| Generic Name Brand Name (Company) | Warning |
|---|---|
| Anagrelide hydrochloride Agrylin (Shire US) |
WARNINGS …added paragraphs: Anagrelide increases the QTc interval of the electrocardiogram and increases the heart rate in healthy volunteers. Anagrelide should not be used in patients with known risk factors for QT interval prolongation, such as congenital long QT syndrome, a known history of acquired QTc prolongation, medicinal products that can prolong QTc interval, and hypokalemia. In patients with heart failure, bradyarrhythmias, or electrolyte abnormalities, consider periodic monitoring with electrocardiograms. In patients with cardiac disease, use Agrylin only when the benefits outweigh the risks. PRECAUTIONS Hypotension: In 9 subjects receiving a single 5 mg dose of anagrelide, standing blood pressure fell an average of 22/15 mm Hg, usually accompanied by dizziness. Only minimal changes in blood pressure were observed following a dose of 2 mg. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm175918.htm |
| Asparaginase Erwinia chrysanthemi Erwinaze (EUSA Pharma) |
WARNINGS AND PRECAUTIONS Hypersensitivity Reactions Grade 3 and 4 hypersensitivity reactions after the use of Erwinaze have occurred in 5% of patients in clinical trials. Anaphylaxis after the use of Erwinaze has occurred in 0.8% of patients in clinical trials. Glucose Intolerance Glucose intolerance has been reported with Erwinaze therapy in 4% of patients in clinical trials. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm392222.htm |
| Azathioprine Imuran (Prometheus Laboratories) |
WARNINGS Serious Infections - Progressive Multifocal Leukoencephalopathy. Cases of JC virus-associated infection resulting in progressive multifocal leukoencephalopathy (PML), sometimes fatal, have been reported in patients treated with immunosuppressants, including Imuran. Risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function. Consider the diagnosis of PML in any patient presenting with new-onset neurological manifestations and consider consultation with a neurologist as clinically indicated. Consider reducing the amount of immunosuppression in patients who develop PML. In transplant patients, consider the risk that the reduced immunosuppression represents to the graft. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm258794.htm |
| Boceprevir Victrelis (Merck) |
WARNINGS AND PRECAUTIONS Pancytopenia (Use with Ribavirin and Peginterferon Alfa) Serious cases of pancytopenia have been reported postmarketing in patients receiving Victrelis in combination with peginterferon alfa and ribavirin. Complete blood counts (with white blood cell differential counts) should be obtained at pretreatment, and at treatment weeks 2, 4, 8, and 12, and should be monitored closely at other time points, as clinically appropriate. Refer to the Package Inserts for ribavirin and peginterferon alfa for guidelines for discontinuation of therapy based on laboratory parameters. ADVERSE REACTIONS Postmarketing Experience Blood and Lymphatic System Disorders: agranulocytosis, pancytopenia, thrombocytopenia Infections and Infestations: pneumonia, sepsis PATIENT COUNSELING INFORMATION Pancytopenia Patients should be informed that serious cases of pancytopenia have been reported during postmarketing when Victrelis was administered with peginterferon alfa and ribavirin. Patients should be advised that laboratory evaluations are required prior to starting therapy and periodically thereafter http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm303600.htm |
| Cabazitaxel Jevtana (sanofi aventis) |
WARNINGS AND PRECAUTIONS Gastrointestinal Disorders Gastrointestinal (GI) hemorrhage and perforation, ileus, enterocolitis, neutropenic enterocolitis, including fatal outcome, have been reported in patients treated with Jevtana. Risk may be increased with neutropenia, age, steroid use, concomitant use of NSAIDs, anti-platelet therapy, or anti-coagulants, and patients with a prior history of pelvic radiotherapy, adhesions, ulceration, and GI bleeding. Abdominal pain and tenderness, fever, persistent constipation, diarrhea, with or without neutropenia, may be early manifestations of serious GI toxicity and should be evaluated and treated promptly. Jevtana treatment delay or discontinuation may be necessary. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm392358.htm |
| Calcitonin-salmon Miacalcin (Novartis) |
Information from a meta-analysis of 21 randomized, controlled studies was added to the Warnings and Precaution and Adverse Reactions sections regarding the increased risk of malignancies with calcitonin-salmon therapy. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm190771.htm |
| Carbidopa Lodosyn (Valeant Pharmaceuticals North America) |
WARNINGS The addition of Lodosyn with carbidopa-levodopa reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, Lodosyn does not decrease the adverse reactions due to the central effects of levodopa. Because Lodosyn permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, eg, dyskinesias (involuntary movements), may occur at lower dosages and sooner with levodopa in combination with Lodosyn than with levodopa alone. Falling Asleep During Activities of Daily Living and Somnolence Neuroleptic Malignant Syndrome (NMS) section revised into Hyperpyrexia and Confusion PRECAUTIONS Sections added: Impulse Control/Compulsive Behaviors; Hallucinations/Psychotic Like Behavior; Dyskinesia; Depression; Melanoma Information for Patients DRUG INTERACTIONS Lodosyn and iron salts or multivitamins containing iron salts should be coadministered with caution. Iron salts can form chelates with levodopa and carbidopa and consequently reduce the bioavailability of carbidopa and levodopa. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm388773.htm |
