Levofloxacin: What It Is, How It Works, and When to Use It

Levofloxacin is a prescription antibiotic that belongs to the fluoroquinolone class. It attacks bacteria by stopping their DNA from copying, which kills the germs and clears the infection. Doctors often choose it for lung infections, urinary tract infections, skin infections, and some sexually transmitted infections.

If you’ve been handed a bottle of Levofloxacin, you’re probably wondering how to take it correctly and what to expect. Below we break down the basics – the right dose, the most common side effects, and the safety tips you need to keep in mind.

Typical Dosage and How to Take It

The exact dose depends on the infection you’re treating. For most adults, the usual course is 500 mg once a day for seven to fourteen days. Some doctors start with a higher loading dose of 750 mg, especially for severe pneumonia. Always follow the label or your doctor’s instructions – don’t skip doses or stop early even if you feel better.

Levofloxacin comes in tablets, oral solution, and an IV form for hospital use. Swallow tablets with a full glass of water. You can take it with or without food, but avoid dairy or calcium‑rich meals right before and after the dose, as they can lower absorption.

Common Side Effects and Warning Signs

Most people tolerate Levofloxacin well, but you might notice mild headaches, nausea, or a bit of diarrhea. These usually fade within a few days. If you develop a rash, joint pain, or trouble sleeping, let your doctor know.

Serious warnings include tendon problems (especially in the Achilles tendon), nerve issues that feel like tingling or numbness, and irregular heart rhythms. If you feel sudden sharp pain in a tendon, see a doctor right away. The risk is higher if you’re older, take steroids, or have kidney problems.

Because Levofloxacin can affect blood sugar, people with diabetes should monitor glucose closely. Also, avoid sunlight for a few days if you notice increased photosensitivity – wear sunscreen and sunglasses.

Never share your medication with anyone else, and keep it out of reach of children. Store tablets at room temperature, away from moisture.

In summary, Levofloxacin is a powerful tool against a range of bacterial infections when used correctly. Stick to the prescribed dose, watch for side effects, and reach out to your healthcare provider if anything feels off. By staying informed, you’ll get the most benefit from this antibiotic while minimizing risks.
