What is Cephalexin and How Does it Work?

Cephalexin is an antibiotic in the cephalosporin family. It fights bacterial infections by preventing bacteria from building cell walls, effectively killing them. This mechanism differs from other antibiotic classes, making it effective against bacteria resistant to different drug types.

Specifically, cephalexin disrupts the synthesis of peptidoglycans, crucial components of bacterial cell walls. This leads to bacterial cell lysis and death.

• Cephalexin treats a wide range of infections, including:
• Skin infections
• Ear infections
• Respiratory tract infections
• Bone and joint infections
• Urinary tract infections

Your doctor will determine the appropriate dosage and duration of treatment based on your specific infection and health status. Always follow their prescribed instructions carefully.

Remember to complete the entire course of medication, even if you start feeling better. Stopping early can lead to recurring infections and antibiotic resistance.

1. Possible side effects include:
2. Diarrhea
3. Nausea
4. Vomiting
5. Rash
6. Yeast infections

If you experience any severe or unusual side effects, contact your doctor immediately. Inform your physician about all medications you are currently taking, including over-the-counter drugs and supplements, to avoid potential interactions.

Common Uses of Cephalexin: Treating Bacterial Infections

Cephalexin effectively combats various bacterial infections. Doctors frequently prescribe it for skin infections like impetigo and cellulitis. These conditions often present with redness, swelling, and pain.

Respiratory tract infections, such as bronchitis and pneumonia (certain types), also respond well to cephalexin treatment. However, it’s crucial to note that cephalexin’s efficacy depends on the specific bacteria causing the infection; your doctor will determine if it’s the right choice.

Ear infections (otitis media) in children are another common application. Cephalexin can reduce inflammation and alleviate symptoms like pain and fever, though the specific dosage will vary depending on the patient’s age and weight.

Urinary tract infections (UTIs) are a frequent reason for cephalexin prescription. This antibiotic targets common UTI-causing bacteria. However, remember that resistance is a concern, and proper diagnostics are always necessary.

Always follow your doctor’s instructions regarding dosage and treatment duration. Do not stop taking cephalexin prematurely, even if you feel better, as this can lead to recurrence or development of resistant bacteria.

Cephalexin treats infections caused by susceptible bacteria. Its use against infections caused by viruses is ineffective. Consult your doctor for diagnosis and appropriate treatment.

Dosage and Administration: Following Your Doctor’s Instructions

Always take cephalexin exactly as prescribed by your doctor. The dosage depends on your specific infection, weight, and overall health. Never adjust your dose without consulting your physician.

Typical Dosage Guidelines

Common dosages range from 250mg to 1000mg, taken every 6 to 12 hours. Your doctor will determine the frequency and duration of treatment. Here are some examples, but remember these are just illustrations, and your doctor will tailor your treatment plan:

• Adults with mild infections: 250mg every 6 hours
• Adults with moderate to severe infections: 500mg every 12 hours or 250mg every 6 hours
• Children: Dosage is calculated based on weight and the type of infection. Your doctor will provide precise instructions.

Important Administration Tips

1. Take cephalexin with a full glass of water. This helps to prevent stomach upset.
2. Take the medication at evenly spaced intervals throughout the day, as directed by your doctor. Setting reminders can help.
3. Do not crush, chew, or break the capsules or tablets. Swallow them whole.
4. Complete the full course of medication, even if you start feeling better. Stopping early can lead to recurring infection.
5. Store cephalexin at room temperature, away from moisture and direct sunlight.
6. Inform your doctor of any other medications you are taking, including over-the-counter drugs and herbal supplements. Potential drug interactions need to be addressed.

Missed Dose

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 to make up for a missed one. Contact your doctor if you have questions about missed doses or any other concerns.

Potential Side Effects of Cephalexin: What to Watch For

Cephalexin, while generally safe, can cause side effects. Monitor yourself for these common issues.

• Gastrointestinal Upset: Diarrhea, nausea, and vomiting are frequently reported. Drink plenty of fluids to help mitigate these.
• Allergic Reactions: Skin rashes, itching, hives, or swelling (especially of the face, lips, or tongue) require immediate medical attention. This is a serious reaction and needs prompt treatment.
• Yeast Infections: Cephalexin can disrupt the natural balance of your gut flora, leading to yeast infections (thrush). Watch for oral thrush (white patches in the mouth) or vaginal yeast infections.

Less common, but still possible side effects include:

• Headache
• Dizziness
• Fatigue
• Changes in taste

Rare but serious side effects necessitate immediate medical attention:

1. Difficulty breathing
2. Chest pain
3. Severe stomach pain
4. Jaundice (yellowing of the skin or eyes)
5. Unusual bleeding or bruising

This information isn’t exhaustive, and individual reactions vary. Always consult your doctor or pharmacist if you experience any concerning symptoms while taking cephalexin. They can provide personalized advice and address any specific concerns you may have.

Drug Interactions: Important Considerations

Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies. This includes vitamins and even seemingly innocuous products like St. John’s Wort. Cephalexin can interact with several substances, potentially altering its effectiveness or causing side effects.

Antacids and Cephalexin

Taking cephalexin with antacids containing aluminum or magnesium can reduce its absorption. Separate the administration of these medications by at least two hours for optimal cephalexin effectiveness. Consult your pharmacist for advice if you’re unsure about specific antacid formulations.

Warfarin Interaction

Cephalexin may interact with the anticoagulant warfarin, potentially increasing the risk of bleeding. Regular monitoring of your INR (International Normalized Ratio) is vital if you’re taking both medications. Your doctor will adjust your warfarin dose accordingly.

Probenecid and Cephalexin

Probenecid, a medication used to treat gout, can increase the blood levels of cephalexin. This may lead to an increased risk of side effects. Your physician should carefully consider the potential risks and benefits if prescribing both drugs concurrently.

Other Potential Interactions

While less common, cephalexin may also interact with methotrexate (a chemotherapy drug) and oral contraceptives. Discuss these interactions with your healthcare provider to ensure safe and effective medication use. They can help assess the risks and benefits for your specific situation.

Medication	Potential Interaction	Recommendation
Antacids (aluminum/magnesium)	Reduced cephalexin absorption	Separate administration by at least 2 hours
Warfarin	Increased bleeding risk	Regular INR monitoring
