Understand when antibiotic medicines will work and when they will not work to treat an illness: Leave the habit of taking antibiotics every time you are sick. These drugs are effective in treating most bacterial infections, but they fail to fight against viral infections such as flu and cold. Sometimes, the cause of illness is difficult to understand, a majority of people get confused whether illness results from a bacteria or viruses. Consult your health care specialist if you are not sure.

Take exactly as prescribed: Follow your physician’s instructions while taking antibiotic drugs. The instructions may include how many times a day or for how long. Don’t stop the treatment if you start feeling better. A complete course is needed to kill all the harmful bacteria. If you do not complete the full course, it will add to the antibiotic resistant problem. An incomplete course of antibiotics will be able to remove only the vulnerable bacteria, which allows relatively resistant bacteria to grow vigorously.

Never take a pill without a doctor’s prescription: Antibiotics can be only purchased on the prescription of a doctor. However, if you haven’t completed the full course of that previously prescribed, you will try and take some of that medications the next time you get sick. You might give them to a family member who is sick. The problem with this practice is that the medicine might not be required to treat the illness, it might not be the right option to fight the bacteria in your body. All these practices can contribute to stronger strains of resistant germs.

Don’t take it if you have a virus: A prescription for antibiotics will not be effective if you have a cold or the flu. Don’t pressure your doctor to prescribe antibiotics for a virus. Instead, consult about ways to ease the symptoms of your virus illness.
