Frequently Asked Questions

Is it true that antibiotics only work if you have an infection that is caused by bacteria?

When you are sick, antibiotics will only help you to feel better if your illness is caused by a bacteria. If you have a virus, an antibiotic won't make you feel better because antibiotics don't kill viruses.

Keep in mind that 90% of colds and flu - and the sore throats, aches and pains, chills, runny noses, watery eyes, and dry coughs that go with them - are caused by viruses. It is also important to know that the average adult gets two to three colds and flus in a year and that symptoms will usually last for up to 10 days.

You should consult a doctor if:

  • Your illness lasts for more than one week
  • Symptoms suddenly become worse
  • You have a high, persistent fever
  • You have thick, coloured discharge from your nose that lasts longer than two weeks
  • You have sinus pain, an earache or a toothache
  • You have a cough that gets worse and persists for more than two weeks

If uncertain about any of these symptoms, always consult your physician.
