@jackiet the OxyContin is a time release pill (your gray one). I take the Percocet 10 mg which is part Tylenol. I’ve taken that for years without any trouble. But then two years ago there was a shortage so I was switched to the oxycodone 10 mg – the pink pill KVT brand it was fine but then there was a shortage on that and they switched me to a white pill different brand and I had trouble. I looked up the lactose and definitely there is more lactose in the OxyContin time released one like 70 mg compared to 44. And the pink one there’s no listing to see. There’s something called Roxycodone - that is the one without lactose. I haven’t tried it. It’s an oral suspension and maybe I should look into that. I generally take a half a pill every four hours and later in the day or at night I can stop and switch to Tylenol. But like I said, taking lactose pills, kind of solves a problem and the pharmacist told me to take it with food and not on an empty stomach. I had my genetic testing done and I inherited my lactose intolerance from both parents. It’s in my DNA from both sides. Not only that, but I seem to have a casein intolerance as well. Sometimes I will buy lactose free cheese and I’ll still get a stomachache. That’s when I learned that I was casein intolerant. I’m very good about eating a clean diet and when I get a stomach ache it’s usually some medication that doesn’t agree with me and they put lactose in it. Good luck!
