The time it takes for paroxetine side effects to go away varies from person to person and is influenced by things including metabolism, the nature of the side effect, and how long the drug has been used.
When the body becomes used to the medicine, paroxetine’s early adverse effects usually go away in the first few weeks of therapy. These may include headaches, light nausea, or trouble sleeping.
Certain adverse effects could last longer or the whole duration of the therapy. For instance, while the drug is being used, sexual adverse effects including lower libido or trouble achieving an orgasm may continue.
