⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾
Levofloxacin carries the FDA's strongest warning. This antibiotic has been linked to serious, sometimes permanent side effects that can affect multiple parts of the body at the same time. These include:
- Tendinitis and tendon rupture — tendons (especially in the heel) can become inflamed or tear, sometimes months after finishing the medication
- Peripheral neuropathy — nerve damage causing tingling, numbness, pain, or weakness in the arms or legs, which may not go away
- Central nervous system effects — including hallucinations, severe anxiety, depression, confusion, and intense headaches
- Worsening of myasthenia gravis — a muscle-weakness condition that can become dangerously worse; people with this condition should not take levofloxacin
If you notice any of these problems, stop taking levofloxacin immediately and contact your doctor or go to the ER. For common infections like simple UTIs, sinus infections, or bronchitis, levofloxacin should only be used if no safer antibiotic will work.

🎯What it's used for▾
Levofloxacin is a fluoroquinolone antibiotic prescribed for adults with bacterial infections caused by susceptible bacteria. Main uses include:
- Pneumonia: Community-acquired and hospital-acquired (nosocomial)
- Skin and skin-structure infections: Both complicated and uncomplicated
- Urinary tract infections (UTIs): Complicated and uncomplicated
- Acute pyelonephritis (kidney infection)
- Chronic bacterial prostatitis
- Acute bacterial sinusitis
- Acute bacterial exacerbation of chronic bronchitis
- Inhalational anthrax (post-exposure prevention/treatment)
- Plague
⚙️How it works▾
Levofloxacin is a fluoroquinolone antibiotic. It works by blocking enzymes — specifically DNA gyrase and topoisomerase — that bacteria must use to copy and repair their genetic material. Without these enzymes working properly, the bacteria cannot reproduce and they die off. This makes levofloxacin effective against a wide range of both gram-positive and gram-negative bacteria.
To help prevent antibiotic resistance — where bacteria learn to survive the drug — levofloxacin should only be used for infections that are confirmed or strongly suspected to be bacterial in origin.
💊How it's taken▾
Levofloxacin tablets are taken by mouth once a day in most cases, with or without food. In a hospital or clinic setting, it may be given as an intravenous (IV) infusion. Drink plenty of water throughout the day while taking it.
- Take it at roughly the same time each day
- Complete the full course your prescriber prescribed — stopping early can allow the infection to return
- If you take antacids, iron, zinc, or multivitamins with minerals, space them at least 2 hours before or after your levofloxacin tablet
- Follow your prescriber's specific instructions, especially if you have kidney problems, as the dosing schedule may differ
🤒Side effects — in detail▾
The most commonly reported side effects include:
- Nausea
- Headache
- Diarrhea
- Insomnia (trouble sleeping)
- Constipation
- Dizziness
More serious reactions — tendon pain or rupture, numbness or tingling in the limbs, hallucinations, severe allergic reactions, irregular heartbeat, or signs of liver damage — require you to stop the medication immediately and seek medical care. These are not just uncommon inconveniences; they can be disabling or permanent.
⚠️Warnings & precautions▾
- Tendon damage: Levofloxacin increases the risk of tendinitis (inflamed tendons) and tendon rupture — most often the Achilles tendon, but also the shoulder, hand, and thumb. This can happen hours after the first dose or even months after finishing. Older adults and those on corticosteroids are at highest risk.
- Nerve damage (peripheral neuropathy): Numbness, tingling, pain, or weakness in the hands and feet can begin quickly and may become permanent. Stop the medication and call your doctor right away if this starts.
- Mental and nervous system effects: Hallucinations, severe anxiety, confusion, depression, insomnia, and intense headaches have all been reported. These can occur in anyone.
- Myasthenia gravis: Levofloxacin can dangerously worsen muscle weakness in people with this condition. It should not be used in anyone with a known history of myasthenia gravis.
- Heart rhythm changes (QT prolongation): Can cause dangerous irregular heartbeat. Extra caution is needed in older adults and people with low potassium or existing heart rhythm issues.
- Liver damage: Severe and sometimes fatal hepatotoxicity has been reported, more often in adults 65 and older.
