Doctors are recommending that patients on Ozempic or similar diabetes and weight loss drugs use condoms instead of relying solely upon hormonal birth control because of the risk of unintended pregnancy and the possible consequences of the drugs on developing fetuses.

Some female patients on Ozempic and similar drugs, known as GLP-1s, have reported that they’ve become pregnant while on the medication despite using hormonal contraceptives or having a previous diagnosis of infertility, a phenomenon colloquially called the “Ozempic baby boom.”
