What is the standard dosing for Levaquin in cases of community-acquired pneumonia (CAP) or acute sinusitis?

Levaquin, which is a fluoroquinolone antibiotic known generically as levofloxacin, is commonly used to treat various bacterial infections, including community-acquired pneumonia (CAP) and acute sinusitis. The standard dosing regimen for Levaquin in the case of CAP is generally 750 mg administered once daily for a duration of 5 days. This higher dose is effective for treating more severe infections and helps ensure adequate penetration of the drug into the lungs, allowing for effective eradication of the bacteria causing pneumonia.

In the context of acute sinusitis, while other dosing regimens may be considered based on the severity of the infection and patient-specific factors, 750 mg daily for 5 days is also a common approach due to its broad-spectrum activity and favorable safety profile.

It's important to use the appropriate dosage and duration to balance effectiveness with potential side effects and to help prevent the development of antibiotic resistance. Thus, the choice of 750 mg daily for 5 days aligns with established clinical guidelines for treating these specific infections.
