What Exactly Is Cephalexin

Cephalexin, also spelled as cefalexin, is a prescription antibiotic that belongs to a class known as cephalosporins. Its sold on the market under the brand names Keflex and Daxbia as a capsule, tablet, and oral suspension. According to, around 10 percent of people who have penicillin allergy will also have cephalexin allergy.

This antibiotic has a high efficacy rate of 90 percent . One great thing about this drug is that it doesnt rapidly degrade in stomach acid. For this reason, more of the drug is available for absorption to achieve its intended effects.

As an antibiotic, cephalexin is used for treating a wide array of infections that involve the skin, bones, ears, respiratory tract, and genitourinary system . When it comes to skin infections, its mainly effective against gram-positive Staphylococcus and Streptococcus bacteria.

Clinical Manifestations Of Inflammation

Cephalexin Capsules 250 mg, 60ct

The cardinal manifestations of inflammation are warmth, erythema, edema, pain and dysfunction . Prolonged inflammation can lead to chronic edema, especially in the lower extremities, and can result in a postcellulitic syndrome. Ancillary systemic signs, such as fever, hypotension and tachycardia, result from cytokine-induced changes in thermoregulation and vascular resistance. The release of cytokines may be mediated by the normal immune cell function or by bacterial toxin stimulation. Out-of-proportion pain results from severe damage of the deep layers of skin produced by bacterial toxins, while bullous lesions are produced by toxin-mediated epidermal cleavage. Skin anesthesia, which may be present during the course of necrotizing fasciitis, occurs secondary to toxin-mediated nerve tissue damage. Also, violaceous lesions result from toxin-mediated lysis of erythrocytes and hemorrhage .

What I did before

A 32 year old woman, otherwise healthy, presented with a spider-bite. On exam, she had a tender abscess on her buttock. It was associated with some surrounding cellulitis but no fever or other systemic features. I recommended incision and drainage, but she wasnt keen on it, so I gave her a 7-day prescription for cephalexin 500 mg po qid.

What changed my practice

The woman returned to the office 1 week later. The abscess had increased in size and another one had appeared on her labia. She was in significant discomfort and reported no improvement with the cephalexin. Incision and drainage of her abscesses were done, and the culture result from the swab showed community-associated methicillin resistant Staphylococcus aureus . This patient did not improve because her abscesses were caused by ca-MRSA which is resistant to cephalexin and other beta-lactam antibiotics. As well, an incision and drainage should have been done when she initially presented.

Abscesses caused by ca-MRSA are often multiple, appearing on the buttock and groin, as well as other parts of the body. Treatment includes incision and drainage, with the addition of antibiotics if the abscess is large or there is surrounding cellulitis, incomplete drainage, or fever Oral antibiotics effective against ca-MRSA usually include septra, doxycycline, and clindamycin.

What I do now

Key learning points:

  • Initiate empiric antibiotics which cover Group A Strep AND ca-MRSA
  • Cephalexin May Interact With Other Medications

    Cephalexin oral capsule can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.

    To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs youre taking. To find out how this drug might interact with something else youre taking, talk with your doctor or pharmacist.

    Examples of drugs that can cause interactions with cephalexin are listed below.

    How Staph Can Become Resistant M R S A

    Antibiotics are the medical treatment of choice for Staph, however, growing antibiotic resistance is a serious issue.

    The overuse of antibiotics over many years has resulted in the ever growing population of antibiotic resistant bacteria, such as MRSA. Antibiotics have become less and less effective with each passing year. Such misuse has been created by doctors prescribing antibiotics for colds which are caused by viruses, not bacteria. The commercial livestock industry has overused antibiotics which are commonly used to fatten cattle so they can go to market quicker, making these drugs less effective for people. These two factors have greatly contributed to antimicrobial resistance in bacteria like Staph.

    While antibiotics are often necessary and lifesaving, I believe they should be used with prudence. Antibiotics have a history of being misused and over-used which has contributed largely to antibiotic resistant bacteria like MRSA, VRSA and others.

    Statistics are now showing that using antibiotics for a Staph infection can double your chances of getting MRSA. Using an antibiotic that doesnt work well only makes these bacteria more resistant. Im not saying this as a scare tactic, but I want to inform you of the risks involved with antibiotics and if youre going to use them, make sure you get tested.

    Is There A Way To Prevent Getting A Bacterial Infection

    Cephalexin ( Keflex ): What is Cephalexin Used For, Dosage, Side Effects & Precautions?

    There are many ways to treat a bacterial skin infection, but the best way would be to take care of it at the first sign. This is easy for most people, but if you have a condition that could affect your immune system or you have weak immune systems because of age or illness, this task becomes harder. If you have any underlying medical conditions, you should still think about getting treatment right away so that the infection can clear up without complications.

