I haven't taken either of those meds... sorry.
Gas and pain are common with IBS. The pain is mainly attributed to colon spasms and/or trapped gas. It also isn't uncommon to go from D to C with IBS. Many of us sit on the pot thinking we have to go but nothing comes out. Also, the feeling of not evacuating fully is common. I sometimes feel it crawl back up when I'm on the pot. Other times I'm like a garden hose. It is very frustrating. Either way you have it fiber is great for regularity. Beano and/or Gas-X are great for the gas and bloating.
I hope someone can help you with your meds.