| Eltrombopag Promacta (GlaxoSmithKline) |
BOXED WARNING WARNING: RISK FOR HEPATIC DECOMPENSATION IN PATIENTS WITH CHRONIC HEPATITIS C In patients with chronic hepatitis C, Promacta in combination with interferon and ribavirin may increase the risk of hepatic decompensation. WARNINGS AND PRECAUTIONS Hepatic Decompensation in Patients With Chronic Hepatitis C Revised to include the risk of hepatic decompensation. Hepatotoxicity Promacta can cause liver enzyme elevations. Measure serum ALT, AST, and bilirubin prior to initiation of Promacta, every 2 weeks during the dose adjustment phase, and monthly following establishment of a stable dose. Promacta inhibits UGT1A1 and OATP1B1, which may lead to indirect hyperbilirubinemia. Bone Marrow Reticulin Formulation …section removed. Laboratory Monitoring…section removed. ADVERSE REACTIONS Hepatic Decompensation in Patients With Chronic Hepatitis C PATIENT COUNSELING INFORMATION Confusion Swelling of the stomach area (abdomen) http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm207394.htm |

| Everolimus Afinitor (Novartis) |
WARNINGS AND PRECAUTIONS Impaired Wound Healing Everolimus delays wound healing and increases the occurrence of wound-related complications like wound dehiscence, wound infection, incisional hernia, lymphocele, and seroma. These wound-related complications may require surgical intervention. Exercise caution with the use of Afinitor in the peri-surgical period. Embryo-fetal Toxicity Based on the mechanism of action, Afinitor can cause fetal harm. Everolimus caused embryo-fetal toxicities in animals at maternal exposures that were lower than human exposures. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Advise female patients of reproductive potential to avoid becoming pregnant and to use highly effective contraception while using Afinitor and for up to 8 weeks after ending treatment.

| Fluconazole Diflucan (Pfizer) |
CONTRAINDICATIONS Coadministration of other drugs known to prolong the QT interval and which are metabolized via the enzyme CYP3A4 such as erythromycin are contraindicated in patients receiving fluconazole. WARNINGS Patients with deep seated fungal infections who develop rashes during treatment with Diflucan should be monitored closely and the drug discontinued if lesions progress. Fluconazole should be discontinued in patients treated for superficial fungal infection who develop a rash that may be attributed to fluconazole. PRECAUTIONS Drug Interactions Cyclosporine: Diflucan significantly increases cyclosporine levels in renal transplant patients with or without renal impairment. Careful monitoring of cyclosporine concentrations and serum creatinine is recommended in patients receiving Diflucan and cyclosporine. This combination may be used by reducing the dosage of cyclosporine depending on cyclosporine concentration. Quinidine: Although not studied in vitro or in vivo, concomitant administration of fluconazole with quinidine may result in inhibition of quinidine metabolism. Use of quinidine has been associated with QT prolongation and rare occurrences of torsades de pointes. Coadministration of fluconazole and quinidine is contraindicated. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm262570.htm |
| Golimumab Simponi Aria (Janssen) |
WARNINGS AND PRECAUTIONS Serious Infections - Tuberculosis Cases of active tuberculosis have occurred in patients treated with the subcutaneous formulation of golimumab during and after treatment for latent tuberculosis. Monitor patients for the development of signs and symptoms of tuberculosis including patients who tested negative for latent tuberculosis infection prior to initiating therapy, patients who are on treatment for latent tuberculosis, or patients who were previously treated for tuberculosis infection. Vaccinations/Therapeutic Infectious Agents Live Vaccines Patients treated with Simponi Aria may receive vaccinations, except for live vaccines. In patients receiving anti-TNF therapy, limited data are available on the response to live vaccination, or on the secondary transmission of infection by live vaccines. Use of live vaccines could result in clinical infections, including disseminated infections. Therapeutic Infectious Agents Other uses of therapeutic infectious agents such as live attenuated bacteria (eg, BCG bladder instillation for the treatment of cancer) could result in clinical infections, including disseminated infections. It is recommended that therapeutic infectious agents not be given concurrently with Simponi Aria. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm388774.htm |

| Naproxen/esomeprazole magnesium Vimovo (Horizon Pharma) |
