What is Cefalexin?

Cefalexin is an antibiotic used to treat bacterial infections. It belongs to the cephalosporin group of antibiotics and works by killing bacteria or stopping their growth.

What Infections Does It Treat?

Doctors prescribe Cefalexin for infections like:

• Skin infections (such as infected wounds or boils)
• Throat infections (like tonsillitis)
• Urinary tract infections (UTIs)
• Ear infections
• Lung infections (such as bronchitis or mild pneumonia)

How Does It Work?

Cefalexin kills bacteria by breaking their protective walls, making it easier for the body to fight the infection. However, it does not work on viruses, so it won’t help with colds or the flu.

How to Take Cefalexin

• Usually taken as capsules, tablets, or liquid.
• Can be taken with or without food.
• Always finish the full course prescribed by the doctor, even if you feel better.
• Take it at regular times to keep the medicine level steady in your body.

Possible Side Effects

Like all medicines, Cefalexin can have side effects. Common ones include:

• Nausea or vomiting
• Diarrhea
• Stomach pain
• Headache
• Skin rash (if allergic)

If you have severe side effects like difficulty breathing or swelling, seek medical help immediately.

Who Should Not Take Cefalexin?

Cefalexin may not be safe for everyone. Inform your doctor if you:

• Are allergic to penicillin or cephalosporin antibiotics
• Have kidney disease
• Have a history of severe allergic reactions to antibiotics

Important Things to Remember

Complete the full course – Stopping early may cause the infection to return.
Avoid alcohol while taking the medicine to reduce stomach issues.
Tell your doctor if you take other medications, as Cefalexin may interact with them.

Conclusion

Cefalexin is a commonly used antibiotic that effectively treats bacterial infections. It is important to take it exactly as prescribed and to be aware of possible side effects. If you have any doubts or reactions, consult a doctor for advice.
