Levofloxacin 500 mg product overview
Levoflox 500 Tablet contains levofloxacin, an antibacterial medicine belonging to the fluoroquinolone class. Doctors may prescribe levofloxacin for certain infections caused by bacteria that are susceptible to the medicine.
Levofloxacin works by interfering with bacterial enzymes needed for DNA replication and repair. This action stops susceptible bacteria from multiplying and contributes to bacterial cell death.
The 500 mg strength is only one available tablet strength. The correct strength, dosing frequency and treatment period depend on several factors, including:
- The diagnosed infection
- The suspected or confirmed bacteria
- Local resistance patterns
- Laboratory or culture results
- Kidney function
- Age and medical history
- Other medicines being taken
- Prior antibiotic exposure
- The seriousness and location of the infection
A 500 mg tablet is not automatically appropriate for every infection. Patients should not select a dose based on body weight, internet advice or a previous prescription.

Can you buy Levofloxacin 500 mg online?
People searching for “levofloxacin 500 mg buy online” should first confirm that the pharmacy follows lawful prescription and dispensing practices.
A legitimate online medicine order should include:
- A valid prescription when legally required
- Review by a qualified pharmacy professional
- Clear product and manufacturer details
- Accurate strength and pack information
- Secure handling of medical and payment data
- Access to customer or pharmacy support
- Transparent shipping, refund and privacy terms
- No claim that the medicine will work for every infection
A website should not encourage a patient to bypass medical assessment. It should also not claim that levofloxacin is suitable merely because the patient has fever, painful urination, cough, sinus pressure or another symptom.
Medical evaluation matters because these symptoms may result from viral infections, resistant bacteria, noninfectious inflammation or conditions that need different treatment.
Levofloxacin should be ordered only when it has been prescribed for the named patient and the patient has received instructions on how to take it.
What is Levofloxacin 500 mg used for?
Levofloxacin may be prescribed for certain bacterial infections when the responsible organism is susceptible and when the prescriber considers the medicine appropriate.
Depending on local approval, clinical guidance and patient circumstances, these may include certain cases of:
- Community-acquired pneumonia
- Hospital-acquired pneumonia
- Complicated urinary tract infection
- Acute pyelonephritis, which is a kidney infection
- Chronic bacterial prostatitis
- Complicated skin and skin-structure infection
- Some uncomplicated skin infections
- Acute bacterial sinusitis
- Acute bacterial worsening of chronic bronchitis
- Certain uncommon exposure-related infections, including anthrax or plague
This list does not mean that levofloxacin is the first choice for every listed condition.
Because fluoroquinolones can cause serious adverse effects, official labeling may reserve their use for some uncomplicated infections when other suitable options are unavailable. The treating clinician should take account of current guidelines, culture results and the patient’s risk factors.
Levofloxacin is not appropriate for every bacterial strain. Antibiotic susceptibility can differ by organism, patient, country, region and healthcare setting.
What Levofloxacin does not treat
Levofloxacin does not work against viral infections. It should not be used to treat:
- The common cold
- Influenza
- Most viral sore throats
- Most cases of viral bronchitis
- Viral stomach infections
- COVID-19 unless a clinician diagnoses a separate bacterial infection that needs antibiotic treatment
Taking an antibiotic when it is not needed exposes the patient to side effects without providing a bacterial-treatment benefit.
Unnecessary antibiotic use also contributes to antimicrobial resistance. Resistance develops when bacteria change in ways that allow them to survive medicines intended to kill them or stop their growth.
The US Centers for Disease Control and Prevention states that antibiotics can save lives, but every use can cause adverse effects and contribute to antimicrobial resistance.
Read CDC guidance about antibiotic prescribing and use
How Levofloxacin works
Bacteria need to copy and maintain their genetic material to grow and survive. Levofloxacin blocks bacterial enzymes known as DNA gyrase and topoisomerase IV.
