About Directly Observed Therapy (DOT)

  • Pulmonary Tuberculosis (TB) is a serious, contagious disease. You will need to take several antibiotics for 6 months or longer. It takes a long time to treat TB. If you stop your antibiotics too soon you will most likely get sick again. Because the germs have grown stronger, the TB antibiotics taken before may not work.

  • Directly Observed Therapy (DOT) is the best way to treat TB. DOT means a DOT Worker from Peel Health will meet with you twice a week. The DOT Worker will provide your TB antibiotics. A Public Health Nurse will call you to arrange a visit to give you information about TB and to introduce your DOT Worker to you.
