What is Levoxin?
Levoxin 750 mg tablet by Incepta Pharmaceuticals Ltd. contains Levofloxacin, a broad-spectrum fluoroquinolone antibiotic. It is prescribed for more serious or resistant bacterial infections, including certain pneumonias and chest infections, complicated urinary and kidney infections, sinusitis, and some skin infections. Levoxin is a prescription-only medicine and must be taken strictly under a registered doctor's supervision.
Levofloxacin works by blocking the bacterial enzymes (DNA gyrase and topoisomerase IV) that bacteria need to copy and repair their DNA. Without these enzymes the bacteria cannot reproduce and quickly die. Because it acts only on bacteria, Levoxin has no effect on viral illnesses such as colds, flu, or most coughs and sore throats.
Indications
- Community-acquired pneumonia and chest infections
- Complicated urinary tract and kidney infections
- Acute bacterial sinusitis
- Skin and soft-tissue infections
- Some chronic prostate infections
- Certain serious infections where other antibiotics are unsuitable
Dosage & Administration
The dose of Levoxin depends on the infection and its severity. A typical adult dose is 250-750 mg once daily for 5 to 14 days, with the exact strength and length decided by the doctor. Swallow the tablet with plenty of water and keep yourself well hydrated during treatment.
Levoxin is generally not used in children except in special situations decided by a specialist. Do not take it within 2 hours of milk, antacids, iron, or zinc, as these reduce absorption. Take it at the same time each day and finish the full course.
Side Effects
Many people tolerate Levofloxacin well, but side effects can occur. Common ones include:
- Nausea, diarrhoea, or abdominal discomfort
- Headache, dizziness, or sleep disturbance
- Skin rash
Rare but serious effects include tendon pain or rupture (especially the Achilles tendon), nerve damage with tingling or numbness, mood or confusion changes, seizures, and irregular heartbeat. Stop Levoxin and seek medical help immediately if you notice tendon pain, severe mood changes, numbness, or a serious allergic reaction.
Precautions & Warnings
Levoxin is a prescription-only antibiotic — never self-medicate. Fluoroquinolones are powerful and are usually reserved for when other antibiotics are unsuitable, so take Levoxin only when a registered doctor prescribes it; never buy it over the counter or share it. Always complete the full prescribed course, even after you feel better, because stopping early lets the toughest bacteria survive and become resistant.
Tell your doctor about tendon problems, epilepsy, nerve disorders, diabetes, kidney disease, or heart-rhythm problems. Antibiotic resistance is a serious national crisis in Bangladesh, and careless use of strong antibiotics like Levofloxacin accelerates it.
Drug Interactions
Tell your doctor about everything you take. Important interactions with Levofloxacin include:
- Milk, antacids, iron, zinc, and calcium — reduce absorption; separate by at least 2 hours
- NSAID painkillers — may increase the risk of seizures
- Warfarin — increased bleeding risk
- Medicines that affect heart rhythm (QT-prolonging drugs)
- Diabetes medicines — blood sugar can rise or fall
Contraindications
Do not take Levoxin if you:
- Are allergic to levofloxacin or other fluoroquinolone antibiotics
- Have previously had tendon problems after a fluoroquinolone
- Have epilepsy or a history of seizures (unless your doctor decides otherwise)
It is generally avoided in children, adolescents, and during pregnancy or breastfeeding, and used cautiously in people with myasthenia gravis, diabetes, or heart-rhythm disorders.
Pregnancy & Lactation
Levofloxacin is generally not recommended during pregnancy unless there is no safer alternative, because of concerns about its effect on developing joints and cartilage. Tell your doctor if you are pregnant or planning a pregnancy so a safer antibiotic can be chosen.
The drug passes into breast milk, so it is usually avoided while breastfeeding. Your doctor may advise an alternative antibiotic or discuss pausing breastfeeding during treatment.
Storage Conditions
Store Levoxin in a cool, dry place below 30°C, away from direct sunlight and moisture, in its original pack. Keep it well out of the reach of children. Do not use the medicine after its expiry date, and return any leftover tablets to a pharmacy rather than keeping them for future use.
Frequently Asked Questions
Can I stop Levoxin early once I am feeling well again?
No. Levofloxacin is a strong antibiotic used for serious or stubborn infections, and symptoms often improve well before the bacteria are fully cleared. Stopping Levoxin early lets the most resistant bacteria survive and multiply, so the infection can return in a form that no longer responds to this or similar antibiotics. Take every dose for the full course your doctor prescribed. Antibiotic resistance is a serious national crisis in Bangladesh, and completing strong antibiotics properly is essential to keep them working.
I have tingling, numbness, or anxiety since starting Levoxin — should I worry?
Tell your doctor promptly. Fluoroquinolones like levofloxacin can occasionally affect the nerves and the central nervous system, causing tingling, numbness, dizziness, sleeplessness, anxiety, confusion, or low mood. Rarely they can trigger seizures. Sudden tendon pain or swelling, especially in the ankle, also needs urgent attention. Do not ignore these symptoms or simply push through the course — contact your doctor, who will decide whether to stop Levoxin and choose a safer alternative. Acting early helps prevent lasting problems.
Why must I keep milk and antacids away from my Levoxin dose?
Calcium in milk and dairy, and the minerals in antacids, iron, and zinc supplements, bind to levofloxacin in the gut and block its absorption. This can leave too little active medicine in your blood to clear the infection, so Levoxin may fail. Take it at least 2 hours before, or 6 hours after, these products, and swallow it with plain water. Staying well hydrated throughout the course also supports the medicine and reduces the small chance of side effects.
