Isn't the liquid more expensive? I've heard that some are opening the capsules if it even comes in capsule form anymore and measuring that out. Love Phillipa

> You can ask your doctor to prescribe dissolved Prozac. The standard version is 20 mg/5 mL. 5 mL is one teaspoon. With the oral solution, dose is proportional to the volume you swallow. To get exactly 8 mg Prozac, you would need to take 2 mL of the solution. 10 mg is 2.5 mL. And so on. 4 mg/mL is the concentration of the pediatric oral Prozac, but, I think it comes in generic forms now. That should be much cheaper.

> LarLarry, I appreciate all that information, although I'm not currently in the right state of mind to do the math myself :) The thing that I wanted to know mostly is whether anyone has had any experience with lower doses of prozac in regard to the OCD. I've read where a lot of people seem to feel that their depression is treated equally successfully with 5 or 10 mgs, but I need to know what effect the lower dosages will have on my ocd. Any info you could give would be greatly appreciated. I've heard many good things about you from Phillipa, and so far, she seems to be right. Thanks.....Paul

Paul, I can only speculate. I think you might very well have positive results at a lower dose. Yes, 5 or 10 or 15 mg/day might work, yet still avoid the adverse effects. I simply have not done such an experiment. If I must resort again to an SSRI, that would be my next experiment. To test the low-dose Prozac regime. I believe in it. I cannot predict the outcome with any certainty. It certainly could work, just as you imagine it might.

P.S. If you go with the liquid, I can help you with the dosing.

Larry,
Because of the extended half-life of prozac, is it possible to take one 20 mg. capsule every 4 days to get a 5 mg. dosage, or is that too bumpy of a ride? I have been taking 20 mgs. every other day to get ten per day, i hope i am doing the right thing...john

I don't know that rates are interpolatable down to zero. In other words, if half-life laws hold absolutely in lower dose realms. I just don't know. I wouldn't go below 10 every other day. If I wanted lower than that, I would use daily dosing.

You can take prozac 20mg every other day to get the same as 10mg a day. Strange though, when I used to do that, I always felt a little different on the days I skipped doses and didn't sleep as well either. For some strange reason the daily doses made a difference for me.

Not sure about low dose prozac for OCD. Try it and see. I think I actually developed more OCD symptoms at 20mg that weren't there at 10mg.
For daily dosing you can do the orange juice trick. Dump a 20mg capsule in orange juice, or water, stir it or shake it well, then drink 1/2 of it. Put the rest in the fridge. It will keep for at least a week. For the next dose, stir well again (prozac settles to the bottom) and drink.

Hi everyone
Fluoxetine (Prozac) comes as a once-weekly capsule: PROZAC WEEKLY. The only difference between normal fluoxetine and Prozac Weekly is that Prozac weekly caps are enteric coated (which causes a slight delay in release) and contain 90mg fluoxetine instead of the common 20mg. I imagine the enteric coat is supposed to reduce the risk of nausea.
http://www.rxlist.com/cgi/generic3/prozac_weekly.htm
Fluoxetine can only be taken once weekly after a patient has been stabilised on daily/alternate day fluoxetine for several weeks or more. Normal fluoxetine caps can also be taken weekly, you don't have to buy Prozac Weekly. A person taking 10mg fluoxetine per day (70mg per week) could attempt to switch to 60-80mg once weekly. Single weekly doses of fluoxetine > 90mg have not been studied.
Like Larry said, I think it's normally better to take fluoxetine more frequently. Large gaps between doses lead to troughs in the blood level, which may be a problem - it might reduce efficacy and allow withdrawal symptoms to emerge between doses. If a high dose of fluoxetine is taken once weekly, peak blood levels may be high, increasing the risk of side effects. Personally, I would not recommend taking fluoxetine once weekly. Alternate day dosing is just fine though.

I'm new to this thread. I was recently taken off of Lexapro 10mg qd because it seemed to have loss its effectiveness, prior med was Cymbalta (I won't even begin to talk about that stuff!!!) Anyway, the doctor put me on 20mg about a week ago and I feel so blah, tired and cranky. I am not motivated to do any of my normal activities. I suffer from depression, not severe except for during PMS times, the rest of the time is like a very mild rollercoaster. Any hints out there? Maybe 20mg q other day?...

i found that 10 mg prozac worked better for me for both mdd and ocd. more energizing; less apathy by far. less (er) GI side-effects.
my last ever p-doc (mr. NPD) did, once in a rare while, get a few things right: he said that there is much literature to support that 10 mg. works better for a sizeable number of folks. sorry, i no longer have any links.
if you happen to have any upper GI problems, avoid like the plague the liquid form, because plain or flavored ALL contain peppermint = very bad for GERD (reflux).

