Can any prescription medicine and any supplements at any dose be the cause to contract something?

Sure, but...: Everything in life can be the cause of something or the effect of something. That is life. In the grand scheme of the timelines of our lives, any little thing we do or don't do, can affect the future. We haven't perfected time travel so we cannot affect the past. Most medications, supplements, or other chemicals affect us in a dose-dependent way, meaning a tiny amount may cause nothing noticeable.
