Medication Safety
Information regarding select medication safety issues can be found on the Caremark Web site at www.caremark.com > For Health Professionals > Drug Safety Alerts.
Zelnorm® (tegaserod) U.S. Suspension of Marketing and Sales5
On March 30, 2007, the U.S. Food and Drug Administration (FDA) issued a Public Health Advisory (PHA) to alert the public that Novartis
Pharmaceuticals Corporation has agreed to stop marketing Zelnorm, a medication approved for short-term treatment of women with irritable
bowel syndrome with constipation and for patients younger than 65 years with chronic constipation.
• The Zelnorm suspension of U.S. marketing and sales is occurring as a result of a new safety analysis of 29 clinical studies that found a higher
chance of heart attack, stroke and worsening chest pain that can lead to a heart attack in patients treated with Zelnorm compared to those
treated with placebo.
• Physicians who prescribe Zelnorm should work with their patients and transition them to other therapies as appropriate to their symptoms
and needs.
• There may be patients for whom no other treatment options are available and in whom the benefits of Zelnorm treatment outweigh the
chance of serious side effects. The FDA will work with Novartis to allow access to Zelnorm for those patients through a special program.
This medication safety issue has been reviewed by the Caremark Drug Safety Committee. Caremark has created iScribe®, physician, client
and participant communications regarding this issue.
FDA Issues Permax® (pergolide) PHA6
On March 29, 2007, the FDA issued a PHA notifying the public that the companies that manufacture and distribute both the brand and
generic versions of pergolide have agreed to withdraw the medication from the market due to the potential for heart valve damage. Pergolide
is a dopamine agonist (DA) used with levodopa and carbidopa to manage the signs and symptoms (tremors and slowness of movement) of
Parkinson’s disease (PD).
• Two new studies showed that patients with PD who were treated with pergolide had an increased chance of serious damage to their heart
valves when compared to patients who did not receive the drug. These two studies confirm earlier studies that also describe this problem.
• Patients currently taking pergolide should contact their healthcare professional about alternate treatments and not abruptly stop taking their
medication. Healthcare professionals should assess their patient’s need for DA therapy. If continued treatment with a DA is necessary,
another DA should be substituted for pergolide.
This medication safety issue has been reviewed by the Caremark Drug Safety Committee. Caremark has created iScribe®, physician and
participant communications regarding this issue.

FDA Request Labeling Change for Sleep Disorder Medications7
On March 14, 2007, the FDA notified healthcare professionals of its request for manufacturers of sedative-hypnotics products – a class of
medications used to induce and/or maintain sleep – to strengthen labeling to include stronger language concerning potential risks.
• Risks include severe allergic reactions and complex sleep-related behaviors, which may include sleep-driving, making phone calls, and
preparing and eating food (while asleep). Sleep-driving refers to driving while not fully awake after taking a sedative-hypnotic product, with
no memory of the event.
• Along with the labeling revisions, the FDA requested that each manufacturer send letters to healthcare providers to notify them about the
new warnings, and to develop Patient Medication Guides to inform consumers about risks and advise them of precautions that can be taken.
This medication safety issue has been reviewed by the Caremark Drug Safety Committee; it has been determined that no action is needed to
further notify plan participants, physicians or clients at this time.
FDA Issues PHA to Announce Strengthened Safety Information for Erythropoiesis Stimulating Agents (ESAs)8
On March 9, 2007, the FDA issued a PHA regarding new safety information, including revised product labeling, for the ESAs Aranesp®
(darbepoetin alfa, Amgen Inc.), Epogen® (epoetin alfa, Amgen, Inc.) and Procrit® (epoetin alfa, Ortho Biotech Products, L.P.). These
medications are commonly used in the treatment of anemia.
• Based on results from recent studies, product labeling for the ESAs was revised to include a new boxed warning, updated warnings, and a
change to the dosage and administration sections.
• Information from four new studies in patients with cancer showed a higher chance of serious and life-threatening side effects and/or death
with the use of ESAs; the studies involved an unapproved dosing regimen, a patient population for which ESAs are not approved, or a new
unapproved ESA.
• Another study of patients scheduled for orthopedic surgery showed a higher rate of deep vein thrombosis when treated with Procrit at the
approved dose.
• This new information is consistent with risks found in two studies in patients with chronic renal failure treated with an unapproved regimen
of an ESA that were reported in November 2006.
• The new boxed warning advises physicians to monitor hemoglobin levels and to adjust the ESA dose to maintain the lowest hemoglobin
level needed to avoid blood transfusions.
• Physicians and patients should carefully weigh the risks of ESAs against transfusion risks.
• The FDA is in the process of reevaluating how to safely use this class of medications.
This medication safety issue has been reviewed by the Caremark Drug Safety Committee. Caremark has created iScribe® and physician
communications regarding this issue.
FDA Issues Actimmune® (interferon gamma-1b) PHA9
On March 5, 2007, the FDA issued a PHA regarding the early halt of the INSPIRE clinical study of Actimmune (InterMune, Inc.) for idiopathic
pulmonary fibrosis (IPF). Actimmune is not FDA-approved for treating IPF.
• The study was stopped early because an interim analysis showed that patients with IPF who received Actimmune did not benefit. The analysis
showed that 14.5 percent of patients treated with Actimmune died as compared to 12.7 percent with placebo.
• Patients being treated with Actimmune for IPF should discuss with their physicians whether they should continue to receive Actimmune.
• Actimmune is a biologic response modifier that is FDA-approved to reduce the frequency and severity of infections in patients with chronic
granulomatous disease and to delay progression of severe, malignant osteopetrosis.