> Do you take name brand or generic Prozac?
in past, took brand mostly. last time, i switched to generic, and i found, as one other poster on this forum recently said, that generic prozac is one (perhaps the only one, imo), where you can switch, with no lessening of efficacy. BUT, you have to, imo, check out the particular maker of the generic. for instance, merk medco was not good (for me), while PAR pharmaceuticals was fine.

forgot to repeat in this thread that i must take only the tablet form (GI problems with gelatin in capsules).
also, fyi, the brand 10 mg. prozac tablet has recently stopped being made.

They only stopped making brand name Prozac in the 10 mg. TABLETS.
Best guess it was a $ issue - (the usual!) - most people being able to tolerate the 10 mg. capsules.

> LarHey Lar, I'm considering Prozac at 5 mg/day.
May I ask if this is in the dose range you're talking about?
Might low dose prozac take longer to reach a theapeutic effect than the normal 4-6 weeks, or possible have less potential for poopout?
Lastly, is there a specific reason you 'believe in' the low-dose Prozac regimen? Ed mentioned that 5 mg worked in the intial clinical trials.

Hi Saturn,
One of the initial clinical trials for fluoxetine examined the effectiveness of 5mg, 20mg and 40mg in the treatment of depressive illness. 354 patients were included in this trial. Effectiveness was assessed using the HAM-D rating scale. The trial lasted 6 weeks. In this trial, 5mg, 20mg and 40mg were all more effective than placebo. There was no evidence that the higher doses were more effective than 5mg.
The efficacy of 20mg fluoxetine has been studied in a greater number of patients than 5mg, which is why the manufacturer decided that 20mg would be the 'standard dose'.

> Hey Lar, I'm considering Prozac at 5 mg/day.
>
> May I ask if this is in the dose range you're talking about?Yes, right in around 5. The thing is, if you use a liquid form, i.e. a fluoxetine solution, you can precisely determine the dose, down to decimal points.
Even though the label on the pediatric solution might say 20 mg/5 mL, I betcha that you can assume that 20.0 mg is in each 5.0 mL. So, if you want to take 4.2 mg fluoxetine, you solve this equation:
X mL = (4.2 mg)(5.0 mL)/ 20.0 mg
X mL = 1.05 mLThe equation itself is derived by doing the cross-product on the ratios. 20.0 mg is to 5.0 mL as 4.2 mg is to X mL. The cross product gives (20 mg)(X mL) = (4.2 mg)(5.0 mL). Divide both sides by (20 mg), and you have isolated the variable you wish to determine the algebraic value for.
Ignoring the significant figures issue for a second, your challenge is in measuring out 1.05 mL exactly. You can calibrate an eye-dropper, and probably get very very close to that volume. Once you know how much drug is in one drop, you can change the dose by that increment. Moreover, if you get good at using an eyedropper, you can get very close to exactly half a drop. Even a quarter of a drop, if you learn how.
> Might low dose prozac take longer to reach a theapeutic effect than the normal 4-6 weeks, or possible have less potential for poopout?No, it would not take longer to reach therapeutic effect, if it is the right dose for that individual.
I believe there would be less potential for poopout, not more. Your body would not be escalating its detox mechanisms to get rid of the "toxin", if it was the right dose for you. At least, the detox mechanisms would be the minimum achievable for that drug.

> SatA low dose is perfect for some people, and a high dose is perfect for others. There is a threshold effect. If you're below the ideal dose, for your unique body, the only solution is to take more medication. For those people for whom 20 mg is not enough, the solution is to increase the dose. But, 20 mg is not the therapeutic dose, it is the *median* therapeutic dose. You have to realize that just as many people have a personal therapeutic dose that is less than 20, as there are people for whom it is more.

> LarThis is such an old post, don't know if you'll get it or not. Anyway, I've been on Prozac for 10yrs or so and it worked wonderfully for depression but caused a lot of inner agitation. Long story short..I'm tapering off and am down to 2.5mg every other day. I've been on 2.5mg every other day for 2wks and my mind is clearer than it has been for a long time. I'm more motivated etc. In your opinion do you think this will last or is it only because I still have so much prozac in my system. I would like to be able to take the 2.5mg every other day or even every day as long as it will keep depression away. Have you heard of anyone being able to continue on such a low dose of prozac for any period of time and staying depression free?
Thanks so much,
Karen

Hi Karen, I take 20mg every other day, so effectively 10mg daily. My sister used to take a 10mg dose once a week, so that would be approximate to what you're presently taking.
I think it has something to do with both the long half life of this particular drug AND just how responsive our individual bodies are to it. (Based not on any science but my experiences). Any more Prozac than what I'm on and I get really jittery and unable to calm down. At this dosage, my depression seems pretty much in control (I haven't been crying lately) and my obsessive thinking has vanished.
I'm just grateful when something works and doesn't mess me up with too many side effects. Or poops out on me.
take care

Agree with above as when new med given 20mg and felt great first day second day anxiety and third day panic. So I ditched it and the pdoc at the time said it was a dramtic reseponse and suggested I take it every third day. Didn't as wasn't depressed at time. But the first day was magnificent. And so true about the long half life something like 200 hours before all gone or five weeks? Could be wrong about the length Of thim. Phillipa
