No. Ivermectin should not be used during pregnancy since safety has not been established. The US file still prints Pregnancy Category C. Mice, rats, and rabbits showed teratogenicity (cleft palate; clubbed forepaws in rabbits) at 0.2, 8.1, and 4.5 times the maximum recommended human dose of 200 mcg/kg on a mg/m2/day basis, at or near maternotoxic doses. Panel.

Are there adequate studies in pregnant women?

No. The label says there are no adequate and well-controlled studies in pregnant women. The close is categorical: should not be used during pregnancy.

Mass-campaign anecdotes from other countries are not this US sentence. Do not write 3 mg as a travel souvenir in the first trimester because a poster looked clean.

If treatment must wait, who owns Strongyloides in the meantime?

The obstetric and ID pair. Intestinal strongyloidiasis can become a dissemination problem when steroids start. That is not a nightstand 3 mg decision.

Tell the obstetric chart about endemic years before anyone writes prednisone. Repeat and immune questions: repeat scan.

Did fertility studies in rats look clean?

No adverse effects on fertility in rats at repeated doses up to 3 times the maximum recommended human dose of 200 mcg/kg on a mg/m2/day basis. That is a rat fertility line, not a pregnancy green light.

Do not quote the fertility sentence to override the pregnancy stop. They are different rooms.

Does a West African travel year change the pregnancy sentence?

Travel history matters for Loa loa assessment when someone warrants ivermectin for any reason. Pregnancy does not cancel that geography question. It also does not create a home 3 mg exception.

Loa detail lives on the Loa loa scan. This URL stays on the pregnancy stop.

Does ivermectin show up in milk?

Yes, in low concentrations. Treatment of mothers who intend to breast-feed should only be undertaken when the risk of delayed treatment to the mother outweighs the possible risk to the newborn.

That is a delay-versus-newborn sentence, not a forum yes. Ask the clinician who owns the strongyloides plan. This scan will not invent a pumping clock.

What did the animal work actually show?

Teratogenic in mice, rats, and rabbits at repeated doses of 0.2, 8.1, and 4.5 times the maximum recommended human dose of 200 mcg/kg (mg/m2/day). Cleft palate in all three species. Clubbed forepaws in rabbits.

Those effects sat at or near doses that were maternotoxic. The file then says ivermectin does not appear to be selectively fetotoxic. That clause does not open a casual pregnancy line.

Board thread

Answers follow the U.S. Stromectol label.

Freya J., Lawrence Park I am breastfeeding. Pump and dump after 3 mg?

Board reply

Ivermectin is excreted in human milk in low concentrations. The label frames a risk-of-delay versus newborn talk. It does not print a pump-and-dump clock. Ask the clinician who would write the 200 mcg/kg day.

Maren P., Davisville Can Stromectol 3 mg be written in pregnancy?

Board reply

The US file says it should not be used during pregnancy because safety has not been established. Category C. There are no adequate well-controlled studies in pregnant women.

Luis C., Brockton I am 28 weeks and stool-positive. Start 200 mcg/kg tonight?

Board reply

Do not start a home count. Call the obstetric and ID pair. The labelled strongyloides maths is about 200 mcg/kg, but pregnancy is a stop until they own the delay versus the infection.
