    Many women spend heaps out of pocket a month to get their hands on drugs like Semaglutide (Ozempic and Wegovy) or Tirzepatide (Mounjaro). The benefits of these drugs, which are part of a new class called GLP-1 receptor agonists (Glucagon-like peptide-1), include significant and rapid weight loss, blood sugar control, and improved life quality.

    On the flip side, the desire for rapid weight loss and better blood sugar control also comes with an unexpected cost. Many women living with obesity who take oral contraceptives are unaware that these drugs – especially Mounjaro – can interfere with the absorption of birth control pills and how well they work, making an unintended pregnancy more likely.

    One of the ways that drugs like Mounjaro work is by delaying the time that it takes for food to move from the stomach to the small intestine. Although data is still evolving, it is believed that this process – delayed gastric emptying – may affect the absorption of birth control pills.
    Also sometimes vomiting, which is a common side effect of these types of drugs, also affects the pills' ability to prevent pregnancy.
