Antibiotics are medications that are prescribed to treat bacterial infections. They either slow down the growth of the infectious organisms or kill them. An antibiotic’s efficacy depends on various factors like host defense mechanism, the infection’s location and properties of the antibiotic. Antibiotics can be administered orally, through injections or by topical application of creams and lotions. Oral antibiotics are prescribed to treat infections of the respiratory tract and digestive tract and urinary tract infections, etc. They are used in diseases to treat diseases like pneumonia and tuberculosis. Topical antibiotics are prescribed for mild to moderate skin infection and acne. Once prescribed, it is important to complete the course of antibiotics as recommended by the doctor. Non-compliance to the course of antibiotics makes the disease causing bacteria resistant to those antibiotics, rendering them ineffective.
