Final Thoughts on Adipex Side Effects
You may experience some or none of the side effects of Adipex-P listed in this article. Unfortunately, it can be difficult to tell if any particular side effect (such as insomnia) is actually caused by Adipex-P or other factors. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking Adipex-P or if something "just does not seem right." While it may not be a side effect, your healthcare provider will be able to diagnose and treat the problem.
