Need information on cephalexin? This antibiotic treats various bacterial infections, including skin, ear, and respiratory tract infections. Your doctor prescribes the dosage based on your specific needs and the type of infection. Always follow their instructions carefully.
Typical cephalexin courses range from 7 to 14 days. Never stop taking it prematurely, even if you feel better, as this can lead to recurring infections or antibiotic resistance. Common side effects include diarrhea, nausea, and stomach upset; however, severe allergic reactions are possible. Seek immediate medical attention if you experience difficulty breathing, hives, or swelling.
Cephalexin interacts with certain medications, including anticoagulants and antacids. Inform your doctor and pharmacist about all medications you are taking to avoid potential complications. Proper hydration is crucial throughout treatment. Drink plenty of water to support your body’s natural processes and aid in eliminating the medication.
Remember: This information is for general knowledge and doesn’t replace professional medical advice. Always consult your doctor or pharmacist before starting any medication, including cephalexin. They can assess your condition and provide personalized recommendations for dosage, duration, and potential side effects.
Prescription Antibiotic Cephalexin
Cephalexin treats bacterial infections. Take it exactly as prescribed; don’t adjust the dosage yourself.
Dosage: Your doctor determines the correct dose based on your infection’s severity and your health. Typical adult doses range from 250mg to 500mg, four times daily. Children’s doses vary significantly. Always follow your prescription instructions meticulously.
Administration: Swallow capsules whole with water. Take it with food if it upsets your stomach. Maintain consistent timing between doses for optimal effectiveness.
Duration: Finish the entire course of antibiotics, even if you feel better sooner. Stopping early may lead to recurring infection or antibiotic resistance. Your doctor will specify the treatment length.
Possible Side Effects: Common side effects include diarrhea, nausea, and vomiting. Less frequent but potentially serious side effects include allergic reactions (rash, hives, difficulty breathing) and Clostridium difficile-associated diarrhea. Contact your doctor immediately if you experience any concerning symptoms.
Interactions: Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. Cephalexin may interact with certain medications.
Allergies: Tell your doctor if you have any known drug allergies, especially penicillin allergies, as cross-reactivity is possible.
Pregnancy and Breastfeeding: Discuss cephalexin use with your doctor if you are pregnant, breastfeeding, or planning to become pregnant. Its safety during pregnancy and breastfeeding requires careful evaluation.
Missed Dose: Take the missed dose as soon as you remember, unless it’s almost time for your next dose. Never double up on doses.
Storage: Store cephalexin at room temperature, away from moisture and light.

What is Cephalexin and How Does it Work?
Cephalexin is a first-generation cephalosporin antibiotic. It fights bacterial infections by interfering with the bacteria’s ability to build cell walls. Specifically, it inhibits the formation of peptidoglycans, essential components of bacterial cell walls.
This disruption leads to bacterial cell death. Cephalexin is effective against a broad spectrum of Gram-positive and some Gram-negative bacteria, making it useful for treating various infections.
Your doctor will prescribe cephalexin for specific bacterial infections like skin infections, ear infections, and urinary tract infections. The dosage and duration of treatment depend on the severity and type of infection. Always follow your doctor’s instructions carefully.
Common side effects include diarrhea, nausea, and vomiting. Serious allergic reactions are rare but possible. Seek immediate medical attention if you experience symptoms like hives, swelling, or difficulty breathing. Inform your doctor about all medications you are currently taking to avoid potential drug interactions.
Common Uses and Dosages of Cephalexin
Cephalexin effectively treats various bacterial infections. Doctors commonly prescribe it for skin infections like impetigo and cellulitis. Dosage typically ranges from 250mg to 500mg, administered orally every six to eight hours. The exact amount and frequency depend on the severity of the infection and the patient’s weight and overall health.
Ear infections, particularly otitis media, also respond well to cephalexin. Children often receive doses calculated based on their weight, usually 25-50 mg/kg/day divided into two to four doses. Always follow your doctor’s instructions precisely.
For urinary tract infections (UTIs), cephalexin is a frequent choice. A common adult dosage is 250mg or 500mg four times daily. The duration of treatment typically varies between seven and ten days, depending on the individual’s response to the medication.
Respiratory infections, such as strep throat and pneumonia, can be treated with cephalexin; however, other antibiotics are often preferred. Your physician will determine the most appropriate antibiotic based on the specific infection and the results of any lab tests conducted.
Remember: This information provides general guidance only. Always consult your physician or pharmacist for personalized advice on dosage and treatment duration. They will consider your specific medical history and current health status to tailor the treatment plan to your needs. Never adjust your dosage without consulting a medical professional.
Potential Side Effects and Precautions
Cephalexin, while generally safe, can cause side effects. Common ones include diarrhea, nausea, and vomiting. These usually are mild and resolve without treatment. However, persistent or severe diarrhea might indicate Clostridium difficile infection, requiring immediate medical attention. Report any significant digestive upset to your doctor.
Allergic Reactions
Serious allergic reactions, though rare, are possible. These can manifest as hives, swelling (especially of the face, lips, or tongue), difficulty breathing, or dizziness. If you experience any of these, seek immediate medical help; this is a medical emergency. Prior allergies to penicillin or other cephalosporin antibiotics increase your risk.
Other Potential Side Effects
Less common side effects include abdominal pain, headache, fatigue, and vaginal yeast infections. Long-term use can disrupt gut flora, potentially leading to secondary infections. Inform your doctor about any existing health conditions, including kidney or liver problems, before starting cephalexin. Pregnancy and breastfeeding should also be discussed with your doctor before starting any antibiotic treatment. Always follow your prescribed dosage and duration precisely. Do not stop taking cephalexin prematurely, even if you feel better.
Medication Interactions
Cephalexin may interact with certain medications. Always inform your doctor or pharmacist of all medications, supplements, and herbal remedies you are taking to avoid potential interactions. This includes over-the-counter drugs. Proper communication is vital for safe medication use.
Alternatives and When to Seek Medical Attention
If cephalexin isn’t suitable or effective, your doctor might suggest alternative antibiotics like amoxicillin, erythromycin, or clindamycin, depending on the infection. They’ll consider factors like your allergies and the type of bacteria causing the infection.
Non-antibiotic treatments may also be appropriate for certain infections. These could include:
- Pain relievers like ibuprofen or acetaminophen to manage discomfort.
- Topical creams or ointments for skin infections.
- Lifestyle changes, such as increased fluid intake for urinary tract infections.
Always discuss alternative treatments with your doctor; self-treating can be harmful.
Seek immediate medical attention if you experience:
- Severe allergic reactions, including difficulty breathing, swelling of the face or throat, or hives.
- Persistent or worsening symptoms after several days of taking cephalexin.
- New or worsening symptoms, such as fever, chills, or severe abdominal pain.
- Diarrhea that is severe, bloody, or lasts for more than a few days (this could indicate Clostridium difficile infection).
Your doctor can assess your condition and determine the best course of action. Don’t hesitate to contact them with any concerns.
