Common Side Effects of Psychiatric Medications
There are many common side effects of psychiatric medications, some of which are pretty similar across different classes of drugs. If you have any of the side effects below, please talk to your doctor the next time you see them. There may be things you and your doctor can do to minimize or reduce the side effects, such as changing the dosage or changing the time or how you take the medication. Please don’t make any medication changes, however, before talking to your doctor.
Many psychiatric medications have general side effects that span virtually all classes of drugs. Gabe Howard talks about these common side effects not commonly talked about: taste changes, memory issues, and frequent urination.
Different patients have different treatment responses and side effects to various psychiatric drugs — there is no single recipe or dosage that works for everyone. A patient may do better with one drug than another. Please keep this in mind as you take your psychiatric medication, and talk to your doctor if any concerns arise or you feel the drug isn’t working (or isn’t working as well as it used to).
