Since bacteria are living organisms, they are constantly changing in an ongoing effort to resist the drugs that can kill them. When adults and children use antibiotics incorrectly, bacteria adapt and become resistant, and can become an antibiotic-resistant infection. Never save the medication to treat yourself or others later.
Antibiotics are powerful drugs used to treat certain illnesses.
However, antibiotics do not cure everything, and unnecessary antibiotics can even be harmful. There are two main types of germs that cause most infections. These are viruses and bacteria. Antibiotics cannot kill viruses. Antibiotics do kill specific bacteria.
