Pefloxacin
About Pefloxacin
Pefloxacin is a prescription oral antibiotic used to treat a wide range of bacterial infections. It is clinically prescribed to resolve serious conditions such as urinary tract infections, respiratory tract infections, and infections of the bones and joints. By targeting and eliminating the bacteria responsible for these illnesses, this medicine helps restore your health and prevent the infection from spreading.
To ensure the medication works effectively, you must take Pefloxacin at regular, evenly spaced intervals exactly as prescribed by your doctor. The tablets should be swallowed whole with a full glass of water, and they can be taken with or without food. Drinking plenty of fluids and getting adequate rest during your recovery will further support the healing process.
While taking Pefloxacin, some people may experience mild side effects, such as a temporary upset stomach, nausea, or a mild headache. However, you should contact your doctor or pharmacist immediately if you experience severe symptoms like sudden joint pain, nerve tingling, or an unexpected skin rash.
Before starting this medicine, talk to your doctor if you have a history of kidney disease, epilepsy, or nerve problems. Do not take this if you have previously had tendon damage caused by similar antibiotics, or if you are allergic to this class of medication.
This medicine can interact with certain other substances, such as mineral supplements, blood thinners, and caffeine, which can reduce its effectiveness or increase side effects. It is also recommended to avoid alcohol and smoking during treatment to help your body recover more efficiently. Pregnant women, breastfeeding mothers, and elderly individuals should always consult their doctor to ensure this medication is safe for their specific needs.

Drug Interactions
- Antacids and mineral supplements (e.g., Magnesium hydroxide, Aluminium hydroxide, Iron, Zinc): These medicines can bind to Pefloxacin in your gut, stopping it from being absorbed. Take these supplements at least 2 hours before or 6 hours after your antibiotic.
- Blood thinners (e.g., Warfarin): Combining this medicine with blood thinners can increase the risk of bleeding.
- Nonsteroidal anti-inflammatory drugs (e.g., Ibuprofen, Naproxen): Taking pain relievers alongside this antibiotic may increase the risk of central nervous system stimulation and seizures.

Habit Forming
Diet & Lifestyle Advise
- Avoid dairy and calcium-rich foods close to your dose: Do not consume milk, cheese, yoghurt, or calcium-fortified juices at the same time as Pefloxacin. Calcium can bind to the medicine in your stomach and significantly decrease its absorption. Take your dose at least 2 hours before or 4 to 6 hours after eating these foods.
- Stay well hydrated: Drink plenty of water throughout the day while taking this medicine. Proper hydration helps flush the medicine through your kidneys and prevents crystals from forming in your urine.
- Protect your skin from the sun: This medicine makes your skin highly sensitive to sunlight and UV rays. Wear protective clothing, use a high-SPF sunscreen, and avoid direct sun exposure or tanning beds during your treatment.
- Limit your caffeine intake: This antibiotic can slow down the rate at which your body processes caffeine. To avoid feeling jittery, anxious, or experiencing a rapid heartbeat, limit your intake of coffee, tea, and energy drinks.
Special Advise
Tendon damage can occur after a few months of starting Pefloxacin treatment. The onset of symptoms and signs of the side effects may be delayed several months after stopping treatment. At the first sign of tendinitis (like painful swelling or inflammation), immediately stop taking Pefloxacin. The affected limbs should be appropriately treated (e.g., immobilization).
Patients Concern
Disease/Condition Glossary
A bacterial infection is a condition in which harmful bacteria enter, multiply and infect our bodies. It can target any body part and multiple very quickly. When you get infected with bacteria, you can experience generalized symptoms like fevers, chills and fatigue. Bacteria are of various forms comprising, commonly spherical, rod, and spiral-shaped. Bacterial infections vary from minor illnesses like sore throat and ear infections to severe brain infections like meningitis and encephalitis. A few harmful bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli. Anyone can become infected with a bacterial infection. People with weak immune systems or taking immunosuppressive medicine can make them more prone to bacterial infection.
FAQs
No. Avoid taking Pefloxacin together with milk, yoghurt, or other dairy products because the calcium can reduce how much of the medicine your body absorbs, making it less effective. Take Pefloxacin at least 2 hours before or 4–6 hours after consuming dairy products. If you need help planning your doses, speak with your doctor or pharmacist.
Pain, swelling, or tenderness in a joint or tendon—especially around the Achilles tendon—may be a sign of tendon inflammation or rupture, a rare but serious side effect of Pefloxacin. Stop taking the medicine, avoid exercising or putting weight on the affected area, and contact your doctor immediately. Your doctor may recommend an alternative antibiotic if needed.
Diarrhoea can occur while taking antibiotics because they affect both harmful and beneficial bacteria in the gut. However, if you develop severe, persistent, watery, or bloody diarrhoea, contact your doctor immediately, as this may indicate a serious bowel infection. Do not take over-the-counter anti-diarrhoeal medicines unless your doctor advises you to.
This medicine can make your skin highly sensitive to sunlight and UV rays, a condition called photosensitivity. This means you could get a severe sunburn, skin rash, or blisters much faster than usual. When outdoors, wear long sleeves, a hat, and use a high-SPF sunscreen. Talk to your doctor or pharmacist if you develop a severe skin reaction.
You should limit your caffeine intake while taking Pefloxacin. This medicine slows down how quickly your body breaks down caffeine, which can make you feel jittery, anxious, or cause your heart to beat unusually fast. If you experience these symptoms, try switching to decaffeinated beverages. Talk to your doctor or pharmacist if you have concerns.
Pefloxacin is generally not recommended during pregnancy or while breastfeeding unless your doctor determines that the benefits outweigh the potential risks. Concerns about its effects on developing joints and bones are based mainly on animal studies, and the risk in humans has not been clearly established. If you are pregnant, planning to become pregnant, or breastfeeding, discuss your treatment options with your doctor before taking this medicine.
No, you must finish the entire course of Pefloxacin prescribed by your doctor, even if you feel completely better after a few days. Stopping the antibiotic too early can allow the strongest bacteria to survive, which can cause the infection to return and make the bacteria resistant to future treatments. Talk to your doctor or pharmacist if you feel the medication is not agreeing with you.
You should check with your doctor before taking nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen while taking Pefloxacin. Taking these medications together can sometimes increase the risk of central nervous system side effects, including seizures. Talk to your doctor or pharmacist for safe pain relief recommendations.
