PATIENT PACKAGE INSERT

BOXED WARNING

Aptivus co-administered with 200 mg Ritonavir has been associated with reports of both fatal and non-fatal intracranial hemorrhage.

WARNINGS/Intracranial Hemorrhage

Aptivus, co-administered with 200 mg of ritonavir, has been associated with reports of both fatal and non-fatal intracranial hemorrhage (ICH). Many of these patients had other medical conditions or were receiving concomitant medications that may have caused or contributed to these events. No pattern of abnormal coagulation parameters has been observed in patients in general, or preceding the development of ICH. Therefore, routine measurement of coagulation parameters is not currently indicated in the management of patients on Aptivus.

WARNINGS/Platelet Aggregation Inhibition

In in vitro experiments, tipranavir was observed to inhibit human platelet aggregation at levels consistent with exposures observed in patients receiving Aptivus/ritonavir.

Aptivus/ritonavir should be used with caution in patients who may be at risk of increased bleeding from trauma, surgery or other medical conditions, or who are receiving medications known to increase the risk of bleeding such as antiplatelet agents or anticoagulants.

WARNINGS/Drug Interactions

A drug interaction study in healthy subjects has shown that ritonavir significantly increases plasma fluticasone propionate exposures, resulting in significantly decreased serum cortisol concentrations. Concomitant use of Aptivus/ritonavir and fluticasone propionate may produce the same effects.....

Particular caution should be used when prescribing phosphodiesterase (PDE5) inhibitors for erectile dysfunction (e.g., sildefafil, tadalafil, or vardenafil) in patients receiving protease inhibitors, including Aptivus.....

MEDICATION GUIDE

BOXED WARNING/Cardiovascular Risk

NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk.

Prevacid NapraPAC is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.

BOXED WARNING/Gastrointestinal Risk

NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding and perforation of the stomach and intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Patients with a history of gastric and/or duodenal ulcers (especially patients with a history of bleeding or perforation) and geriatric patients are at greater risk for serious gastrointestinal events.

CONTRAINDICATIONS

Prevacid NapraPAC is contraindicated in patients who have experienced aspirin or NSAID-related asthma, urticaria, or allergic-type reactions. Severe, rarely fatal, anaphylactic reactions to NSAIDs have been reported in such patients.

Prevacid NapraPAC is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.

MEDICATION GUIDE

CONTRAINDICATIONS

Concomitant administration of Prevpac with cisapride, pimozide, astemizole, terfenadine, ergotamine or dihydroergotamine is contraindicated.

WARNINGS/Clarithromycin

There have been post-marketing reports of colchicine toxicity with concomitant use of clarithromycin and colchicine, especially in the elderly, some of which occurred in patients with renal insufficiency. Deaths have been reported in some such patients.

PRECAUTIONS/Drug Interactions

Clarithromycin

Colchicine is a substrate for both CYP3A and the efflux transporter, P-glycoprotein (Pgp). Clarithromycin and other macrolides are known to inhibit CYP3A and Pgp. When clarithromycin and colchicine are administered together, inhibition of Pgp and/or CYP3A by clarithromycin may lead to increased exposure to colchicine. Patients should be monitored for clinical symptoms of colchicine toxicity.

CYP3A Drug Interactions:  Ergotamine/dihydroergotamine

Post-marketing reports indicate that coadministration of clarithromycin with ergotamine or dihydroergotamine has been associated in some patients with acute ergot toxicity characterized by vasospasm and ischemia of the extremities and other tissues including the central nervous system. Concomitant administration of clarithromycin with ergotamine or dihydroergotamine is contraindicated.

Coreg (carvedilol) Tablets

(click product name to read prescribing information)

WARNINGS
  • Diabetes and Hypoglycemia

PRECAUTIONS

  • Effects on Glycemic Control in Type 2 Diabetic Patients
    • .....In a study designed to examine the effects of carvedilol on glycemic control in a population with mild-to-moderate hypertension and well-controlled type 2 diabetes mellitus, carvedilol had no adverse effect on glycemic control, based on HbA1c measurements.

In general, β-blockers may mask some of the manifestations of hypoglycemia, particularly tachycardia. Nonselective β-blockers may potentiate insulin-induced hypoglycemia and delay recovery of serum glucose levels. Patients subject to spontaneous hypoglycemia, or diabetic patients receiving insulin or oral hypoglycemic agents, should be cautioned about these possibilities. In congestive heart failure patients, there is a risk of worsening hyperglycemia.

