Dependence means your body becomes used to the medicine. You may feel unwell if the medicine is reduced or stopped suddenly.

Addiction is when a person feels unable to control use of a medicine despite harm or negative effects.

Tolerance

Tolerance means the medicine may become less effective over time, leading some people to feel they need higher doses.
