Best Anxiety Medication for Pregnancy
Sertraline is the safest and most evidence-based pharmacologic treatment for anxiety in pregnancy, with the strongest safety profile and efficacy data among SSRIs. 1
First-Line Pharmacologic Treatment
Sertraline should be initiated at 25-50 mg daily as the preferred SSRI for anxiety during pregnancy. 2, 3 This recommendation is based on:
- Sertraline has the most favorable risk-benefit profile among SSRIs, with mixed and generally unsubstantiated associations with negative outcomes when controlled for maternal depression and associated factors 1
- It demonstrates efficacy for panic disorder and anxiety with minimal fetal risk 3
- Sertraline can be safely continued during breastfeeding due to very low breast milk concentrations 1
Alternative First-Line Options
If sertraline is not tolerated or contraindicated:
- Citalopram represents an acceptable alternative, with similarly mixed evidence regarding adverse outcomes that remains unsubstantiated when properly controlled 1
- Low-dose imipramine or clomipramine may be considered for pure panic disorder 3
- Venlafaxine (SNRI) appears favorable for anxiety treatment in pregnancy 3
Medications to Avoid
Paroxetine should be avoided in pregnancy due to:
- FDA pregnancy category D classification for concerns about congenital cardiac malformations 4
- Strongest association with negative outcomes including significant malformations 1
Fluoxetine should also be avoided, as it has the strongest association with negative outcomes alongside paroxetine 1
Critical Safety Considerations
Neonatal Complications
All SSRIs carry risk of neonatal adaptation syndrome when used in the third trimester 4, 5:
- Symptoms include crying, irritability, tremors, poor feeding, respiratory distress, hypoglycemia, and seizures 4
- Onset occurs within hours to days after birth, typically resolving within 1-2 weeks 4
- Arrange early follow-up after hospital discharge for monitoring 4
Persistent Pulmonary Hypertension of the Newborn (PPHN)
- Late pregnancy SSRI exposure carries a number needed to harm of 286-351 for PPHN 4
- PPHN occurs in 1-2 per 1000 live births and is associated with substantial neonatal morbidity and mortality 5
Other Pregnancy Risks
- SSRIs may increase risk of preterm delivery compared to untreated depression 4
- Possible associations with lower Apgar scores, though high-quality evidence is lacking 4
Risk-Benefit Analysis
The risk of untreated anxiety/depression during pregnancy outweighs the risks of SSRI treatment when pharmacotherapy is indicated. 6, 7
Untreated anxiety is associated with:
- Premature birth 4
- Decreased breastfeeding initiation 4
- Maternal morbidity including hypertension and preeclampsia 8
- Increased risk of postpartum depression 8
- Suicide attempts and relapse when treatment is discontinued 8
Treatment Algorithm
- Start with sertraline 25-50 mg daily as first-line pharmacologic treatment 2, 3, 1
- Use the lowest effective dose to minimize fetal exposure 4, 5
- Continue treatment throughout pregnancy rather than discontinuing, as withdrawal increases relapse risk 8
- Monitor the neonate closely in the first week of life for signs of neonatal adaptation syndrome 4, 5
- Continue sertraline during breastfeeding if needed, as it has favorable lactation safety 1
Adjunctive Treatment
Cognitive Behavioral Therapy (CBT) should be offered concurrently, as it demonstrates large effect sizes with minimal side effects and represents first-line treatment for anxiety disorders in pregnancy 2, 7
Common Pitfalls to Avoid
- Do not abruptly discontinue SSRIs due to pregnancy—this increases relapse risk and may harm the mother-infant dyad 4
- Do not withhold adequate treatment based solely on pregnancy status when anxiety is clinically significant 6, 7
- Do not use paroxetine or fluoxetine as first-line agents given their stronger associations with adverse outcomes 1
- Do not fail to arrange early neonatal follow-up after delivery when SSRIs were used in the third trimester 4
