Femara (letrozole) is metabolized in liver by cytochrome p450 system. Astaxanthin says "use cautiously w drugs metabolized by liver's cytochrome p450 enzyme system; does this mean don't use astaxanthin w femara (letrozole)?

1 doctor agrees

In brief: Not necesarilly but

Virtually all drugs are metabolized by cytochrome p450 enzymes.
Astaxanthin can stimulate these, so it could lead to lower blood levels of "certain drugs" according to http://www.Naturalmedicinejournal.Com/article_content.Asp?Article=293. I no of no evidence that Femara (letrozole) is one of the drugs it interacts with. Small amounts of astaxanthin are unlikely to have much effect.Ask the doc who prescribed it.

In brief: Not necessarily

The key word is caution.
All rx drugs require physician management, and benefits need to far outweigh risks. So, talk with your physician about that, and you'll be able to feel confident about those mutual choices.
