Cefalexín

Cefalexín is a semi-synthetic cephalosporin antibiotic used to treat a variety of bacterial infections. It works by inhibiting the synthesis of the bacterial cell wall, which leads to bacterial death. Cefalexín is effective against a wide range of Gram-positive and some Gram-negative bacteria. It is commonly prescribed for infections of the skin, respiratory tract, urinary tract, and bones.

This medication is administered orally. The dosage and duration of treatment depend on the type and severity of the infection, as well as the patient's age and kidney function. It is important to complete the full course of cefalexín as prescribed by a healthcare professional, even if symptoms improve.

Common side effects of cefalexín include nausea, vomiting, diarrhea, and abdominal pain. Allergic reactions, though less common, can occur and may include rash, itching, and difficulty breathing. It is crucial to inform a doctor about any pre-existing medical conditions, especially kidney problems or a history of allergic reactions to penicillin or other cephalosporins, before starting treatment. Cefalexín may interact with certain medications, so it is advisable to disclose all current prescriptions to a healthcare provider.
