General notes

When meeting with any health professional, it is important for you to share the following information:

  • Your medical history and allergies (medication, food, or other);
  • If you smoke, are pregnant, are planning a pregnancy, or are breastfeeding;
  • The names of all the medications you take, whether you take them regularly or once in a while, including over-the-counter medications, vitamins, and natural health products.


It is also strongly recommended that you keep an up-to-date list of all the medications you take and carry it with you at all times. This could be useful if you have to see a health professional or need emergency care.

Keep all your medications out of the reach of children and pets and return any unused or expired medications to the pharmacy for proper disposal.
