(ipratropium bromide and albuterol sulfate)
(Ipratropium Bromide 0.5 mg/Albuterol Sulfate 3.0 mg*)Inhalation Solution
*Equivalent to 2.5 mg albuterol base
The active components in DuoNeb® Inhalation Solution are albuterol sulfate and ipratropium bromide.
Albuterol sulfate, is a salt of racemic albuterol and a relatively selective β2-adrenergic bronchodilator chemically described as α1-[(tert-butylamino)methyl]-4-hydroxy-m-xylene-α, α'-diol sulfate (2:1) (salt). It has a molecular weight of 576.7 and the empirical formula is (C13H21NO3)2•H2SO4. It is a white crystalline powder, soluble in water and slightly soluble in ethanol. The World Health Organization recommended name for albuterol base is salbutamol.
Figure 3. 1-1. Chemical structure of albuterol sulfate.
Ipratropium bromide is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo [3.2.1]-octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8methyl-8-(1-methylethyl)-, bromide, monohydrate (endo, syn)-, (±)-; a synthetic quaternary ammonium compound, chemically related to atropine. It has a molecular weight of 430.4 and the empirical formula is C20H30BrNO3•H2O. It is a white crystalline substance, freely soluble in water and lower alcohols, and insoluble in lipophilic solvents such as ether, chloroform, and fluorocarbons.
Figure 3. 1-2. Chemical structure of ipratropium bromide.
Each 3 mL vial of DuoNeb contains 3.0 mg (0.1%) of albuterol sulfate (equivalent to 2.5 mg (0.083%) of albuterol base) and 0.5 mg (0.017%) of ipratropium bromide in an isotonic, sterile, aqueous solution containing sodium chloride, hydrochloric acid to adjust to pH 4, and edetate disodium, USP (a chelating agent).
DuoNeb is a clear, colorless solution. It does not require dilution prior to administration by nebulization. For DuoNeb Inhalation Solution, like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the jet nebulizer utilized, and compressor performance. Using the Pari-LC-Plus™ nebulizer (with face mask or mouthpiece) connected to a PRONEB™ compressor system, under in vitro conditions, the mean delivered dose from the mouth piece (% nominal dose) was approximately 46% of albuterol and 42% of ipratropium bromide at a mean flow rate of 3.6 L/min. The mean nebulization time was 15 minutes or less. DuoNeb should be administered from jet nebulizers at adequate flow rates, via face masks or mouthpieces (see DOSAGE AND ADMINISTRATION).
DuoNeb Inhalation Solution is a combination of the β2-adrenergic bronchodilator, albuterol sulfate, and the anticholinergic bronchodilator, ipratropium bromide.
Mechanism of Action
The prime action of β-adrenergic drugs is to stimulate adenyl cyclase, the enzyme that catalyzes the formation of cyclic-3',5'-adenosine monophosphate (cAMP) from adenosine triphosphate (ATP). The cAMP thus formed mediates the cellular responses. In vitro studies and in vivo pharmacologic studies have demonstrated that albuterol has a preferential effect on β2-adrenergic receptors compared with isoproterenol. While it is recognized that β2-adrenergic receptors are the predominant receptors in bronchial smooth muscle, recent data indicated that 10% to 50% of the β-receptors in the human heart may be β2-receptors. The precise function of these receptors, however, is not yet established. Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other β-adrenergic agonist drugs, can produce a significant cardiovascular effect in some patients.
Albuterol sulfate is longer acting than isoproterenol in most patients by any route of administration, because it is not a substrate for the cellular uptake processes for catecholamine nor for the metabolism of catechol-O-methyl transferase. Instead the drug is conjugatively metabolized to albuterol 4'-O-sulfate.
Intravenous studies in rats with albuterol sulfate have demonstrated that albuterol crosses the blood-brain barrier and reaches brain concentrations amounting to approximately 5% of plasma concentrations. In structures outside of the blood-brain barrier (pineal and pituitary glands), albuterol concentrations were found to be 100 times those found in whole brain.
Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrythmias and sudden death (with histological evidence of myocardial necrosis) when beta-agonists and methyl-xanthines are administered concurrently. The clinical significance of these findings is unknown.
