Uses of Cephalexin 500 mg
How Cephalexin 500 mg Works
Cephalexin 500 mg belongs to the cephalosporin group of antibiotics which function by targeting the bacterial cell wall synthesis. The active ingredient, Cephalexin, interferes with enzymes responsible for building the bacterial cell wall, thereby weakening it. This action causes the bacteria to burst and die, effectively stopping the spread of infection in the body.
This mode of action is effective against a broad spectrum of gram-positive and some gram-negative bacteria. Because it targets only bacteria, Cephalexin does not work against viral infections such as the common cold or flu.
How to take Cephalexin 500 mg
Always take Cephalexin 500 mg exactly as prescribed by your healthcare provider. The tablet should be swallowed whole with water, and can be taken with or without food. For best results, maintain a consistent dosing schedule.
Do not skip doses and complete the full course of treatment even if symptoms improve early, to prevent the infection from returning or worsening. If you miss a dose, take it as soon as you remember unless it is almost time for the next dose. Do not double the dose to make up for a missed one.
