The Best Antibiotic for Children and When Does Your Child Really Need It?

How many times have you tried giving your child an antibiotic hoping their high fever would drop, or thinking it would relieve the symptoms of a common cold?

You may not have seen the results you expected — the fever persisted, and so did the symptoms. That’s because antibiotics are only meant for specific cases: bacterial infections, which can sometimes resemble viral ones. Antibiotics, however, are ineffective against viruses.

So, when does your child actually need an antibiotic? Do antibiotics treat the common cold? And what are the best antibiotics for children available in pharmacies?

What Are Antibiotics and How Do They Work?

Antibiotics are medications prescribed by doctors to eliminate bacteria that cause infections. They do not kill viruses such as influenza or measles; rather, they treat bacterial infections.

They work by preventing bacteria from growing and multiplying. There are several types of antibiotics, and your doctor determines which one is most suitable for your child.

Antibiotic Resistance

It’s important to know that some bacteria develop resistance to certain antibiotics. As a result, an antibiotic may fail to stop a bacterial infection because the bacteria are no longer affected by it.

In such cases, the doctor prescribes another antibiotic to overcome the resistant infection or prevent it from spreading.

The Difference Between Bacterial and Viral Infections

Many parents mistakenly give their children antibiotics whenever they show symptoms of a cold or other illnesses. However, it’s essential to distinguish between bacterial and viral infections — they are not the same.

The difference isn’t just that viruses are smaller than bacteria; viruses also need a host to survive, while bacteria can live independently.

Examples of viral infections:

• Chickenpox
• Common cold viruses
• Coronavirus

Examples of bacterial infections:

• Strep throat
• Skin and wound infections

Antibiotics are designed to fight bacterial infections only. They are not effective against viral illnesses, including influenza or COVID-19.

When Does a Child Need an Antibiotic?

A common misconception is that every fever or high temperature means a child needs antibiotics — believing they “fix everything.”

However, most fevers in children are caused by viruses, not bacteria, and therefore do not require antibiotics. In fact, unnecessary use may cause problems like allergic rashes, which tend to occur in some families when antibiotics are taken.

The best approach is to consult a doctor to determine whether your child truly needs an antibiotic. Only a physician can distinguish between bacterial and viral causes accurately.

How Long Should a Child Take Antibiotics?

If your child truly needs antibiotics for a bacterial infection, the treatment doesn’t last forever. It typically continues for about five days, although some cases may require a few extra days.

Regardless of the duration prescribed by the doctor, it’s crucial to complete the full course of antibiotics — even if your child seems better before finishing it. Never stop treatment early without consulting your doctor.

Do Antibiotics Treat the Common Cold?

Antibiotics are not recommended for treating colds, influenza, or other viral respiratory infections in children.

In these cases, other remedies may help, such as:

• Keeping the body well-hydrated by drinking plenty of water.
• Warm fluids like soup or broth to soothe the throat.
• Saline nasal drops or sprays to help clear mucus from the nose and sinuses.

Ultimately, only a qualified doctor can determine whether your child’s symptoms are due to a bacterial or viral infection.

Do Antibiotics Treat Sore Throat in Children?

A sore throat may sometimes indicate strep throat, which is caused by bacteria and therefore responds to antibiotics.

However, most cases of sore throat in children are viral, not bacterial.

That’s why the doctor may order a strep test. If it’s positive, the doctor will prescribe the appropriate antibiotic.

Side Effects of Antibiotics in Children

Overusing antibiotics can cause side effects, especially with frequent exposure. Common side effects include:

• Stomach upset
• Diarrhea
• Imbalance of the gut microbiome — children are particularly vulnerable during the first five years of life, which may weaken their immunity

If your child experiences diarrhea or digestive issues while taking antibiotics, probiotics or probiotic-rich foods may help restore the gut’s healthy balance.

Tips to Prevent Antibiotic Resistance

To preserve the effectiveness of antibiotics against harmful bacteria:

• Use antibiotics only for bacterial infections. Colds are caused by viruses and shouldn’t be treated with antibiotics.
• Follow the doctor’s instructions about the treatment duration.
• Never take antibiotics prescribed for another person.
• Avoid using leftover antibiotics from a previous illness.
• Ensure your child receives all recommended vaccines to prevent bacterial infections.
