What is Keflex and How Does it Work?

Keflex, or Cephalexin, is a cephalosporin antibiotic. It combats bacterial infections by interfering with the bacteria’s ability to build cell walls. Specifically, it inhibits the synthesis of peptidoglycans, crucial components of bacterial cell walls.

This disruption leads to bacterial cell death. Keflex targets a wide range of gram-positive bacteria, including those responsible for common infections like skin infections, ear infections, and urinary tract infections. It’s less effective against gram-negative bacteria.

Bacterial Type	Effectiveness
Gram-positive (e.g., Staphylococcus aureus)	Generally High
Gram-negative (e.g., Escherichia coli)	Variable; often less effective

Your doctor will prescribe the correct dosage based on your specific infection and health factors. Always follow their instructions precisely regarding dosage, frequency, and duration of treatment. Complete the entire course, even if you feel better sooner, to prevent recurrence of the infection. Possible side effects include diarrhea, nausea, and stomach upset. Inform your doctor of any allergies or pre-existing conditions before starting treatment.

Common Infections Treated with Keflex

Keflex, or cephalexin, effectively combats various bacterial infections. It’s frequently prescribed for skin infections like impetigo and cellulitis, characterized by redness, swelling, and pus. These infections often respond well to Keflex’s antibiotic action.

Respiratory Tract Infections

Keflex also treats certain respiratory infections, including bronchitis and pneumonia caused by susceptible bacteria. However, it’s crucial to note that its effectiveness against these varies depending on the specific bacteria involved. Your doctor will determine if Keflex is the right choice based on your symptoms and test results. Always follow prescribed dosages and complete the entire course of treatment.

Other Infections

Beyond skin and respiratory issues, Keflex is sometimes used to treat ear infections (otitis media), urinary tract infections (UTIs), and bone infections (osteomyelitis). However, the choice of antibiotic depends on the specific infection and its severity. Your doctor will assess your condition and choose the most appropriate treatment.

Potential Side Effects and Allergic Reactions

Keflex, like all antibiotics, can cause side effects. Common reactions include diarrhea, nausea, and vomiting. These usually are mild and resolve without treatment. However, report persistent or severe gastrointestinal upset to your doctor.

Less Common Side Effects

Less frequent side effects involve changes in your blood cell counts, potentially leading to fatigue or bruising. Skin reactions, such as rashes or itching, are also possible. Severe skin reactions, including Stevens-Johnson syndrome, are rare but serious. Seek immediate medical attention if you experience a severe rash, blistering, or peeling skin. Similarly, jaundice (yellowing of the skin or eyes) necessitates immediate medical evaluation.

Allergic Reactions

Allergic reactions to Keflex range from mild hives to life-threatening anaphylaxis. Symptoms of a mild allergic reaction include itching, swelling, and hives. Anaphylaxis presents with difficulty breathing, swelling of the face and throat, and a rapid heartbeat. If you experience any allergic reaction, discontinue Keflex immediately and seek emergency medical care.

Before starting Keflex, inform your doctor of any known drug allergies. This proactive measure helps prevent potential complications.

Dosage and Administration Guidelines

Always follow your doctor’s prescription exactly. Typical Keflex doses vary depending on the infection being treated and the patient’s weight and kidney function. For adults, common dosages range from 250mg to 1000mg, taken every 6 to 12 hours. Children’s dosages are calculated based on weight, typically 25-50 mg per kilogram of body weight per day, divided into two to four doses.

Keflex is usually taken orally with a glass of water. You can take it with or without food, but consistent timing is important for maintaining consistent blood levels of the antibiotic. If gastrointestinal upset occurs, taking it with food may help.

The duration of treatment varies depending on the severity of the infection and your response to the medication. Complete the entire course of antibiotics, even if you start feeling better before the prescription is finished. Stopping early can lead to treatment failure and potential antibiotic resistance.

If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose. Never double up on doses. Immediately contact your doctor if you experience any side effects, such as severe diarrhea, allergic reactions (rash, itching, swelling), or unusual changes in your urination or bowel movements.

Proper storage is crucial. Keep Keflex at room temperature, away from moisture and direct sunlight. Always consult your pharmacist or doctor if you have questions about dosage, administration, or potential interactions with other medications.

Drug Interactions and Precautions

Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies. Keflex can interact with certain medications, potentially altering their effectiveness or increasing the risk of side effects.

Warfarin: Keflex may increase the effects of warfarin (a blood thinner), potentially leading to increased bleeding risk. Close monitoring of your INR (international normalized ratio) is necessary if you’re taking both medications.

Methotrexate: Concurrent use with Keflex might raise the levels of methotrexate in your blood, increasing the chance of methotrexate-related toxicity. Your doctor should carefully monitor your condition.

Oral contraceptives: Keflex may reduce the effectiveness of some oral contraceptives. Consider using alternative birth control methods while taking Keflex.

Antacids: Taking antacids concurrently with Keflex can reduce Keflex absorption. Separate the administration of these medications by at least two hours.

Alcohol: While not a direct drug interaction, excessive alcohol consumption can strain your liver, which is processing the antibiotic. Moderate alcohol use is recommended while on Keflex.

Before starting Keflex, discuss any allergies you have, particularly to penicillin or cephalosporin antibiotics. Report any signs of allergic reaction, such as rash, itching, or difficulty breathing, immediately to your doctor. Kidney or liver problems may require dosage adjustment; your physician will determine the correct dose for your condition.

This information doesn’t encompass every possible interaction or precaution. Consult your doctor or pharmacist for personalized advice and address any concerns you may have.

Keflex vs. Other Antibiotics: Comparing Effectiveness

Cephalexin (Keflex) excels against gram-positive bacteria like Streptococcus and Staphylococcus, commonly causing skin infections and strep throat. However, its efficacy varies depending on the specific bacterial strain and its resistance profile.

Keflex vs. Amoxicillin

Amoxicillin often treats similar infections. Keflex generally shows better results against penicillin-resistant Staphylococcus aureus (MRSA), while amoxicillin might be preferred for certain types of strep infections where Keflex might not be as potent. Always consult a doctor to determine the most suitable antibiotic.

Keflex vs. Augmentin

Augmentin (amoxicillin-clavulanate) combines amoxicillin with clavulanate, broadening its spectrum to include some bacteria resistant to amoxicillin alone. Keflex remains superior for some gram-positive bacteria, but Augmentin’s broader coverage makes it suitable for more complex or mixed infections. Your doctor will consider the specific infection to choose the most suitable antibiotic.

Remember, antibiotic choice depends on individual factors, including infection severity, patient allergies, and bacterial susceptibility testing. This information is for educational purposes and should not replace professional medical advice. Always seek guidance from a healthcare professional before starting or altering any antibiotic treatment.