These enzymes play important roles in:
- Copying bacterial DNA
- Repairing bacterial DNA
- Separating genetic material during cell division
- Maintaining the structure of bacterial chromosomes
By interfering with these processes, levofloxacin prevents susceptible bacteria from reproducing correctly and leads to bacterial death.
This mechanism does not make levofloxacin suitable for every infection. The medicine must reach the infected tissue in an effective concentration, and the bacteria must be susceptible to it.
Laboratory cultures may help identify the organism and test which antibiotics are likely to work. In urgent situations, a clinician may begin treatment before results are available and later change the medicine when more information is known.
How to take Levofloxacin 500 mg
Take levofloxacin exactly as directed by the prescriber and shown on the dispensing label.
General administration information may include the following:
- Swallow the tablet with water.
- Take it at approximately the same time each day.
- Levofloxacin tablets may generally be taken with or without food.
- Drink adequate fluids unless a clinician has advised fluid restriction.
- Do not take more than the prescribed amount.
- Do not extend the course without medical advice.
- Do not give the tablets to another person.
- Do not save leftover tablets for a future illness.
The dose and course length depend on the diagnosed infection and the patient’s medical status. Kidney function is particularly important because levofloxacin is cleared largely through the kidneys.
Patients with reduced renal function may require a different dosing schedule. Taking a standard schedule when dose adjustment is needed could raise medicine exposure and the risk of adverse reactions.
The official DailyMed prescribing information states that dose adjustment is required for some patients whose creatinine clearance is below 50 mL/min.
See official DailyMed levofloxacin prescribing information
Should Levofloxacin be taken with dairy products?
The tablet may generally be taken with food, but certain products and medicines can reduce levofloxacin absorption when taken too close together.
Patients should tell their pharmacist if they use:
- Antacids containing magnesium or aluminum
- Iron supplements
- Zinc supplements
- Sucralfate
- Multivitamins containing metal minerals
- Didanosine preparations containing aluminum or magnesium
These products may bind to levofloxacin in the digestive tract and reduce the amount absorbed into the body.
Official instructions commonly advise separating oral levofloxacin from these products by at least two hours. Follow the timing stated by the prescribing professional or dispensing pharmacist.
Dairy foods alone do not necessarily have the same restriction as mineral supplements, but taking levofloxacin at the same time as heavily mineral-fortified products may need discussion with a pharmacist. The product label and the pharmacist’s directions should take priority over general online information.
What should you do after a missed dose?
Follow the directions provided with the prescription.
As a general rule, a missed dose may be taken when remembered unless it is close to the time for the next scheduled dose. Do not take two doses together to compensate for a missed tablet unless a medical professional specifically instructs you to do so.
Contact a pharmacist when the timing is uncertain, particularly when:
- More than one dose was missed
- The prescription has an unusual schedule
- The patient has kidney disease
- Vomiting occurred after taking the tablet
- The patient accidentally took an extra dose
- Serious symptoms are present
Missing doses or changing the schedule may affect treatment. However, doubling a dose can raise the risk of side effects.
Common side effects of Levofloxacin
Some people experience mild or moderate side effects while taking levofloxacin.
Reported reactions can include:
- Nausea
- Diarrhea
- Headache
- Dizziness
- Constipation
- Trouble sleeping
- Stomach discomfort
A patient should speak with the prescriber or pharmacist when side effects are persistent, worsening or difficult to manage.
Diarrhea can occur with many antibiotics. However, severe, persistent or bloody diarrhea may indicate a more serious bowel reaction, including infection associated with Clostridioides difficile.
Such diarrhea can occur during antibiotic treatment or after the antibiotic has been stopped. Patients with severe diarrhea, fever, abdominal pain, dehydration or blood in the stool should obtain medical care rather than treating the condition themselves with over-the-counter anti-diarrheal medicine.
Serious tendon warning
Levofloxacin and other fluoroquinolones have been linked to tendinitis and tendon rupture.
