Levofloxacin
Levofloxacin is a powerful oral antibiotic used for specific bacterial infections. It treats things like pneumonia, urinary tract infections, some skin infections, and certain sinus or lung infections when other drugs aren't suitable. This page gives clear, practical facts you can use right away: how it works, common doses, major safety concerns, and smart tips if you’re thinking about buying it online.
How levofloxacin works
Levofloxacin belongs to the fluoroquinolone family. It kills bacteria by blocking enzymes they need to copy their DNA. That makes it effective against many common bacteria, and it usually works fast—often within a day or two you may feel better. But it won’t touch viruses like the flu or common colds, so doctors avoid using it unless tests or symptoms point to a bacterial cause.
Typical adult doses run from 250 mg to 750 mg once daily, depending on the infection and kidney function. Treatment length varies—some infections need 5 days, others 7–14 days. Your prescriber will pick the right dose for you based on the infection type and your medical history.
Safety, interactions and buying tips
Know the big risks. Levofloxacin can cause tendon pain or even tendon rupture—this risk is higher in older adults and in people taking corticosteroids. It can also affect the heart rhythm (QT prolongation) and the nervous system, causing dizziness, confusion, or mood changes in some people. Stop the drug and get medical help if you get sudden tendon pain, severe dizziness, breathing trouble, or signs of an allergic reaction (rash, swelling).
Watch for common interactions: antacids, iron supplements, and sucralfate lower absorption—take levofloxacin at least 2 hours before or 2 hours after these. It can raise INR if you’re on warfarin, so lab checks are needed. Avoid mixing with other QT-prolonging drugs when possible. If you have kidney disease, doses need adjusting.
Antibiotic resistance matters. Only use levofloxacin when a clinician prescribes it. Don’t stop early unless your doctor tells you to—finish the course unless severe side effects occur.
Thinking of buying online? Only use pharmacies that require a prescription, show a verifiable license, list a real address and phone number, and use secure checkout (HTTPS). Avoid sites that sell without a prescription or offer suspiciously low prices. If unsure, call the pharmacy or ask your doctor for a trusted supplier. Never use pills of unknown origin—counterfeit antibiotics can be ineffective or dangerous.
If you miss a dose, take it as soon as you remember but skip it if the next dose is near. Don’t double up. Keep a list of your medicines and allergies, and tell your prescriber about any tendon pain, heart issues, or nerve symptoms while on levofloxacin. When used correctly, it can clear tough infections—used carelessly, it can cause lasting harm. Ask questions and keep open lines with your clinician or pharmacist.
