Here are some guidelines from the American Academy of Family Physicians on when antibiotics may be needed:

• Most colds and flus are caused by viruses, and won't respond to antibiotics.
• Bronchitis and coughs are often caused by viruses, but if they persist, there may also be a bacterial infection that will respond to antibiotics.
• While sore throats are usually caused by viruses, strep throat is a bacterial infection that requires antibiotic treatment.
• Some ear infections are caused by viruses, and some by bacteria. Your doctor will decide if an antibiotic can help.
• Sinus infections are usually bacterial, and need treatment with antibiotics.
