Cefalexin

Cefalexin is a first-generation cephalosporin antibiotic used to treat a variety of bacterial infections. It is effective against a wide range of Gram-positive and Gram-negative bacteria, including Streptococcus, Staphylococcus, and Haemophilus influenzae. Cefalexin works by inhibiting the synthesis of bacterial cell walls, leading to the death of the bacteria.

Cefalexin is available in oral and intravenous forms. The oral form is typically taken twice a day, while the intravenous form is administered through a vein. The dosage and duration of treatment depend on the type and severity of the infection, as well as the patient's age and overall health.

Common side effects of cefalexin include nausea, vomiting, and diarrhea. Serious side effects are rare but can include allergic reactions, liver problems, and seizures. It is important to complete the full course of antibiotics, even if symptoms improve, to ensure the infection is fully treated.

Cefalexin should be used with caution in patients with a history of allergic reactions to penicillin or cephalosporins, as well as in patients with liver or kidney disease. It is also not recommended for use in children under the age of 8 due to the risk of seizures. Always consult a healthcare professional before starting any antibiotic treatment.
