B) 1-2 weeks.
C) 3-4 weeks.
D) Results vary and depend on the individual's response.

Answer 1

It typically takes 3-4 weeks to start seeing results from tricyclic antidepressants. Immediate side effects may occur, but elevation in mood takes longer due to the necessary physiological changes.

Step-by-step explanation:

Tricyclic antidepressants like imipramine are commonly used for treating major depression. When starting a tricyclic antidepressant, it is normally not expected to see immediate effects. Instead, the medication must be taken consistently over a period of time before its therapeutic benefits are observed. Based on what is known about these medications, it typically takes 3-4 weeks to start seeing an elevation in mood for patients with depression. This is due to the required time for physiological changes in neurotransmitter levels and neural adaptations to take effect. This longer onset of action contrasts with some initial side effects, such as sleepiness and light-headedness, which can occur soon after taking the drug.
