Moxifloxacin
Summary
Moxifloxacin is used to treat bacterial infections, which include respiratory tract infections like pneumonia and bronchitis, and skin infections. It is often prescribed when other antibiotics are not suitable or effective.
Moxifloxacin works by inhibiting bacterial enzymes called DNA gyrase and topoisomerase IV, which are essential for bacterial DNA replication and repair. This action stops bacteria from multiplying and leads to their death.
The usual dose of Moxifloxacin for adults is 400 mg once daily. It is typically taken for a short duration, often 5 to 14 days, depending on the infection being treated. It can be taken with or without food.
Common adverse effects of Moxifloxacin include nausea, diarrhea, and dizziness. These side effects are usually mild and occur in a small percentage of people taking the medication.
Moxifloxacin can cause tendon damage, including tendonitis and tendon rupture, especially in older adults. It may also cause nerve damage and heart rhythm changes. It is contraindicated in people with a history of tendon disorders related to quinolone use.
