Does this drug have an activating effect and does it get fat?

You did not write what exactly the drug is about. If you have Prefaxine tagged with the question, please read on. Otherwise, please write a valid trade name for the drug. Prefaxine contains venlafaxine, which is a drug from the group of serotonin and norepinephrine reuptake inhibitors (SNRIs). It is used in the treatment of depression and anxiety disorders. Due to its mode of action, it has an "activating" potential, i.e. it can be particularly beneficial if the disease proceeds with low drive or drowsiness. Uncommonly (in between 1 and 10 people in 1,000), this medicine may affect your weight and may be either weight gain or weight loss. Statistically, therefore, it is more likely that the drug will not contribute at all to how much the patient weighs. However, if such a side effect occurs, it is impossible to determine what severity it will have and whether it will be weight gain or weight loss. Sometimes, in the case of mental illnesses with appetite disorders, the recovery process itself can cause changes in diet and weight fluctuations. Ultimately, however, it is conscious decisions about food and physical activity that will have the greatest impact.
