Have you seen a GI or just a PCP? My GI had to look up the side effects of the meds I was taking because I was getting some weird ones. So they might not know but they should look it up if you ask.
As far as long term side effects of Aciphex, this is what I found. Some of these side effects include high blood pressure, heart attack, chest pain, irregular heartbeat, allergic reaction, weight gain, depression, glaucoma, abnormal vision and bladder infections. Although these are considered the most common long-term effects of this drug, they only affect a small number of users.
