Effects

Pregnancy
Use only when the benefit to the mother justifies the possible risk to the fetus.
Mother
May cause side effects and dose changes may be needed during pregnancy; do not stop or change without prescriber advice.
Baby
May cross the placenta. Reports include possible CNS effects, limb deformities, and developmental delay, but cause is not proven.

Trimester Notes

1st Trimester
Limited human data. Official labeling does not show a proven birth-defect risk, but use only if benefits outweigh risks.
2nd Trimester
Use only if needed and prescribed. No adequate, well-controlled studies in pregnant women.
3rd Trimester
FDA labeling and reviews note possible neonatal withdrawal or anticholinergic symptoms with late-pregnancy exposure; newborn monitoring may be needed.

Risk-Benefit Note

For depression and some pain conditions, untreated illness can also harm mother and pregnancy. Continue or change treatment only with prescriber guidance.
