A. depends on the infection it is important to follow the instructions opinion advice and medicines course given by your doctor for the problem . they are safe if given by registered medical practitioner. do not take medicines not prescribed by the doctor . take a follow up in few days if it is not improving for need of treatment modification or any lab / radiological investigations.
