Antibiotic Drugs Dose and Side Effects

Antibiotics can save lives by fighting bacterial infections. Antibiotics are among the most frequently prescribed medications in modern medicine. Antibiotics cure disease by killing or injuring bacteria. Antibiotics may be informally defined as the subgroup of anti-infectives that are derived from bacterial sources and are used to treat bacterial infections. Today many different types of antibiotics are available, and they fight infection in several ways. Some antibiotics dissolve the membrane of just bacterial cells. Others affect protein-building or DNA-copying machinery that is specific to bacteria.  The drug kills most of the bacteria but there are a few individual bacteria that happen to carry a gene that allows them to survive the onslaught of antibiotic.  Different families of antibiotics have different ways of killing bacteria. Remember, antibiotics can only kill bacteria, so they’re not effective against viruses like the flu or common cold. Taking antibiotics when you have a virus may even hurt you, because it hurts your resident microbes.
