FLOXIN 500

# FLUCLOXACILLIN 500 MG ## SHORT DESCRIPTION **Flucloxacillin 500 mg** is a **penicillin-type antibiotic** belonging to the beta-lactam group. It is mainly used to treat bacterial infections caused by susceptible **penicillinase-producing staphylococci**, including certain infections of the skin, soft tissues, bones, joints, and respiratory tract. Flucloxacillin is **not effective against viral infections** such as the common cold or flu. It should be used only when prescribed or recommended by a qualified healthcare professional. --- ## KEY BENEFITS * Treats susceptible **bacterial infections**. * Particularly useful against certain **Staphylococcus** infections that produce penicillinase. * May be used for infections involving the **skin and soft tissues**. * May be prescribed for certain **bone and joint infections**. * Can be used for selected respiratory and other susceptible bacterial infections. * Helps eliminate susceptible bacteria and control infection when used appropriately. --- ## USES / INDICATIONS Flucloxacillin 500 mg may be prescribed for susceptible bacterial infections such as: * **Skin and soft-tissue infections** * Cellulitis * Abscesses, when antibiotic treatment is indicated * Wound infections * Infected burns * Certain **bone and joint infections** * Certain respiratory tract infections * Certain bloodstream or systemic infections caused by susceptible organisms * Other infections caused by susceptible penicillinase-producing staphylococci The exact indication should be determined by a healthcare professional based on the infection and bacterial susceptibility. --- ## HOW IT WORKS Flucloxacillin is a **beta-lactam antibiotic**. It binds to bacterial **penicillin-binding proteins (PBPs)**, which are involved in constructing the bacterial cell wall. This interferes with bacterial cell-wall formation, eventually causing susceptible bacteria to rupture and die. **Flucloxacillin → binds bacterial PBPs → inhibits cell-wall synthesis → bacterial death.** Flucloxacillin is relatively resistant to destruction by certain bacterial beta-lactamases (penicillinases), making it useful against susceptible penicillinase-producing staphylococci. --- ## DOSAGE & ADMINISTRATION Take Flucloxacillin exactly as prescribed. ### Typical Adult Use For many adult infections, **500 mg four times daily** is a commonly used regimen, but the exact dose depends on: * Type and severity of infection * Patient's age * Kidney and liver function * Clinical response * Local prescribing guidelines **Do not use this example as a substitute for your prescribed regimen.** ### How to Take * Flucloxacillin is generally best taken on an **empty stomach**. * Take it approximately **30–60 minutes before meals** or at least 2 hours after food, according to the product instructions. * Swallow capsules with a full glass of water. * Space doses evenly throughout the day. * Complete the prescribed course unless your healthcare professional tells you otherwise. ### Missed Dose Take the missed dose when remembered unless it is nearly time for your next dose. **Do not take two doses together.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Nausea * Vomiting * Diarrhea * Indigestion * Abdominal discomfort * Skin rash ### Serious Side Effects Seek urgent medical attention if you develop: * Difficulty breathing * Swelling of the face, lips, tongue, or throat * Severe allergic reaction * Severe or persistent diarrhea * Bloody diarrhea * Yellowing of the skin or eyes * Dark urine * Severe skin reactions * Unusual bruising or bleeding Antibiotic-associated **Clostridioides difficile** diarrhea can occur during or after antibiotic treatment and may require medical treatment. --- ## PRECAUTIONS & WARNINGS ### Penicillin Allergy Do not take flucloxacillin if you have previously experienced a serious allergic reaction to: * Flucloxacillin * Penicillins * Other beta-lactam antibiotics, where cross-reactivity is a concern Tell your healthcare professional about any previous antibiotic allergy. ### Liver Problems Flucloxacillin can rarely cause **liver injury or cholestatic jaundice**. Tell your healthcare professional if you have a history of liver disease or previous liver problems associated with penicillin antibiotics. Seek medical attention if you develop yellow skin/eyes, dark urine, or persistent itching. ### Kidney Disease Dose or monitoring considerations may be necessary in significant kidney impairment. ### Antibiotic-Associated Diarrhea Persistent or severe diarrhea during or after treatment may indicate antibiotic-associated colitis. Do not self-treat severe antibiotic-related diarrhea with antidiarrheal medicines without medical advice. ### Prolonged Treatment Longer courses may require monitoring of liver, kidney, or blood function, particularly in patients with underlying medical conditions. ### Infectious Mononucleosis Patients with infectious mononucleosis may have a higher likelihood of developing a rash when treated with certain penicillin antibiotics. ### Complete the Course Take the antibiotic for the duration prescribed. Stopping treatment too early may allow the infection to persist and may contribute to antibiotic resistance. --- ## DRUG INTERACTIONS Tell your healthcare professional about all medicines and supplements you take. ### Warfarin and Other Anticoagulants Antibiotic treatment can sometimes affect anticoagulant control. Patients taking **warfarin** may require additional monitoring of clotting parameters. ### Methotrexate Penicillin antibiotics may potentially affect methotrexate elimination and increase toxicity risk. Medical supervision is important when these medicines are combined. ### Probenecid Probenecid can reduce renal elimination of penicillins and may increase flucloxacillin concentrations. ### Other Antibiotics Combining antibiotics should only be done when clinically appropriate and prescribed by a healthcare professional. ### Oral Contraceptives Some people are concerned about antibiotics reducing the effectiveness of hormonal contraception. Flucloxacillin does **not generally reduce contraceptive effectiveness directly**, but vomiting or severe diarrhea can interfere with oral contraceptive absorption. Follow contraceptive guidance provided by your healthcare professional. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep capsules in their original packaging. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach of children. * Do not use after the expiry date. * If using a liquid formulation, follow the product-specific storage and discard instructions. --- ## PRESCRIPTION STATUS **Prescription medicine.** Flucloxacillin 500 mg should be used only under the direction of a qualified healthcare professional. Prescription requirements may vary by country. --- ## GENUINE MEDICINE ASSURANCE When purchasing **Flucloxacillin 500 mg**, obtain it from a **licensed pharmacy or authorized medicine supplier**.
