Cephadex 500 Capsule (Cephalexin) – Powerful Antibiotic for Bacterial Infections

Cephadex 500 Capsule is a high-potency cephalosporin antibiotic containing 500mg of cephalexin, designed to effectively combat moderate to severe bacterial infections. This stronger formulation is particularly useful for treating respiratory tract infections, skin and soft tissue infections, urinary tract infections, and bone infections. As a bactericidal antibiotic, it actively kills susceptible bacteria rather than just inhibiting their growth, providing faster relief from infection symptoms. The higher 500mg strength allows for less frequent dosing while maintaining therapeutic effectiveness.

The 500mg strength provides higher antibiotic concentration, allowing for less frequent dosing while effectively treating more serious infections.

Yes, it’s commonly prescribed for dental abscesses and other oral infections, but always follow your dentist’s instructions.

Q5. How long until I see improvement?

While no direct interaction occurs, alcohol may increase gastrointestinal side effects and impair immune function, so moderation is advised.
