LEVOBACT-500

# LEVOFLOXACIN 500 MG ## Short Description **Levofloxacin 500 mg** is a **fluoroquinolone antibiotic** used to treat certain susceptible bacterial infections. It works by interfering with bacterial enzymes required for DNA replication and repair, thereby preventing bacterial growth and survival. Levofloxacin may be prescribed for selected **respiratory tract, urinary tract, skin and soft-tissue, and other bacterial infections** when appropriate. It does **not** treat viral infections such as the common cold or influenza. > **Important:** Fluoroquinolone antibiotics can cause potentially serious and sometimes long-lasting adverse effects. They should generally be reserved for infections where levofloxacin is an appropriate treatment option. ## Key Benefits * Treats a range of **susceptible bacterial infections**. * Has activity against several Gram-positive and Gram-negative bacteria. * May be used for selected respiratory bacterial infections. * May be used for certain urinary tract and kidney infections. * Provides systemic antibacterial treatment when oral therapy is appropriate. * Convenient once-daily dosing is used for many adult indications. ## Uses / Indications Depending on the infection, bacterial susceptibility, and local prescribing guidance, levofloxacin may be used for: * **Community-acquired bacterial pneumonia**. * Certain bacterial respiratory tract infections. * **Complicated urinary tract infections**. * **Acute pyelonephritis** (kidney infection). * Certain skin and soft-tissue infections. * Chronic bacterial prostatitis. * Other susceptible bacterial infections when specifically indicated. Levofloxacin may also be used for certain specialized infections under medical supervision. ### Important Levofloxacin should **not be routinely used for uncomplicated infections when safer effective alternatives are available**, because fluoroquinolones can cause serious adverse effects. It is ineffective against viral infections such as: * Common cold. * Influenza. * Most viral sore throats. ## How It Works Levofloxacin is a **fluoroquinolone antibiotic**. It inhibits bacterial enzymes called: * **DNA gyrase**. * **Topoisomerase IV**. These enzymes are essential for bacterial DNA replication, repair, and maintenance. By blocking these enzymes, levofloxacin interferes with bacterial DNA processes and ultimately causes bacterial cell death. ## Dosage & Administration The dose and treatment duration depend on the **type and severity of infection, kidney function, age, bacterial susceptibility, and clinical response**. For many adult infections, commonly used regimens include: * **500 mg once daily**, although some infections require different doses or durations. * Take the medicine exactly as prescribed. * It can generally be taken **with or without food**. * Swallow the tablet with sufficient water. * Try to take it at approximately the same time each day. * Complete the prescribed course unless your healthcare professional tells you to stop. * **Do not self-treat with leftover antibiotics.** ### Important Administration Instructions Do not take levofloxacin at the same time as products containing significant amounts of: * Iron. * Zinc. * Magnesium. * Aluminum. * Calcium-containing antacids or mineral supplements. These can reduce levofloxacin absorption. Generally, separate these products from levofloxacin by **at least 2 hours before or after**, following the specific product instructions. ### If You Miss a Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses together.** ### Kidney Impairment Levofloxacin is primarily eliminated through the kidneys. Patients with reduced kidney function may require **dose adjustment**. ## Side Effects Common side effects may include: * Nausea. * Diarrhea. * Headache. * Dizziness. * Insomnia. * Abdominal discomfort. * Vomiting. * Changes in taste. ### Serious Side Effects Fluoroquinolones, including levofloxacin, can cause serious adverse reactions.

Seek urgent medical attention for sudden severe chest, abdominal, or back pain. ## Precautions & Warnings ### Tendon Injury Levofloxacin can cause **tendinitis and tendon rupture**. The risk is higher in: * Older adults. * People taking corticosteroids. * People with kidney disease. * Patients with a history of tendon disorders. * People receiving certain transplant-related treatments. Stop exercising and contact your healthcare professional if tendon pain or swelling develops. ### Peripheral Neuropathy Nerve damage can occur during or after fluoroquinolone treatment. Report: * Burning. * Tingling. * Numbness. * Weakness. * Altered sensation. Prompt medical evaluation is important if these symptoms develop. ### Central Nervous System Effects Levofloxacin may cause: * Dizziness. * Anxiety. * Insomnia. * Confusion. * Hallucinations. * Tremors. * Seizures in susceptible individuals.

Protect exposed skin from excessive sunlight and discontinue sun exposure if significant skin reactions develop. ## Drug Interactions ### Antacids and Mineral Supplements Antacids or supplements containing: * Aluminum. * Magnesium. * Iron. * Zinc. can significantly reduce levofloxacin absorption. Separate administration according to the product instructions, generally by **at least 2 hours**. ### Sucralfate Sucralfate can interfere with levofloxacin absorption and should be taken separately. ### Warfarin Levofloxacin may increase the effect of **warfarin** in some patients. Additional monitoring of INR may be required. ### Corticosteroids Combining levofloxacin with corticosteroids may increase the risk of **tendon injury or tendon rupture**. ### Diabetes Medicines Levofloxacin can affect blood glucose levels in people taking insulin or other diabetes medicines. ### QT-Prolonging Medicines The risk of abnormal heart rhythms may increase when levofloxacin is combined with other medicines that prolong the QT interval. ### NSAIDs Some NSAIDs may increase the risk of central nervous system stimulation or seizures when combined with fluoroquinolones.
