Let’s start with do antibiotics work for all infections? The simple answer is no. Antibiotics work against bacterial infections and not virus infections. So when you see your doctor, find out what kind of infection you have because unfortunately some doctors will prescribe antibiotics either way even if they will do nothing against a virus.
Most sore throats do not need antibiotics as they are usually caused by viruses. However, the exception here is strep throat. Strep throat is a bacterial infection and will need antibiotics. Best to go to your doctor to properly diagnose this condition.
Cold & Flu
Many people go to the doctor because they have a cold or the flu, and I would say that more often than not, they are prescribed antibiotics. Unfortunately antibiotics will not help in fighting a cold. The cold and the flu are both viruses but the issue is that antibiotics treat bacteria so will have little to no affect. Next time you are prescribed antibiotics for a cold, ask your doctor what exactly the antibiotics will do to help. Antibiotics are generally not good for our bodies, so only take then if you really need to.
Scraps And Cuts
For most scraps or cuts from grass, dirt or metal, you will not need antibiotics. However there are certain cases where you will need them or a tetanus shot. This is especially the case if you have a skin condition. Make sure you get your injury looked at by a professional. So if you are playing golf and you cut yourself on the golf course for example, you will more likely need a tetanus shot (if you haven’t had one in the last few years) then antibiotics. But just to be safe, see a doctor and get their professional suggestion.
Many ear infections are caused by a bacterial infection and generally need antibiotics for treatment. However, just to complicate things, some ear infections are virus caused. Best thing to do is see your doctor for a diagnoses.