A tendon is a strong band of tissue connecting muscle to bone. The Achilles tendon near the heel is frequently discussed in fluoroquinolone warnings, but damage can affect other tendons, including those in the shoulder, hand, biceps and thumb.
Tendon injury can happen:
- During treatment
- Soon after starting treatment
- Several months after the medicine has been stopped
- In people of different ages
Risk may be higher in people who:
- Are older than 60
- Take corticosteroid medicines
- Have received a kidney, heart or lung transplant
- Have kidney disease
- Take part in strenuous physical activity
- Have a history of tendon disorders
Seek prompt medical advice for tendon pain, tenderness, swelling, stiffness or difficulty moving a joint. Avoid exercise involving the affected area until a clinician has assessed the symptoms.
Do not continue taking the medicine after a suspected serious reaction without obtaining medical instructions.
Nerve-damage warning
Fluoroquinolones may cause peripheral neuropathy, a form of nerve damage. In some cases, symptoms may begin soon after treatment starts and may not fully resolve.
Possible signs include:
- Burning pain
- Tingling
- Numbness
- Unusual sensitivity to touch
- Weakness
- Changes in temperature sensation
- Reduced ability to feel pain
Patients who develop new nerve symptoms should contact a medical professional promptly. Early assessment is important because continued exposure may worsen the condition.
The MedlinePlus drug information page includes warnings concerning tendon injury, peripheral neuropathy and nervous-system reactions.
Read the MedlinePlus levofloxacin patient information
Brain and nervous-system reactions
Levofloxacin may cause central nervous system and psychiatric reactions, sometimes after the first dose.
Reported problems include:
- Seizures
- Tremors
- Restlessness
- Anxiety
- Confusion
- Hallucinations
- Depression
- Trouble concentrating
- Severe sleep disturbance
- Suicidal thoughts or behavior
- Increased pressure inside the skull
- Dizziness or light-headedness
The risk can be affected by a history of seizures, brain disorders, reduced kidney function or medicines that lower the seizure threshold.
Any severe behavioral, mood or neurological change needs urgent medical attention. Thoughts of self-harm or suicide require immediate emergency support.
Myasthenia gravis warning
Levofloxacin may worsen muscle weakness in people with myasthenia gravis.
This reaction can affect the muscles needed for breathing and may become life-threatening. Patients with myasthenia gravis should tell the prescriber before taking any fluoroquinolone antibiotic.
Seek emergency care for:
- New or worsening breathing difficulty
- Trouble swallowing
- Marked muscle weakness
- Drooping eyelids with generalized weakness
- Difficulty speaking caused by muscle weakness
A patient should not rely on product-page information to decide whether the medicine is safe with this condition.
Blood-sugar changes
Levofloxacin may cause high or low blood sugar. This issue is especially relevant for people with diabetes who take insulin or other glucose-lowering medicines.
Possible low-blood-sugar symptoms include:
- Sweating
- Shaking
- Hunger
- Confusion
- Weakness
- Dizziness
- Rapid heartbeat
- Irritability
- Loss of consciousness in severe cases
High blood sugar may cause increased thirst, frequent urination, fatigue or blurred vision.
People with diabetes should discuss blood-glucose monitoring with their clinician. Severe or unexplained glucose changes need prompt medical care.
Heart-rhythm considerations
Levofloxacin can affect the electrical activity of the heart and may lengthen the QT interval in susceptible patients.
Tell the prescriber about:
- A history of QT prolongation
- Irregular heartbeat
- Slow heartbeat
- Heart failure
- Recent heart attack
- Low potassium or magnesium levels
- A family history of certain rhythm disorders
- Any medicine known to affect heart rhythm
Seek urgent medical care for fainting, severe dizziness, chest discomfort or a rapid or irregular heartbeat.
A medication review is particularly important because patients may not know that another prescription or over-the-counter product affects the QT interval.
