koali777 Posted March 17, 2012 Share Posted March 17, 2012 I remember when I was on Geodon before, about 3 hours before my next dose (I was prescribed once a day), I'd get dizzy, headache, vertigo, anxious, not myself. I assumed it was withdrawals. Now I have it on Latuda. I can't just keep taking it every 21 hours. I see my pdoc in 5 days but wondering if anyone else experiences this. I feel like I'm having withdrawals...not psychosis, but withdrawals. Is there any way to help it? Like not have caffeine in the morning, etc? I don't take the Adderall every day.

Swamp56 Posted March 17, 2012 Share Posted March 17, 2012 I get the same exact thing! About 3.5 hours after I take my first dose of Geodon (or about 0-2 hours before I take my second dose) during the day I start to have anxiety, mental cloudiness, shakiness, and an inability to focus on anything.

koali777 Posted March 18, 2012 Author Share Posted March 18, 2012 Glad to know it's not just me! It says, at least for Latuda, that the half life is 18 hours (I don't remember Geodon's). And Latuda is supposed to be special in that you just have to take it once a day. I wonder if anyone else may know, for either of them. Link to comment Share on other sites More sharing options...

And Latuda is supposed to be special in that you just have to take it once a day. I wonder if anyone else may know, for either of them. I think that you are having the common misunderstanding of half-life and meds. I assume that you are taking your meds every day. If so, the blood level of them build up until they reach a steady state. Look at it this way ... let's assume for the sake of argument that the half life is 12 hours and that all the med ends up in your blood. You take your first dose of, say, 40 mg. After 12 hours there will be 20 mg in your blood. After 12 more hours there will be 10 mg in your blood (1/2 * 20). Then you take your second dose. Now you have 40 mg + 10 mg = 50 mg in your blood. After 12 more hours you will have 1/2 * 50 = 25 mg and after 24 hours, you will have 1/2 * 25 mg = 12.5 mg. And so on. Do you see how it builds up? I haven't shown how it reaches steady state, but that is irrelavant to my point. This is a way over-simplified example to demonstrate that the Latuda is building up in your blood. It is not true that after 18 hours you have only 1/2 of 40 mg in your blood, unless of course, you took just one pill. Link to comment Share on other sites More sharing options...
koali777 Posted March 18, 2012 Author Share Posted March 18, 2012 Thank you. I know that stuff already actually, but was being lazy in my reply before. I was forced to take a class that had to do with it (and since my job involves helping people with math, we see the mock little half life problems a lot, although in that setting, comprehending it isn't really a big deal). I was more worried about anecdotal evidence than anything. My question was whether or not others felt this way close to med time. Geodon and Latuda affect me very similarly, and they are the only two this happened with. Thank you for the information anyway though. Link to comment Share on other sites More sharing options...
