What is Cephalexin?

Cefalexin is a cephalosporin antibiotic. Doctors prescribe it to treat certain bacterial infections. It kills susceptible bacteria or inhibits their growth. But it doesn’t work for viral infections like cold or flu.

In some countries, it is also spelt “cephalexin.” It comes as capsules, tablets and liquid medicine. The right form, dose and duration of treatment is determined by a healthcare professional because each infection and each patient is different.

Cefalexin Uses

Cefalexin is used to treat certain susceptible bacterial infections in the following areas: A doctor may prescribe cefalexin for the following:

• Skin and soft tissue
• Urinary tract infection
• Ear
• Throat and airways
• Bone

But Cefalexin is not effective against all bacteria. So a doctor might weigh your symptoms or medical history or test results before prescribing it.

How Cefalexin works?

Bacteria need a tough cell wall for protection to survive. Cefalexin messes with building this wall. This wipes out the sensitive bacteria and enhances the infection.

You might start to feel better after a few days but it is important to keep taking the medicine for the full time prescribed. If you stop your treatment early or miss doses, the infection may not be fully treated and this can lead to antibiotic resistance.

Safe Dosage of Cefalexin

Take Cefalexin exactly as your doctor or chemist tells you. Usually it can be taken with food or without food. It may cause stomach discomfort, so taking it with food may help.

Observe only these simple precautions:

• Take each dose at the time scheduled.
• Take tablets or capsules with water.
• Shake the liquid medicine well before you measure it.
• Liquid doses should be given with an appropriate oral syringe or medicine spoon.
• Follow the suggested course of treatment.
• Don’t share your antibiotic with someone else.
• Don’t use old antibiotics for a new illness.

The appropriate dose depends on the infection, age, body weight, kidney function and other health factors. Therefore, this article does not recommend an individual dose.

What If You Take Too Much?

If you miss a dose, take it when you remember. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not take two doses at once to make up for a missed dose.

If you are unsure, check the leaflet that comes with the medicine or ask your chemist. Instructions for products can vary.

Common Side Effects of Cefalexin

Like all medicines, Cefalexin can cause side effects, although not everybody gets them. Some common effects include:

• Diarrhoea
• Vomiting or nausea
• Upset stomach or indigestion
• Headache.
• Itching or discharge from the genitals

These effects are usually small. But if they are serious, last a long time, or worry you, talk to a healthcare professional.

• Face, lips, mouth, tongue, or throat swelling
• Difficulty swallowing or difficulty breathing

Cefalexin and antimicrobial resistance

Antibiotic resistance occurs when bacteria change and medicines become less effective against them. the risk is minimised by the use of Cefalexin only as prescribed by a qualified professional. Also, be certain to take it exactly as directed and not to save doses for later use.

Frequently Asked Question

Is Cefalexin a powerful antibiotic?

“Strong” is not a very useful word for antibiotics. Cefalexin could be effective against some susceptible bacteria, but another antibiotic might be better for other infections.

Does Cefalexin cure UTI?

A doctor may prescribe Cefalexin for certain bacterial urinary tract infections. But the correct treatment depends on the patient, local resistance patterns and sometimes a urine test.

Does Cefalexin cure sore throat?

It can be used to treat some bacterial throat infections when prescribed. But many sore throats are caused by a virus, and antibiotics don’t work on viruses.

Yes, it can usually be taken with or without food. Some people find taking it with food helps reduce stomach irritation.

Cefalexin how fast does it work?

For some people it may start to improve in a few days. But the response time varies. Call your doctor if symptoms get worse or do not improve as expected.

Nope. Continue to take it as long as your doctor tells you to, even if you start feeling better. If you stop too soon the infection may come back.

Nope. Both are beta-lactam antibiotics but they are in different groups and do not provide exactly the same coverage of bacteria.