Aortic aneurysm and dissection concern
Fluoroquinolones have been associated with rare but serious problems involving the aorta, the body’s largest artery.
People may have higher baseline risk when they are older or have conditions such as:
- Known aortic aneurysm
- High blood pressure
- Certain inherited connective-tissue disorders
- Significant blood-vessel disease
- A history of aneurysm
- Atherosclerosis
Seek emergency care for sudden, severe and persistent pain in the chest, back or abdomen.
Patients with known risk factors should discuss them with the prescriber before beginning levofloxacin.
Allergic and severe skin reactions
Do not take levofloxacin when there is a known allergy to levofloxacin or another quinolone antibiotic unless a qualified specialist has assessed the situation.
Emergency symptoms of a serious allergic reaction may include:
- Swelling of the face, lips, tongue or throat
- Difficulty breathing
- Widespread hives
- Fainting
- Rapid worsening after a dose
Serious skin reactions may begin with a rash, blistering, peeling skin, mouth sores, fever or painful red skin.
Stop seeking online product advice and obtain urgent medical care when these symptoms occur.
Liver problems
Rare but serious liver reactions have been reported with levofloxacin.
Contact a medical professional promptly for:
- Yellowing of the skin or eyes
- Dark urine
- Pale stools
- Severe fatigue
- Loss of appetite
- Persistent nausea
- Pain in the upper-right abdomen
- Unusual bruising or bleeding
A history of liver disease and all current medicines should be disclosed during the prescription review.
Sun sensitivity
Levofloxacin may make the skin more sensitive to sunlight or artificial ultraviolet light.
While taking it:
- Limit unnecessary direct sun exposure.
- Avoid tanning beds and sun lamps.
- Wear protective clothing outdoors.
- Ask a pharmacist about suitable sunscreen.
- Report severe redness, swelling or blistering.
A significant skin reaction may need medical evaluation.
Who should speak with a clinician before taking Levofloxacin?
A detailed medical review is important for anyone with:
- Kidney disease
- Myasthenia gravis
- Tendon disease or prior tendon rupture
- Seizure disorder
- Brain or nervous-system disease
- Diabetes
- Heart-rhythm problems
- Low potassium or magnesium
- Aortic aneurysm or major vascular disease
- Rheumatoid arthritis or connective-tissue disease
- Liver disease
- A previous serious reaction to a quinolone antibiotic
- Pregnancy or plans to become pregnant
- Breastfeeding
- An organ transplant
- Current corticosteroid treatment
Children and adolescents generally require specialist consideration because fluoroquinolones can affect joints and musculoskeletal tissues. Their use may be limited to particular situations where the expected benefit justifies the risk.
Levofloxacin medicine interactions
A patient should provide the clinician and pharmacist with a full list of:
- Prescription medicines
- Nonprescription medicines
- Vitamins
- Mineral products
- Herbal products
- Sports supplements
- Recently stopped medicines
Potentially important interaction categories include:
- Corticosteroids, which may raise tendon-injury risk
- Medicines that affect the QT interval
- Insulin and oral diabetes medicines
- Warfarin and other anticoagulants
- Nonsteroidal anti-inflammatory drugs
- Theophylline
- Probenecid
- Cimetidine
- Antacids containing magnesium or aluminum
- Iron and zinc supplements
- Sucralfate
- Multivitamins containing minerals
An interaction does not always mean that two medicines can never be used together. It may call for a different antibiotic, dose adjustment, monitoring or altered administration times.
Patients should not stop an established medicine merely because it appears on an online interaction list.
Why kidney function matters
The kidneys remove a substantial portion of levofloxacin from the body. When kidney function is reduced, the medicine may remain in the bloodstream longer.
This may increase exposure and raise the chance of adverse reactions unless the dosing schedule is changed.
A clinician may use blood-test results and an estimated creatinine-clearance measurement to select a schedule. The patient’s age, weight, sex and serum creatinine may be part of that calculation.
