Do you gain weight on paroxetine?

Weight gain is a potential side effect of paroxetine, although not everyone who takes the medication will experience this side effect. In some cases, paroxetine can cause an increase in appetite or changes in metabolism, which can lead to weight gain over time.

Studies have shown that weight gain is more common in people taking paroxetine than in those taking other antidepressant medications. However, the amount of weight gain can vary widely, and some people may not experience any significant changes in weight while taking the medication.

If you are concerned about weight gain while taking paroxetine or any other medication, it’s important to talk to your healthcare provider. They can provide information on potential treatment options or adjustments to your medication regimen, as well as lifestyle changes that may help to manage weight.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
