Is Depression a Focalin XR Side Effect?
Before medicines are approved, they must go through several clinical studies in which thousands of people are given a particular medicine and are then compared to a group of people not given the medicine. In these studies, side effects are always documented. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine. Side effects are then usually separated into those that occur in more than 1 percent of people and those that occur in less than 1 percent of people.
For people taking methylphenidate (which is very similar to Focalin XR), depression was a reported side effect (although the specific frequency was not reported). For Focalin XR specifically, depression was not reported as a common side effect in short-term studies. Based on this data, it is difficult to say how common it is for people taking Focalin XR to experience depression.