The correct renal adjustment cannot be determined safely from a product page alone. Patients with known kidney problems, dialysis, recent dehydration or a history of abnormal renal tests should discuss this before taking the first dose.
Pregnancy and breastfeeding
Anyone who is pregnant, may be pregnant, plans to become pregnant or is breastfeeding should speak with a qualified medical professional.
The decision requires consideration of:
- The seriousness of the infection
- Other antibiotic options
- The stage of pregnancy
- Maternal medical conditions
- Available safety information
- The possibility of medicine exposure through breast milk
- The health and age of the nursing infant
Do not begin or stop a prescribed antibiotic during pregnancy without speaking to the treating clinician.
Untreated bacterial infection can also carry risks, so the decision should be made through individual medical assessment rather than a general warning.
Antibiotic resistance and responsible use
Antimicrobial resistance is a major public-health problem. Bacteria can become less susceptible to medicines, making infections harder to treat.
Responsible antibiotic use includes:
- Taking an antibiotic only for a diagnosed or strongly suspected bacterial infection
- Following the prescribed dose and schedule
- Not sharing tablets
- Not using leftover antibiotics
- Not requesting antibiotics for viral illnesses
- Attending follow-up care when symptoms do not improve
- Completing laboratory testing when ordered
- Returning unused medicine through an approved disposal route where available
Finishing treatment should follow the prescriber’s current directions. A patient should not shorten or lengthen the course independently.
Contact the prescriber when:
- Symptoms worsen
- Symptoms do not improve as expected
- A serious adverse effect develops
- The diagnosis changes
- Culture results show resistance
- Another clinician recommends a different treatment

How to assess an online pharmacy
Before ordering any prescription medicine online, review whether the pharmacy gives clear answers to the following questions.
Does it require a prescription?
A pharmacy should not market levofloxacin as a casual consumer item. Prescription requirements should be stated plainly.
Is qualified support available?
Patients should be able to ask questions about administration, interactions, storage and adverse reactions.
Are the product details complete?
The listing should identify the active ingredient, strength, dosage form, pack size and relevant manufacturer or supplier information.
Are policies visible?
Look for accessible privacy, shipping, return, refund and prescription policies.
Does the website avoid miracle claims?
No seller should promise that levofloxacin will cure every infection or work without a medical diagnosis.
Are prices transparent?
The website should state whether the listed amount is per tablet, per pack or an estimated effective rate. Shipping and other fees should be shown before payment.
Does it protect personal information?
Medical, identity and payment data should be transmitted and stored through appropriate security controls.
Read the suggested MyRxBox consumer guide:
Levofloxacin storage information
Store the tablets according to the package instructions supplied with the medicine.
General points include:
- Keep tablets in their original packaging.
- Protect them from excess moisture and heat.
- Keep them away from children and pets.
- Do not use tablets after the expiry date.
- Do not take tablets that are damaged, discolored or stored incorrectly.
- Do not transfer them into an unlabeled container.
- Do not share them with another person.
Medicine should not usually be flushed down a toilet or thrown loose into household waste. Ask a pharmacist about a local medicine take-back service or approved disposal method.
Storage requirements can differ by formulation and manufacturer, so the package leaflet should be followed.
When to seek urgent medical help
Obtain urgent medical assessment for symptoms such as:
- Difficulty breathing or swallowing
- Swelling of the face, tongue or throat
- Fainting or a severe irregular heartbeat
- Sudden severe chest, back or abdominal pain
- Seizures
- Severe confusion or hallucinations
- Suicidal thoughts
- Marked muscle weakness
- New numbness, burning or tingling
- Tendon pain or a sudden snapping sensation
- Severe blistering or peeling rash
- Bloody or persistent diarrhea
- Yellow skin or eyes
- Severe low-blood-sugar symptoms
- Loss of consciousness
This is not a complete list of possible emergencies. When symptoms appear severe or rapidly worsen, contact emergency services.