WARNINGS AND PRECAUTIONS Renal Effects Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion; those taking diuretics, ACE inhibitors, or angiotensin II receptor antagonists; and the elderly. Laboratory Tests Health care providers should temporarily stop esomeprazole treatment at least 14 days before assessing CgA levels and consider repeating the test if initial CgA levels are high. If serial tests are performed (eg, for monitoring), the same commercial laboratory should be used for testing, as reference ranges between tests may vary. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm262248.htm |
| Palonosetron hydrochloride Aloxi (EISAI) |
WARNINGS AND PRECAUTIONS Hypersensitivity reactions, including anaphylaxis, have been reported with or without known hypersensitivity to other 5-HT3 receptor antagonists. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm388768.htm |
| Rifaximin Xifaxan (Salix Pharmaceuticals) |
WARNINGS AND PRECAUTIONS Concomitant use with P-glycoprotein Inhibitors Concomitant administration of drugs that are P-glycoprotein inhibitors with rifaximin can substantially increase the systemic exposure to rifaximin. Caution should be exercised when concomitant use of rifaximin and a P-glycoprotein inhibitor such as cyclosporine is needed. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P-glycoprotein inhibitors may further increase the systemic exposure to rifaximin. DRUG INTERACTIONS Concomitant P-glycoprotein inhibitors An in vitro study suggested that rifaximin is a substrate of P-glycoprotein. Co-administration of cyclosporine, a potent P-glycoprotein inhibitor, with rifaximin resulted in 83-fold and 124-fold increases in rifaximin mean Cmax and AUC in healthy subjects. The clinical significance of this increase in systemic exposure is unknown. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm392729.htm |
| Rivaroxaban Xarelto (Janssen) |
BOXED WARNING Optimal timing between the administration of Xarelto and neuraxial procedures is not known. WARNINGS AND PRECAUTIONS Spinal/Epidural Anesthesia or Puncture To reduce the potential risk of bleeding associated with the concurrent use of rivaroxaban and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of rivaroxaban. Placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of rivaroxaban is low; however, the exact timing to reach a sufficiently low anticoagulant effect in each patient is not known. Should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, monitor frequently to detect any signs or symptoms of neurological impairment, such as midline back pain, sensory and motor deficits (numbness, tingling, or weakness in lower limbs), bowel and/or bladder dysfunction. Instruct patients to immediately report if they experience any of the above signs or symptoms. If signs or symptoms of spinal hematoma are suspected, initiate urgent diagnosis and treatment including consideration for spinal cord decompression even though such treatment may not prevent or reverse neurological sequelae. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm367392.htm |
| Sevoflurane, volative liquid for inhalation Ultane & Ultane NovaPlus (AbbVie) |
WARNINGS Reports of QT prolongation, associated with torsade de pointes (in exceptional cases, fatal), have been received. Caution should be exercised when administering sevoflurane to susceptible patients (eg, patients with congenital long QT syndrome or patients taking drugs that can prolong the QT interval). http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm319035.htm |
| Sildenafil Revatio & Viagra (Pfizer) |
WARNINGS AND PRECAUTIONS Effects on the Eye Based on published literature, the annual incidence of non-arteritic anterior ischemic optic neuropathy (NAION) is 2.5-11.8 cases per 100,000 in males aged ≥ 50. An observational study evaluated whether recent use of PDE5 inhibitors, as a class, was associated with acute onset of NAION. The results suggest an approximate 2-fold increase in the risk of NAION within 5 half-lives of PDE5 inhibitor use. http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm319416.htm http://www.fda.gov/Safety/MedWatch/SafetyInformation/ucm200593.htm |

BOXED WARNING Life-Threatening Adverse Reactions: Hepatotoxicity Hepatic failure resulting in fatalities has occurred in patients receiving valproic acid and its derivatives. These incidents usually have occurred during the first 6 months of treatment. Serious or fatal hepatotoxicity may be preceded by non-specific symptoms such as malaise, weakness, lethargy, facial edema, anorexia, and vomiting. In patients with epilepsy, a loss of seizure control may also occur. Patients should be monitored closely for appearance of these symptoms. Serum liver tests should be performed prior to therapy and at frequent intervals thereafter, especially during the first 6 months. Populations at increased risk include: children under the age of 2 years are at a considerably increased risk of developing fatal hepatotoxicity, especially those on multiple anticonvulsants, those with congenital metabolic disorders, those with severe seizure disorders accompanied by mental retardation, and those with organic brain disease; incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups; and patients with mitochondrial disease (patients with hereditary neurometabolic syndromes caused by DNA mutations of the mitochondrial DNA Polymerase γ [POLG] gene [eg, Alpers Huttenlocher Syndrome]).
