What is Paxil

Paroxetine

The Generic name of this drug

Treatment Summary

Paroxetine, better known as Paxil, is a type of medication known as a selective serotonin reuptake inhibitor (SSRI). It is most commonly used to treat anxiety disorders, depression, post-traumatic stress disorder (PTSD), and menopause symptoms. This drug is more potent than other SSRIs, meaning it is more likely to cause withdrawal effects when stopped. Paroxetine is generally well-tolerated and has similar side effects to other SSRIs. The extended release version of the drug is designed to reduce the chance of nausea.

Effectiveness

How Paxil Affects Patients

Paroxetine is used to treat symptoms of depression, different types of anxiety, posttraumatic stress disorder, obsessive-compulsive disorder, and the hot flashes of menopause. It works by blocking the chemical serotonin in the brain. It usually takes about 6 weeks for the medication to start working. Paroxetine should not be taken with monoamine oxidase (MAO) inhibitors, as it could cause a serious side effect called serotonin syndrome. If you are taking MAO inhibitors, you must wait two weeks before taking paroxetine.

How Paxil works in the body

Paroxetine helps increase the amount of serotonin in the brain. It does this by blocking the serotonin receptor, which prevents serotonin from being taken back into the neurons. This leads to higher levels of serotonin in the brain, which can help relieve symptoms. It is also thought to help with symptoms of menopause, though it is not clear exactly how it works. Paroxetine also binds to other receptors in the brain such as adrenergic, dopamine, histamine, serotonin, and muscarinic cholinergic receptors. These additional receptors may be the reason why it takes some time for Paroxetine to take effect,

Patient Review

Paxil for Panic Disorder

Paxil was a great medication for me for six years. I began to get depressed due to my weight gain, and it took three tries to come off of Paxil. Awful awful time.

Paxil for "Change of Life" Signs

Overall, I've been really pleased with this treatment. It's helped with my OCD and anxiety without any noticeable side effects. The only downside is that it's decreased my sex drive and appetite, but those are small prices to pay for the benefits I've seen so far.

Patient Review

6/24/2022

Paxil for Repeated Episodes of Anxiety

I've dealt with anxiety, depression, and social anxiety for a long time now. I tried many different medications but they all made me feel awful. About four months ago, I started taking Paxil and my life changed. I felt better almost immediately. It's been an amazing difference and has helped me focus on things other than my anxieties. The only downside is that my eyes always feel heavy, even when I'm not tired.

Paxil for Panic Disorder

This medication was effective in treating my anxiety; however, I experienced significant weight gain as a result. Additionally, the withdrawal symptoms were very unpleasant.

Patient Review

1/27/2022

Paxil for Depression

This medication helped me recover from a bad reaction to another drug, and I felt better relatively quickly. However, it makes me drowsy all the time and I've gained a lot of weight since starting it; so much so that I'm now diabetic. I want to go off the medication because I feel like the diabetes is worse than any depression.

Patient Review

5/3/2022

Paxil for Repeated Episodes of Anxiety

I'm 39 and this medication has made me start losing my hair and gain weight, which are both major cons for me. The pros don't outweigh the negatives here. I would recommend that people avoid this if possible.

Patient Review

4/25/2022

Paxil for Depression

I found that Paxil did help with my depression and anxiety; however, I also gained 15 pounds while taking it. Additionally, I experienced some negative cardiovascular effects like stiffness in my muscles and shortness of breath. For these reasons, I stopped taking the medication.

Patient Review

5/13/2022

Paxil for Depression

If I missed a dose of Paxil, I would have withdrawal symptoms within hours. They were awful and made it hard to live a normal life day-to-day.

Patient Review

7/26/2019

Paxil for "Change of Life" Signs

Though this was prescribed because I can't take hormones, it's caused me new problems. I'm now having trouble sleeping and am constipated; while my hot flashes have diminished, they're not gone entirely. Additionally, I've become more emotionally stable--which isn't necessarily a good thing in all situations. All things considered, I think I'll stop taking the medication.

Patient Review

1/1/2022

Paxil for Depression

While this treatment did alleviate some of my depression and anxiety, it was not a cure-all. I also experienced significant weight gain while taking the medication; even after stopping the medication, I have been unable to lose the weight.

Patient Review

12/31/2021

Paxil for Depression

I experienced intense negative side effects from this Paxil prescription, including brain fog, emotional blunting, fatigue, severe cognitive impairment, and sexual dysfunction. These symptoms have been debilitating and long-lasting.

Patient Review

10/4/2020

Paxil for "Change of Life" Signs

I have been on Paxil for 4 days. I have never taken any type of anxiety or depression medication before. I am on 20mg a day. I feel severe, debilitating fatigue and apathy on this. Can't concentrate. Find myself staring into space. Have had odd side effects like twitching in limbs and face. Blurry eyesight. I just want to sleep all day. Difficult even to speak. I don't like this and I'm calling my dr tomorrow about stopping it.

Patient Review

Paxil for Anxiousness associated with Depression

Since I started taking this medication at the end of January 2020, I have been feeling increasingly disconnected from reality. This has been extremely disorienting and disruptive to my life. My psychiatrist is switching me to a different medication, and I am hoping that will help alleviate these effects.

Cognitive Behavioral Therapy for Post-Traumatic Stress Disorder

7 - 14
All Sexes
Houston, TX

One of the most common and widely disseminated trauma treatments is Trauma Focused Cognitive Behavioral Therapy (TF-CBT). TF-CBT is a therapist-led, structured and sequential intervention, with treatment organized around P.R.A.C.T.I.C.E. (Psychoeducation, Parent training, Relaxation, Affective Regulation, Cognitive Coping, Trauma Narrative, In-Vivo Exposure, Cognitive Reprocessing, and Enhancing Safety) components. Stepped Care Cognitive Behavioral Therapy for Children after Trauma (SC-CBT-CT) is an alternative delivery system that incorporates the best available evidence on the treatment of childhood Post-traumatic Stress Disorder (PTSD) within a stepped care model and utilizes task-shifting with caregiver involvement, which engages caregivers in actively helping their children. Stepped care approaches are characterized by a personalized approach to care in which a lower intensity (i.e., fewer number of sessions) intervention is initially provided before the child is reevaluated or ''stepped up'' for additional care should symptoms persist. The goal of this study is to assess a personalized modification of SC-CBT-CT for Latino families (pSC-CBT-CT). The hypothesis is that personalizing SC-CBT-CT will improve outcomes for Latino children.

All Sexes
Pittsburgh, PA

The goal of this prospective, randomized clinical trial is to learn whether pharmacogenomic (PGx)-guided comprehensive medication management delivered by pharmacists in community pharmacies will improve antidepressant treatment outcomes. The primary aim is to determine whether comprehensive medication management with review of PGx testing results improves depression symptoms, compared with usual care. Participants 18 years of age or older who have undergone PGx testing (e.g. through an independent biobanking study (Pitt+Me Discovery) who require initiation or adjustment of antidepressant therapy will be randomly assigned to receive either PGx-guided comprehensive medication management or usual care. Those who receive usual care will receive their PGx results at the end of the study. Researchers will compare the groups to assess whether PGx-guided care provided in partnership with community pharmacists and prescribers results in better depression and medication outcomes.
