Firstly, the antibiotics won’t work, as they only act against bacteria while the cold is caused by a virus.
Secondly, you will be contributing to arguably the world’s gravest health threat – antibiotic resistance.
The misuse of antibiotics is one of the main causes behind why they are becoming increasingly ineffective against many diseases, including pneumonia, tuberculosis, blood disorders, gonorrhoea and food-borne diseases.
Health leaders keep ringing the alarm bell.
“The world is facing an antibiotic apocalypse,” said Britain’s Chief Medical Officer Dame Sally Davies.
“It may spell the end of modern medicine.”
The tipping point may have been reached recently when some bacteria strains evolved a resistance to colistin, an antibiotic of last resort.
In 2016, researchers in China found colistin-resistant E. coli bacteria in 20% of animals, 15% of raw meat samples and 1% cent of hospital patients that were sampled.
The colistin resistance gene (mcr-1) could easily be transferred among the different bacteria in the samples.
Malaysia was one of the first countries where scientists found colistin-resistant bacteria.
“Since the publication of our findings, mcr-1 gene has been found in many other countries,” said Associate Professor Dr Chan Kok Gan of University Malaya.
“This is a frightening scenario and the whole world should sit up and take action to prevent further abuse of antibiotics.”
If this resistance continues to spread, colistin will become less and less effective and we will eventually lose the “antibiotic of last resort”.
The colistin story also carries another lesson: resistance is being spread through the agricultural sector and the food chain.
In many countries, much of the antibiotics used (80% in the United States) are fed to animals to fatten them up and prevent or treat diseases.
Resistant bacteria builds up in the animals and are present in raw meat. From there, some bacteria are passed on to humans when they eat the meat.
In Malaysia, the Department of Veterinary Services in 2012 found that half of the domestic chickens tested had bacteria that were resistant to three types of antibiotics (ampicillin, sulphonamide, tetracycline), as cited in a memorandum by the Consumers’ Association of Penang.
The environment is another source of antibiotic resistance.
Residue and waste containing resistant bacteria flow from farms and medical institutions and contaminates soil, rivers and seas.
Some of the bacteria find their way to humans.
The European Union banned the use of antibiotics as growth promoters in animal feed in 2006, while the US started action to phase them out in 2013. In most developing countries, little action has so far been taken.
Hopefully that will start to change. Last month, on the eve of World Antibiotic Awareness Week (Nov 13-19), the World Health Organisation issued new guidelines on the use of antibiotics in food-producing animals.
A WHO-sponsored study found that actions restricting antibiotic use in animals reduced antibiotic-resistant bacteria in these animals by up to 39%.
WHO’s new guidelines include:
• An overall reduction in the use of all classes of medically important antibiotics in food-producing animals.
• Complete restriction of using these antibiotics for growth promotion and for disease prevention without diagnosis.
• A healthy animal should only receive antibiotics to prevent disease if it has been diagnosed in other animals in the same flock or herd or fish population.
• Antibiotics used in animals should be from the WHO list as “least important” to human health and not from “highest priority critically important”.
In 2015, Health Ministers attending the World Health Assembly adopted a Global Plan of Action on anti-microbial resistance, and they agreed that each country should prepare a national action plan by 2017.
Thus urgent, coordinated action is now needed. Since there are many sources of antibiotic resistance, the national effort must include not only the health authorities but also those responsible for agriculture and the environment.
The Health Ministry should control the spread of infections (including in hospitals), carry out surveillance of antibiotic resistance, introduce and implement regulations and guidelines on proper prescriptions as well as enforce ethical marketing of drugs and rational drug use.
The Agriculture Ministry should phase out inappropriate use of antibiotics for animals, especially for growth promotion, while the Environment Ministry should prevent resistant bacteria from contaminating soil, rivers and seas.
There should be campaigns raise to awareness of the dangers of wrongly using antibiotics and of demanding that their doctors give them antibiotics unnecessarily.
The medical profession should adhere to guidelines on the proper use of antibiotics, while drug companies should not push for maximum sales but instead advocate prudent use of their antibiotics in both the health or animal sectors.
These are the more obvious actions that need to be taken, immediately, to slow down the alarming rate of antibiotic resistance.
If we fail, it may well be “the end of modern medicine”, as the global health leaders and the scientists have warned us.
