LactRx is sponsored by MotherToBaby, the Leading Resource on Exposures during Pregnancy and Breastfeeding

BRENTWOOD, TN – The non-profit Organization of Teratology Information Specialists (OTIS), through its public-facing service known as MotherToBaby, launches LactRx, a free app providing current information on the use of medications, vaccines, diagnostic agents & drugs of misuse during breastfeeding. The LactRx app provides easy access to the LactMed database, a resource from the National Library of Medicine (NLM).

In 2019 the NLM announced that the LactMed app was being discontinued. The announcement prompted a discussion between Phil Anderson, PharmD, FASHP, UC San Diego clinical professor and author of LactMed and Christina Chambers, PhD, MPH, MotherToBaby Past President and Mommy’s Milk: Human Milk Biorepository Program Director, about MotherToBaby sponsoring a new app for LactMed. “This was a hugely popular resource with millions of hits,” said Chambers.  Because of this, she saw it as an opportunity for MotherToBaby to help build and host a new app with all of the LactMed information.

In October of 2021, the idea was brought to the leadership of the Organization of Teratology Information Specialists (OTIS), the professional non-profit that provides the MotherToBaby no-cost service. Development commenced and LactRx was born.

“The NLM made the decision to continue supporting web access to LactMed, and to discontinue support for its app. However, in Dr. Anderson’s experience, the app was a very popular and a user-friendly mode of access to the data,” explained Chambers. “In collaboration with NLM, MotherToBaby was given permission to create the LactRx app and, thus, to expand ease of access to this critical information for providers and the public worldwide.”

Information presented in the LactRx app is not intended to be a substitute for professional judgment. Users should consult personal healthcare providers for breastfeeding advice related to their particular situation.

MotherToBaby also works closely with the NLM to contribute bilingual (English/Spanish) evidence-based fact sheets regarding medications, vaccines, diseases, herbal supplements, occupational exposures and more during pregnancy and breastfeeding.

MotherToBaby traditionally provides information on exposures before and during a pregnancy as well as breastfeeding through its no-cost helpline 866-626-6847, texting service 855-999-3525 and website www.MotherToBaby.org, where the public can live chat or e-mail an expert.

World-Renowned UC San Diego Epidemiologist Leads Groundbreaking Study

SAN DIEGO, CA – Recruitment is underway for a groundbreaking new study on the treatment of lupus during pregnancy.  The observational research, led by world-renowned UC San Diego epidemiologist Christina Chambers, PhD, MPH, is the first of its kind for the non-profit MotherToBaby, a CDC-recommended organization that provides evidence-based information on medications, diseases, vaccines, herbal supplements and more during pregnancy and breastfeeding. 

The study will recruit 400 pregnant people over a five-year period to evaluate use of the lupus drug Benlysta® (belimumab) in pregnancy. Benlysta® is used to treat the most common type of lupus, systemic lupus erythematosus (SLE), as well as lupus nephritis. Currently, there is limited information on the drug’s use in pregnancy.

The study will be MotherToBaby’s first to focus on a treatment specifically for lupus, and participants will be enrolled into the MotherToBaby Pregnancy Studies research program. Chambers, who is the lead investigator for MotherToBaby Pregnancy Studies, Co-Director of the Center for Better Beginnings, and Chief of the Environmental Science and Health Division in the UC San Diego Department of Pediatrics, noted that, “lupus can raise the risk of pregnancy complications, so it’s important for both the mom and her developing baby that this condition be well-managed during pregnancy. So, when treatments for lupus like belimumab are available, we want to do our best to gather information about those pregnancies where this medication has been used.”

The study is enrolling pregnant and recently pregnant people with exposure to Benlysta® and will provide critical information on the use of this medication during pregnancy. Participants will not be asked to change any part of their health care routine, including medications, nor will they be asked to travel.
