Domperidone, a gastrointestinal medication, is often prescribed off-label to breastfeeding women in Canada to help increase their milk supply. Many have described it as a “miracle drug” that has helped them feed their babies. But, as a CBC investigation has found, some also believe that withdrawal after they stopped taking the drug left them in severe psychological distress — and even, in some cases, suicidal. Today, Tara Carman — a senior reporter with CBC’s national investigative unit — walks us through her team’s findings. **UPDATE** - An earlier version of this episode said 120 million prescriptions for domperidone were filled in 2020, based on data from Health Canada. After publication of this story, Health Canada corrected their publicly available data to reflect that 1.7 million prescriptions were filled in that year, representing around 120 million tablets. This episode now reflects that change.
