Misuse of Antibiotics puts you at risk.

When used inappropriately, it can result in serious infections, longer recovery time, and loss of effectiveness for future treatments, due to infections becoming antibiotic-resistant.
Follow your doctor's advice.

Antibiotics do not work on viruses

Antibiotics will not help you recover faster from viral infections such as flu or the common cold.
Antibiotics only work on bacterial infections.


When are antibiotics required?

Antibiotics are not required for viral infections because they DO NOT work on viruses. Common viral infections include:

Flu (Influenza)

Common cold

COVID-19

HFMD (Hand Foot Mouth Disease)

Viral symptoms usually go away with time and symptomatic relief.


What you should do if you are down with the common cold or flu:

Get plenty of rest

Stay hydrated

Practice good hygiene habits to prevent the infection from spreading

Consult your doctor if you do not get better

Antibiotics kill or slow down the growth of bacteria. Hence, they are required for bacterial infections, such as:

Strep throat

Whooping cough

Tuberculosis

What you should do:

Follow your doctor’s advice exactly when taking antibiotics

Common side effects of antibiotics

When your doctor prescribes antibiotics to treat your infection, the benefits outweigh the risks. However, side effects may occur as antibiotics destroy both good and bad bacteria.

Nausea or vomiting

Diarrhoea

Bloating

Loss of appetite

Your doctor may then prescribe probiotic tablets along with your antibiotics to maintain and restore good bacteria. If you start developing other symptoms like allergic skin rashes due to the antibiotics or/and your side effects become worrisome, you should consult a doctor immediately.

Consequences of
antibiotics misuse

Overuse or misuse of antibiotics can lead to antibiotic resistance. This reduces the effectiveness of antibiotics in treating infections when they are really needed. This can lead to undesirable consequences as illustrated below:

Drug-resistant bugs

Bacteria in the body become resistant to antibiotics – developing the ability to resist the drugs designed to kill them.

Increased medical costs

Complications caused by antibiotic-resistant bacteria can increase the length of hospital stay and the cost of medical care.

Increased health risks

Without antibiotics that work, illnesses caused by antibiotic-resistant bacteria are harder or impossible to treat, and can lead to disability and death.

If left unchecked, it is projected that antimicrobial resistance (AMR) could cause as many as 10 million deaths worldwide by 2050 - which is higher than death attributed to diabetes (1.5 million) and cancer (8.2 million).

What is the difference between antibiotics and antimicrobials?

Antibiotics are a specific type of antimicrobial that is used to treat bacterial infections. Meanwhile, antimicrobial is a broad term that includes antibiotics, antivirals, antiparasites, and antifungals which treat infections caused by bacteria, viruses, parasites, and fungi respectively.

What is antimicrobial resistance?

Antimicrobial resistance (AMR) occurs when microorganisms (bacteria, viruses, parasites, and fungi) found in people, animals, food and the environment develop resistance and no longer respond to medication designed to kill them.

As a result, antibiotics and other antimicrobial medicines become ineffective, making infections increasingly difficult or impossible to treat.

AMR is one of the world’s most urgent public health problems, as it can affect people at any stage of life, as well as the healthcare, veterinary, and agriculture industries.

How does AMR spread?

Patients consume antibiotics inappropriately and develop drug-resistant bacteria.

Drug-resistant bacteria spread to other patients through unclean facilities and poor hygiene.

Human, Animal, Food & Environment

Animals and crops are given antibiotics inappropriately and develop drug-resistant bacteria. The bacteria remain on the crops and in the meat of the animals.

Drug-resistant bacteria spread to humans through food, the environment (water, soil, air), or by direct human-animal contact.

Drug-resistant bacteria spread to the general public.

Preventing antibiotics and antimicrobial resistance

Do take antibiotics exactly as advised by your doctor

Do go for timely vaccinations

Do practise good hygiene and adopt a healthy lifestyle

Do consume thoroughly cooked food and clean water

Fight the spread of bacteria by practising good hygiene such as proper handwashing with soap and water, proper preparation of food and keeping up to date with your vaccinations. It’s best not to get sick in the first place!

Don’t use antibiotics for the flu or common cold

Don’t adjust dosage on your own

Don’t keep antibiotics for future illnesses

Don’t share antibiotics with others

When you are sick, always see your doctor who will prescribe medicine for you according to your condition.
Let’s all play our part in preventing antibiotic and antimicrobial resistance.

Frequently Asked Questions (FAQs)

Antibiotics DO NOT work on viruses that cause influenza, and DO NOT speed up recovery from viral infections such as flu, the common cold or COVID-19.

Viruses have different cell structure from bacteria and replicate in a different way, making antibiotics ineffective against viral infections.

Please do not pressure your doctor to prescribe antibiotics.

When prescribed, please take antibiotics exactly as per your doctor’s advice.

Adjusting your treatment makes antibiotics less effective. Even if you think that you have recovered, some of the bacteria that made you ill may still be in your body. This increases the risk of that bacteria becoming resistant to the type of antibiotics you took.

Should you have any concerns about taking antibiotics, please discuss with your doctor.

Antibiotics should only be used with your doctor’s prescription. Bacterial and viral infections can bring about similar symptoms like fever, cough and nausea, making it hard for an untrained eye to distinguish between the two.

*If you have any leftover antibiotics, you can dispose them at restructured or private hospitals, and retail pharmacies with pharmacist counters like Guardian, Unity and Watsons.

A doctor’s consultation is needed to determine the type of infection one has, before he/she can take antibiotics. Sometimes, additional blood or urine tests, or X-rays may be needed to confirm a diagnosis.

If antibiotics are needed, the doctor will then prescribe the type of antibiotics and the appropriate dosage to treat the infection.

Having green phlegm is not always a sign of a bacterial infection that requires antibiotics to get better. More white blood cells are produced in our body during infections which can be caused by viruses or bacteria. When large amounts of white blood cells are present in your phlegm, it may appear green.

Therefore, coloured phlegm does not mean you need antibiotics.

Symptoms of bacterial and viral infections can be similar for upper respiratory tract infections. Differentiating between the two requires medical assessment and you should consult your doctor for the treatment you need.
