Yes, You Can Safely Resume Sertraline After Missing One Day
Simply take your regular dose as soon as you remember and continue with your normal schedule. Missing a single day of sertraline is not dangerous and does not require any special dosing adjustments 1.
What To Do Right Now
- Take your missed dose immediately if you just remembered
- If it's almost time for your next scheduled dose (within a few hours), skip the missed dose and take your next regular dose at the usual time
- Do not take two doses at the same time to make up for the missed dose 1
- Continue your regular dosing schedule going forward
Why This Is Safe
Sertraline has a 24-hour elimination half-life 2, meaning it takes a full day for half the drug to leave your body. This relatively long half-life provides a buffer when doses are missed. After missing one day, you still have medication in your system, though at lower levels.
The FDA label explicitly addresses this scenario and confirms that resuming your regular dose after a single missed day is appropriate 1.
What You Might Experience
While sertraline is associated with discontinuation syndrome (to a lesser extent than paroxetine but more than fluoxetine) 2, missing a single dose typically causes minimal to no symptoms. Discontinuation symptoms are characterized by:
- Dizziness, fatigue, lethargy
- Headaches, nausea
- Anxiety, irritability, agitation
- Sensory disturbances or "electric shock-like sensations" 1
These symptoms typically occur with acute discontinuation or multiple missed doses 2, not after missing just one day.
Important Caveats
Do not make a habit of missing doses. Research shows that approximately 30% of patients on shorter-acting SSRIs like sertraline experience dosing lapses of 2 or more consecutive days, which can result in clinically relevant deterioration of mental status 3.
If you frequently miss doses, consider:
- Setting daily reminders on your phone
- Using a pill organizer
- Taking your medication at the same time each day (either morning or evening) 1
- Discussing adherence challenges with your healthcare provider
When to Contact Your Provider
Contact your healthcare provider if you:
- Experience significant withdrawal symptoms after the missed dose
- Frequently miss doses (this may indicate need for a different medication or delivery system)
- Notice worsening of your original symptoms (depression, anxiety, etc.)
The key message: Missing one day is not a medical emergency. Simply resume your normal dose and schedule without doubling up.
