Prozac half life

Common Questions and Answers about Prozac half life


Avatar n tn I continued to take the prozac and on my sisth week i broke out into hives from head to toe. there is so much confusing information on the half life of prozac. some info says 5 days others say months. I have now been onsteroids for 2 weeks and am continuing to have major hives. When will this end?
Avatar n tn George, The main risk of premature discontinuation of treatment with Prozac may be a recurrence of whatever psychiatric disorder the Prozac was being treated with. Prozac has a long half-life, and thus a low risk of "withdrawal symptoms".
Avatar m tn Prozac isn't known as much for withdrawal problems as the shorter half-life meds, and since you've been on it for such a short time it should be easy to quit. but going back through the dosage increases is still a good idea, as has been suggested to you.
Avatar f tn Well, by now you have probably talked to your doctor. In general missing one dose of Prozac is OK because of its long half life... but it is also true that I can't advise people about specific questions since I don't know them.
691920 tn?1252103061 Prozac's long half-life makes the issue of med compliance a little less of a big deal, hence the approval for depressed teenagers. It varies depending on each person's metabolism, but usually anywhere from 3 to 8 weeks you should feel it working. Also, That really long half-life means it takes forever to wean yourself off of Prozac. Best wishes!
Avatar n tn Usually the higher the dosage and longer you have taken the medication, the wosre and longer the side effects can be. Celexa has a relitivly long half life, thus it may be a few days off the medication before you feel any withdrawl effects. Then again, not every one that stops an SSRI gets withdrawl side effects. I know that I get prety nasty withdrawl anytime I switch medications. Some people don't. In most cases the withdrawl will subside in 2 to 4 weeks.
Avatar n tn Paxil is a clone of Prozac but with a shorter half-life. Prozac leaves the body more slowly than Paxil. Perhaps this site (social audit site) would help to explain it, its one of many sites but at a quick guess it will probably give you a lead to answering your question fairly quickly :) There's tons of info on the net (and I mean professional experts' information - the internet harbours both good and bad sites).
Avatar m tn This would be unusual for Prozac, since unlike the other ssris and the snris it has a long half life in the body. After only 21/2 weeks it's still pretty active in your body, whereas all the other short half life ones leave in a matter of hours. Yet you are describing the classic withdrawal symptoms those of us on the short half life ssris get. Maybe there's something in the interaction of the two meds -- maybe you should have waited longer for the Prozac to dissipate. I don't know.
Avatar n tn Vicki, Prozac has a very long half-life(last a long time in your body) and is generally the easiest SSRI to taper. You may discuss with your physician decreasing your dose to 10 mg for a few weeks before stopping it. The ativan should be tapered under the direct physician supervision as withdrawal can be life threatening depending on the dose and frequency. Sweating, grinding your teeth and feeling in a fog can be related to Prozac.
484508 tn?1290014144 serotonin build up occurs with Prozac, more that other drugs because the half life is so long. My query is about whether in reintroduction to the drug can create some minor immediate changes. Some physicians say yes, curious as to others experiences.I do not appreciate patronizing answers,bro.
1636357 tn?1300258094 Bad move, I know, but I longer have health insurance, hence the reason I stopped taking it. I was fine for a couple of weeks, as Prozac had a long half-life. The the brain zaps began...and still continue. My question is this: Is it possible that I may have brain zaps indefinitely? They are seriously driving me mad and I am at my wits end...I don't know what to do. I don't want to be a slave to this medication.
Avatar n tn This experience has put me off the idea of drugs. I am going to taper off in half increments for a week unless you can convince me prozac freakout is normal. i had most of the mental side effects listed as serious and worried about arrythmias. If it were not for radical impression challenging I probably would have lost it. Help, I have heard that most psychs. think you are nutz if you report this.
Avatar f tn Cocaine (benzoylmethylecgonine) for example is basically a norepinephrine, dopamine and serotonin reuptake inhibitor but we can feel it's action really quickly (apart the fact that it is most of the time snorted which makes it way more bioavaible) and it haves a short half-life. Ritalin works pretty much in the same way like you will feel the effect 30 to 1 hour after taking the drug. I am very happy that you have found, what seems to me, be a good doctor.
601528 tn?1224085098 I am on prozac and have been for about 6 months....This last week I have been very manic with ALOT of paranoia and anger. Could this be the prozac or would it have happened by now?
Avatar f tn As far as I'm aware Prozac is the most stimulating of the SSRIs. It also has the longest half life and is supposed to be the easiest to quit taking. If your problem is just anxiety I would try something else first. I find Zoloft to be a bit stimulating for me. Lexapro was very neutral and Paxil was very sedating. But we are each different so you may like Prozac.
527657 tn?1214055450 Paxil and all the other ssris other than Prozac have a very short half life, meaning they leave the body very quickly, some, like Paxil, in a matter of hours. That's believed to be the reason for the intense withdrawals.
