How Cephadex 500 mg Works
Think of Cephalexin as a bacteria-busting wall breaker. It prevents bacteria from building their protective cell walls — the structural foundation they need to survive.
Mechanism of Action
Cephalexin targets and blocks an enzyme involved in making the bacterial cell wall. Without this enzyme, bacteria can’t survive, and your immune system clears them out faster.
Spectrum of Activity
Cephalexin is effective against a range of Gram-positive bacteria and some Gram-negative strains like E. coli and Klebsiella.
Cephadex 500 mg Dosage and Administration
Typical Adult Dosage
The standard dose for adults is 500 mg every 12 hours for 7–14 days, depending on the type and severity of the infection.
Pediatric Usage Guidelines
While 500 mg may be too high for small children, Cephalexin is available in liquid suspensions that allow for weight-based dosing in pediatric patients.
Missed Dose? What to Do
Take the missed dose as soon as you remember. If it’s almost time for your next dose, skip the missed one. Don’t double up.
Overdose Warning
Too much Cephalexin can lead to severe stomach upset, diarrhea, or kidney issues. Contact a healthcare provider immediately in case of overdose.
