Will I gain weight while taking Paxil?
It’s not uncommon to gain weight while taking antidepressants such as Paxil. Antidepressants can affect different enzymes in your liver which can alter your metabolism. This can cause you to gain weight more easily. Everyone is different, of course, so while someone might gain a lot of weight another person won’t be affected at all. The key to keeping your weight under control is to make smart food choices and exercise regularly.