Frequently asked questions
Is Levofloxacin 500 mg a strong antibiotic?
Levofloxacin is a broad-spectrum fluoroquinolone antibiotic with activity against a range of susceptible bacteria. Calling it “strong” can be misleading because antibiotic selection is not based simply on strength.
The best antibiotic is one that is appropriate for the infection, likely to work against the organism and reasonably safe for the patient.
Can I take Levofloxacin 500 mg for a urinary tract infection?
Doctors may prescribe levofloxacin for certain complicated urinary tract infections or kidney infections. It may not be the preferred treatment for every UTI.
A urine test or culture may be required, especially with recurrent infection, fever, pregnancy, kidney disease, treatment failure or suspected resistance.
Can Levofloxacin treat a cough?
A cough alone is not a reason to take levofloxacin. Cough can result from viral infection, asthma, allergy, reflux, pneumonia or many other causes.
A clinician must decide whether a bacterial respiratory infection is present and whether levofloxacin is appropriate.
Can Levofloxacin treat a cold or flu?
No. Colds and influenza are caused by viruses. Levofloxacin acts against susceptible bacteria and does not treat viral infections.
Is Levofloxacin the same as Levoflox 500?
Levofloxacin is the generic active ingredient. Levoflox 500 is a brand or product name used for a tablet containing 500 mg of levofloxacin.
Inactive ingredients, packaging and manufacturer details may differ between products.
How quickly does Levofloxacin work?
The medicine begins acting against susceptible bacteria after it reaches an effective concentration, but the time until symptoms improve depends on the infection and the patient.
Lack of improvement, worsening fever or new symptoms should be reported to the prescriber.
Can I stop taking it when I feel better?
Do not change the course without medical instructions. Feeling better does not necessarily mean that the infection has been fully treated.
At the same time, a serious adverse reaction may require stopping the medicine and obtaining immediate professional advice. Follow the prescription instructions and contact the prescriber when uncertain.
Can I drink alcohol while taking Levofloxacin?
Alcohol may worsen dizziness or other nervous-system effects. It can also make it harder to judge whether symptoms come from the infection, the medicine or alcohol.
Ask the prescribing clinician or pharmacist about alcohol based on your health and medicines.
Can I exercise while taking Levofloxacin?
Because levofloxacin is associated with tendon injury, patients should discuss strenuous exercise and existing tendon problems with their clinician.
Stop activity and seek medical advice when tendon pain, swelling or weakness develops.
What is the listed Levofloxacin 500 mg price?
The supplied MyRxBox listing states an effective price of $0.94 per pill. The final total depends on pack choice and checkout terms.
Check the live page before ordering:
Levofloxacin 500 mg Levoflox Tablets
Do I need a prescription to order Levofloxacin online?
Levofloxacin is a prescription medicine. Applicable prescription and dispensing rules depend on the patient’s country and the pharmacy’s jurisdiction.
A lawful seller should not encourage patients to bypass required medical review.
Is the 500 mg dose suitable for everyone?
No. The correct dose depends on the infection, kidney function, age, other medicines and medical history. Some patients need another strength, another interval or a different antibiotic.
Can Levofloxacin be used for tooth infections?
Dental pain may come from decay, inflammation, an abscess or another condition that needs dental treatment. Levofloxacin is not a routine self-treatment for tooth pain.
A dentist or other qualified prescriber should diagnose the problem and choose the treatment.
Can I use leftover Levofloxacin from an earlier prescription?
No. A new illness may have a different cause, and stored tablets may be expired or may not provide the correct course.
Using leftovers can delay diagnosis, cause adverse effects and contribute to resistance.
What should I tell my prescriber before treatment?
Mention all health conditions, allergies, previous quinolone reactions, pregnancy or breastfeeding, kidney function, heart problems, diabetes, neurological disorders, tendon problems and all medicines or supplements.
