Cephalexin is an antibiotic medication that belongs to the class of drugs known as cephalosporins. It is commonly prescribed to treat a wide range of bacterial infections by stopping the growth of bacteria. Cephalexin capsules are effective against infections of the respiratory tract, skin, ears, bones, and urinary tract. They work by interfering with the formation of bacterial cell walls, ultimately causing the bacteria to die.
Cephalexin is usually taken orally, with or without food, as directed by a healthcare provider. The dosage and length of treatment depend on the type and severity of the infection as well as the patient’s age and medical condition. It is important to complete the full course of medication, even if symptoms improve early, to prevent the infection from returning and to reduce the risk of antibiotic resistance.
Common side effects of cephalexin may include nausea, diarrhea, stomach pain, and dizziness. Serious allergic reactions are rare but may involve rash, swelling, or difficulty breathing, requiring immediate medical attention. Cephalexin should not be used for viral infections such as the common cold or flu. Patients with known allergies to penicillin or cephalosporins should consult their doctor before use.
