What is Paroxetine for?

Paroxetine belongs to a class of medications called selective serotonin reuptake inhibitor (SSRI) like Sertraline. SSRIs are antidepressants which work by allowing a type of chemicals, serotonin, to stay longer in the brain in order to boost mood. It is usually used to treat anxiety, depression, panic disorder, obsessive compulsive disorder and menopausal symptoms.

How to use it?

Paroxetine can be taken by mouth in conventional tablets. It often takes a few weeks to see noticeable improvement in your symptoms. Do not stop Paroxetine abruptly since a withdrawal syndrome can occur. When converting between immediate and controlled-release products, 10 mg of immediate release is equivalent to 12.5 mg of controlled-release. Both forms are dosed once daily.

The usual initial dose of Paroxetine is 5-20 mg daily (or 12.5 mg of the controlled-release). Your doctor may increase the dose based on your response, usually to a maximum of 60 mg per day (or 75 mg of controlled release).

What are the side effects of Paroxetine? 

Common side effects of Paroxetine include excessive sweating, nausea and vomiting, headache, insomnia, ejaculation disorders. For people who are concerned about or experience nausea, switching to Paroxetine controlled-release can help reduce this side effect.
