I don't know about pregnancy but the hydroxine I take (pamoate) has had some I believe to be unknown side effects and most them are wonderful. I used to be alcoholic, for a 12 pack of beer a day for about (im 50) 30. Most of my adult life, off and on and when i wasn't a drinking, I was bulimic. I always craved either beer or food or something-you know, always anxiuonious , but I am a totally different person.. I didn't stop drinking from this drug..II used ANTABUSE. bUT things are easier now. I don't see my self as an alcoholic now. As long as I take my meds, I am trying to get used to it and others are too. Those who don't want to accept me can go away and Im ok with that. For anyone suffering from overeating should ask their doctor and seriously about this drug. Another bad effect, you wont know your hungry until your body tells you it is, so make sure you set a time regularly to have food with you and you will make it healtghy because you dont crave any certain food. Usually if something, like icecream or steak sounds good, I eat just a little to enjoy the food and dont want anymore than a little. Its only time for relatively new drug is found to have these effects.. I am using the generic name because thats what i get and sisnce its generic it should be like one of those 4 dollar drugs at walmart and I dont want to think i am any pharmocuetical for prifit.. This drug could rid the world of obesity, if you can handle tghe side effects. And make sure you are around a bathroom or use pads, or are willing to pop a squat because you dont know you have to pee unless your bladder is full i mean you are going to pee your pants. I hope a lot of people read this. I maty clean up my misspellings but I am going to try to get the word out.
