It takes a lot of decision making for someone to decide to go on meds. It also takes a lot of adjustment, tweaking, and acclimating to get to the point where meds are helpful. This is a decision which nobody makes lightly, and it’s a serious decision- meds which are brain altering can literally change personality.
So there are probably plenty of people out there who should be on meds but aren’t- and that’s a valid call to make. I am close with people who are on meds, should be on meds but aren’t, and could go either way (and generally have not elected to start). It’s such a weighty decision that you can assume that those who are on meds are taking them with great care and under the guidance of medical professionals- and many who should be on meds are not necessarily under any guidance. If done well, meds can be amazing for many people, and certainly, there are risks- but there are much bigger risks than going out with someone who is on doctor-controlled medication. (I would recommend only going out with someone who has been on the same medication successfully for a reasonably long period of time- different meds can wreak havoc on a person if they’re wrong and it can take a while to hit upon the right med at the right dose.)
tl;dr- yes, I’d go out with someone on meds. And a good chunk of the above argument came from someone very close to me in her decision to go on meds even as she was concerned about shidduchim.
