FAQs About Moxifloxacin Eye Drops

2. Can I use moxifloxacin for viral or fungal eye infections?
No, moxifloxacin is only effective against bacterial infections. It won’t work for viral infections like those caused by adenovirus or fungal eye infections. Using antibiotics when not needed can lead to antibiotic resistance. Always confirm the type of infection with your doctor.

4. Can I wear contact lenses while using moxifloxacin eye drops?
It’s not recommended to wear contact lenses while treating an eye infection. The preservatives in the drops may irritate your eyes. Contact lenses can trap bacteria, slowing healing. Wait at least 15 minutes after applying the drops before putting in your lenses. Always check with your doctor for specific advice.
