Cephalexin is a widely used antibiotic in Australia, known for its effectiveness in treating a range of bacterial infections. As a member of the cephalosporin class, cephalexin works by killing bacteria or stopping their growth, making it a valuable medicine in combating infections caused by susceptible bacteria. But what exactly is cephalexin best suited for? Here’s a detailed look at its primary uses in Australia.
Common Infections Treated with Cephalexin
In Australia, cephalexin is primarily prescribed for infections caused by bacteria in various parts of the body, including:
- Respiratory Tract Infections: Cephalexin effectively treats infections of the chest, lungs, throat, tonsils, and sinuses. It targets bacteria such as Streptococcus pneumoniae and group A beta-haemolytic streptococci, which are common culprits in these infections.
- Middle Ear Infections (Otitis Media): It is used to treat bacterial ear infections caused by Streptococcus pneumoniae, Staphylococcus aureus, and other susceptible organisms.
- Skin and Soft Tissue Infections: Cephalexin is effective against skin infections like cellulitis, abscesses, and infected wounds, commonly caused by Staphylococcus aureus and Streptococcus pyogenes.
- Genitourinary Tract Infections: This includes infections of the kidney, bladder, and prostate, often caused by Escherichia coli, Proteus mirabilis, and Klebsiella species. Cephalexin is used to treat acute prostatitis and uncomplicated urinary tract infections.
How Cephalexin Works
Cephalexin belongs to the cephalosporin group of antibiotics, which kill bacteria by interfering with their cell wall formation. Without a proper cell wall, bacteria cannot survive, leading to their destruction and the resolution of the infection.
What Cephalexin is Not Used For
It is important to note that cephalexin is not effective against viral infections such as the common cold or flu. It also is not indicated for infections of the brain or spinal column, as its effectiveness in these areas has not been established.
Why Cephalexin is a Preferred Choice in Australia
- Broad Effectiveness: Cephalexin covers many common bacteria responsible for infections Australians frequently encounter.
- Safety Profile: It is generally well tolerated with a low incidence of serious side effects.
- Versatility: Available in capsules and oral suspensions, making it suitable for both adults and children.
- Accessibility: Available by prescription, ensuring it is used under medical supervision.
Important Considerations
- Always use cephalexin as prescribed by your healthcare provider.
- Complete the full course of treatment to prevent recurrence and resistance.
- Inform your doctor if you have allergies to penicillin or other cephalosporins.
- Report any side effects or unusual symptoms promptly.
Summary
Cephalexin is best used in Australia for treating bacterial infections of the respiratory tract, ears, skin, and genitourinary system. Its ability to effectively target common bacteria while maintaining a good safety profile makes it a trusted antibiotic choice. Remember, cephalexin should only be used under medical guidance and is not suitable for viral infections.
