What is brompheniramine?

Brompheniramine is an antihistamine. Brompheniramine blocks the effects of the naturally occurring chemical histamine in the body.


Brompheniramine is used to sneezing; runny nose; itching, watery eyes; hives; rashes; itching; and other symptoms of allergies and the common cold.


Brompheniramine may also be used for purposes other than those listed in this medication guide.


What is the most important information I should know about brompheniramine?


Use caution when driving, operating machinery, or performing other hazardous activities. Brompheniramine may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while taking brompheniramine. Do not crush, chew, or break the extended- or timed-release forms of brompheniramine. Swallow them whole. They are specially formulated to release the medication slowly in the body.

What should I discuss with my healthcare provider before taking brompheniramine?


Do not take brompheniramine if you have taken a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.

Before taking brompheniramine, talk to your doctor if you have



  • glaucoma or increased pressure in the eye;




  • a stomach ulcer;




  • an enlarged prostate, bladder problems or difficulty urinating;




  • an overactive thyroid (hyperthyroidism);




  • hypertension or any type of heart problems; or




  • asthma.



You may not be able to take brompheniramine, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.


Brompheniramine is in the FDA pregnancy category C. This means that it is not known whether brompheniramine will be harmful to an unborn baby. Do not take brompheniramine without first talking to your doctor if you are pregnant or could become pregnant during treatment. Brompheniramine passes into breast milk. Infants are especially sensitive to the effects of antihistamines, and serious side effects could occur in a nursing infant. Do not take brompheniramine without first talking to your doctor if you are nursing a baby. If you are over 60 years of age, you may be more likely to experience side effects from brompheniramine. You may require a lower dose of this medication.

How should I take brompheniramine?


Take brompheniramine exactly as directed on the package or as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.


Take each dose with a full glass of water.

Brompheniramine can be taken with or without food.


Do not crush, chew, or break the extended- or timed-release forms of brompheniramine. Swallow them whole. They are specially formulated to release the medication slowly in the body.

To ensure that you get a correct dose, measure the liquid form of brompheniramine with a special dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.


Do not take more of this medication than is prescribed or is recommended on the package. The maximum amount of brompheniramine that you should take in 1 day is 24 mg. The regular-release tablets and the syrup are usually taken every 4 to 6 hours as needed (four to six times a day). The sustained-release tablets and capsules are usually taken every 8 to 12 hours as needed (two or three times a day). If your symptoms do not improve, or if they worsen, contact your healthcare provider. Store brompheniramine at room temperature away from moisture and heat.

What happens if I miss a dose?


Take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose of this medication unless otherwise directed by your doctor.


What happens if I overdose?


Seek emergency medical attention if an overdose is suspected.

Symptoms of a brompheniramine overdose may include extreme sleepiness, confusion, weakness, ringing in the ears, blurred vision, large pupils, dry mouth, flushing, fever, shaking, insomnia, hallucinations, and possibly seizures.


What should I avoid while taking brompheniramine?


Do not take other over-the-counter cough, cold, allergy, diet, pain, or sleep medications while taking brompheniramine without first talking to your pharmacist or doctor. Other medications may also contain brompheniramine or other similar drugs, and you may accidentally take too much of these medicines.


Brompheniramine may increase the effects of other drugs that cause drowsiness, including antidepressants, alcohol, other antihistamines, pain relievers, anxiety medicines, seizure medicines, and muscle relaxants. Dangerous sedation, dizziness, or drowsiness may occur if brompheniramine is taken with any of these medications.


Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while taking brompheniramine.

Brompheniramine side effects


Stop taking brompheniramine and seek emergency medical attention if you experience a rare but serious allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives).

Other, less serious side effects may be more likely to occur. Continue to take brompheniramine and talk to your doctor if you experience



  • sleepiness, fatigue, or dizziness;




  • headache;




  • dry mouth; or




  • difficulty urinating or an enlarged prostate.



Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.

Lactation

Distributed into milk in rats; not known whether distributed into human milk.1 Use not recommended.1


Pediatric Use

Safety and efficacy not established in pediatric patients.1


Geriatric Use

Increased exposure to drug and active metabolite.1 (See Special Populations under Pharmacokinetics.) However, no overall differences in safety or efficacy relative to younger adults.1


Hepatic Impairment

Use with caution in patients with moderate hepatic impairment; avoid use in patients with severe hepatic impairment.1 (See Special Populations under Pharmacokinetics.)


