What is moxifloxacin used for?

Moxifloxacin is a fluoroquinolone antibiotic used to treat bacterial infections such as community-acquired pneumonia, acute bacterial sinusitis, chronic bronchitis flare-ups, and certain skin and intra-abdominal infections. It only works against bacteria, not viruses.

Do I need a prescription for moxifloxacin?

Yes. Moxifloxacin is a prescription-only medication in the United States. A licensed provider must evaluate your condition and issue a valid prescription before the pharmacy can dispense it.

How do I take moxifloxacin 400mg?

The standard adult dose is one 400mg tablet by mouth once daily, with or without food, for the duration your provider prescribes. Take it at least 4 hours before or 8 hours after antacids, multivitamins, or products containing iron or zinc.

Is moxifloxacin the same as Avelox?

Yes. Avelox is the brand name for moxifloxacin. Generic moxifloxacin contains the same active ingredient and is held to the same FDA standards as the brand product.

What are the most important side effects to watch for?

Seek medical attention for tendon pain or swelling, irregular heartbeat, numbness or tingling, severe diarrhea, or signs of an allergic reaction. Fluoroquinolones carry a boxed warning for tendon rupture, nerve damage, and central nervous system effects.

How does ordering and shipping work?

After you place an order, a licensed provider or pharmacist reviews your prescription and health information. Once approved, your medication is dispensed and shipped from a licensed U.S. pharmacy, typically with tracking provided.

Can I drink alcohol or take antacids with moxifloxacin?

There is no direct interaction with moderate alcohol, but alcohol may worsen dizziness. Antacids and mineral supplements can block absorption, so separate them from your dose by at least 4 hours before or 8 hours after.

What Is Moxifloxacin 400mg?

Moxifloxacin is a fluoroquinolone antibiotic, sold under the brand name Avelox, used to treat a range of bacterial infections in adults. It works by blocking bacterial enzymes needed for DNA replication, which stops bacteria from multiplying. Moxifloxacin is taken as a 400mg tablet once daily and only treats bacterial infections — it does not work for viral illnesses like colds or the flu. Because fluoroquinolones carry certain serious risks, moxifloxacin is generally reserved for infections where other treatment options are not appropriate.
