I've been off my fluoxetine 20 mg for almost 3 weeks and I'm still getting zaps through my body. When should I expect the withdrawal symptoms to cease?

Unusual: For you to have the "zaps" last so long and it is very unusual on Fluoxetine. It may not be from the Fluoxetine. I would advise you ask your doctor to give you 10 mg to take for a few week and see if you feel better. Then if the 10 mg are tablets, you could cut them in half and take 5 mg for a few weeks. This might help getting off of it easier. ...Read more

If your seratonin low cn it cause u 2 hv band headaches & all kinds of horrible symptoms 2 your body. I use to be on Prozac (fluoxetine) 25 mg & now off of it.

If your seratonin low cn it cause u 2 hv band headaches & all kinds of horrible symptoms 2 your body. I use to be on Prozac (fluoxetine) 25 mg & now off of it.

In roundabout way: If you were on Prozac (fluoxetine) and stopped, it's possible to have some uncomfortable discontinuation symptoms [including headaches] even though Prozac (fluoxetine) is less likely than other ssri's to cause these. Another possibility is that Prozac (fluoxetine) was helping you relax, including the muscles around your scalp & forehead, which can tighten into tension headaches. Serotonin doesn't necessarily need to be "low" for this. ...Read more

Prescription drug residue in semen? My boyfriend wants me to perform fellatio on him. He is on fluoxetine and clonazepam. If he comes in my mouth, and I swallow, should I be worried about those drugs being present in his semen, and entering my body?

Prescription drug residue in semen? My boyfriend wants me to perform fellatio on him. He is on fluoxetine and clonazepam. If he comes in my mouth, and I swallow, should I be worried about those drugs being present in his semen, and entering my body?

I would not think so: These drugs are metabolized either in the kidneys or liver and the remnants would be eliminated either in his urine or bowel movements. There is no way that you would find the whole drug present in the semen. ...Read more

What is your opinion on prozac (fluoxetine)?

Prozac (fluoxetine): I agree with drs. Ali and satinover that Prozac (fluoxetine) can be very useful when prescribed and re-assessed carefully. However, I believe it (and other antidepressants) can be over-prescribed too. I have seen non-psychiatrists (as well as psychiatrists) jump to prescription pads when a patient weeps or tells of grief following a death. Not every tear signifies depression requiring prozac (fluoxetine). ...Read more
