ANTI-BIOTICS

WHAT ARE ANTI-BIOTICS
Antibiotics are strong medicines used for treating infections, including life-threatening infectious diseases. But antibiotics can cause more harm than good when they aren't used the right way. You can protect yourself and your family by knowing when you should use antibiotics and when you should not.
MECHANISM OF ACTION
No. Antibiotics only work against infections caused by bacteria, fungus and by certain parasites. They don't work against any infections caused by viruses. Viruses cause colds, the flu and most coughs and sore throats.
BACTERIA RESISTENCE
Usually antibiotics kill bacteria or stop them from growing. However, some bacteria have become resistant to specific antibiotics. This means that the antibiotics no longer work against them. Bacteria become resistant more quickly when antibiotics are used too often or are not used correctly (such as not taking a full course of antibiotics as prescribed by your doctor).Resistant bacteria sometimes can be treated with different antibiotics to which the bacteria have not yet become resistant. These medicines may have to be given intravenously (through a vein) in a hospital. A few kinds of resistant bacteria are untreatable.

NEED OF ANTIBIOTICS
Colds and flu. Viruses cause these illnesses. They can't be cured with antibiotics.
Cough or bronchitis. Viruses almost always cause these. However, if you have a problem with your lungs or an illness that lasts a long time, bacteria may actually be the cause. Your doctor may decide to try using an antibiotic.
Sore throat. Most sore throats are caused by viruses and don't need antibiotics. However, strep throat is caused by bacteria. Your doctor can determine if you have strep throat and can prescribe an antibiotic.
Ear infections. There are several types of ear infections. Antibiotics are used for some (but not all) ear infections.
Sinus infections. Antibiotics are often used to treat sinus infections. However, a runny nose and yellow or green mucus do not necessarily mean you need an antibiotic
