What Is Paxil
When Paxil (paroxetine) first was approved, it was hailed as a much-needed and welcomed addition to the antidepressant/antianxiety arsenal. In addition to being a serotonin reuptake inhibitor, it also had mild to moderate noradrenergic effects by inhibiting the reuptake of norepinephrine (NRI or NARI) and could be activating, which often helped depressed patients with lethargy. Additionally, Paxil is efficacious in the treatment of generalized anxiety, panic, posttraumatic stress, social phobia, premenstrual dysphoric disorder, and obsessive-compulsive spectrum disorders. Unfortunately, the presence of Paxil side effects is one of the most frequently reported reasons patients discontinue antidepressant medications, and antidepressant medication discontinuation is associated with poorer treatment outcomes.
After a few years in Phase IV post-marketing clinical reporting, paroxetine exhibited a higher than an average number of adverse events reported to both the Food and Drug Administration (FDA) and the manufacturer, GlaxoSmithKline. 
Paroxetine is an effective antidepressant that also has proven effective in treating generalized anxiety, panic, posttraumatic stress, social phobia, premenstrual dysphoric disorder, and obsessive-compulsive spectrum disorders. It also is being used to treat peri-menopausal or menopausal hot flashes. Currently, it has received FDA indications for major depressive disorder, social phobia, generalized anxiety disorder, and hot flashes. However, the Paxil side effects range from congenital birth defects and heart abnormalities to breast and other possible cancers. It also may, along with other SSRIs and SNRIs, increase suicidality, aggression, and akathisia in pediatric patients with incidence outcomes that initially may have been significantly underestimated in clinical trials.
Paxil For Anxiety
Paroxetine, also known by the trade names Aropax, Paxil, Pexeva, Seroxat, Sereupin, and Brisdelle, was first marketed in the U.S. in 1992. Effective for major depression and various anxiety disorders, it quickly gained a sizable share of the antidepressant prescription market. By the late 1990s, paroxetine frequently was being associated with serious drug interactions and medication side effects.
Most significantly, in a major Canadian epidemiological study examining the relationship between antidepressants and diseases, paroxetine was associated with a 620 percent increase in the rate of breast cancer in women who had taken it over a four-year period. Though re-analyses of this investigation discounted the magnitude of these findings, other studies have associated paroxetine with numerous side effects and adverse events not reported in clinical trials. Among these effects on male fertility are birth defects, gestational hypertension, prolonged QT interval in infants, hyperprolactinemia, cognitive impairment in the elderly, autism, sexual side effects, weight gain, suicidality, aggression, and akathisia in children and adolescents. 
Side Effects Of Paxil
Most studies of Paxil discontinuation have focused on the acute phase of treatment. It is probable that the issues involved in discontinuation due to Paxil side effects are different in the acute, continuation, and maintenance phases of treatment. Patients may be willing to tolerate some Paxil side effects, such as sexual dysfunction, early in the course of treatment, but likely they are less willing to tolerate the side effects that reduce their quality of life during ongoing treatment. Therefore, it is important for clinicians to continually be aware of the emergence of Paxil side effects during the continuation and maintenance phases of treatment.

Paroxetine may cause other side effects. Call your doctor if you have any unusual problems while taking this medication. People should speak to a doctor about any changes in their thoughts, feelings, and mood after starting to take antidepressants. They can change the dose, and medication, and help people manage their Paxil side effects symptoms.
How Long Do Paxil Side Effects Last?
Most common Paxil side effects such as nausea, headache, and dizziness, tend to go away within two to four weeks as the body adjusts to the medicine. Some adverse effects, such as sexual problems, may persist. You should take Paxil exactly how it is prescribed. If you have questions or concerns, talk with your doctor.
If a person takes too many antidepressants, they can overdose. Some of the symptoms of an antidepressant drug overdose may include nausea, vomiting, and blurred vision. Symptoms of Paxil drug overdose may include the following:
- Fever, sweating, confusion, fast or irregular heartbeat, and severe muscle stiffness or twitching
- Nausea, vomiting, diarrhea
- Aggressive behavior
- Dark red or brown urine
- Frenzied, abnormally excited mood
Before discontinuing Paxil, talk with your doctor. Some people have reported withdrawal-like symptoms when decreasing or stopping SSRI therapy. It is believed that these symptoms are the result of the brain trying to stabilize serotonin levels after an abrupt change.
Paxil Withdrawal Symptoms
The Paxil withdrawal symptoms that may occur during discontinuation of any SSRI therapy include:
- Muscle Aches
- Electric shock-like sensations in the neck and head
While all of these symptoms are not believed to be dangerous, they can be quite upsetting. When discontinuing an SSRI, your doctor may give you a gradual reduction schedule to avoid these withdrawal-like symptoms.