Epzicom (abacavir sulfate and lamivudine) Tablets

(click product name to read prescribing information)

WARNINGS
  • Use With Interferon- and Ribavirin-Based Regimens

PRECAUTIONS

  • Immune Reconstitution Syndrome

MEDICATION GUIDE

In vitro studies have shown ribavirin can reduce the phosphorylation of pyrimidine nucleoside analogues such as lamivudine, a component of Epzicom. Although no evidence of a pharmacokinetic or pharmacodynamic interaction (e.g., loss of HIV/HCV virologic suppression) was seen when ribavirin was coadministered with lamivudine in HIV/HCV co-infected patients, hepatic decompensation (some fatal) has occurred in HIV/HCV co-infected patients receiving combination antiretroviral therapy for HIV and interferon alfa with or without ribavirin. Patients receiving interferon alfa with or without ribavirin and Epzicom should be closely monitored for treatment-associated toxicities, especially hepatic decompensation. Discontinuation of Epzicom should be considered as medically appropriate. Dose reduction or discontinuation of interferon alfa, ribavirin, or both should also be considered if worsening clinical toxicities are observed, including hepatic decompensation (e.g., Childs Pugh >6).....

Forane (isoflurane, USP) Liquid for Inhalation

(click product name to read prescribing information)

WARNINGS
  • Perioperative Hyperkalemia

  • Malignant Hyperthermia

PRECAUTIONS

  • General
    • As with other halogenated anesthetic agents, Forane (isoflurane, USP) may cause sensitivity hepatitis in patients who have been sensitized by previous exposure to halogenated anesthetics.

ADVERSE REACTIONS

  • There have been rare post-marketing reports of hepatic failure and hepatic necrosis associated with the use of potent volatile anesthetic agents, including Forane (isoflurane, USP). Due to the spontaneous nature of these reports, the actual incidence and relationship of Forane (isoflurane, USP) to these events cannot be established with certainty.

WARNINGS/Perioperative Hyperkalemia

Use of inhaled anesthetic agents has been associated with rare increases in serum potassium levels that have resulted in cardiac arrhythmias and death in pediatric patients during the postoperative period. Patients with latent as well as overt neuromuscular disease, particularly Duchenne muscular dystrophy, appear to be most vulnerable. Concomitant use of succinylcholine has been associated with most, but not all, of these cases. These patients also experienced significant elevations in serum creatinine kinase levels and, in some cases, changes in urine consistent with myoglobinuria. Despite the similarity in presentation to malignant hyperthermia, none of these patients exhibited signs or symptoms of muscle rigidity or hypermetabolic state. Early and aggressive intervention to treat the hyperkalemia and resistant arrhythmias is recommended, as is subsequent evaluation for latent neuromuscular disease.

WARNINGS/Malignant Hyperthermia

In susceptible individuals, isoflurane anesthesia may trigger a skeletal muscle hypermetabolic state leading to high oxygen demand and the clinical syndrome known as malignant hyperthermia. The syndrome includes nonspecific features such as muscle rigidity, tachycardia, tachypnea, cyanosis, arrhythmias, and unstable blood pressure. (It should also be noted that many of these nonspecific signs may appear with light anesthesia, acute hypoxia, etc.)

Treatment includes discontinuance of triggering agents (e.g., isoflurane), administration of intravenous dantrolene sodium, and application of supportive therapy. Such therapy includes vigorous efforts to restore body temperature to normal, respiratory and circulatory support as indicated, and management of electrolyte-fluid-acid-base derangements. (Consult prescribing information for dantrolene sodium intravenous for additional information on patient management). Renal failure may appear later, and urine flow should be sustained if possible.

PATIENT PACKAGE INSERT

During clinical development, the number of patients with myoclonic seizures exposed to Keppra was considerably smaller than the number with partial seizures. Therefore, under-reporting of certain adverse events was more likely to occur in the myoclonic seizure population. In adult and adolescent patients experiencing myoclonic seizures, Keppra is associated with somnolence and behavioral abnormalities. It is expected that the events seen in partial seizure patients would occur in patients with JME.....

Roferon-A (interferon alfa-2a, recombinant)

Please contact Hoffman- LaRoche, Inc. at 1-973-235-5000 for prescribing information.

WARNINGS
  • Infections
  • Pancreatitis

ADVERSE REACTIONS

  • Post-marketing
    • Metabolic and Nutritional
      • Hypertriglyceridemia/ Hyperlipidemia
Infections

While fever may be associated with the flu-like syndrome reported commonly during interferon therapy, other causes of high or persistent fever must be ruled out, particularly in patients with neutropenia. Serious and severe infections (bacterial, viral, fungal), some fatal, have been reported during treatment with alpha interferons including Roferon-A. Appropriate anti-infective therapy should be started immediately and discontinuation of therapy should be considered.

Pancreatitis

Pancreatitis has been observed in patients receiving alpha interferon treatment, including those who developed marked triglyceride elevations. In some cases, fatalities have been observed. Although a causal relationship to Roferon has not been established, marked triglyceride elevation is a risk factor for development of pancreatitis. Roferon should be suspended if symptoms or signs suggestive of pancreatitis are observed. In patients diagnosed with pancreatitis, discontinuation of therapy with Roferon should be considered.

WARNINGS
  • Perioperative Hyperkalemia
  • Malignant Hyperthermia

PRECAUTIONS

  • Initial Section

    • As with other halogenated anesthetic agents, Suprane (desflurane, USP) may cause sensitivity hepatitis in patients who have been sensitized by previous exposure to halogenated anesthetics.

