Is Gabapentin (Neurontin) safe during pregnancy?
What the FDA-approved label for Gabapentin (Neurontin) actually states in its Pregnancy Risk Summary — not a secondhand verdict. The decision is one to make with your prescriber.
What the label’s pregnancy summary says
The label states there are no adequate data on the developmental risks of gabapentin in pregnant women. Animal studies (mice, rats, rabbits) showed developmental toxicity — increased fetal skeletal/visceral abnormalities and increased embryofetal mortality — at doses similar to or lower than clinical doses, though the clinical significance is unknown. Because gabapentin is an antiepileptic drug, the label directs pregnant patients to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry (1-888-233-2334). It does not declare the drug safe or unsafe in pregnancy; discuss use with your prescriber.
Frequently asked questions
Is Gabapentin safe to take during pregnancy?
The honest answer is uncertainty: the label does not have enough pregnancy data to call Gabapentin safe or unsafe (summary above). That is a "decide with your prescriber" situation, weighing your condition against the unknown, not a green or red light. The one universal rule: do not start or stop a medication in pregnancy without medical advice — an untreated condition can carry its own risk to a pregnancy.
What does the FDA label say about Gabapentin in pregnancy?
The summary above is transcribed from the label's Pregnancy Risk Summary (§8.1). Since 2015 FDA labels replaced the old A/B/C/D/X letter categories with a narrative that describes what human and animal data actually show, which is what you are reading here — not a single letter grade.
Is Gabapentin safe while breastfeeding?
That is a separate question the label answers in a different section (§8.2, Lactation), and it does not always match the pregnancy verdict. This page covers pregnancy only. For breastfeeding, ask your prescriber or pharmacist, or check the NIH LactMed database, which summarizes the drug-in-breast-milk evidence.

The pregnancy information is transcribed from the drug’s FDA-approved label (§8.1) and mirrors what the label states — “insufficient data” is never rounded up to “safe.” This is general reference information, not medical advice. Whether to take any medication in pregnancy is a decision for you and your prescriber; do not start or stop a drug on your own, because an untreated condition can also carry risk.
