Overzealous use of antibiotics can lead to resistant bacteria
Antibiotics have been used to fight bacterial infections for over . 70 years. Serious diseases such as tuberculosis or cholera, which a hundred years ago were fatal for humans , no longer pose the threat they once did.
But in many cases patients fail to use antibiotics properly. Antibiotics come in two categories ; wide-spectrum and narrow-spectrum.
Wide-spectrum antibiotics are effective against a large range of bacteria . Narrow-spectrum antibiotics . are used to fight specific types of bacteria.
Because of the widespread use of antibiotics,some bacteria have become resistant to them. They can no longer be. Treated with conventional medicines such as wide-spectrum antibiotics.
To prevent bacteria from becoming reslstant, antibiotics can only be obtained with a doctor’s prescription in most countries.
But that’s not the case everywhere. “In Spain,for example,they can be bought over the counter. Resistance there is very high ,”says Ursula Sellerberg of Germany’s Association of Pharmacists.
Antibiotics work soon after they have been taken. “In most cases, the patient is free of symptoms within a few hours ,“says Sellerberg. But if patients stop taking the medicine too soon,not all the bacteria may have been killed.
Sellerberg strongly advises patients to follow their course of treatment for as long as long as their doctor tells them to.
That will eliminate the chance of some bacteria surviving and becoming resistant,which would prevent others infected with those bacteria from being treated effectively with the same antibiotics.
