How to Restart Sertraline 100mg

When restarting sertraline 100mg, begin with a lower dose of 25-50mg daily for 1-2 weeks before increasing to the target dose of 100mg to minimize side effects and optimize tolerability. 1, 2

Recommended Restart Protocol

Step 1: Initial Restart Dose

  • Start with 25-50mg once daily (morning or evening) for the first 1-2 weeks 1, 2
  • Take at the same time each day to maintain consistent blood levels 3
  • Monitor for initial side effects which may include gastrointestinal disturbances (nausea, diarrhea) 4

Step 2: Dose Titration

  • After 1-2 weeks at the lower dose, increase to 100mg once daily if the initial dose is well tolerated 1
  • Titrate gradually to minimize adverse effects such as anxiety, agitation, or gastrointestinal symptoms 1
  • If significant side effects occur during titration, consider extending the time at the lower dose before increasing 5

Step 3: Maintenance

  • Once at 100mg daily, continue at this dose as it is considered an effective therapeutic dose for most patients 2
  • Full therapeutic effect may take 3-4 weeks to achieve 6
  • Monitor for continued efficacy and tolerability 4

Important Considerations

Potential Side Effects During Restart

  • Initial anxiety or agitation may occur when restarting, particularly if dose is increased too rapidly 5
  • Gastrointestinal effects (nausea, diarrhea) are common but usually transient 4
  • Sexual dysfunction may occur but often decreases with continued treatment 4

Special Precautions

  • Avoid abrupt discontinuation as this may lead to discontinuation syndrome (dizziness, fatigue, sensory disturbances, anxiety, irritability) 1
  • If previously on other serotonergic medications, ensure adequate washout period to avoid serotonin syndrome 1
  • Do not combine with MAOIs due to risk of serotonin syndrome 1

Dosing Flexibility

  • Sertraline can be administered at any time of day 2
  • Food does not significantly affect absorption 3
  • No dose adjustment is typically needed for elderly patients 2

Clinical Pearls

  • Rapid dose escalation may increase risk of behavioral activation or side effects 5
  • The therapeutic effect of sertraline is not necessarily enhanced by doses higher than 100mg for most patients 6
  • If side effects occur at 100mg, consider returning to a lower dose (50mg) which may still be effective 6
  • Steady state plasma levels are typically reached after approximately 7 days of consistent dosing 3
