Thank you for your question and welcome to AnxietyConnection.com.
Paxil and Pexeva contain paroxetine as their active ingredient. Both are in the group of SSRI antidepressants. Pexeva is less expensive
Pexeva is manufactured by Synthon Pharmaceuticals and according to an article on Biospace.com, "PEXEVA is bioequivalent to GlaxoSmithKline's Paxil®(1), which is composed of paroxetine hydrochloride. The chemical difference between the two products is the inactive salt portion of the active ingredient (PEXEVA's mesylate vs. PAXIL's hydrochloride). The inactive salt is separated from the active paroxetine molecule in the gastrointestinal tract, leaving only the active paroxetine molecule to be absorbed into the bloodstream and provide the intended therapeutic effect."
Many antidepressants can cause weight gain but not everyone that takes these medications gain weight, this would depend on the individual. Since everyone reacts differently to medications, it is impossible to say whether you would gain weight from the medication.
