Cephalexin 500 mg capsules are a commonly prescribed antibiotic in Australia, used to treat a variety of bacterial infections. As a member of the cephalosporin class of antibiotics, cephalexin works by killing bacteria responsible for infections in different parts of the body. This blog post provides an overview of what cephalexin 500 mg capsules are used for, how they work, dosage guidelines, and important safety information relevant to Australians.
What is Cephalexin 500 mg Used For?
Cephalexin is prescribed to treat infections caused by susceptible bacteria, including:
- Respiratory tract infections: Such as infections of the throat, tonsils, sinuses, chest, and lungs.
- Ear infections: Middle ear infections (otitis media).
- Skin and soft tissue infections: Including cellulitis and infected wounds.
- Urinary tract infections (UTIs): Including infections of the bladder and kidneys.
- Bone infections: Sometimes used in osteomyelitis.
- Other bacterial infections: When caused by bacteria sensitive to cephalexin.
It is important to note that cephalexin is only effective against bacterial infections and will not work for viral infections like the common cold or flu.
How Does Cephalexin Work?
Cephalexin belongs to the cephalosporin group of antibiotics. It works by interfering with the bacteria’s cell wall formation, causing the bacterial cells to rupture and die. This action helps clear the infection from the body.
Dosage and Administration in Australia
The typical adult dose for cephalexin capsules is between 250 mg to 500 mg taken every 6 hours, depending on the severity and type of infection. For some mild infections, a dose of 500 mg every 12 hours may be prescribed. Treatment usually lasts from 7 to 14 days, but it is crucial to complete the full course as directed by your doctor to prevent the infection from returning or worsening.
Cephalexin can be taken with or without food. For better absorption and to reduce stomach upset, some people prefer taking it with food.
Important Precautions and Side Effects
- Complete the full course: Even if you feel better after a few days, finishing the entire prescribed course ensures the infection is fully treated.
- Allergic reactions: If you have a known allergy to cephalosporins or penicillin, inform your doctor before taking cephalexin. Signs of an allergic reaction include rash, itching, swelling, dizziness, or difficulty breathing.
- Common side effects: May include nausea, vomiting, diarrhea, stomach pain, or yeast infections. If side effects are severe or persistent, seek medical advice.
- Drug interactions: Inform your healthcare provider about all medications you are taking, as cephalexin can interact with certain drugs.
- Kidney function: Dosage adjustments may be necessary for people with kidney problems.
Availability in Australia
Cephalexin 500 mg capsules are available by prescription only in Australia. Brands such as APO-Cephalexin are commonly dispensed. It is important to buy cephalexin from registered pharmacies and use it under medical supervision.
When to See a Doctor
If your symptoms do not improve within a few days of starting cephalexin, or if you experience severe side effects such as allergic reactions, persistent diarrhea, or signs of a new infection, contact your healthcare provider promptly.
Summary
Cephalexin 500 mg capsules are an effective antibiotic widely used in Australia to treat bacterial infections affecting the respiratory tract, skin, urinary tract, and more. By disrupting bacterial cell walls, cephalexin helps clear infections and promote recovery. Always follow your doctor’s instructions carefully, complete the full course, and report any unusual symptoms to your healthcare professional.
