REM rebound is most commonly associated with withdrawal from which type of agents?

• A. Alcohol
• B. Heavy hypnotics
• C. Certain antidepressants
• D. Stimulants

Answer: (C)

REM rebound happens when the brain compensates for REM sleep suppression that occurred during drug use. When a drug markedly reduces REM sleep, stopping it can lead to a rebound surge in REM activity as sleep architecture rebalances, often with more vivid dreams or nightmares. Many antidepressants strongly suppress REM sleep while they’re being taken, including various TCAs, SSRIs, and SNRIs. When these medications are withdrawn, the suppression lifts and the brain can overcompensate, producing a pronounced REM rebound. This pattern is a well-documented feature in sleep pharmacology and helps explain why patients stopping antidepressants frequently report disrupted sleep with vivid dreaming. Alcohol and heavy hypnotics can also cause REM rebound on withdrawal, but antidepressants are particularly associated with this rebound because their REM-suppressing effects are a common and consistent part of their sleep impact. Stimulants, by contrast, tend to disrupt sleep differently and don’t typically produce a strong REM rebound upon withdrawal.
