Key takeaways

Xenleta (lefamulin) and Avelox (moxifloxacin) are both antibiotics, but they belong to different classes and have distinct uses and side effects. Xenleta is a pleuromutilin antibiotic specifically used to treat community-acquired bacterial pneumonia (CABP) in adults. Avelox, on the other hand, is a fluoroquinolone antibiotic that treats a wider range of infections, including infections of the lungs, skin, gut, and sinuses. Both Xenleta and Avelox are available as tablets and an injection. Xenleta tablets should be taken on an empty stomach, whereas Avelox tablets can be taken with or without food. While Xenleta is only available as a brand-name medication, Avelox is available in a generic form. Both medications have serious side effects, but Avelox has a broader range of potential risks, including tendon rupture, nerve damage, and severe allergic reactions.