- C. diff infection: Antibiotics can disrupt gut bacteria, leading to a serious diarrheal infection. Contact your doctor if diarrhea is severe or persistent.
- Severe allergic reactions: Can occur after just the first dose. Seek emergency help for hives, trouble breathing, or facial swelling.
🔀What it interacts with▾
Tell your pharmacist and doctor about all medications and supplements you take. Key interactions to know:
- Antacids (magnesium, aluminum), sucralfate, iron, zinc, multivitamins with minerals, or didanosine: These bind to levofloxacin in the gut and dramatically reduce how much is absorbed. Take them at least 2 hours before or after levofloxacin.
- Warfarin (a blood thinner): Levofloxacin can boost warfarin's effects, raising the risk of bleeding. Blood clotting tests (INR/prothrombin time) need to be monitored closely.
- Diabetes medications: Blood sugar can become unpredictably high or low. Monitor glucose carefully during treatment.
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Do NOT take levofloxacin if you are allergic to it or any other fluoroquinolone antibiotic (e.g., ciprofloxacin, moxifloxacin)
- Do NOT take if you have myasthenia gravis — it can cause a dangerous worsening of symptoms
- Tell your doctor if you have kidney problems — dose adjustments are required
- Tell your doctor if you have a history of heart rhythm problems or low potassium levels
- Older adults (65+) are at increased risk of tendon rupture, liver damage, and heart rhythm problems — use with extra care
- Pregnancy: Available data have not identified a clear risk of birth defects, but discuss the risks and benefits with your doctor
- Breastfeeding: Not recommended during treatment. Pump and discard breast milk during treatment and for 2 days after the last dose
- Children: Generally not for pediatric use except for inhalational anthrax (post-exposure) and plague in patients weighing at least 30 kg
🚑If you take too much▾
If too much levofloxacin is taken, the stomach should be emptied and the person kept well hydrated and monitored. Levofloxacin is not effectively removed by dialysis. Signs of a very large overdose may include tremors, convulsions, difficulty breathing, and decreased movement — seek emergency medical care immediately.
🔬Pharmacokinetics — how your body processes it▾
When taken by mouth as a tablet, levofloxacin is well absorbed and reaches peak levels in the blood within roughly 1 to 2 hours. The oral tablet and IV formulations produce very similar drug levels in the body, meaning the switch from IV to oral can be made smoothly when appropriate.
Levofloxacin has a half-life (the time it takes the body to clear half the drug) of approximately 6 to 8 hours in people with normal kidney function. The drug is cleared primarily by the kidneys, so people with reduced kidney function will process it more slowly and may need a lower or less frequent dose to avoid drug buildup.
📦How to store it▾
Store at 20°C to 25° C (68°F to 77° F) . Dispense in a well closed container as described in the USP.

📈 How widely Levofloxacin is used
A general measure of how commonly Levofloxacin is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Levofloxacin is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Levofloxacin prescribed? Of the 1,596 medications we measure, Levofloxacin ranks #270 by Medicaid prescriptions — more than 83% of them.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
Source: Medicaid State Drug Utilization Data (CMS), aggregated by generic ingredient — summed across every NDC (all brands, strengths, salt forms and dosage forms) of Levofloxacin, and across all states and both fee-for-service and managed-care claims. A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 40 of 627 listed Levofloxacin NDCs with Medicaid activity.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Levofloxacin — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Levofloxacin in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

🔬 Where this comes from
Core label, product, RxNorm, safety, and utilization data on this page come from the sources identified below. AI-written, editorial, and licensed sections are labeled separately.
How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 82 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Preferred Pharmaceuticals Inc is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition. For the exact wording of the linked representative label, view that label on DailyMed; some displayed composite sections may come from other in-scope SPL labels.
