DESCRIPTION
The metabolism of Domperidone can be decreased when combined with Acetaminophen.
EXTENDED DESCRIPTION
Due to competition for the CYP1A2 binding sites, substrates of this enzyme may be metabolized at a lower rate. When CYP1A2 substrates are coadministered, this may increase the serum concentration of either or both drug, increasing the risk of toxicity and adverse effects.
Here's the information I found on the drug interaction tracker, but I can only purchase domperidone as an antiemetic (in my country, it's the only over-the-counter option). If taken simultaneously, could it cause my SN regimen to fail? Should I consider discontinuing the pain medication?