Common Adverse Effects


Headache, somnolence, dizziness, fatigue, nausea, exacerbation of insomnia, upper respiratory tract infection, diarrhea, myalgia, depression, dysgeusia, arthralgia.1


Interactions for Ramelteon


Metabolized principally by CYP1A2 and, to a lesser extent, by the CYP2C subfamily and by CYP3A4.1


Drugs Affecting Hepatic Microsomal Enzymes


Inhibitors of CYP1A2: Potential pharmacokinetic interaction (substantially increased serum ramelteon concentrations).1 Avoid concomitant use with strong CYP1A2 inhibitors; caution if used concomitantly with less potent CYP1A2 inhibitors.1


Inhibitors of CYP3A4 and CYP2C9: Potential pharmacokinetic interaction (increased serum concentrations of ramelteon and active metabolite).1 Caution if used concomitantly with potent inhibitors of CYP3A4 or CYP2C9.1


Inducers of CYP isoenzymes: Potential pharmacokinetic interaction (decreased serum concentrations of ramelteon and active metabolite).1 Possibly reduced ramelteon efficacy when used concomitantly with potent CYP inducers.1 2


Drugs Metabolized by Hepatic Microsomal Enzymes


Substrates of CYP isoenzymes 1A2, 2C9, 2C19, 2D6, and 3A4: Pharmacokinetic interaction unlikely.1

Ramelteon Pharmacokinetics


Absorption


Bioavailability


Rapidly absorbed; following oral administration in fasting state, peak serum concentrations occur at approximately 0.75 hour.1


Total absorption is ≥84%; however, absolute oral bioavailability is 1.8% because of extensive first-pass metabolism.1


Food


High-fat meal delays time to peak serum concentration by 45 minutes, reduces peak serum concentration by 22%, and increases AUC by 31%.1 (See Oral Administration under Dosage and Administration.)


Special Populations


In geriatric patients, peak serum concentrations and AUC of ramelteon are increased by 86 and 97%, respectively.1 Peak serum concentrations and AUC of active metabolite also are increased, but to a lesser extent.1


In patients with mild or moderate hepatic impairment, exposure to ramelteon is increased 4- or 10-fold, respectively.1 Exposure to active metabolite is marginally increased.1 Pharmacokinetic parameters not evaluated in patients with severe hepatic impairment (Child-Pugh class C).1 (See Hepatic Impairment under Cautions.)


Pharmacokinetic parameters not altered in patients with renal impairment or in those requiring chronic hemodialysis.1


Distribution


Extent


Extensively distributed into tissues; not distributed selectively to red blood cells.1


Plasma Protein Binding


Approximately 82% (mainly [70%] albumin).1


Elimination


Metabolism


Metabolized principally by CYP1A2 and, to a lesser extent, by the CYP2C subfamily and by CYP3A4 to active (M-II) and inactive metabolites.1


Elimination Route


Excreted in urine (84%) and feces (4%), principally as metabolites.1


Half-life


1–2.6 hours (for ramelteon) and 2–5 hours (for active metabolite).1


Stability


Storage


Oral


Capsules

Tightly-closed containers at 25°C (may be exposed to 15–30°C).1 Protect from moisture and humidity.1


Actions



  • Exhibits high affinity for melatonin MT1 and MT2 receptors.1 2 Agonist activity at these receptors may contribute to the drug’s sleep-inducing properties.1 2




  • Demonstrates lower selectivity for melatonin MT3 receptors than for MT1 and MT2 receptors.1 Has no appreciable affinity for the GABA receptor complex or for receptors that bind neuropeptides, cytokines, serotonin, dopamine, norepinephrine, acetylcholine, or opiates.1



Advice to Patients



  • Necessity of administering within 30 minutes of bedtime and limiting activities to only those necessary to prepare for bed.1 Avoid administration with or immediately after a high-fat meal.1




  • Necessity of avoiding driving, operating machinery, or performing hazardous tasks following administration.1 Importance of avoiding alcohol during therapy.1




  • Importance of consulting a clinician if worsening insomnia or emergence of new behavioral manifestations occurs.1




  • Importance of consulting a clinician if cessation of menses or galactorrhea (in women), decreased libido, or problems with fertility occur.1




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.1




  • Importance of informing patients of other important precautionary information.1 (See Cautions.)

