how long does fluoxetine take to work ive been takeing them for three weeks and im very up and down at the mom

Answer 1

Generally speaking, the SSRI's will begin to kick in at around 2 weeks and achieve maximum efficacy by 4-6 weeks. You did not indicate what dose you are on, but be aware that the efficacy is often dose-related. Some people with mild symptoms achieve an adequate therapeutic response at low doses, for others they may not achieve full or immediate relief until the dose is raised. Just a word of caution here if you are receiving your meds through your primary doc-it's been my experience that primary docs are often hesitant to raise dosages to therapeutic levels and often discard a medication as not working simply because they have not given it an adequate trial and are prescribing at sub-therapeutic levels. Talk with your doc about your dosage and what the ceiling dose is and if you are feeling some effect, but not enough, ask them to consider raising the dose before assuming the med isn't working adequately.

Answer 2

G'Morning...
Here is something I found on the matter...hope it helps. In MY opinion that...it may take more than 3 weeks for you to get the full effects of this medication.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Obsessive-Compulsive Disorder (OCD) - Medications
Once you are diagnosed with obsessive-compulsive disorder (OCD), your health professional will likely prescribe antidepressants known as selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (for example, Prozac). Antidepressants are thought to help balance neurotransmitters (such as serotonin) in your brain.

In some cases it takes time to adjust the dosage or find the right medication that will work for you. It may take several weeks before you feel the effects of an antidepressant. Your doctor may increase the dosage of your medication, change to another SSRI, or use another medication known as clomipramine if the drugs first prescribed do not help. Clomipramine, a tricyclic antidepressant, has been used for years to treat OCD, but it may have more side effects than SSRIs.

Your doctor may prescribe other medications if you have other conditions along with OCD.

Answer 3

It took about a month for me to really feel the effects, and then about 3-6 months for it to completely regulate itself.
