4.3
Monoamine Oxidase Inhibitors (MAOIs)
Newly added
section
Ziprasidone
is contraindicated in patients taking, or within 14 days of stopping, MAOIs
(including the MAOIs linezolid and intravenous methylene blue) because of an
increased risk of serotonin syndrome [see
Warnings and Precautions (5.4), Drug Interaction (7.3)].
5.4 Serotonin Syndrome
Newly added section:
Ziprasidone can precipitate serotonin syndrome, a
potentially life-threatening condition. The risk is increased with concomitant
use of other serotonergic drugs (including selective serotonin reuptake
inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs),
triptans, tricyclic antidepressants, fentanyl, tramadol, meperidine, methadone,
lithium, tryptophan, buspirone, amphetamines, and St. John’s Wort) and with
drugs that impair metabolism of serotonin, i.e., monoamine oxidase inhibitors
(MAOIs) [see Contraindications (4.3),
Adverse Reactions (6.2), Drug Interactions (7.3)].
Serotonin syndrome signs and symptoms may include
mental status changes (e.g., agitation, hallucinations, delirium, and coma),
autonomic instability (e.g., tachycardia, labile blood pressure, dizziness,
diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor,
rigidity, myoclonus, hyperreflexia, incoordination), seizures, and
gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
The concomitant use of GEODON with MAOIs is
contraindicated. In addition, do not initiate GEODON in a patient being treated
with MAOIs such as linezolid or intravenous methylene blue. If it is necessary
to initiate treatment with an MAOI such as linezolid or intravenous methylene
blue in a patient taking GEODON, discontinue GEODON before initiating treatment
with the MAOI [see Contraindications
(4.3), Drug Interactions (7.3)].
Monitor all patients taking GEODON for the emergence
of serotonin syndrome. Discontinue treatment with GEODON and any concomitant
serotonergic agents immediately if the above symptoms occur, and initiate
supportive symptomatic treatment. If concomitant use of GEODON with other
serotonergic drugs is clinically warranted, inform patients of the increased
risk of serotonin syndrome and monitor for symptoms.

PATIENT COUNSELING
INFORMATION
Newly added information:
Serotonin
Syndrome
Caution
patients about the risk of serotonin syndrome, particularly with the
concomitant use of GEODON with other serotonergic drugs including SSRIs, SNRIs,
triptans, tricyclic antidepressants, opioids, lithium, tryptophan, buspirone,
amphetamines, St. John’s Wort, and with drugs that impair the metabolism of
serotonin (in particular, MAOIs, which include those intended to treat
psychiatric disorders and also others, such as linezolid). Instruct patients to
contact their health care provider, or report to the emergency room, should
they experience signs or symptoms of serotonin syndrome [see Contraindication (4.3), Warnings and Precautions (5.4), Drug
Interactions (7.3)].
PATIENT
INFORMATION
Additions and/or revisions underlined:
Do not take GEODON if you:
…
are taking a monoamine
oxidase inhibitor (MAOI). Ask your healthcare provider or pharmacist if you are
not sure if you take an MAOI, including linezolid or intravenous methylene
blue.
have stopped taking an MAOI
in the last 14 days.
- are allergic to ziprasidone
or any of the ingredients in GEODON.
…
Other
Important Safety Information
A potentially life-threatening problem called
serotonin syndrome can happen when you take GEODON with certain other
medicines.
See
“Who should NOT take GEODON?”
- Call your healthcare provider if you have any of the
following signs and symptoms of serotonin syndrome: agitation, hallucinations,
coma, or other changes in mental status; racing heartbeat, high or low blood
pressure; coordination problems or muscle twitching; nausea, vomiting, or
diarrhea; sweating or fever; muscle rigidity.
