Phexin Capsule (Cephalexin): Antibiotic - Bacterial Infection Treatment | for managing respiratory, skin, ear and urinary tract infections
Cephalexin Capsule, marketed under the brand names Phexin and Keflex, is a widely used antibiotic medication belonging to the cephalosporin class. Cephalexin is prescribed to treat a variety of bacterial infections caused by susceptible microorganisms.
Product Overview
Phexin Capsule is an oral antibiotic formulation containing Cephalexin, a first-generation cephalosporin antibiotic used to manage a variety of bacterial infections. It works against susceptible bacteria by interfering with the formation of their protective cell wall, which is essential for bacterial survival.
Cephalexin is commonly prescribed for certain bacterial infections affecting the respiratory tract, skin and soft tissues, urinary tract, and other susceptible sites. It should be used only when a bacterial infection is suspected or confirmed and according to the prescribed dosage and duration.

Mechanism Insights (How It Works)
Wall Targeting
Cephalexin binds to bacterial penicillin-binding proteins (PBPs), which are involved in the formation and maintenance of the bacterial cell wall.
Inhibition of Cell Wall Synthesis
By interfering with these proteins, the medicine disrupts the normal construction of the bacterial cell wall.
Bacterial Cell Breakdown
The weakened cell wall becomes unable to maintain its structural integrity, ultimately causing susceptible bacterial cells to rupture and die.
Administration Guidelines
- Take Phexin Capsule exactly as prescribed by the physician.
- It can generally be taken with or without food; taking it with food may help reduce stomach discomfort.
- Swallow the capsule with water without crushing or chewing it.
- Complete the prescribed course even if symptoms improve earlier.
- Do not use leftover antibiotics or share them with others.
Clinical Considerations
- Used for certain infections caused by bacteria susceptible to cephalexin.
- May be prescribed for infections involving the respiratory tract, skin, soft tissues, or urinary tract, depending on the causative organism.
- Does not treat viral infections such as common cold or influenza.
- Patients with a history of serious allergy to cephalosporins or other beta-lactam antibiotics should inform their healthcare provider before use.
