3. Cold Turkey vs. Tapering

Did you quit cold turkey or did you conduct a gradual taper? Antipsychotics like Zyprexa are very serious drugs and the withdrawal effects can be debilitating. It is always recommended to conduct a very gradual taper to allow your body to slowly adjust to functioning without the drug over a period of time. In general the tapering period should be influenced by your current dose as well as how long you took the drug.

If you were on this particular drug for an extended period of time, it is recommended to taper at a rate of 10% per month. By slowly reducing your dose, you will give your neurotransmitters some time to accommodate and adjust to changes in the amount of the drug you ingest. If you are very sensitive to even minor reductions in dose, you can request a liquid compound that will allow you to reduce your dose by fractions of milligrams.

Zyprexa Withdrawal Symptoms: List of Possibilities

Below is a list of symtpoms that you may experience when coming off of Zyprexa. Keep in mind that not everyone will experience every single symptom listed below. You may experience a few of the symptoms or many and the severity of withdrawal will be influenced by individual factors.

Anxiety: Many people report very extreme anxiety when they quit Zyprexa. This is a drug that many people find calming and when taken away, a person can feel extremely anxious. Do your best to practice relaxation exercises and recognize that the anxiety is part of withdrawal.
Appetite changes: While on Zyprexa, many people experience significant increases in appetite. A person may feel as if they are never full and/or are transforming into Hulk as a result of the food that they eat. When coming off of Zyprexa, most people experience decreased appetite.
Bipolar symptoms: Some people may experience a reemergence of Bipolar symptoms (e.g. mania) when they quit taking this drug. If you have Bipolar disorder and are on this medication, proceed slowly and with caution when withdrawing.
Concentration problems: If you find it very difficult to concentrate on tasks such as reading, writing, and/or work, you are not alone. Many people have major difficulties with focusing when they are going through withdrawal. This symptom tends to improve over time as your brain adapts to functioning without the drug.
Confusion: When you experience a bunch of uncomfortable physical symptoms accompanied by foggy thinking, concentration problems, and emotional disturbances, this can result in a state of confusion. If you feel confused often, just know that this will improve over time.
Crying spells: The depression that people experience when quitting an antipsychotic like Zyprexa can be very tough to deal with. This may result in a person crying excessively because they feel so down in the dumps.
Depersonalization: Do you feel unlike your old “normal” self? This is because your neurotransmitters are out of balance and have changed since you took the medication. It will likely take your brain some time to reset its homeostatic functioning.
Depression: Many people report extreme depression when they stop taking this drug. The depression is thought to be a result of lowered levels of dopamine and serotonin. You should eventually experience some lift in mood after some time off of the medication.
Diarrhea: Some people experience diarrhea when they discontinue this medication. This isn’t an extremely common symptom, but one that has been reported. If this is the case, you may want to consider some over the counter Imodium.
Dizziness: Among the most common withdrawal symptoms from any psychiatric medication is that of dizziness. It is common for people to feel very dizzy, especially if the tapering was done too quickly. Dizziness will eventually lessen over time as the brain functioning readjusts.
Fatigue: Most people report excessive tiredness and general fatigue when they come off of Zyprexa. You may have a difficult time performing everyday tasks because your energy level is so low. Just know that your energy level will eventually return as time passes.
Hallucinations: There is evidence pointing to the fact that some people experience psychotic symptoms as a result of withdrawal. This is thought to be a result of changes in dopamine receptor functioning and dopamine levels.
Headaches: Some people experience splitting severe headaches when they come off of this medication. Having headaches accompanied by dizziness can be a very difficult one-two punch. Just know that these should subside after your body restores proper functioning.
Insomnia: This drug tends to calm people down and in many cases makes them sleepy. When coming off of it, the opposite can be true. Some people report such intense anxiety and an inability to fall asleep. Insomnia may persist for quite some time after your last dose. It should improve as you make some lifestyle changes and your neurotransmitter levels change.
Irritability: Do you notice yourself becoming increasingly irritable? If you feel more irritable than normal and little things set you off, it may be a result of withdrawal. Neurotransmitter levels are in fluctuation, which is thought to lead to people feeling irritable.
Memory problems: It is very common to experience poor memory functioning upon drug discontinuation. It isn’t well known as to why these drugs can lead to memory problems. With that said, most people do experience improvements in memory with time off of the drug.
Mood swings: Some people experience pretty severe mood swings upon discontinuation. One minute you may feel as though the withdrawal is over, the next you may feel swamped in a state of deep depression. For this I’m not referring to “bipolar” mood swings, rather just unexpected changes in mood.
Muscle cramps: Those who have taken this medication over the long term may experience muscle cramps and/or weakness during the withdrawal process.
Nausea: Many people report intense nausea during the time in which they discontinue their medication. The nausea can be severe to the point that a person also vomits. In general, the nausea after the last dose shouldn’t last more than a couple weeks.
Panic attacks: Some individuals report experiencing heightened anxiety to the point of panic attacks. In other words, a person experiences such high arousal that everyday activities lead to intense feelings of panic.
Psychosis: It has been documented that withdrawal from antipsychotics can cause psychosis. It is not very common to experience this upon withdrawal, but it does happen. Obviously this may signify the reemergence of schizophrenia, but in those without schizophrenia, it can be part of withdrawal.
Restlessness: If you feel especially restless for no apparent reason, it is likely due to the withdrawal that you are experiencing. The changes in neurotransmitters, elevated level of arousal, and anxious thinking can make a person restless.
Suicidal thinking: It is extremely common to feel suicidal during your withdrawal. You may experience suicidal thoughts that seem as if they will never subside. Over time, these should gradually subside. If you feel suicidal and cannot cope with these thoughts, please seek professional help.
Sweating: Many people sweat intensely when they withdraw from psychiatric drugs – this antipsychotic is no exception. If you notice that you are sweating profusely throughout the day and wake up sweating in the middle of the night, just know it’s part of the process.
Vomiting: Feel flu-like to the point that you are nauseous and keep vomiting? Some people have reported intense vomiting spells during the first week or two when they initially quit this medication. To reduce this symptom, be sure to wean off of Zyprexa as gradually as possible.
Weight loss: Taking this drug is known to increase appetite and slow metabolism, which leads to many people gaining weight. Zyprexa is one of the worst drugs for trying to keep weight off – most people eat way too much food on this drug in particular. When you stop taking it and stay off of it for awhile, you should also lose the weight that you gained.

