First separate a clear medication success from a partial or burdensome response. If an antidepressant has robustly improved life, continues to work, and produces no meaningful side effects, Palmer's simplest rule is to keep taking it. If symptoms remain, or effects such as weight gain, sexual dysfunction, slowing, or emotional numbness are significant, begin with education rather than abrupt action. Clarify goals and review the wider context: metabolic health, weight, diabetes risk, diet, alcohol or marijuana use, sleep, and exercise. Those answers determine which intervention is relevant; there is no universal replacement. Bring the benefit-side-effect record and contextual assessment to the prescriber, agree on one or more monitored changes, and reassess. The framework supports shared decision-making and explicitly does not justify stopping medication without clinical guidance.
Origin
Palmer offered this decision rule when Hala Taha asked what listeners already taking prescribed antidepressants should do with the brain energy theory.
Core principles
- 01A medication that robustly helps without side effects may be worth continuing
- 02Partial benefit and side effects justify a structured review
- 03Education should precede treatment changes
- 04Mental symptoms should be assessed alongside metabolic and lifestyle factors
- 05Medication decisions belong in a qualified care relationship
How to run it
- 1
Rate the benefit
Describe how much the antidepressant has improved symptoms, function, and quality of life, and whether that benefit has persisted. Distinguish a robust response from a medication that only kind of works.
Pro tip Use concrete before-and-after examples rather than a vague impression.
Watch out A temporary good or bad day is not a reliable medication verdict.
- 2
Inventory the burden
Record side effects such as weight gain, sexual dysfunction, emotional numbness, or feeling slowed down. Include effects that matter to quality of life even if they are not medically dangerous.
Pro tip Note timing and severity so the prescriber can interpret the pattern.
Watch out Do not conceal side effects because the medication helped another symptom.
- 3
Apply the first branch
If benefit is robust and ongoing with no meaningful side effects, continuing the current treatment is the simplest option. If benefit is incomplete or burden is material, move to education and reassessment.
Watch out This branch is a discussion aid, not permission to change a prescription independently.
- 4
Assess the wider system
Review metabolic health, weight, diabetes risk, comfort eating, alcohol or marijuana use, sleep, and exercise. Use the answers to identify contributors and intervention options beyond a medication-only view.
Pro tip Define what better mental and physical health would look like for you.
Watch out Lifestyle contributors do not mean the illness is a failure of discipline.
- 5
Make a shared plan
Discuss benefits, side effects, goals, and contextual factors with the prescribing clinician. Agree on a matched intervention and how it will be monitored.
Pro tip Bring a concise written record to the appointment.
Watch out Abrupt antidepressant discontinuation can be harmful.
- 6
Review and iterate
At the agreed review point, compare symptoms, function, side effects, and metabolic health with the baseline. Continue, adjust, or seek additional expertise based on the evidence.
Pro tip Change one variable at a time when clinically appropriate and when learning which factor helped matters.
Watch out Worsening symptoms or suicidality require urgent professional support.
In the wild
A patient reports that an antidepressant restored daily function, the improvement has persisted, and they have no meaningful side effects. They document the benefit and review it with their prescriber rather than changing treatment solely because a new theory or diet is receiving attention.
→ A working treatment is preserved instead of disrupted by novelty.
A patient has some symptom relief but also weight gain, emotional numbness, poor sleep, and nightly marijuana use. They educate themselves, record symptoms and side effects, and bring the full picture to their prescriber. Together they choose and monitor a clinically appropriate next step rather than stopping medication abruptly.
→ The treatment conversation expands from a binary medication choice to a monitored whole-person plan.
Common mistakes
Stopping medication abruptly
The framework is for structured review with the prescriber, not unsupervised discontinuation or dose changes.
Counting partial relief as complete success
Persistent symptoms and meaningful side effects deserve explicit assessment even when the medication helps somewhat.
Blaming every symptom on medication
Sleep, substances, metabolic health, diet, physical illness, and the underlying disorder may also contribute and need assessment.
Is it for you?
Best for
People already taking an antidepressant who want a clearer conversation with their prescribing clinician about results and side effects.
Not ideal for
Abrupt self-directed medication changes, emergencies, or severe symptoms requiring urgent professional care.