    The best way to prevent a bacterial skin infection is washing your hands frequently and getting a good amount of sleep. Always make sure your hands are clean by washing them with soap and water or using an alcohol-based hand sanitizer that takes away the moisture from the area. Yes there is! You can prevent these infections by making sure you keep your hands clean and use hand sanitizer to kill off any bacteria that may be on your skin. If this still does not work, you can try using an over the counter ointment or cream to help reduce the number of breakouts. Many people get bacterial skin infections because they dont wash their hands properly.

    Can You Get Cephalexin Online

    In order to get cephalexin, you first need a prescription. You can get this online through your healthcare provider.

    Once you receive the prescription, you can purchase cephalexin online. Before buying any medicine on the web, though, consider these tips from the Food and Drug Administration :

    • Only use sites that require a prescription and have a pharmacist available for questions.
    • Only buy prescription drugs from licensed US pharmacies.
    • Dont share your credit card information or other personal information unless the site is secure.

    What Other Options Are There

    Unfortunately, MRSA is constantly becoming more resistant to more antibiotics. I agree with the CDC who stated it is only a matter of time before antibiotics can no longer can be relied upon.

    Additionally, antibiotics often make people so sick they are unwilling to go another round. May people have tried everything with no luck. Fortunately, there are alternative treatment choices that actually work for MRSA and have little or no side-effects.

    Great advice. In patients with multiple recurrences, do you ever recommend fucidin ointment application to the patients nares.

  • Marco TerwielJune 2, 2010 at 12:14 pmPermalink

    I deal with regular MRSA outbreaks in Nunavut, especially Arviat, where there is serious overcrowding, no running water and therefore very difficult to practice good hygiene, Moreover compliance is generally poor. There are months that no MD is on site and all MD consults are per telephone with RNs in an expanded role or if lucky a certified NP. Many of the RNs are reluctant to do an I& D because that is not in their scope of practice. The solution has been to use clindamycin iv 600mgm q 8 h or if shortstaffed 900mgm q 12 hours. That seems to work most of the time, but I am afraid of resistance and of course the negative side effects, even though so far that has not occurred. Any advice?

  • Scott FinleyJune 2, 2010 at 12:52 pmPermalink

    Most abscesses have some surrounding erythema, but require only I& D- ie. no antibiotics. Using two antibiotics would be overkill for the vast majority of these infections. Next topic: how to treat the C.difficile.

    Antibiotics Dont Help If Your Skin Is Not Infected

    Eczema causes red, itchy, and scaly skin. People with eczema often have high amounts of bacteria on their skin. But that doesnt mean that the germs are causing infection. Even so, some doctors treat eczema with antibiotics that you take by mouth to kill the germs.

    Antibiotics also dont help your itching or redness. And they dont make your eczema less severe. Plus, your skin bacteria usually come back in a month or two, if not sooner.

    You can control eczema better with lotions and other steps. To ease itching and swelling, ask your doctor about other treatments, such as creams and ointments that contain medicine. You can get them with or without a prescription.

    Different Alternative Antibiotics For Dogs

    Antibiotics are not always needed for the treatment of infections. Some veterinarians have lasers that can be used to treat bacterial infections. Others may suggest the use of warm compresses. These can help with blood flow and the circulation of white blood cells and oxygen to naturally fight infection. You may also consider looking into natural antibiotics for your pooch.

    According to Black, the antibiotic is usually well-tolerated, but it should be avoided in patients with allergies to cephalosporins. Baxt adds that there can be cross-reactivity to cephalosporins and sometimes penicillin, so anyone who is allergic to those should reconsider using cephalexin as a treatment.

    Adds Ali, the risks or side effects of using an antibiotic, such as cephalexin, include allergic reactions, rash, nausea, and diarrhea. But perhaps the most concerning side effect of using an antibiotic to treat acne is antibiotic resistance and therefore definitely a reason to approach with some caution. “Propionobacterium acnes, the bacterium responsible for acne flares, has exhibited a large rise in antibiotic resistance over the past few decades with use of antibiotics, in general,” Dhingra explains. The other concern is that prolonged cephalexin courses can introduce the risk of resistance for other bugs like Staph bacteria, making treatment of other conditions with cephalexin more difficult, he notes.

    To sum it up: before taking cephalexin, make sure you are not allergic to it, be aware of the potential side effects, and notify your doctor of any unusual reactions.

    Predisposition To Infection: Neutropenia

    Patients with neutropenia are predisposed to infection because of insufficient circulating neutrophils, lack of adequate myeloid marrow reserve, or congenital or acquired defects in neutrophil function . Neutropenia is frequently associated with mucosal or integumentary barrier disruption, and the indigenous colonizing florae are responsible for most infections. More than 20% of patients with chemotherapy-induced neutropenia develop skin and soft-tissue infections, many of which are due to hematogenous dissemination from other sites, such as the sinuses, lungs, and the alimentary tract . Important pathogens for neutropenic patients can be separated into organisms most likely to cause an initial infection and those more likely to cause a subsequent infection . Pathogens causing initial infections are usually bacteria, including both gram-negative and gram-positive organisms. Pathogens causing subsequent infections are usually antibiotic-resistant bacteria, yeast, or fungi .