Yes, I seen that. My concern is that my doctor said switching from the zyprexa to the serequol I should not have any withdrawals. But doesnt the serequol need to get in my system? Im so tired of this. I was on the zyprexa for 7 years at a very low dose.

Many years ago I developed the plan that all psych treatment providers should be required to use psych drugs, just to develop some basic idea of what they ask patients to do! Sometimes the people that are supposed to help us don't know what they're doing. And in conclusion, I had a friend that went through hell tapering off seroquel. Just a heads up...

It's going to take a little while for the Seroquel to build up to a proper level in your blood plasma level. They start you at a lower dose and raise it over a period of weeks. They can't just start you on these drugs at large dosages, it takes your brain time to adjust to these meds and the changes being made when your stopping one and starting another.

And your Pdoc is a little misguided, just because your changing meds doesn't mean one will cancel out the withdrawals of the other. That often works with narcotics, but psych meds are quite different, so the zyprexa needs to tapered down slowly while the Seroquel is being tritated up. It's not an easy process and it's going to take a while to get your meds back to a stable place, so just be ready to have a few weeks of "not feeling great", but things will settle down.

Thanks thats what I thought. I havent taken my zyprexa since thursday and I know thats why I am feeling like this. Its almost impossiblevto get a hold of my doctor. This stinks.
