Hydroxyzine (Atarax) is contraindicated in early pregnancy and should NOT be used for panic attacks during this period
The FDA drug label explicitly states that hydroxyzine is contraindicated in early pregnancy, as it induced fetal abnormalities in animal studies at doses above the human therapeutic range, and adequate clinical data in humans are insufficient to establish safety 1.
Key Evidence Against Use in Pregnancy
FDA Drug Label Position
The official Atarax prescribing information clearly contraindicates hydroxyzine in early pregnancy due to:
- Documented fetal abnormalities in rats and mice at supratherapeutic doses
- Inadequate human safety data to establish early pregnancy safety 1
Guideline Recommendations
Multiple clinical guidelines specifically advise against hydroxyzine use during pregnancy:
- British urticaria guidelines (2007) explicitly state that "hydroxyzine is the only antihistamine to be specifically contraindicated during the early stages of pregnancy" in UK manufacturer guidance 2
- Guidelines recommend avoiding all antihistamines in pregnancy when possible, especially during the first trimester 2
- When antihistamine therapy is absolutely necessary, chlorphenamine is often chosen instead due to its longer safety record 2
Additional Safety Concerns
A case report documented neonatal withdrawal syndrome in an infant whose mother took 600 mg daily of hydroxyzine throughout pregnancy, suggesting high-dose use should be avoided 3. While a prospective controlled study of 53 women exposed to hydroxyzine during organogenesis found no increased teratogenic risk 4, this evidence is insufficient to override the FDA contraindication and guideline warnings.
Recommended Alternatives for Panic Attacks in Pregnancy
First-Line Pharmacologic Options
For panic disorder during pregnancy, evidence supports:
- SSRIs (particularly sertraline or paroxetine) - have the strongest safety data and efficacy for panic disorder 5, 6, 7
- SNRIs - can be considered as alternatives 7
- Tricyclic antidepressants - effective but with more side effects 7
Non-Pharmacologic First-Line Treatment
Cognitive-behavioral therapy (CBT) should be the preferred initial approach for panic disorder in pregnancy, as it has strong efficacy without fetal risk 6, 8, 7, 9. This avoids medication exposure entirely during the critical first trimester.
Benzodiazepines - Use With Caution
While benzodiazepines demonstrate short-term efficacy for panic disorder, they are not recommended as first-line treatment due to dependency concerns and should only be used for severe, acute symptoms under specialist supervision 7, 9.
Clinical Decision Algorithm
- Confirm pregnancy status before prescribing any anxiolytic
- Discontinue hydroxyzine immediately if patient is pregnant or planning pregnancy
- Initiate CBT as first-line treatment for panic disorder
- If pharmacotherapy is essential:
- Consider SSRIs (sertraline preferred) after shared decision-making discussion
- Weigh maternal benefit of treatment against small potential fetal risks
- Involve psychiatry and maternal-fetal medicine specialists
- Reserve benzodiazepines only for acute, severe panic attacks when other options have failed
Important Caveats
The evidence consistently shows that untreated severe anxiety and panic disorder can negatively impact pregnancy outcomes, including preterm birth and decreased breastfeeding initiation 5. However, this does not justify using contraindicated medications like hydroxyzine. The goal is adequate maternal symptom control using safer alternatives with established pregnancy safety profiles.
Patient concerns about medication use during pregnancy are valid and common 10, making shared decision-making and thorough counseling about risks and benefits essential for treatment adherence.
