What is Cephalexin?
Cephalexin is a medication that belongs to the class of drugs known as cephalosporin antibiotics. It is used to treat infections caused by bacteria, including pneumonia and other respiratory tract infections, as well as bone, skin, ears, genitals, and urinary tract infections [1]. It is also known by brand names such as Keflet, Keflex, Keftab, and Panixine Disperdose.
The medication kills bacteria, making it an effective treatment for bacterial infections. However, it's important to note that cephalexin, like other antibiotics, will not work for colds, flu, or other viral infections[1].
Uses and benefits of Cephalexin
Treats bacterial infections: Cephalexin is effective against many bacteria, including Streptococcus, Staphylococcus, E. coli, and Klebsiella pneumonia. It is commonly used to treat infections of the skin, urinary tract, respiratory tract, and ear [2].
Oral administration: Cephalexin is available orally, making it easy for patients to take at home. It is usually taken 2 to 4 times a day for 7 to 14 days, depending on the type and severity of the infection [3].
Well-tolerated: Cephalexin is generally well-tolerated by most patients. Side effects are rare but may include nausea, vomiting, diarrhoea, and allergic reactions. No major safety issues have been observed with cephalexin over its many decades [3].
Effective against resistant bacteria: Cephalexin remains effective against many bacteria resistant to other antibiotics like penicillin. This makes it a valuable option for treating infections that do not respond to other medications [4].
Affordable: As an older, generic medication, cephalexin is relatively inexpensive compared to newer antibiotics. This makes it an accessible treatment option for many patients who cannot afford more costly medications.
Cephalexin is a safe, effective, and affordable antibiotic widely used for over 40 years to treat various bacterial infections [3]. Its oral administration and well-tolerated nature make it a convenient choice for many patients.

Can Cephalexin treat bacterial vaginosis?
Bacterial vaginosis is a common condition characterized by an imbalance in the normal vaginal flora, with a decrease in lactobacilli and an increase in anaerobic bacteria [5]. The treatment for bacterial vaginosis typically involves antibiotics such as metronidazole or clindamycin [6].

More research is needed to fully understand the role of cephalexin in treating bacterial vaginosis. As always, it is advisable to consult your healthcare provider before starting any new medication.
