Clarifying the Name: Felexin vs. Cephalexin
For many searching for information on 'Felexin', it is important to first clarify that this is a common typographical error for the prescription antibiotic, Cephalexin. Cephalexin, sometimes known by the former brand name Keflex, belongs to a class of antibiotics called first-generation cephalosporins. The medication is designed to combat bacterial infections by disrupting the synthesis of the bacterial cell wall, which ultimately kills the bacteria. This mechanism makes it effective against a broad spectrum of susceptible bacteria, primarily gram-positive types. It is crucial to remember that Cephalexin, like all antibiotics, is ineffective against viral infections such as the common cold or flu.
Common Infections Treated with Cephalexin 500mg
The 500mg dosage of Cephalexin is a standard regimen for a variety of bacterial infections in adults and adolescents. A healthcare provider will determine the appropriate dosage and duration of treatment based on the specific type and severity of the infection. Some of the most common infections treated with Cephalexin 500mg include:
Skin and Soft Tissue Infections
Cephalexin is frequently prescribed to treat bacterial infections of the skin and underlying tissues. This can include conditions such as cellulitis, impetigo, and other superficial infections caused by susceptible Staphylococcus aureus (staph) and Streptococcus pyogenes (strep) bacteria.
Respiratory Tract Infections
The medication is effective against bacterial respiratory infections, including some forms of pneumonia and strep throat (streptococcal pharyngitis). For strep throat, a full 10-day course of therapy is typically recommended to eradicate the bacteria completely and prevent rheumatic fever.
Urinary Tract Infections (UTIs)
Cephalexin is a common choice for treating uncomplicated urinary tract infections (UTIs) caused by susceptible bacteria like E. coli, Proteus mirabilis, and Klebsiella pneumoniae. It is also used to treat acute prostatitis.
Ear Infections (Otitis Media)
Middle ear infections, known as otitis media, can be caused by various bacteria, and Cephalexin is an FDA-approved treatment option for these cases. The dosage for children is typically calculated based on their body weight.
Bone Infections
In some instances, Cephalexin is used to treat bone infections caused by susceptible Staphylococcus aureus and Proteus mirabilis.
Dosage, Administration, and Best Practices
For an adult, the standard dosage of 500mg may be prescribed to be taken every 12 hours for certain infections, or a 250mg dose may be administered every 6 hours. The exact regimen is based on the infection being treated. For most courses, treatment lasts 7 to 14 days, though for streptococcal infections, it is recommended to continue for at least 10 days.
- Take Exactly as Prescribed: Never stop taking the medication early, even if symptoms improve, as this can lead to antibiotic resistance.
- Consistency is Key: Take the medicine at regular intervals to maintain a consistent level in your system.
What Cephalexin Does Not Treat
Cephalexin does not treat viral infections, such as the common cold or flu. It is also not effective against MRSA or certain other resistant bacteria.
Comparison of Cephalexin vs. Amoxicillin
Cephalexin and Amoxicillin are both broad-spectrum antibiotics used for various infections. Key differences exist in drug class, common uses, bacterial coverage, considerations for penicillin allergy, and dosing frequency.

Side Effects and Contraindications
Cephalexin can cause side effects, most commonly gastrointestinal issues like nausea, diarrhea, vomiting, and indigestion. More serious side effects, such as severe diarrhea or signs of an allergic reaction, require immediate medical attention. Cephalexin is contraindicated in patients with a known allergy to cephalosporins, and caution is advised for those with a history of penicillin allergy due to potential cross-reactivity.
Conclusion
In summary, the medication referred to as 'Felexin 500mg' is actually Cephalexin 500mg, a widely used first-generation cephalosporin antibiotic. It is a powerful tool for fighting a variety of bacterial infections affecting the skin, respiratory tract, urinary tract, and more. For effective treatment and to prevent antibiotic resistance, it is critical to use Cephalexin only when prescribed by a healthcare professional and to complete the entire course of medication as directed. Always consult your doctor or pharmacist if you have questions about this or any other medication to ensure safe and appropriate use.
