Top 5 misconceptions about antibiotics

Antibiotics have fundamentally reshaped the landscape of modern medicine, emerging as indispensable allies in the battle against infectious diseases that were once deemed perilous or even fatal. These powerful medications have revolutionised healthcare by transforming previously life-threatening infections into treatable conditions, leading to a remarkable decrease in mortality rates and an enhanced quality of life for countless individuals.

However, the reckless misuse and overprescription of antibiotics—particularly in cases of sore throat, where the majority are caused by viruses—have become pressing concerns, posing a severe threat to their long-term effectiveness.

This alarming trend is driving the rise of antimicrobial resistance (AMR), an issue that jeopardises not only individual health but also public health on a global scale. If this crisis is allowed to escalate unchecked, we may find ourselves confronting a chilling post-antibiotic era, wherein even minor infections could evolve into serious health risks, and routine medical procedures could become fraught with peril.

In Malaysia, the challenge is compounded by a widespread lack of awareness and persistent misconceptions surrounding antibiotics. Despite ongoing educational campaigns and initiatives aimed at raising awareness, many people still hold beliefs that can lead to detrimental practices, such as self-medication or prematurely discontinuing prescribed treatments.

This is particularly concerning in cases of sore throat, where unnecessary antibiotic use contributes significantly to resistance. Many sore throats are viral in nature and do not require antibiotics. In such cases, managing symptoms with pain relievers, hydration, and throat sprays containing anti-inflammatory agents can provide effective relief, as supported by recently published multidisciplinary sore throat consensus in Malaysia. 

It is imperative to confront these misconceptions head-on, providing clear, accurate information to promote responsible antibiotic use among the public and healthcare providers alike. The urgency of this mission cannot be overstated, as each day that passes without meaningful intervention further jeopardizes the medical advancements that have been achieved using these lifesaving medications. It is crucial that we act decisively to foster a culture of understanding and responsibility surrounding antibiotic use, ensuring a healthier future for all. Here are five misconceptions that need to be addressed:

Myth 1: Antibiotics Can Cure Viral Infections

One of the most persistent misconceptions is that antibiotics can treat viral infections such as the flu, colds, or sore throat, the latter of which is commonly caused by viruses. This is false; antibiotics are only effective against bacterial infections, yet they continue to be misused for viral illnesses. Globally, studies show that at least 50% of antibiotics are inappropriately prescribed for viral infections, contributing to unnecessary resistance.

Myth 2: Stopping Antibiotics Early Is Safe

Patients often stop taking antibiotics once they feel better, assuming the infection is gone. This premature discontinuation is a major driver of resistance. Bacteria that survive incomplete treatment can adapt, mutate, and become resistant, making future infections more difficult to treat. Completing the full prescribed course is essential to ensure all harmful bacteria are eliminated.

Myth 3: Antibiotic Resistance Affects People

A common misunderstanding is that the human body develops resistance to antibiotics. In reality, it is the bacteria that become resistant, rendering treatments ineffective. Rampant misuse of antibiotics in sore throat, cold, or flu—conditions that are mainly caused by viruses—leads to bacterial resistance, making previously treatable infections harder to manage. As resistance increases, infections that were once easily cured with antibiotics may require stronger, more expensive medications that may not always work.

Myth 4: Sharing or Antibiotics Is Harmless

Many Malaysians keep leftover antibiotics for future use or share them with family members, assuming it is a practical solution. This practice is extremely dangerous. Each infection requires a specific antibiotic, dosage, and duration of treatment. Taking the wrong medication—or the wrong dose—not only fails to treat the infection but also contributes to resistance.

Myth 5: Antibiotics Are Necessary

Not every bacterial infection requires antibiotics. Mild bacterial infections often resolve on their own with proper rest and hydration. Overprescription of antibiotics for minor infections—especially in cases of sore throat that are mainly viral—only accelerates resistance, reduces treatment options, and increases the risk of superbugs. In such cases, symptomatic treatment, including throat sprays with low-dose anti-inflammatory medication, may be more appropriate, as recommended by Malaysian medical experts.

The challenge of antimicrobial resistance (AMR) presents an important opportunity for positive change. Each of us has the potential to contribute to a healthier future by making informed choices and using antibiotics responsibly. By encouraging those around us to adopt similar practices, we can help ensure the effectiveness of these vital medicines for future generations.

Malaysia has already made notable progress in raising awareness about AMR. With ongoing education, the implementation of stronger policies, and a united commitment to responsible antibiotic use, we can collectively work to slow down resistance and safeguard public health. Simple, responsible actions—such as completing a full course of antibiotics, avoiding self-medication, and educating others—can make a significant impact.

Rather than viewing the possibility of a post-antibiotic era with fear, we can focus on the potential for continued medical advancements, where antibiotics remain effective tools against infections and our healthcare system becomes even more resilient. It is essential to recognise that antibiotics are not always necessary, particularly for common conditions like sore throat, colds, and flu, which are primarily caused by viruses.

In such cases, symptomatic treatment with throat sprays containing low-dose anti-inflammatory medication is a recommended alternative. Together, we have the power to redefine the narrative surrounding antibiotics—not as a resource we lost through misuse but as one we protect and enhance through knowledge, responsibility, and proactive efforts.