Avatar f tn Interestingly, one of the ways you can minimize withdrawal is by slowing integrating Prozac in place of the Celexa because of it's half life. Good luck. Oh, you are not a drug addict. Anti-depressants are not "addictive" in that way.
Avatar f tn I would recommend that you add to your doctor to prescribe a short course of the anti-anxiety drug, Klonopin. That should help you get back on track if what you are experiencing are side effects or some other anxiety. You have already received some good advice about psychotherapy.
Avatar n tn Whereas, with all the other ssris, they have a very short half life, meaning they leave the body very quickly, in a matter of hours. It is believed this is one reason the body has such a hard time adapting to their absence, and withdrawal begins even before you're done tapering off them. Your psychiatrist is the person to discuss this with, but psychiatrists, including, I'm sure, Dr. Gould here, will tell you Prozac doesn't have the same withdrawal problems as other ssris.
Avatar n tn Dear Val Prozac is a medication with a long half life and so it is not necessary to taper the dose before stopping it. It can be stoppped abruptly with out experiencing any withdrawal symptoms. Medications such as SSRI,s (Serotonin Specific Reuptake Inhibitors) like zoloft and paxil and Benzodiazepines such as klonopin,xanax were shown to be effective in the treatment of panic disorder.
603726 tn?1223923260 This is especially true of Fluoxotine because it has a very long half life. Much longer than some other SSRI's. Basicaly, that means it takes longer to build up to theraputic levels, and it also takes longer to wash from the system should you ever choose to stop. Do expect to get a few side effects. Almost everyone does. If the side effects become very severe, then call you doctor. By in large most people tolerate this drug fairly well. You shouldn't have a problem. Good luck and remember..
Avatar f tn It is not as bad in regards to withdrawal symptoms compared to other anti-depressants because of its long pharmacological half-life, when tapering off and gradually discontinuing it. Do you have any alternative options after Prozac? Have you gone for therapy or counselling perhaps? This might be something to consider, if you haven't or if you stopped going, you should consider returning. I cannot imagine what the pain you're going through, feels like.
347397 tn?1196461633 I couldn't stand the annoying side effects of the Lexapro, so I asked her if I could try Prozac since it was the last thing I remember being on that didn't have a negative effect on me. Well I've been on it a week and a half, and I'm feeling better, but still having surges of anxiety, especially in the mornings. Sometimes it is worse than others. I find myself worrying excessively about everything in life, unable to enjoy things I used to, and not wanting to go out and do things.
Avatar n tn I recently stopped taking Prozac after having been on it for about a year and a half. It worked great, and in August I stopped. Today its October 15 and I feel like death and I believe I need to start again. Is there concern about how soon I am taking it again? Is there a problem with taking it for longer than a year? Nothing can be worse than how I feel but if the risks are high I would consider some natural way of fighting this.How worried should I be?
Avatar n tn In doing more research, however, I came to realize that it's not anxiety so much as withdrawal symptoms. Prozac has a really long half life, so withdrawal symptoms don't usually show up for a while (like more than a week). I've been reading Peter Breggin's book YOUR DRUGS MIGHT BE YOUR PROBLEM and have been finding it amazingly helpful.
Avatar n tn Additionally, my doctor just recently perscribed me Prozac. I'm hestitant because I have always live a lovely life untill now. Will the prozac trully help my OCD? Will it help me get off the xanax? Should 1 mg xanax be a worry for me? My doctor reassured me that I'm in good hands and when the times comes he will wean me off the xanax. He believes that the prozac will enable me to have the right mental outlook in life, which will make getting off xanax easier.
Avatar f tn First of all, you shouldn't just stop taking antidepressants without discussing it with your doctor. Fortunately, you weren't on the Prozac long enough and you were at a very low dose, so you didn't experience the nasty effects of going cold turkey off these types of meds. Prozac can take anywhere from 4-6 weeks to reach "steady state" in your body. That is the point at which it will begin to help you.
Avatar f tn Once my depression was under control, I was able to go down to 30 mg daily by taking a 20 mg capsule one day, followed by 2 capsules (40 mg) the next. Because of Prozac's long half-life in the body, it is slowly cleared from your body. This has allowed me to experiment with the dose that work best for me. I have now been taking Prozac for six years and I see no reason to stop taking it. For me it is just another "vitamin" that I need to take to keep my serotonin levels healthy.
Avatar f tn Hi, I have been on Prozac for almost a year, & I can say that for me, it definitely causes insomnia. It is a possibility, but you will have to take it for yourself to see how your body responds. Personally, I did not have any sleeping difficulty on a very low dosage, but after creeping up on milligrams, sleep is a constant struggle. I take Ambien CR every night which helps me sleep anywhere from 5 - 8 hours.
Avatar f tn A better choice for the anxiety your feeling would be Clonazepam which has a longer half life and tends to be far less addicting but Please discuss this with your PCP. Prayers, Blessings, Love, and light. . .
