What is Cefalexin?
Cefalexin is a powerful medicine that helps your body get rid of harmful bacteria. It's part of a big family of medicines called antibiotics. Think of antibiotics as special tools that target and destroy bacteria, or stop them from growing.
How Does Cefalexin Work?
Cefalexin works by stopping bacteria from building their cell walls. Bacteria need strong cell walls to survive and grow. When cefalexin attacks these walls, the bacteria can't protect themselves and they die. This helps your body recover from the infection.
What Kinds of Infections Does Cefalexin Treat?
Cefalexin is used for many common bacterial infections. It's often prescribed for:
- Ear infections: These can be painful and affect hearing.
- Bone and joint infections: These are serious infections that need strong medicine.
- Skin infections: Such as boils, impetigo, or infected cuts.
- Bladder infections: Also known as urinary tract infections (UTIs).
- Strep throat: A common bacterial infection of the throat.
- Some types of pneumonia: An infection in the lungs.
It's important to remember that cefalexin only works for infections caused by bacteria. It will not help if you have a cold, the flu, or other infections caused by viruses.
Important Things to Know About Cefalexin
When you take cefalexin, it's important to follow your doctor's instructions carefully.
Why Finish All Your Medicine?
Even if you start feeling better, you must finish the entire course of cefalexin your doctor prescribed. If you stop taking it too soon, some bacteria might survive. These surviving bacteria can become stronger and harder to kill with antibiotics in the future. This is called antibiotic resistance.
Possible Side Effects
Like all medicines, cefalexin can sometimes cause side effects. Most side effects are mild and might include:
- Upset stomach or nausea
- Diarrhea
- Headache
If you experience any serious or unusual side effects, tell a trusted adult or your doctor right away.
When Not to Use Cefalexin
Cefalexin is not for everyone. If you have ever had an allergic reaction to penicillin or other antibiotics, it's very important to tell your doctor. An allergic reaction can be serious. Your doctor will decide if cefalexin is the right medicine for you.
