Cytochrome P450 inhibitors
Make sure to check the MAOI#Interactions
Some CYP450 inhibitors are also MAOIs.
Cytochrome P450 inhibitors inhibit the ability of the human body to break down certain substances, potentially increasing the amount of time a substance is active in the body.
In some cases, this inhibition of how substances are broken down in the body can lead to dangerous adverse effects. Under some conditions, this can be fatal.