Mylotarg


Pronunciation: gem-TOO-zoo-mab oh-zoh-ga-MYE-sin
Generic Name: Gemtuzumab Ozogamicin
Brand Name: Mylotarg

Mylotarg should not be used along with other chemotherapy medicines. Severe bone marrow problems occur even at normal doses of Mylotarg. Severe and sometimes fatal allergic reactions and lung problems have occurred with use of Mylotarg. Tell the doctor immediately if you experience rash; hives; difficulty breathing; swelling of the mouth, face, lips, or tongue; or severe dizziness. Mylotarg may also increase the risk of severe and sometimes fatal liver problems. This risk may be increased if you have liver problems, you have had a hematopoietic stem-cell transplant (HSCT), or you use Mylotarg in combination with other chemotherapy medicines. Contact your doctor immediately if you experience sudden weight gain, right-sided stomach pain, stomach swelling, yellowing of the eyes or skin, or dark urine. Your doctor will monitor you closely while you use Mylotarg.





Mylotarg is used for:

Treating acute myeloid leukemia (AML) in patients 60 years of age and older who cannot take other cancer medications. It may also be used for other conditions as determined by your doctor.


Mylotarg is a chemotherapy agent. It works by binding to and breaking specific parts that the cancer cell needs to survive.


Do NOT use Mylotarg if:


  • you are allergic to any ingredient in Mylotarg

Contact your doctor or health care provider right away if any of these apply to you.

Introduction

Antiretroviral with antiviral activity against hepatitis B virus (HBV); nucleotide reverse transcriptase inhibitor.1 2 3 5


Uses for Tenofovir Disoproxil Fumarate


Treatment of HIV Infection


Treatment of HIV-1 infection in conjunction with other antiretrovirals.1 6


For purposes of therapeutic decisions, tenofovir is grouped with nucleoside reverse transcriptase inhibitor (NRTI) antiretrovirals.6


A preferred NRTI for use in multiple-drug antiretroviral regimens for initial therapy in adults.6


Fixed-combination preparation containing tenofovir and emtricitabine (Truvada) used in conjunction with other antiretrovirals.13 Can be used to decrease pill burden,6 but should not be used as a component of a triple NRTI regimen.13


Fixed-combination preparation containing efavirenz, emtricitabine, and tenofovir (Atripla) used alone or in conjunction with other antiretrovirals.22 Used to decrease pill burden and improve compliance.22


Because of a high rate of virologic failure, triple NRTI regimens of tenofovir, abacavir, and lamivudine or tenofovir, didanosine, and lamivudine not recommended.6 9 12 Because of high rates of early virologic failure and rapid selection of resistant mutations, a regimen of tenofovir and didanosine not recommended for initial therapy.6


For patients coinfected with HBV, some experts recommend an NRTI combination of tenofovir and (emtricitabine or lamivudine); avoid use of regimens containing only 1 of these antiretrovirals (may increase risk of HBV resistance).6


Postexposure Prophylaxis of HIV


Postexposure prophylaxis of HIV infection in health-care workers and others exposed occupationally via percutaneous injury or mucous membrane or nonintact skin contact with blood, tissues, or other body fluids associated with risk for transmission of the virus.20 Used in conjunction with other antiretrovirals.20


Postexposure prophylaxis of HIV infection in individuals who have had nonoccupational exposure to blood, genital secretions, or other potentially infectious body fluids of a person known to be infected with HIV when that exposure represents a substantial risk for HIV transmission.17 Used in conjunction with other antiretrovirals.17


Chronic HBV Infection


Management of chronic HBV infection in adults with compensated liver function.1


May be effective in both hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients.1 26


Safety and efficacy not established in patients with decompensated liver disease.1 Insufficient data in nucleoside-experienced patients and in those with lamivudine-associated mutations at study entry to establish efficacy in these patients.1


Patients coinfected with both HBV and HIV who require treatment for HBV and who are not receiving antiretroviral therapy should receive an antiviral agent for HBV infection that does not have activity against HIV.6 28


Tenofovir Disoproxil Fumarate Dosage and Administration


Administration


Oral Administration


Administer single-entity preparation (Viread) or fixed-combination preparation (Truvada) orally without regard to meals.1 6 13 Administer fixed-combination preparation (Atripla) orally once daily on an empty stomach, preferably at bedtime.22


Because dosage of tenofovir and emtricitabine cannot be adjusted individually, the fixed combination containing tenofovir and emtricitabine (Truvada) should not be used in pediatric patients or patients with severe renal impairment (Clcr <30 mL/minute).13


Because dosage of efavirenz, emtricitabine, and tenofovir cannot be adjusted individually, the fixed-combination containing efavirenz, emtricitabine, and tenofovir (Atripla) should not be used in patients with moderate to severe renal impairment (Clcr <50 mL/minute).22


Dosage


Available as tenofovir disodium fumarate; dosage expressed in terms of tenofovir disodium fumarate.1


Dosage of Truvada and Atripla expressed as number of tablets.13 22


For treatment of HIV infection, Viread and Truvada must be given in conjunction with other antiretrovirals.1 6 13 Atripla may be used alone or in conjunction with other antiretrovirals.22


If used with atazanavir, adjustment in treatment regimen necessary.10 If used with didanosine, adjustment of didanosine dosage necessary.1 6 (See Specific Drugs under Interactions.)

