Mr. B (mentioned in the previous question) returns to the clinic in 4 weeks with a 50% improvement on the AD? And no of the medication. He still is considerably depressed; but his energy has improved slightly. You should:

1) Increase the AD

2) Continue on the same dose and review in 4 weeks

3) Add an adjunct, a 2nd AD or mood stabilizer

4) Change to another AD class.

5) Review history from patient and family to see if a stressor has been overlooked.
