Medication Side Effects

There's no simple answer to when patients ask what the side effects of a particular medication are. The purpose of this page is to educate you, as our patients, on possible side effects to psychiatric medications by listing a few side effects. However, this does not indicate that these are the only explicit side effects to these medications, for every patient and body may respond differently to the same medications.
