Usage of antibiotics for a wrong reason or in an inadequate manner can be harmful. Wrong usage of antibiotics tend to change the bacteria such that it develops the ability to defeat the antibiotics which are actually designed to kill them, as a result of which they continue to survive and multiply.

Hence, the microorganisms develop resistance and become difficult to be treated by the antibiotics which have become ineffective. So, please DO NOT take antibiotics casually. Consume antibiotics only if prescribed by the clinician and follow the protocol in which it has been prescribed. Even if your symptoms have subsided, take the antibiotics till the last dose prescribed by the clinician. 

Educate your loved ones about the adequate usage of antibiotics and stay healthy!