Warnings/Precautions


Warnings


Lactic Acidosis and Severe Hepatomegaly with Steatosis

Possible lactic acidosis and severe hepatomegaly with steatosis (potentially fatal).1 6 7 Reported mostly in women; obesity and long-term therapy with NRTIs also may be risk factors.1 6 Has been reported in patients with no known risk factors.1


Cautious use recommended in patients with known risk factors for liver disease.1


Interrupt therapy if there are clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (e.g., hepatomegaly and steatosis even in the absence of marked increases in serum aminotransferase concentrations).1


Exacerbation of Hepatitis

Severe acute exacerbations of hepatitis reported following discontinuance of HBV therapy in patients with HBV infection.1


Closely monitor hepatic function at repeated intervals with both clinical and laboratory follow-up for several months or longer after tenofovir is discontinued.1 If appropriate, resumption of anti-HBV therapy may be warranted.1


Patients Coinfected with HBV and HIV

Test all HIV-infected patients for presence of HBV before initiating tenofovir.1


Test all HBV-infected patients for HIV before initiating tenofovir.1


Use tenofovir with other highly active antiretroviral agents in individuals coinfected with HBV and HIV.1


Renal Toxicity

Renal impairment, including acute renal failure and Fanconi syndrome (renal tubular injury with hypophosphatemia) reported.1


Avoid use in patients who are or have recently received nephrotoxic drugs.1


Obtain Clcr before starting tenofovir; monitor periodically thereafter.1 Monitor Clcr and serum phosphorus in those at risk for renal dysfunction.1


General Precautions


Do not use multiple tenofovir-containing preparations concomitantly.1


Use of Fixed Combinations

When used in fixed combination with emtricitabine (Truvada), consider the cautions, precautions, and contraindications associated with emtricitabine.13


When used in fixed combination with emtricitabine and efavirenz (Atripla), consider the cautions, precautions, and contraindications associated with the concomitant agents.22


Adipogenic Effects

Possible redistribution or accumulation of body fat, including central obesity, dorsocervical fat enlargement (“buffalo hump”), peripheral wasting, facial wasting, breast enlargement, and general cushingoid appearance.1


Immune Reconstitution Syndrome

During initial treatment, patients who respond to antiretroviral therapy may develop an inflammatory response to indolent or residual opportunistic infections (e.g., Mycobacterium avium complex [MAC], M. tuberculosis, cytomegalovirus [CMV], Pneumocystis jiroveci [formerly P. carinii]); this may necessitate further evaluation and treatment.1


Bone Effects

Decreases from baseline in bone mineral density (BMD) at lumbar spine and hip, increases in biochemical markers of bone metabolism, and increased serum parathyroid hormone reported in patients receiving tenofovir with lamivudine and efavirenz; clinical importance unclear.1


Osteomalacia associated with proximal renal tubulopathy reported during postmarketing surveillance.1


Consider supplementation with calcium or vitamin D; the effect of such supplementation has not been studied.1


Consider monitoring BMD in those with a history of pathologic bone fracture and in those at substantial risk for osteopenia.1 If bone abnormalities are suspected, obtain appropriate consultation.1


Early Virologic Failure in HIV Infection

Triple NRTI regimens associated with early virologic failure and high rates of resistance.1 Use with caution; consider modifying the regimen.1


Specific Populations


Pregnancy

Category B.1 Antiretroviral Pregnancy Registry at 800-258-4263.1 18


Because of lack of data and concerns regarding potential fetal bone effects, experts recommend the drug be used in pregnant women only after careful consideration of other alternatives.18


Lactation

Distributed into milk in rats; not known whether distributed into human milk.1


Instruct HIV-infected women not to breast-feed because of risk of HIV transmission and risk of adverse effects in the infant.1


Pediatric Use

Safety and efficacy of single entity (Viread) or fixed-combination (Truvada, Atripla) not established in children1 15 <18 years of age.1 7 22


