I was on symbicort for about 12 days. 2puffs in the am and 2 in the pm. I wasn't on it for asthma, but my primary question is how long does it take to leave my system?

Also, does whey protein powder have any sort of interaction with symbicort? It's 100% Whey (whey protein isolates) & other supplements are in it like lactase and aminogen, whey protein microfractions like Alpha-lactalbumin, {igG}, etc. & Glutamine and BCAAs. I know protein in itself isn't harmful when used with the inhaler. It's all of the other ingredients in the protein powder I'm concerned about. I haven't the slightest clue if any of the above mentioned ingredients would interact with Symbicort so if anyone has any info they can provide I'd greatly appreciate it.
