Understanding Cephalexin

Cephalexin is a type of cephalosporin antibiotic. It is used to kill certain types of bacteria by interfering with the formation of the bacteria’s cell wall, causing it to rupture and die. It’s crucial to note that cephalexin won’t work for viral infections, such as the common cold or flu.

Common Uses of Cephalexin

Cephalexin is widely prescribed for various bacterial infections. Below are some of its common applications:

Respiratory Tract Infections

• Cephalexin is often prescribed for infections of the respiratory tract, including pharyngitis, tonsillitis, bronchitis, and pneumonia when these are caused by susceptible bacteria.

Skin Infections

• In dermatological terms, cephalexin is effective against skin infections such as cellulitis, impetigo, and boils, typically caused by streptococcus and staphylococcus bacteria.

Urinary Tract Infections

• For urinary tract infections (UTIs), cephalexin can be highly effective, particularly for uncomplicated cases caused by bacteria such as E. coli.

How Cephalexin Works

Cephalexin disrupts the synthesis of the bacterial cell wall. By inhibiting enzymes involved in the wall-building process, the antibiotic causes the bacterium to weaken and ultimately rupture. This action is highly effective against gram-positive and certain gram-negative bacteria.

Precautions and Side Effects

Common side effects may include gastrointestinal issues like diarrhea, nausea, and vomiting. More serious risks include allergic reactions. It is important to:

• Complete the prescribed course, even if symptoms improve before the medication is finished, to prevent resistance.
• Consult healthcare providers if severe side effects occur, such as severe diarrhea, chest pain, or unusual bleeding.
