Lactose in pills


Senior Member
I'd been wondering about this because of my response to certain medications. Re: hydrocortisone, which I've been trying for the past week, I had pretty miraculous results for the first 3 days, which seemed to have petered out. I'm aware this is a common pattern steroids, but given my extreme food sensitivities, I had also wondered if lactose fillers can affect how we respond to medications?

I'm definitely sensitive to lactose, but not allergic. Is it more likely one would notice some GI distress as opposed to a filler actively negating the medication's effects?
