From the Guidelines

Most sedating SSRIs are typically Paroxetine (Paxil) and Fluoxetine (Prozac), as they are often associated with significant sedation, especially at higher doses [ 1 ].

Most Sedating SSRIs

  • Paroxetine (Paxil) - often associated with significant sedation, especially at higher doses (above 20mg) [ 1 ].
  • Fluoxetine (Prozac) - can cause sedation, particularly in the initial stages of treatment or at higher doses (above 40mg) [ 1 ].
  • Sertraline (Zoloft) - may cause sedation, though generally less than paroxetine, and more commonly at higher doses (above 100mg) [ 1 ].

Least Sedating SSRIs

  • Citalopram (Celexa) - generally considered to have a low sedation profile, making it a good option for patients sensitive to sedating effects [ 1 ].
  • Fluvoxamine (Luvox) - tends to be less sedating compared to other SSRIs, though it can still cause sedation in some individuals, particularly at higher doses (above 100mg) [ 1 ]. It's crucial to remember that these rankings are general and can vary significantly between individuals [ 1 ]. The sedating effects of SSRIs can also be influenced by the dose, duration of treatment, and individual patient factors [ 1 ]. Always consult with a healthcare provider to determine the best SSRI for your specific needs.

From the Research

Sedating Effects of SSRIs

  • The sedating effects of SSRIs can vary between individual medications, with some being more sedating than others 2.
  • Paroxetine is noted to be more sedating and constipating in some patients, possibly due to its anticholinergic activity 2.
  • In contrast, other SSRIs such as fluoxetine, sertraline, and fluvoxamine are not associated with significant sedation 3.

Comparison of SSRIs

  • A review of SSRIs found that escitalopram was more effective than other SSRIs, including fluoxetine, citalopram, sertraline, paroxetine, and fluvoxamine, in terms of response rate, remission rate, and withdrawal rate 4.
  • The same review found that escitalopram had a lower withdrawal rate due to any cause, suggesting it may be better tolerated than other SSRIs 4.
  • Another study found that fluoxetine may provide a more rapid onset of therapeutic effect and is suitable for long-term maintenance therapy 5.

Least Sedating SSRIs

  • Fluoxetine is noted to have a faster onset of action and is suitable for long-term maintenance therapy, with no significant sedating effects 5.
  • Sertraline and fluvoxamine are also not associated with significant sedation, making them potential options for patients who are sensitive to sedating effects 3.
  • Escitalopram is noted to be more effective than other SSRIs, but its sedating effects are not specifically mentioned in the available evidence 4.

Most Sedating SSRIs

  • Paroxetine is the most sedating SSRI, due to its anticholinergic activity 2.
  • Other SSRIs, such as fluoxetine, sertraline, and fluvoxamine, are not associated with significant sedation, making paroxetine the most sedating option 3.
