Common Uses

Cephalexin is a cephalosporin antibiotic that inhibits bacterial cell wall synthesis, making it effective against various infections. It is resistant to penicillinase enzymes produced by gram-positive bacteria but susceptible to beta-lactamase enzymes from certain gram-negative strains. This antibiotic targets a broad spectrum of bacteria, including Staphylococcus, Streptococcus, Corynebacterium diphtheriae, Clostridium, Actinomyces israelii, and Bacillus anthracis. Additionally, it is active against gram-negative organisms such as Escherichia coli, Klebsiella, Proteus mirabilis, Neisseria gonorrhoeae, Neisseria meningitidis, Shigella, and Salmonella. Cephalexin is widely prescribed for its efficacy in treating bacterial infections across diverse clinical settings.

Cephalexin is commonly prescribed to address middle ear infections, tonsillitis, throat infections, laryngitis, bronchitis, pneumonia, urinary tract infections, skin infections, and bone infections. This antibiotic is effective in treating bacterial infections across various parts of the body, making it a versatile option for healthcare providers. It is particularly useful for respiratory and urinary tract infections, as well as skin and bone-related conditions. Always consult a doctor for proper diagnosis and treatment.

Dosage and Directions

For treating bacterial infections, adults typically take 1 to 4 grams of Cephalexin per day, divided into doses administered every 6 to 12 hours based on the specific infection. This antibiotic dosage ensures effective treatment while minimizing side effects, making it a widely prescribed option for various bacterial conditions. Always follow your healthcare provider's instructions for optimal results and safety.

Precautions

• Notify your healthcare provider about any known medication allergies, particularly to penicillin antibiotics. This information is crucial for safe and effective treatment.
• Consult your physician if you have kidney disease, liver issues, gastrointestinal conditions such as colitis, or diabetes before initiating Cephalexin treatment for bacterial infections. Ensure your healthcare provider is informed of these medical conditions to avoid potential complications or adverse effects. Proper disclosure of your health history is crucial for safe and effective use of this antibiotic.

Contraindications

Avoid using Cephalexin if you have a known allergy to this medication or other cephalosporin antibiotics like Ceclor, Duricef, Omnicef, Spectracef, Suprax, Cefzil, Fortaz, or Ceftin. Use caution when taking Cephalexin if you have kidney disease, pseudomembranous colitis, are pregnant, breastfeeding, or administering it to infants under six months old. Always consult a healthcare provider for personalized medical advice and proper dosage.

Possible Side Effects

Common side effects may involve allergic reactions like hives, rash, or swelling of the face and tongue, which require medical attention for allergic response management. Serious symptoms demanding urgent care include seizures, high fever, persistent sore throat, severe skin reactions like blistering or peeling, and jaundice signaled by pale or yellow skin. Other critical signs are dark urine, hallucinations, confusion, muscle weakness, unusual bruising or bleeding, reduced urination, or extreme agitation, all of which necessitate emergency medical intervention. Monitoring for these adverse effects is essential for patient safety and effective treatment outcomes. Prompt recognition and response to such symptoms can prevent complications and ensure proper healthcare management.

Drug Interactions

• Inform your physician about all current medications, particularly live vaccines and probenecid, to ensure safe medication management and avoid potential drug interactions. This step is crucial for optimizing patient health and minimizing adverse effects.
• Cephalexin can potentially decrease the efficacy of combined oral contraceptives, impacting birth control effectiveness. Patients on antibiotics like cephalexin should consider alternative contraceptive methods to ensure optimal protection. Managing interactions between antibiotics and birth control is crucial for maintaining contraceptive reliability. Always consult healthcare providers for personalized advice on medication and contraception.
• Certain substances may trigger inaccurate readings in diabetic urine glucose tests, leading to false positives.
• This substance may amplify the efficacy of indirect anticoagulants, phenylbutazone, and furosemide, enhancing their therapeutic outcomes. Such interactions are crucial for optimizing drug regimens and ensuring patient safety in clinical practice. Monitoring these effects is essential for effective treatment and improved health results.
• Salicylates and indomethacin can reduce the renal clearance of Cephalexin, leading to elevated blood concentrations of the antibiotic. This interaction highlights the importance of monitoring kidney function and drug levels when combining these medications. Understanding these pharmacokinetic effects is crucial for optimizing antibiotic therapy and preventing potential side effects.

Missed Dose

If you forget to take a dose, take it immediately upon remembering; however, if it's almost time for your next scheduled dose, skip the missed one and resume your normal medication routine. Avoid taking double doses to prevent potential side effects. Stick to your prescribed schedule for optimal health management and effective treatment outcomes.

Overdose

If you encounter ongoing or intense nausea, vomiting, abdominal pain, diarrhea, or notice blood in your urine, consult a healthcare provider immediately. Prompt medical consultation is crucial for addressing severe gastrointestinal or urinary symptoms effectively. Early intervention can help manage discomfort and prevent potential complications associated with these health issues. Always prioritize professional medical advice for persistent or alarming symptoms to ensure timely and appropriate care.

Storage

Store Cephalexin at a stable room temperature of 59 to 77°F (15-25°C), ensuring it is protected from moisture, light, children, and pets. Always check the expiration date and avoid using the antibiotic after it has expired to maintain its effectiveness and safety. Proper storage of Cephalexin capsules ensures optimal potency and reduces the risk of improper use. Keep medications secure and follow these guidelines to safeguard your health.
