What is Cephalexin?

Health

Cephalexin is a prescription medication that belongs to the class of antibiotics known as cephalosporins. It is commonly used to treat various bacterial infections, such as skin infections, respiratory tract infections, and urinary tract infections.

How Does Cephalexin Work?

Cephalexin works by interfering with the formation of the bacterial cell wall, ultimately leading to the death of the bacteria. It targets and inhibits the activity of enzymes involved in cell wall synthesis, weakening the bacteria and making it easier for the immune system to clear the infection.

Indications for Cephalexin

Cephalexin is prescribed for a wide range of bacterial infections, including:

  • Skin and soft tissue infections
  • Respiratory tract infections (such as bronchitis, pneumonia, and sinusitis)
  • Urinary tract infections
  • Ear infections
  • Bone and joint infections
  • Strep throat

Administration and Dosage

Cephalexin is typically available in the form of capsules or tablets, which should be taken orally with or without food. The dosage and duration of treatment may vary depending on the type and severity of the infection, as well as the patient’s age and overall health.

It is important to follow the prescribed dosage and complete the full course of treatment, even if the symptoms improve before the medication is finished. This helps to ensure the complete eradication of the infection and prevent the development of antibiotic resistance.

Possible Side Effects

Like any medication, cephalexin can cause side effects. Common side effects may include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Stomach upset
  • Headache
  • Dizziness
  • Skin rash

If any of these side effects persist or worsen, it is important to contact a healthcare professional. In rare cases, cephalexin can cause more serious side effects, such as severe allergic reactions or liver problems. If you experience any unusual symptoms, seek immediate medical attention.

Precautions and Interactions

Before taking cephalexin, it is important to inform your healthcare provider about any existing medical conditions or allergies you may have. It is also essential to disclose all other medications, supplements, or herbal products you are currently taking, as they may interact with cephalexin.

Cephalexin may interact with certain medications, such as blood thinners, oral contraceptives, and probenecid. These interactions can affect the effectiveness of cephalexin or increase the risk of side effects. Always consult with your healthcare provider before starting cephalexin or making any changes to your current medication regimen.
