FDA Public Health Advisory
FDA Announces Important Changes and Additional Warnings for COX-2 Selective
and Non-Selective Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
04-07-05
Today, the Food and Drug Administration (FDA) is announcing that it has asked
Pfizer, Inc. to voluntarily withdraw Bextra (valdecoxib) from the market.
Pfizer has agreed to suspend sales and marketing of Bextra in the U.S.,
pending further
discussions with the agency. FDA is also asking manufacturers of all marketed
prescription NSAIDs, including Celebrex (celecoxib), a COX-2 selective NSAID,
to revise the labeling (package insert) for their products to include a boxed
warning and a Medication Guide. The boxed warning will highlight the potential
for increased risk of cardiovascular (CV) events with these drugs and the
well-described, serious, and potentially life-threatening gastrointestinal
(GI) bleeding associated
with their use. The Medication Guide will accompany every prescription NSAID
at the time it is dispensed to better inform patients about the CV and GI
risks. Finally, FDA is asking manufacturers of non-prescription (OTC) NSAIDs
to revise
their labeling to include more specific information about the potential GI
and CV risks, and information to assist consumers in the safe use of the
drug. This
announcement does not apply to aspirin as it has clearly been shown to reduce
the risk of serious adverse CV events in certain patient populations.
In reaching these decisions, FDA has carefully considered the available data
on all of the NSAIDs. The Agency has also considered presentations, discussions,
and votes from the joint public meeting of the FDA Arthritis Advisory Committee
and the Drug Safety and Risk Management Advisory Committee held on February
16, 17, and 18, 2005 to discuss the CV safety concerns for these drugs along
with
their overall risk-benefit.
Specifically, FDA is requesting the actions listed below and will work closely
with the manufacturers to ensure their timely implementation.
BEXTRA (valdecoxib tablets)
FDA has concluded that the overall risk versus benefit profile is unfavorable
and has requested that Pfizer, the manufacturer of Bextra, voluntarily
withdraw Bextra from the market. This request is based on:
Pfizer
has agreed to suspend sales and marketing
of Bextra in the U.S.,
pending further
discussions with the agency.
Patients currently taking Bextra should contact their
physicians to consider alternative treatments.
CELEBREX (celecoxib tablets)
FDA has concluded that the benefits of Celebrex outweigh
the potential risks in properly selected and informed
patients. Accordingly, FDA will
allow Celebrex
to remain on the market and has asked Pfizer to
take the actions
listed below.
Patients who are taking CELEBREX should discuss questions or concerns about this new information with their physician.
Non-Selective NSAIDs
A number of non-selective NSAIDs (prescription and non-prescription (over-the-counter
(OTC)) are approved for marketing in the United States. A list of these products
is attached and is also available at http://www.fda.gov/cder/drug/infopage/cox2/default.htm#list.
Long-term controlled clinical trials have not been conducted with most of
these NSAIDs. However, the available data suggest that use of these drugs
may increase
CV risk. It is very difficult to draw conclusions about the relative CV risk
among the COX-2 selective and non-selective NSAIDs with the data available.
All sponsors of non-selective NSAIDs will be asked to conduct and submit
to FDA a comprehensive review and analysis of available controlled clinical
trial
databases pertaining to their NSAID product(s) to which they have access
to further evaluate the potential for increased CV risk.
FDA will work closely with sponsors and other interested stakeholders (e.g.,
NIH) to encourage additional long-term controlled clinical trials of non-selective
NSAIDs to further evaluate the potential for increased CV risk.
In addition, FDA is requesting labeling changes for both prescription and
OTC non-selective NSAIDs. Because the use and labeling for the prescription
products
is different from those available without a prescription, they are addressed
separately.
Prescription Non-Selective NSAIDs
FDA will request that manufacturers of all prescription products containing
non-selective NSAIDs revise their product labeling to include:
Patients who are taking a prescription non-selective NSAID should discuss questions or concerns about this new information with their physician.
OTC
Non-Selective NSAIDs
The available data do not suggest an increased risk of serious CV events
for the short-term, low-dose use of the NSAIDs available over the counter.
FDA
will allow these products to remain on the market, but will request changes
to the label to better inform consumers regarding the safe use of these
products.
FDA will ask manufacturers of all OTC products containing ibuprofen (Motrin,
Advil, Ibu-Tab 200, Medipren, Cap-Profen, Tab-Profen, Profen, Ibuprohm),
naproxen (Aleve), and ketoprofen (Orudis, Actron) to revise their
labeling to include:
Patients who are taking an OTC NSAID should carefully follow the labeled directions,
particularly with regard to dose and duration of use, and should contact
their physician regarding any questions or concerns they may have about this
new information.
Note: Aspirin is a nonselective NSAID. However, aspirin is also a platelet
inhibitor and has been shown in clinical trials to reduce the risk of CV
events. Patients taking aspirin to prevent CV events should NOT stop
taking it, unless
specifically advised to do so by their physician.
FDA expects that these actions will further encourage the safe and effective use of these products. FDA will continue to notify health care providers and patients in a timely fashion as new information becomes available.
FDA urges health care providers and patients to report adverse event
information the MedWatch program by phone (1-800-FDA-1088), by
fax (1-800-FDA-0178),
or by the Internet at http://www.fda.gov/medwatch/index.html.
