Understanding Fever Medicines

A fever is one of the body's common responses to infection or illness. When your temperature rises, it can leave you feeling tired, uncomfortable, sweaty, or generally unwell.

Fever medicines can help reduce a high temperature and make you feel more comfortable, but they don't necessarily treat the underlying cause of the fever.

Understanding how these medicines work and when to use them can help you manage a fever safely.

What Is a Fever?

A fever occurs when your body temperature rises above its normal range, usually as part of the body's response to an infection or another condition.

Fever itself isn't always dangerous. In many cases, it's a sign that your immune system is responding to something happening in your body.

The important thing is to consider the person's overall condition, not just the number shown on a thermometer.

What Are Fever Medicines?

Medicines used to reduce fever are commonly called antipyretics.

Common examples include paracetamol (acetaminophen) and, in appropriate situations, ibuprofen.

These medicines can reduce fever and relieve associated discomfort such as headaches and body aches.

However, they don't necessarily eliminate the infection or condition causing the fever.

How Do Fever Medicines Work?

Fever medicines work by influencing the body's temperature-regulating processes.

For example, paracetamol can reduce fever by affecting chemical signals involved in temperature regulation.

Ibuprofen belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). It can reduce fever as well as pain and inflammation.

The two medicines aren't interchangeable for everyone, so choosing between them should take your individual circumstances into account.

When Should You Take Fever Medicine?

You don't necessarily need medicine every time you have a mild fever.

Fever medicines are often used when the person is uncomfortable, has significant aches or headaches, or when a healthcare professional recommends them.

If you're unsure whether you or someone in your care needs fever medicine, speak with a pharmacist or healthcare professional.

Paracetamol for Fever

Paracetamol is commonly used to reduce fever and relieve mild to moderate pain.

It's available in different formulations and strengths, including products intended for adults and children.

However, taking too much paracetamol can cause serious liver damage.

Always check the strength of the product and follow the recommended dose.

Be particularly careful when using combination cold and flu products because some may already contain paracetamol.

Ibuprofen for Fever

Ibuprofen can also reduce fever and relieve pain and inflammation.

However, it isn't suitable for everyone.

People with certain stomach, kidney, heart, or other health problems may need to avoid it or use it only under professional guidance.

If you're unsure whether ibuprofen is appropriate for you or your child, ask a pharmacist or healthcare professional.

Fever Medicines for Children

Children require particular care when using fever medicines.

The appropriate medicine and dose can depend on the child's age, weight, health, and the specific product being used.

Never give a child an adult dose simply because they have a similar fever.

Always follow the product's instructions or advice from a qualified healthcare professional.

If an infant or child has a fever and you're concerned about their condition, seek medical advice rather than relying solely on fever medicine.

Can You Take Paracetamol and Ibuprofen Together?

Some people may be advised to use both medicines, but this isn't something you should automatically do.

Using multiple medicines increases the chance of dosing mistakes.

If you are considering taking paracetamol and ibuprofen together or alternating them, ask a pharmacist or healthcare professional for advice about the appropriate approach.

Don't Take More Than the Recommended Dose

Taking extra fever medicine won't necessarily make your temperature return to normal faster.

It can instead increase the risk of serious side effects.

Always check:

• The medicine's strength.
• The recommended dose.
• How often it should be taken.
• The maximum amount that can be taken in a given period.

If you're unsure, ask your pharmacist.

Check Other Medicines for Duplicate Ingredients

Cold and flu products often contain several active ingredients.

Some may contain paracetamol or another fever-reducing medicine.

If you take an additional fever medicine without checking the label, you could accidentally exceed the recommended amount.

Always read the active ingredients before combining products.

Stay Hydrated

When you have a fever, your body may lose more fluid through sweating and increased breathing.

Drinking enough fluids can help prevent dehydration.

Water is usually a good option, while other suitable fluids can also contribute to hydration.

If someone is unable to drink, is vomiting repeatedly, or shows signs of significant dehydration, medical attention may be necessary.

Rest Can Help

Your body may need extra rest while dealing with an infection or illness.

Getting enough rest and avoiding unnecessary physical exertion can support recovery.

Fever medicine may make you feel more comfortable, but rest and hydration can also be important parts of managing a fever.

When Should You See a Doctor?

A fever can have many causes, and sometimes the underlying condition needs medical treatment.

Speak with a healthcare professional if:

• The fever is persistent.
• The person is becoming increasingly unwell.
• Symptoms are severe or unusual.
• There are signs of dehydration.
• The fever keeps returning.
• You are concerned about a baby, young child, older adult, or someone with significant health problems.

The appropriate response can depend on the person's age, symptoms, medical history, and the cause of the fever.

When Is a Fever an Emergency?

Seek urgent medical attention if a fever occurs alongside serious symptoms such as:

• Difficulty breathing.
• Severe confusion.
• Loss of consciousness.
• Seizures.
• Severe dehydration.
• A serious rash.
• Severe headache with other concerning symptoms.
• Significant weakness or deterioration.

A fever accompanied by serious symptoms should not simply be treated with an over-the-counter medicine at home.

What About Antibiotics?

Fever does not automatically mean you need an antibiotic.

Many fevers are caused by viral infections, and antibiotics do not treat viruses.

Antibiotics should only be used when appropriately prescribed or recommended for a bacterial infection.

Never take leftover antibiotics simply because you have a fever.

Ask Your Pharmacist

A pharmacist can help you choose an appropriate fever medicine and explain how to use it safely.

You can ask:

Which fever medicine is suitable for me?

What dose should I take?

Can I take it with my other medicines?

Is it safe for my child?

How often can I take it?

What symptoms mean I should see a doctor?

Final Thoughts

Fever medicines such as paracetamol and ibuprofen can help reduce fever and relieve discomfort, but they don't necessarily treat the underlying cause.

Use them according to the instructions, avoid exceeding the recommended dose, check other medicines for duplicate ingredients, and ask a pharmacist if you're unsure.

Most importantly, pay attention to the person's overall condition. A fever accompanied by serious or worsening symptoms may require medical attention rather than simple fever treatment.
