Immunity cannot be improved overnight. There is no medicine which can directly improve your immunity just by taking a small course of it. Rather immunity is an ongoing process which is gained by diet, lifestyle and support of immuno modulating medicines.
If you want to boost your immunity, you have to target the most affected system first. For example, if you are getting frequent infections in your respiratory track, then you have to manage it by increasing the health conditions of your lungs and upper respiratory track.

Antibiotics are to be used only after a diagnostic test which is called as culture and sensitivity test. In modern clinical practice, it has been seen in multiple cases that most of the doctors just prescribe an antibiotic without culture test. Such a prescription can lead to drug abuse (antibiotic abuse). Frequent use of such unauthorised antibiotics is going to make you resistant to such antibiotics.
Antibiotics not only depress the growth of infection, but also they can cause adverse drug reactions. Always use antibiotics carefully so as to avoid damage to the immune system.
