Does Venlafaxine cause weight gain? If so, is it due to the molecule itself or because people feel better and therefore eat more?

Venlafaxine may cause weight gain in about 1 to 2% of cases according to official product information. This means that out of 100 people taking the medication, one or two may gain weight due to the molecule itself. It is relatively low compared to other side effects. If you notice your appetite increasing while taking Venlafaxine, it is recommended to discuss this with your doctor who may suggest trying a different medication. This process often involves trial and error.
