Cephalexin is the generic name for the antibiotic commonly known by brand names such as Keflex [1].
Why are some people looking for the generic name of Keflex?
Many consumers seek the generic name, cephalexin, to identify or request the less expensive version of a medication. Generic drugs contain the same active ingredients and are therapeutically equivalent to their brand-name counterparts, but are typically available at a lower cost [2].
What kind of antibiotic is cephalexin?
Cephalexin belongs to a class of antibiotics called cephalosporins [1]. It works by preventing bacteria from forming their cell walls, which leads to their death [3].
What conditions does cephalexin treat?
Cephalexin is prescribed to treat a variety of bacterial infections. These include infections of the respiratory tract, urinary tract, skin and skin structure infections, and bone infections [1][3]. It is effective against many common bacteria, but not viruses like the common cold or flu [3].
How long does it typically take for cephalexin to work?
While individual responses can vary, patients often begin to feel relief from their symptoms within 24 to 48 hours of starting cephalexin [3]. It is crucial to complete the full course of treatment as prescribed by a healthcare provider, even if symptoms improve sooner, to ensure the infection is fully eradicated and to prevent antibiotic resistance [4].
When does the patent for cephalexin expire?
Cephalexin is a well-established antibiotic, and its original patents have long expired [5]. This has allowed for the widespread availability of generic versions since the early 1990s [6].
Who manufactures generic cephalexin?
Numerous pharmaceutical companies produce generic versions of cephalexin. These manufacturers include Teva Pharmaceuticals, Aurobindo Pharma, and Sandoz, among others [7].
What are the potential side effects of cephalexin?
Common side effects associated with cephalexin can include nausea, vomiting, diarrhea, and abdominal pain [1]. Some individuals may also experience rash or itching [3]. More serious, though less common, side effects can occur, and patients should seek medical attention if they experience severe diarrhea, signs of an allergic reaction (like hives or difficulty breathing), or a new infection [1][3].
Are there alternatives to cephalexin for bacterial infections?
Yes, other antibiotics may be used to treat bacterial infections, depending on the specific type of bacteria and the location of the infection. These alternatives might include other cephalosporins or different classes of antibiotics. A healthcare provider will determine the most appropriate treatment [3].
How does cephalexin compare to other antibiotics?
Cephalexin is a first-generation cephalosporin. Other generations of cephalosporins, such as cefuroxime (second-generation) or ceftriaxone (third-generation), have broader spectrums of activity against different types of bacteria [8]. The choice of antibiotic depends on the suspected or confirmed pathogen and its susceptibility patterns [4].
What is the pricing of generic cephalexin?
The cost of generic cephalexin can vary depending on the pharmacy, dosage, and quantity. It is generally significantly less expensive than brand-name Keflex [2]. Patients can often find competitive pricing by comparing costs at different pharmacies or through discount programs [9].
