That doesn’t seem like the common side effects of these types of medication, but it is certainly possible what he is experiencing is just that.
From my experience with my diagnosed brother,
The basics are what help the most:
Exercise, diet and a healthy daily routine.
If the digestive problems are bad enough that your husband needs to seek out relief, I would suggest that he start putting together a strict diet that consists of pre-planned meals.
That’s a really difficult kind of lifestyle change for most, so it’s usually best to try to break it down into smaller, easier stages.
My brother had problems with acid reflux and frequent vomiting for a long time. The obvious suspect in that situation was his dependency on fast food (which made up the vast majority of his diet). Super high fat, sodium and preservatives were clearly not going to help, and were probably the cause of the problem.
But it took a lot of effort, time and a change in lifestyle to get away from fast food.
Eventually, he moved back in with our mom and began eating mostly home-cooked meals with things like preservatives almost eliminated and fat and sodium reduced significantly. He recovered in a matter of weeks and hasn’t had a problem with it since.
That was a big revelation to me, because my brother had been very certain that his medication was causing these problems. The same for weight gain, lack of energy, etc…
Now, it’s apparent that his medication does play a role in these issues, but a healthy diet, daily exercise and a reasonable sleep schedule have made massive improvements in every category.
That’s why I know refer to those things as “doing the basics”. Not because they’re easy, but because they can ease, or fix all kinds of problems.