Mechanism of Action
Ipratropium bromide is an anticholinergic (parasympatholytic) agent, which blocks the muscarinic receptors of acetylcholine, and, based on animal studies, appears to inhibit vagally mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released from the vagus nerve. Anticholinergics prevent the increases in intracellular concentration of cyclic guanosine monophosphate (cGMP), resulting from the interaction of acetylcholine with the muscarinic receptors of bronchial smooth muscle.
The bronchodilation following inhalation of ipratropium is primarily a local, site-specific effect, not a systemic one. Much of an inhaled dose is swallowed as shown by fecal excretion studies. Following nebulization of a 1-mg dose to healthy volunteers, a mean of 4% of the dose was excreted unchanged in the urine.
Ipratropium bromide is minimally (0% to 9% in vitro) bound to plasma albumin and α1-acid glycoproteins. It is partially metabolized to inactive ester hydrolysis products. Following intravenous administration, approximately one-half is excreted unchanged in the urine. The half-life of elimination is about 1.6 hours after intravenous administration. Ipratropium bromide that reaches the systemic circulation is reportedly removed by the kidneys rapidly at a rate that exceeds the glomerular filtration rate. The pharmacokinetics of DuoNeb Inhalation Solution or ipratropium bromide have not been studied in the elderly and in patients with hepatic or renal insufficiency (see PRECAUTIONS).
Mechanism of Action
DuoNeb is expected to maximize the response to treatment in patients with chronic obstructive pulmonary disease (COPD) by reducing bronchospasm through two distinctly different mechanisms: sympathomimetic (albuterol sulfate) and anticholinergic/parasympatholytic (ipratropium bromide). Simultaneous administration of both an anticholinergic and a β2-sympathomimetic is designed to produce greater bronchodilation effects than when either drug is utilized alone at its recommended dosage.
In 30-day studies in Sprague-Dawley rats and Beagle dogs, subcutaneous doses of up to 205.5 mcg/kg of ipratropium administered with up to 1000 mcg/kg albuterol in rats and 3.16 mcg/kg ipratropium and 15 mcg/kg albuterol in dogs (less than the maximum recommended daily inhalation dose for adults on a mg/m2 basis) did not cause death or potentiation of the cardiotoxicity induced by albuterol administered alone.
In a double blind, double period, crossover study, 15 male and female subjects were administered single doses of DuoNeb or albuterol sulfate inhalation solution at two times the recommended single doses as two inhalations separated by 15 minutes. The total nebulized dose of albuterol sulfate from both treatments was 6.0 mg and the total dose of ipratropium bromide from DuoNeb was 1.0 mg. Peak albuterol plasma concentrations occurred at 0.8 hours after dosing for both treatments. The mean peak albuterol concentration following administration of albuterol sulfate alone was 4.86 (± 2.65) mg/mL and it was 4.65 (± 2.92) mg/mL for DuoNeb. Mean AUC values for the two treatments were 26.6 (± 15.2) ng∙hr/mL (albuterol sulfate alone) versus 24.2 (± 14.5) ng∙hr/mL (DuoNeb). The mean t1/2 values were 7.2 (± 1.3) hours (albuterol sulfate alone) and 6.7 (± 1.7) hours (DuoNeb). A mean of 8.4 (± 8.9)% of the albuterol dose was excreted unchanged in urine following administration of two vials of DuoNeb which is similar to 8.8 (± 7.3)% that was obtained from albuterol sulfate inhalation solution. There were no statistically significant differences in the pharmacokinetics of albuterol between the two treatments. For ipratropium, a mean of 3.9 (± 5.1)% of the ipratropium bromide dose was excreted unchanged in urine following two vials of DuoNeb Inhalation Solution, which is comparable with previously reported data.
In a 12 week, randomized, double-blind, positive-control, crossover study of albuterol sulfate, ipratropium bromide, and DuoNeb, 863 COPD patients were evaluated for bronchodilator efficacy comparing DuoNeb with albuterol sulfate and ipratropium bromide alone.
