I have been on Klonopin for about 7 years. I have tried numerous times to wean my self off because doctors tried to wean me off within days, which was unrealistic. Now i'm at 5 months pregnant and STILL on the medication. I worry everyday what this could do, especially since the doctors at my AWFUL hospital seem to have no care about it when i tell them!! I have no insurance so my prenatal care alone has been like a "pull up and get looked at, not talked to and go"! I have managed to take a .5 mg pill and break it into fours though to take daily a piece of it and on work days i take 1/2 of the .5 mg pill.
I would also like to address the fact that when i have tried to get off the medication i have been treated like a drug dependant crack head! They are not remembering that i take this for agorophobia! As soon as i mention the meds to doctors, they automatically attack! This dis order has caused me more pain than i can say for many years!! As for my pregnancy, i need help.. i would of course like an answer from someone saying it's going to be fine, but please help!!
Also, if you are anticipating needing this only for situations like public speaking you may want to speak with your doctor about a beta-blocker. Beta-blockers can be a good substitute for benzos that are taken for such situations and preliminary studies show beta blockers to be safer than benzodiazepines during pregnancy.
Klonopin is a Class D drug which means evidence exists to suggest that "may" harm the fetus of a pregnant women. However, drugs that are taken once-in-awhile typically don't pose the same risk as those taken on a regular basis BUT every case is different and it depends on when the drug is taken (1st, 2nd, 3rd trimester). In any case, this is something you should discuss w/ your doctor to get some statically information on so you can make a well-informed decision. Also bare in mind, that panic feelings can be amplified during pregnancy so while you may anticipate needing 4 mg of Klonopin during your whole pregnancy, that may not be the case in reality.
