my son is on these meds. Pristiq, My son thsts theses meds. Pritiq, Lithium Carb, Olanzapine. Hes been noticing and myself that he has acid reflux and gets hickups bad, plus when he lays down at nite the acid reflux seems to be worse, im not sure if he has swelling of the throat, but i,m concerned because he seems to get chocked and can,t swollow sometimes when eatn. Is this a big concern, sholud he let his doctor know. Now when he was on someother meds in the past, he was throwing up in his sleep and was inhaleing or you,d call it vomiting and it got in his lungs one time, and they collasped. That was back in 2010 when he was on seriqiul he no longer takes that. so the new 3 meds he,s on now is what i,m worried about. please give me any addvice. Thank You concernerd mom.
