I would ask the manufacturer, since they actually know the process.
Years ago I was taking some tablet that was painted with some kind of substance designed to slow the release of the medication within. Since it passed through my digestive system so fast, I was missing out on its therapeutic benefit. After check with my doctor and the manufacturer, I found it was okay to rinsed them under a faucet until most of the paint came off.
The thing is, we tend to revere doctors and put our trust in them. But we shouldn't. I mean, when it comes to meds, all they know is what the pharma sales rep tells them, and this is often bullshit, as demonstrated by so many drugs that have been taken off the market over the last few decades.
I'm just saying, before you put something in your body, ask questions about what it is. It just makes sense.
