PAMELOR (NORTRIPTYLINE HYDROCHLORIDE) Rx Drug: For serious adverse events, report them to the FDA by contacting the drug manufacturer or report directly through the
MedWatch voluntary reporting form.
Events listed on this page represent serious and often rare adverse events
reported to pharmaceutical companies, and do not represent typical side
effects for the medication. Find common side effects on the most recent
official drug label
This report, created by AskaPatient.com, is derived from the cases for NORTRIPTYLINE HYDROCHLORIDE reported to the United States Food and Drug Administration (FDA)
FDA Safety Information and Adverse Event Reporting System (FAERS) and
obtained from Open FDA. Data was last
updated with reports received through July 30, 2026.
Adverse Event Reports are submitted to the FAERS database by pharmaceutical companies (mandatory reporting is required by manufacturers, distributors, or importers).
Health care providers such as doctors (voluntary reporting), and patients themselves (voluntary reporting)
report to the FDA directly through the MedWatch program. Those MedWatch
reports are coded and included in the FAERS database. This report mainly
consists of the mandatory reports, because the MedWatch reports are a small
percentage (3 - 5%) of total reports. Link to the MedWatch summary report at
the top of the page for a summary of the directly reported
(voluntary) adverse events for this drug.The number of reports included here might differ
somewhat from the number of reports in the downloadable quarterly FAERS
reports and in the online FAERS dashboard, due to lags in reporting, drug
name differences,
duplicates, and other factors. Open FDA states that it only includes the
most recent version of a case report. It also adds the disclaimer:
"Do not rely on openFDA to make
decisions regarding medical care. While we make every effort to ensure that
data is accurate, you should assume all results are unvalidated."
FDA uses the "MedDRA" classification system to describe reported adverse
reactions. MedDRA is a standardized medical terminology that facilitates
sharing of regulatory information internationally. In some cases, "patient
friendly" terms for the layman designated by MedDRA have been substituted
for medical jargon. Please

Notes
This summary includes ALL reports where the
drug is a "primary OR secondary OR suspected interacting" drug. Typically, reports are filed for the most serious type or "event" and do not represent incidental or minor side effects. The majority
of these reports are mandatory reports submitted by pharmaceutical
companies, who receive complaints from consumers. The reactions, side effects, or "adverse events," represent up to the 20 most
frequently occuring events in the database for a drug related to the event.
This report also features counts of latest known outcomes associated with
reported side effects, but does not provide the specific outcomes for specific
adverse events.
