical community respiratory infections; TMP-SMX for suspected MRSA skin infections; fluoroquinolones for certain severe or resistant cases. If the infection is sexually transmitted, azithromycin alternatives for chlamydia include doxycycline which is often preferred for uncomplicated cases.
Always tell your provider about allergies, pregnancy, breastfeeding, and other medicines you take. Drug interactions and pregnancy status change which antibiotic is safest. When possible, a throat or wound culture and a sensitivity test guide the best choice.
Quick dosing and side-effect notes: typical adult doses are doxycycline 100 mg twice daily, amoxicillin 500 mg three times daily (or 875/125 mg twice daily for amoxicillin-clavulanate), TMP-SMX one double-strength tablet twice daily, and levofloxacin 500 mg once daily for certain infections. Common side effects include stomach upset, diarrhea, yeast infections, and sun sensitivity with doxycycline. Stop and call your doctor for rash, severe diarrhea, breathing trouble, or tendon pain immediately.
If you’re unsure, ask for a short explanation: why this antibiotic, how long to take it, common side effects, and when to call back. Don’t stop early unless instructed—finishing the course helps prevent resistance. If symptoms worsen or new symptoms appear, contact your healthcare provider right away.
