Strattera Side Effects: An Introduction

As with any medicine, there are possible side effects with Strattera® (atomoxetine hydrochloride). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it well. When people do develop Strattera side effects, in most cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.

Common Side Effects Seen With Strattera

Strattera has been thoroughly studied in clinical trials, with many people having been evaluated.