ADVERSE REACTIONS

  • Adverse reactions reported only from post-marketing experience or in the literature, not seen in clinical trials, are considered rare and are italicized.
  • There have been rare post-marketing reports of hepatic failure and hepatic necrosis associated with the use of potent volatile anesthetic agents, including Suprane (desflurane, USP). Due to the spontaneous nature of these reports, the actual incidence and relationship of Suprane (desflurane, USP) to these events cannot be established with certainty.

WARNINGS/Perioperative Hyperkalemia

Use of inhaled anesthetic agents has been associated with rare increases in serum potassium levels that have resulted in cardiac arrhythmias and death in pediatric patients during the postoperative period. Patients with latent as well as overt neuromuscular disease, particularly Duchenne muscular dystrophy, appear to be most vulnerable. Concomitant use of succinylcholine has been associated with most, but not all, of these cases. These patients also experienced significant elevations in serum creatinine kinase levels and, in some cases, changes in urine consistent with myoglobinuria. Despite the similarity in presentation to malignant hyperthermia, none of these patients exhibited signs or symptoms of muscle rigidity or hypermetabolic state. Early and aggressive intervention to treat the hyperkalemia and resistant arrhythmias is recommended, as is subsequent evaluation for latent neuromuscular disease.

WARNINGS/Malignant Hyperthermia

In susceptible individuals, potent inhalation anesthetic agents may trigger a skeletal muscle hypermetabolic state leading to high oxygen demand and the clinical syndrome known as malignant hyperthermia. In genetically susceptible pigs, desflurane induced malignant hyperthermia. The clinical syndrome is signalled by hypercapnia, and may include muscle rigidity, tachycardia, tachypnea, cyanosis, arrhythmias, and/or unstable blood pressure. Some of these nonspecific signs may also appear during light anesthesia: acute hypoxia, hypercapnia, and hypovolemia.....

WARNINGS
  • Use with Interferon- and
    Ribavirin-Based Regimens
  • Other

MEDICATION GUIDE

WARNINGS/Use with Interferon- and Ribavirin-Based Regimens

In vitro studies have shown ribavirin can reduce the phosphorylation of pyrimidine nucleoside analogues such as lamivudine and zidovudine, components of Trizivir. Although no evidence of a pharmacokinetic or pharmacodynamic interaction (e.g., loss of HIV/HCV virologic suppression) was seen when ribavirin was coadministered with lamivudine or zidovudine in HIV/HCV co-infected patients, hepatic decompensation (some fatal) has occurred in HIV/HCV co-infected patients receiving combination antiretroviral therapy for HIV and interferon alfa with or without ribavirin. Patients receiving interferon alfa with or without ribavirin and Trizivir should be closely monitored for treatment-associated toxicities, especially hepatic decompensation, neutropenia, and anemia. Discontinuation of Trizivir should be considered as medically appropriate. Dose reduction or discontinuation of interferon alfa, ribavirin, or both should also be considered if worsening clinical toxicities are observed, including hepatic decompensation (e.g., Childs Pugh >6).....

WARNINGS/Other

Trizivir contains fixed doses of 3 nucleoside analogues.....

Videx (didanosine) Chewable/Dispersible Buffered Tablets

Videx (didanosine) Pediatric Powder for Oral Solution

(click product name to read prescribing information)

WARNINGS
  • Hepatic Impairment and Toxicity

PRECAUTIONS

  • Peripheral Neuropathy
    • .....Peripheral neuropathy, which was severe in some cases, has been reported in HIV-infected patients receiving hydroxyurea in combination with antiretroviral agents, including didanosine, with or without stavudine.
  • Immune Reconstitution Syndrome
  • Drug Interactions
    • Table 7: Established Drug Interactions with Videx
      • Tenofovir Disoproxil Fumarate
    • Nucleoside/nucleotide Analogues

ADVERSE REACTIONS

  • Initial Section

    • Hepatotoxicity and Severe Peripheral Neuropathy

It is unknown if hepatic impairment significantly affects didanosine pharmacokinetics. Therefore, these patients should be monitored closely for evidence of didanosine toxicity. The safety and efficacy of Videx have not been established in HIV-infected patients with significant underlying liver disease. During combination antiretroviral therapy, patients with preexisting liver dysfunction, including chronic active hepatitis, have an increased frequency of liver function abnormalities, including severe and potentially fatal hepatic adverse events, and should be monitored according to standard practice. If there is evidence of worsening liver disease in such patients, interruption or discontinuation of treatment must be considered.

Hepatotoxicity and hepatic failure resulting in death were reported during post-marketing surveillance in HIV-infected patients treated with hydroxyurea and other antiretroviral agents. Fatal hepatic events were reported most often in patients treated with the combination of hydroxyurea, didanosine, and stavudine. This combination should be avoided.
