yes CBT and Medications can be used at the same time. medicaitons do n ot change a persons behaviors and how they feel about their behaviors. medications for mental disorders (anti depressants, anti psychotics..) makes it so that a persons physical symptoms are under control by changing how the reseptors and neurons and chemicals in the brain work together.

but medication can not control whether a person understands right from wrong, whether they understand how to use problem solving...

example a person with depression may have a chemical problem in their brain where the neurons and receptors are working too fast\firing off electrical impulses too fast. (a physical health problem) then a psychiatrist prescribes the antidepressant lithium (example what gets prescribed for each person is idividualized).... the lithium slows down the neurons and receptors to where they are working\firing off electrical impulses slower.

but even on medication a person can still choose whether they self injure, commit crimes or otherwise make bad choices in their lives. example a person on lithium can still choose whether they pay their rent or impulse spend their checks, resulting in their life problems of evictions, bill paying stress, relationship problems.....

CBT teaches problem solving tools a person can use in any situation in their life to better their life, better their reactions to stress, better at taking care of their physical and emotional needs, better at at taking care of their basic food clothing and shelter needs. CBT does all this and more through a structured program of looking at the problems in your life, setting goals to solve those problems and then using the skills taught in CBT classes/ sessions to solve those goals...

example (using an example everyone can relate to and hopefully is non triggering ) a person on medication is having financial problems...

problem financial problems from impulse buying.
goal fix financial problems by ....

learning how to write up a budget
learning how to pay bills first, buy necessities then later what one wants.
learning how balance a checking account.
open a checking account,
open a savings account.

documenting each step and reporting back to therapist how each step worked out and if changes to the plan need to be done. when client has accomplished their goals or completed the structured classes therapy a future follow up session is scheduled and client it done with therapy or done with therapy on that issue.