DuoNeb demonstrated significantly better changes in FEV1, as measured from baseline to peak response, when compared with either albuterol sulfate or ipratropium bromide. DuoNeb was also shown to have the rapid onset associated with albuterol sulfate, with a mean time to peak FEV1 of 1.5 hours, and the extended duration associated with ipratropium bromide with a duration of 15% response in FEV1 of 4.3 hours.
Figure 3. 1-3. Mean Change in FEV<sub>1</sub> - Measured on Day 14
This study demonstrated that each component of DuoNeb contributed to the improvement in pulmonary function, especially during the first 4 to 5 hours after dosing, and that DuoNeb was significantly more effective than albuterol sulfate or ipratropium bromide alone.
INDICATIONS AND USAGE
DuoNeb is indicated for the treatment of bronchospasm associated with COPD in patients requiring more than one bronchodilator.
DuoNeb is contraindicated in patients with a history of hypersensitivity to any of its components, or to atropine and its derivatives.
In the clinical study of DuoNeb, paradoxical bronchospasm was not observed. However, paradoxical bronchospasm has been observed with both inhaled ipratropium bromide and albuterol products and can be life-threatening. If this occurs, DuoNeb should be discontinued immediately and alternative therapy instituted.
Do Not Exceed Recommended Dose
Fatalities have been reported in association with excessive use of inhaled products containing sympathomimetic amines and with the home use of nebulizers.
DuoNeb, like other beta adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon for DuoNeb at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta agonists have been reported to produce ECG changes, such as flattening of the T-wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, DuoNeb, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
1. Effects Seen with Sympathomimetic Drugs
As with all products containing sympathomimetic amines, DuoNeb should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension; in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus; and in patients who are unusually responsive to sympathomimetic amines. Large doses of intravenous albuterol have been reported to aggravate pre-existing diabetes mellitus and ketoacidosis. Additionally, β-agonists may cause a decrease in serum potassium in some patients, possibly through intracellular shunting. The decrease is usually transient, not requiring supplementation.
2. Effects Seen with Anticholinergic Drugs
Due to the presence of ipratropium bromide in DuoNeb, it should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, or bladder-neck obstruction.
Information for Patients
The action of DuoNeb should last up to 5 hours. DuoNeb should not be used more frequently than recommended. Patients should be instructed not to increase the dose or frequency of DuoNeb without consulting their healthcare provider. If symptoms worsen, patients should be instructed to seek medical consultation.
Patients must avoid exposing their eyes to this product as temporary pupillary dilation, blurred vision, eye pain, or precipitation or worsening of narrow-angle glaucoma may occur, and therefore proper nebulizer technique should be assured, particularly if a mask is used.
If a patient becomes pregnant or begins nursing while on DuoNeb, they should contact their healthcare provider about use of DuoNeb.
See the illustrated Patient's Instruction for Use in the product package insert.
Although ipratropium bromide is minimally absorbed into the systemic circulation, there is some potential for an additive interaction with concomitantly used anticholinergic medications. Caution is, therefore, advised in the co-administration of DuoNeb with other drugs having anticholinergic properties.
Caution is advised in the co-administration of DuoNeb and other sympathomimetic agents due to the increased risk of adverse cardiovascular effects.
ß-receptor blocking agents
These agents and albuterol sulfate inhibit the effect of each other. β-receptor blocking agents should be used with caution in patients with hyperreactive airways, and if used, relatively selective β1 selective agents are recommended.
The electrocardiogram (ECG) changes and/or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by β-agonists, especially when the recommended dose of the β-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of β-agonist-containing drugs, such as DuoNeb, with non-potassium sparing diuretics.
Monoamine oxidase inhibitors or tricyclic antidepressants
DuoNeb should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents because the action of albuterol sulfate on the cardiovascular system may be potentiated.
Carcinogenesis, Mutagenesis, Impairment of Fertility
In a 2-year study in Sprague-Dawley rats, albuterol sulfate caused a significant dose-related increase in the incidence of benign leiomyomas of the mesovarium at and above dietary doses of 2 mg/kg (approximately equal to the maximum recommended daily inhalation dose for adults on a mg/m2 basis). In another study, this effect was blocked by the coadministration of propranolol, a non-selective beta-adrenergic antagonist.
