Levaquin, known generically as levofloxacin, is a powerful antibiotic frequently used to combat a wide range of bacterial infections. From respiratory infections to urinary tract infections, it’s a go-to option for many healthcare providers. However, the right dosage depends on the specific infection, patient characteristics, and other health factors.
Understanding how much Levaquin to take and when can help maximize its effectiveness while minimizing risks. This guide breaks down the typical doses, schedules, and important considerations to keep in mind.

For community-acquired pneumonia or acute bacterial sinusitis, adults typically take 500 mg once daily for 7 to 14 days. In more severe cases, such as hospital-acquired pneumonia, the dose may increase to 750 mg once daily for up to 14 days.
Uncomplicated UTIs often require 250 mg once daily for 3 days. For complicated infections or pyelonephritis, 500 mg to 750 mg once daily for 7 to 14 days is common. Treatment length depends on infection severity and patient response.
Adults usually receive 500 mg once daily for 7 to 14 days. The dose can be adjusted based on clinical response and infection severity.
Chronic bacterial prostatitis treatment typically involves 500 mg once daily for 28 days or longer, depending on the physician’s assessment.
Adult dosing is generally straightforward but must be tailored to the infection type and patient factors. The most common doses are 250 mg, 500 mg, or 750 mg once daily. The higher doses are reserved for more serious infections or when a rapid response is needed.
Levaquin tablets should be taken at the same time each day, with or without food. It’s important to complete the entire prescribed course even if symptoms improve early.
Levaquin use in children is limited due to potential side effects on developing joints and tendons. When prescribed, dosing is weight-based and carefully monitored by a healthcare provider. It’s typically reserved for serious infections where other antibiotics are not suitable.
If a dose is missed, take it as soon as you remember. If it’s close to the time for the next dose, skip the missed one; do not double up to catch up. Maintaining a consistent dosing schedule helps keep effective drug levels in the body and prevents resistance.
Levaquin is primarily eliminated by the kidneys. Patients with reduced kidney function require dose adjustments to prevent drug accumulation and toxicity. Your doctor will calculate the appropriate dose based on creatinine clearance or estimated glomerular filtration rate (eGFR).
Patients with central nervous system disorders, seizures, or a history of tendon problems should discuss risks with their healthcare provider before starting Levaquin. Dose adjustments may be necessary depending on overall health status.
Taking more than the prescribed dose of Levaquin can lead to serious side effects, including seizures, heart rhythm disturbances, and tendon rupture. If an overdose is suspected, seek emergency medical attention immediately.
Levaquin carries warnings about tendonitis and tendon rupture, especially in older adults and those on corticosteroids. It may also cause nerve damage and exacerbate muscle weakness in people with myasthenia gravis.
Take Levaquin exactly as prescribed by your healthcare provider.
Avoid taking it with dairy products or calcium-fortified juices close to dosing time, as they can reduce absorption.
Stay hydrated to help prevent kidney problems.
Report any unusual muscle pain, tendon swelling, or neurological symptoms promptly.
Do not stop the medication early, even if you feel better.

No, Levaquin is typically prescribed once daily due to its long half-life. Taking it more frequently can increase side effects without improving effectiveness.
Levaquin can interact with certain drugs, including antacids, blood thinners, and corticosteroids. Always inform your doctor about all medications you are taking.
Many patients notice improvement within a few days, but it’s important to complete the full course to fully eradicate the infection.
