Answer:To be effective and do the job they were intended to do, antibiotics must be taken for the full course of therapy prescribed by your doctor. If you stop the medication early—even if you are feeling better—some bacteria may survive and could come back even stronger. The bacteria that survived can then become resistant to the antibiotic, worsen the infection you already have, and make it harder to treat. Be sure you finish taking all the medication on the schedule prescribed by your doctor. If you are experiencing any side effects from the medication, contact your doctor and discuss the matter. There may be a different medication that can be prescribed for you.
