What is Avelox?
Avelox (moxifloxacin) is a fluoroquinolone antibiotic used to treat infections caused by bacteria.
It treats conditions such as pneumonia, an infection of the lungs, and skin infections, which are caused by bacteria entering the skin.
It is also used for intra-abdominal infections, which affect organs inside the abdomen, and sinusitis, an infection of the sinuses (the air spaces in the skull around the nose).
Some common uses of Avelox include treating the plague, a severe bacterial infection caused by Yersinia pestis, and acute bacterial exacerbations of chronic bronchitis, a flare-up of an ongoing lung condition that causes coughing and difficulty breathing.
Avelox is also used for certain skin infections, which are simpler to treat and usually involve only the outer layers of the skin. However, to avoid making bacteria resistant to the drug, it is important to use Avelox only for bacterial infections that are susceptible to this antibiotic.
Always talk to a doctor to ensure Avelox is the right choice for your infection.
How Does Avelox Work?
Avelox works by stopping the growth of harmful bacteria that cause infections. It is part of a group of antibiotics called fluoroquinolones, which are designed to fight bacterial infections.
Avelox targets an essential part of bacteria called enzymes, specifically DNA gyrase and topoisomerase IV.
These enzymes help bacteria copy and repair their DNA. When Avelox blocks these enzymes, the bacteria cannot multiply or survive, which helps clear the infection.
This makes Avelox effective in treating respiratory, skin, sinus, and intra-abdominal infections.
Always use Avelox as prescribed to ensure the best results and avoid antibiotic resistance.
Dosage Information and Usage
Avelox medication is available in oral and intravenous forms, offering flexibility in treatment depending on the patient’s needs.
Dosage Form and Strengths of Avelox
Avelox comes in two primary forms with consistent strength to make dosing simple and effective:
- Avelox Tablets: 400 mg moxifloxacin hydrochloride, oblong, dull red, film-coated, imprinted with “BAYER” on one side and “M400” on the other.
- Avelox Injection: 400 mg moxifloxacin hydrochloride in 250 mL of 0.8% sodium chloride aqueous solution, ready-to-use in flexibags.
How to Use Avelox?
Take Avelox exactly as your doctor prescribed. The recommended adult dose is 400 mg once daily, given orally or as a 60-minute intravenous infusion. Duration depends on the infection: typically 5–10 days for respiratory infections and up to 14 days for complicated intra-abdominal infections.
You can take Avelox tablets with or without food, but drink plenty of fluids.
Avoid taking Avelox with products that contain magnesium, aluminum, iron, or zinc (such as antacids or multivitamins) within 4 hours before or 8 hours after taking the medication. These can reduce the effectiveness of Avelox antibiotics.
Healthcare professionals will administer Avelox injections through a slow intravenous infusion over 60 minutes.
To ensure the infection is fully treated, always complete the entire course of Avelox medication, even if you start to feel better.
Storage Information
Store Avelox medication properly to ensure its effectiveness. Keep Avelox tablets at 25°C (77°F), but short-term exposure between 15°C and 30°C (59°F and 86°F) is allowed.
Store them in a dry place away from high humidity.
Keep Avelox antibiotics in premix bags at room temperature and use them without dilution.
Always check the packaging for damage and avoid exposing the medication to extreme temperatures or moisture.
Proper Avelox storage helps maintain its quality and ensures safe use.

Warnings and Precautions
- Severe and Irreversible Side Effects: Avelox can cause disabling and sometimes permanent side effects. These include tendinitis, tendon rupture, peripheral neuropathy (nerve damage), and central nervous system (CNS) effects like hallucinations, anxiety, and confusion. Stop Avelox immediately if any of these symptoms occur.
- Tendinitis and Tendon Rupture: Avelox may increase the risk of tendon inflammation or rupture, especially in people over 60, those taking corticosteroids, or patients with kidney, heart, or lung transplants. The Achilles tendon is most commonly affected. Stop taking Avelox and consult your doctor if you experience pain, swelling, or other tendon issues.
- Peripheral Neuropathy: Avelox can damage nerves, leading to pain, burning, tingling, numbness, or weakness. These symptoms can appear quickly and may be permanent. If you notice any of these signs, discontinue Avelox immediately.
- Central Nervous System Effects: Avelox may cause CNS side effects like seizures, anxiety, depression, hallucinations, confusion, or suicidal thoughts. These reactions can happen even after the first dose. Stop Avelox and seek medical help if any of these symptoms occur.
- Exacerbation of Myasthenia Gravis: Avelox can worsen muscle weakness in people with myasthenia gravis, leading to severe breathing issues. Avoid Avelox if you have a history of myasthenia gravis.
- QT Prolongation: Avelox can cause changes in heart rhythm (QT prolongation), which may lead to serious heart problems. Avoid Avelox if you have a history of heart rhythm issues, low potassium or magnesium, or are taking medications that prolong the QT interval.
- Severe Allergic Reactions: Avelox may trigger severe allergic reactions, including anaphylaxis, which can be life-threatening. Symptoms may include rash, itching, swelling, breathing difficulties, or dizziness. Discontinue Avelox and seek emergency medical help if you experience these signs.
- Liver and Kidney Problems: Avelox can cause liver damage, including hepatitis or liver failure, and may also affect kidney function. Signs include jaundice (yellowing of the skin or eyes), dark urine, or severe abdominal pain. Stop taking Avelox and contact your doctor immediately if you notice these symptoms.
- Blood Disorders: Avelox may lead to blood-related issues, such as anemia, low white blood cell count, or clotting problems. Symptoms include unusual bruising, bleeding, or persistent fatigue.
- Hypersensitivity Reactions: Some people may experience severe skin reactions, such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Stop taking Avelox if you develop skin rashes, blisters, or peeling.
