What is paroxetine HCl used for?
Paroxetine HCl is an SSRI antidepressant approved to treat major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder, generalized anxiety disorder, and posttraumatic stress disorder (PTSD). The extended-release Paxil CR version is also approved for premenstrual dysphoric disorder (PMDD). Your provider will determine which use applies to you.
What is the difference between paroxetine and Paxil?
There is no difference in the active ingredient. Paxil is the brand name and paroxetine HCl is the generic version. Both contain paroxetine and work the same way, but the generic usually costs much less. The FDA holds generics to the same standards for strength, quality, and absorption as the brand.
What are the most common side effects of paroxetine?
Common side effects can include nausea, drowsiness, dizziness, dry mouth, trouble sleeping, sweating, and sexual side effects. Many mild effects ease over the first few weeks. Contact your provider about anything severe or lasting, and seek help right away for signs of a serious reaction such as serotonin syndrome.
Why is it dangerous to stop paroxetine suddenly?
Paroxetine has a short half-life, so stopping it abruptly can trigger a discontinuation (withdrawal) syndrome with symptoms like dizziness, tingling or electric-shock sensations, irritability, and flu-like feelings. Paroxetine has a notably higher risk of this than some other SSRIs. To avoid it, the dose should be lowered gradually under your provider's supervision rather than stopped on your own.
How long does it take for paroxetine to start working?
Some people notice improvements in sleep, energy, or appetite within the first week or two, but the full effect on mood and anxiety often takes about four to six weeks. It is important to keep taking it as prescribed even if you do not feel a difference right away, and to talk with your provider before making any changes.

What is paroxetine HCl and how does it work?

Paroxetine hydrochloride is a selective serotonin reuptake inhibitor (SSRI). It works by increasing the amount of serotonin, a natural chemical messenger, available in the brain, which helps regulate mood and anxiety. It is the generic equivalent of the brand-name drug Paxil, and the same paroxetine hydrochloride is also sold as the extended-release brand Paxil CR.

Paroxetine is FDA-approved to treat several conditions, including major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder (social phobia), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). The extended-release form, Paxil CR, is additionally approved for premenstrual dysphoric disorder (PMDD). Paroxetine is also made as a different salt, paroxetine mesylate, which is sold under the separate brand names Pexeva (for conditions such as depression, OCD, panic disorder, and GAD) and low-dose Brisdelle (7.5 mg, for moderate-to-severe hot flashes of menopause). Because these mesylate products use a different salt form, they are considered separate brands rather than generic substitutes for Paxil. Your provider will decide whether paroxetine is right for your specific condition.

Rx.com compares live prices across more than 60,000 U.S. pharmacies so you can see the real, up-to-date cash price near you rather than guessing. Prices change often, so we do not list a fixed dollar figure here. Enter your ZIP above to see today's price on paroxetine HCl and bring the coupon to the pharmacy counter.

Paroxetine vs. Paxil and other SSRI alternatives

Paroxetine HCl and Paxil contain the same active ingredient and work the same way in the body; the main difference is that generic paroxetine typically costs far less than the brand. The FDA requires generics to meet the same standards for strength, quality, and how the drug is absorbed.

Paroxetine is one of several SSRIs and related antidepressants. If your provider is weighing options, related medicines include sertraline (Zoloft), fluoxetine (Prozac), escitalopram (Lexapro), and citalopram (Celexa), along with the SNRI venlafaxine (Effexor). Each has a somewhat different side-effect and interaction profile, so the right choice is a decision to make with your prescriber. You can compare cash prices on any of these on Rx.com.

Important safety information

Paroxetine carries a boxed warning about an increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults under 25, especially early in treatment or after a dose change; anyone starting the medicine should be watched closely. It should not be combined with MAOIs (this combination is contraindicated) and can raise the risk of serotonin syndrome when taken with other serotonin-affecting drugs such as triptans. Because paroxetine has a short half-life, stopping it suddenly can cause a discontinuation syndrome, so it should be tapered gradually under a provider's guidance rather than stopped on your own.

Other cautions include a higher bleeding risk when combined with NSAIDs or blood thinners, low sodium levels (hyponatremia), especially in older adults, and a risk of angle-closure glaucoma. Paroxetine has also been linked to congenital heart defects with first-trimester use in pregnancy and should be used with caution.
