It is generally higher than you see with ssris. This paper reports the odds of dropping out due to intolerance for lots of antidepressants vs placebo (page 154 of appendix). By comparison, the or in our study was 4.4.

GRATEFUL to @nihr.bsky.social for funding this work and @oxhealthbrc.bsky.social for support.
Pramipexole is clearly not a first line treatment for depression, but these results demonstrate that it can be a useful option for our most treatment-resistant patients! 6/6

TRANSPARENCY: There are challenges to using pramipexole: 20% stopped pramipexole due to side effects vs 5% placebo. Most common: nausea, headache, dizziness, sleep problems. 5/6

HYPOTHESIS: We targeted dopamine D2/3 receptors with pramipexole instead of the usual serotonergic approach. Dopamine is crucial for reward/pleasure - and anhedonia (can't feel pleasure) is often what persists even after other depression symptoms improve. 4/6

Background: About 30% of our patients don't respond to first-line antidepressants. We recruited people with chronic depression (median 8.5 years) who had tried 3-4 medications without success. These are the patients we struggle to help most. 3/6

FINDINGS: In our randomized controlled trial (n=150), patients receiving pramipexole showed:
• 6.4-point reduction in QIDS scores vs 2.4 for placebo (p<0.0001)
• 44% response rate vs 16% placebo
• 28% remission vs 8% placebo Effect size d=0.87 - this is substantial! 2/6
• 6.4-point reduction in QIDS scores vs 2.4 for placebo (p<0.0001)
• 44% response rate vs 16% placebo
