What Factors Affect Levaquin® Dosage?

Appropriate Levaquin® dosage can depend on the type of infection being treated, a patient’s overall health, and the patient’s age. This antibiotic drug is only effective against infections known to be caused by bacteria, and in some cases, the bacteria may be resistant. A doctor may recommend a susceptibility culture to determine which medication would be most appropriate for a patient. In viral, fungal, and other infections, a different medication must be used.

One important consideration is the kind of infection the patient has and its severity. Levaquin® can be effective for the treatment of a range of bacterial infections in the sinus passages, airways, and urinary tract, among other locations. For severe infections, a higher dosage may be necessary, while mild problems like a low-risk urinary tract infection might need a low dose. Starting Levaquin® dosage can range between 250 and 750 milligrams every 24 hours for adult patients and the care provider may use some judgment when recommending an appropriate dose to attack the infection quickly and aggressively.

Pediatric and underweight patients may need a dosage adjustment. The doctor can calculate a weight-based Levaquin® dosage to ensure the patient gets a safe amount. Adjustments may also be necessary for patients with kidney damage. If the kidney function is compromised, the doctor may recommend a high loading dose followed by a reduced dosage to protect the kidneys. Blood work can determine whether the kidneys are impaired enough to require a change to the medication regimen.

Other medications, along with preparations patients can buy over the counter, like vitamins and antacid tablets, can interfere with the absorption of this medication. For this reason, a doctor may recommend taking it at a specific time each day, and allowing at least two hours before and after the Levaquin® dose before taking other drugs. If the Levaquin® dosage is likely to cause a medication conflict, the patient may also need to temporarily stop taking a drug while on the antibiotic.

This medication has been linked with heart, liver, and tendon damage. Patients who notice side effects like irregular heartbeat, muscle soreness, and abdominal tenderness should contact their doctors. The doctor can determine if the Levaquin® dosage is a cause for concern. It may be possible to lower the dose or switch medications to prevent damage. Medications shouldn’t be stopped without consulting a doctor or nurse hotline, if the doctor is not available, because patients could put themselves at risk of complications.
