Lyrica and pregnancy
Ive been on lyrica and nuvigil fro fibro pain and fatigue, and just found out I'm pregnant. I'm just wondering if anyone else has taken either one of those while pregnant. I've stopped them for i was on only 50 mg of lyrica and about 100 of nuvigil. but I'm still worried, and i feel like I've been hit by a train once again, the pain is almost unbearable, i know my doc personally, have an appt. with him for the 12th. he just texted me and told me that in the mean time if my symptoms come back take them till he sees me at the least. i still dont feel like i should take it.
any feedback would be appreciated!

Very glad to help. Best wishes for a healthy pregnancy. Children are a blessing and for some of us, our only real treasure.
Congratulations.
50mg is low dose therapy. I've included information direct from the FDA below that talks about fetal abnormalities, but note that the dosages given at 3,000mg per day. The rat studies were given minimum doses at least 500mg / kg -- that's equivalent to giving a 120lb woman 25,000mg / day.
Ask your doctor's experience about giving pregabalin during pregnancy. Ask him about the risks. Don't let him hand wave your concerns away. All treatment is based on informed consent -- that means you need information, from the prescriber, before you can consent to treatment.
Best wishes.
Lyrica USE IN SPECIFIC POPULATIONS
Pregnancy
Pregnancy Category C. Increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity, including lethality, growth retardation, and nervous and reproductive system functional impairment, were observed in the offspring of rats and rabbits given pregabalin during pregnancy, at doses that produced plasma pregabalin exposures (AUC) ≥5 times human exposure at the maximum recommended dose (MRD) of 600 mg/day.
When pregnant rats were given pregabalin (500, 1250, or 2500 mg/kg) orally throughout the period of organogenesis, incidences of specific skull alterations attributed to abnormally advanced ossification (premature fusion of the jugal and nasal sutures) were increased at ≥1250 mg/kg, and incidences of skeletal variations and retarded ossification were increased at all doses. Fetal body weights were decreased at the highest dose. The low dose in this study was associated with a plasma exposure (AUC) approximately 17 times human exposure at the MRD of 600 mg/day. A no-effect dose for rat embryo-fetal developmental toxicity was not established.
When pregnant rabbits were given Lyrica (250, 500, or 1250 mg/kg) orally throughout the period of organogenesis, decreased fetal body weight and increased incidences of skeletal malformations, visceral variations, and retarded ossification were observed at the highest dose. The no-effect dose for developmental toxicity in rabbits (500 mg/kg) was associated with a plasma exposure approximately 16 times human exposure at the MRD.
In a study in which female rats were dosed with Lyrica (50, 100, 250, 1250, or 2500 mg/kg) throughout gestation and lactation, offspring growth was reduced at ≥ 100 mg/kg and offspring survival was decreased at ≥250 mg/kg. The effect on offspring survival was pronounced at doses ≥1250 mg/kg, with 100% mortality in high-dose litters. When offspring were tested as adults, neurobehavioral abnormalities (decreased auditory startle responding) were observed at ≥250 mg/kg and reproductive impairment (decreased fertility and litter size) was seen at 1250 mg/kg. The no-effect dose for pre- and postnatal developmental toxicity in rats (50 mg/kg) produced a plasma exposure approximately 2 times human exposure at the MRD.
There are no adequate and well-controlled studies in pregnant women. Use Lyrica during pregnancy only if the potential benefit justifies the potential risk to the fetus.
To provide information regarding the effects of in utero exposure to Lyrica, physicians are advised to recommend that pregnant patients taking Lyrica enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry. This can be done by calling the toll free number 1-888-233-2334, and must be done by patients themselves. Information on the registry can also be found at the website http://www.aedpregnancyregistry.org/.
Labor and Delivery
The effects of Lyrica on labor and delivery in pregnant women are unknown. In the prenatal-postnatal study in rats, pregabalin prolonged gestation and induced dystocia at exposures ≥50 times the mean human exposure (AUC (0–24) of 123 µg∙hr/mL) at the maximum recommended clinical dose of 600 mg/day.
Nursing Mothers
It is not known if pregabalin is excreted in human milk; it is, however, present in the milk of rats. Because many drugs are excreted in human milk, and because of the potential for tumorigenicity shown for pregabalin in animal studies, decide whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
The safety and efficacy of pregabalin in pediatric patients have not been established.
In studies in which pregabalin (50 to 500 mg/kg) was orally administered to young rats from early in the postnatal period (Postnatal Day 7) through sexual maturity, neurobehavioral abnormalities (deficits in learning and memory, altered locomotor activity, decreased auditory startle responding and habituation) and reproductive impairment (delayed sexual maturation and decreased fertility in males and females) were observed at doses ≥50 mg/kg. The neurobehavioral changes of acoustic startle persisted at ≥250 mg/kg and locomotor activity and water maze performance at ≥500 mg/kg in animals tested after cessation of dosing and, thus, were considered to represent long-term effects. The low effect dose for developmental neurotoxicity and reproductive impairment in juvenile rats (50 mg/kg) was associated with a plasma pregabalin exposure (AUC) approximately equal to human exposure at the maximum recommended dose of 600 mg/day. A no-effect dose was not established.