Clinical studies underway to evaluate investigational tablets and oral solution of tenofovir in HIV-infected children ≥2 years of age.15


Geriatric Use

Insufficient experience in those ≥65 years of age to determine whether they respond differently than younger adults; select dosage with caution.1


Hepatic Impairment

Limited data indicate dosage adjustment not needed in patients with hepatic impairment.1


Renal Impairment

Tenofovir principally eliminated by kidneys; pharmacokinetics likely to be affected.1


Monitor Clcr and serum phosphorus in patients with mild renal impairment (Clcr 50–80 mL/minute).1


Dosage adjustments necessary in those with Clcr <50 mL/minute.1 6 Closely monitor clinical response and renal function; safety and efficacy of reduced dosages not evaluated in clinical studies.1 (See Renal Impairment under Dosage and Administration.)


Common Adverse Effects


HIV Infection: Nausea, diarrhea, rash, headache, pain, depression, asthenia.1


HBV Infection: Nausea.1


Interactions for Tenofovir Disoproxil Fumarate


Tenofovir and its prodrug are not substrates of CYP enzymes;1 tenofovir does not inhibit CYP3A4, 2D6, 2C9, or 2E1, but may have a slight inhibitory effect on 1A.1


Drugs Affecting or Metabolized by Hepatic Microsomal Enzymes


Pharmacokinetic interactions with drugs that are inhibitors or substrates of hepatic microsomal enzymes unlikely.1


Nephrotoxic Drugs or Drugs Eliminated by Renal Excretion


Potential increased plasma concentrations of tenofovir or the concomitant drug when used with drugs that reduce renal function or compete for active tubular secretion (e.g., acyclovir, adefovir dipivoxil, cidofovir, ganciclovir, valacyclovir, valganciclovir).1 Monitor for dose-related toxicities.6

Tenofovir disoproxil fumarate requires initial diester hydrolysis for conversion to tenofovir and subsequent phosphorylation by cellular enzymes to form the active tenofovir diphosphate.1


Tenofovir and its prodrug are not substrates of CYP enzymes.1


Elimination Route


Eliminated principally by kidneys using glomerular filtration and active tubular secretion; approximately 32% of an oral dose excreted in urine within 24 hours.1


Half-life


Approximately 17 hours.1


Special Populations


No substantial changes in tenofovir pharmacokinetics in individuals with moderate to severe hepatic impairment compared with those with normal hepatic function.1


Moderate or severe renal impairment results in increased plasma concentrations; dosage adjustment necessary if Clcr <50 mL/minute.1 (See Renal Impairment under Dosage and Administration.)

Actions and SpectrumActions



  • Tenofovir disoproxil fumarate is a prodrug and is inactive until the drug is hydrolyzed in vivo to tenofovir which is then phosphorylated to the active metabolite (tenofovir diphosphate).1 2 3 5




  • Active in vitro and in vivo against HIV-11 5 and HBV;1 6 26 some activity against HIV-2.1




  • Inhibits replication of retroviruses, including HIV-1, by interfering with viral RNA-directed DNA polymerase (reverse transcriptase).1 2 3 5




  • Inhibits HBV replication through competitive inhibition of viral DNA polymerase.29




  • Weak inhibitor of mammalian DNA α- and β-polymerases and mitochondrial DNA γ-polymerase.1 4 5 Low potential to induce mitochondrial toxicity.4 5




  • HIV-1 resistant to tenofovir can be selected in vitro and have been reported in clinical isolates.1 5




  • Cross-resistance between tenofovir and some NRTIs reported.1 Cross-resistance with HIV protease inhibitors (PIs) or nonnucleoside reverse transcriptase inhibitors (NNRTIs) unlikely.7



Advice to Patients



  • Critical nature of HIV therapy compliance.1 Importance of using tenofovir in conjunction with other antiretrovirals—not for monotherapy.1




  • Antiretroviral therapy is not a cure for HIV infection, and opportunistic infections still may occur.1 HIV transmission via sexual contact or sharing needles is not prevented by antiretrovirals.1




  • Advise patient of the risks and benefits of tenofovir and other alternatives for treatment of HBV infection.1




  • Importance of reading patient package insert from manufacturer.1




  • Redistribution/accumulation of body fat may occur, with as yet unknown long-term health effects.1




  • Importance of informing clinicians of concomitant medical problems such as renal or hepatic impairment.1




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and dietary or herbal products.1




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of advising patients of other important precautionary information.1 (See Cautions.)