In an 18-month study in CD-1 mice, albuterol sulfate showed no evidence of tumorigenicity at dietary doses up to 500 mg/kg (approximately 140 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis). In a 22-month study in Golden hamsters, albuterol sulfate showed no evidence of tumorigenicity at dietary doses up to 50 mg/kg (approximately 20 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis).
Albuterol sulfate was not mutagenic in the Ames test or a mutation test in yeast. Albuterol sulfate was not clastogenic in a human peripheral lymphocyte assay or in an AH1 strain mouse micronucleous assay.
Reproduction studies in rats demonstrated no evidence of impaired fertility at oral doses of albuterol sulfate up to 50 mg/kg (approximately 25 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis).
In 2-year studies in Sprague-Dawley rats and CD-1 mice, ipratropium bromide showed no evidence of tumorigenicity at oral doses up to 6 mg/kg (approximately 15 times and 8 times the maximum recommended daily inhalation dose for adults in rats and mice respectively, on a mg/m2 basis).
Ipratropium bromide was not mutagenic in the Ames test and mouse dominant lethal test. Ipratropium bromide was not clastogenic in a mouse micronucleous assay.
A reproduction study in rats demonstrated decreased conception and increased resorptions when ipratropium bromide was administered orally at a dose of 90 mg/kg (approximately 240 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis). These effects were not seen with a dose of 50 mg/kg (approximately 140 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis).
TERATOGENIC EFFECTS: Pregnancy Category C
Pregnancy Category C
Albuterol sulfate has been shown to be teratogenic in mice. A study in CD-1 mice given albuterol sulfate subcutaneously showed cleft palate formation in 5 of 111 (4.5%) fetuses at 0.25 mg/kg (less than the maximum recommended daily inhalation dose for adults on a mg/m2 basis) and in 10 of 108 (9.3%) fetuses at 2.5 mg/kg (approximately equal to the maximum recommended daily inhalation dose for adults on a mg/m2 basis). The drug did not induce cleft palate formation when administered subcutaneously at a dose of 0.025 mg/kg (less than the maximum recommended daily inhalation dose for adults on a mg/m2 basis). Cleft palate formation also occurred in 22 of 72 (30.5%) fetuses from females treated subcutaneously with 2.5 mg/kg isoproterenol (positive control).
A reproduction study in Stride rabbits revealed cranioschisis in 7 of 19 (37%) fetuses when albuterol was administered orally at a dose of 50 mg/kg (approximately 55 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis).
A study in which pregnant rats were dosed with radiolabeled albuterol sulfate demonstrated that drug-related material is transferred from the maternal circulation to the fetus.
During worldwide marketing experience, various congenital anomalies, including cleft palate and limb defects, have been reported in the offspring of patients being treated with albuterol. Some of the mothers were taking multiple medications during their pregnancies. Because no consistent pattern of defects can be discerned, a relationship between albuterol use and congenital anomalies has not been established.
Pregnancy Category B
Reproduction studies in CD-1 mice, Sprague-Dawley rats and New Zealand rabbits demonstrated no evidence of teratogenicity at oral doses up to 10, 100, and 125 mg/kg, respectively (approximately 15, 270, and 680 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis). Reproduction studies in rats and rabbits demonstrated no evidence of teratogenicity at inhalation doses up to 1.5 and 1.8 mg/kg, respectively (approximately 4 and 10 times the maximum recommended daily inhalation dose for adults on a mg/m2 basis). There are no adequate and well-controlled studies of the use of DuoNeb, albuterol sulfate, or ipratropium bromide in pregnant women. DuoNeb should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Labor and Delivery
Oral albuterol sulfate has been shown to delay preterm labor in some reports. Because of the potential of albuterol to interfere with uterine contractility, use of DuoNeb during labor should be restricted to those patients in whom the benefits clearly outweigh the risks.
It is not known whether the components of DuoNeb are excreted in human milk. Although lipid-insoluble quaternary bases pass into breast milk, it is unlikely that ipratropium bromide would reach the infant to an important extent, especially when taken as a nebulized solution. Because of the potential for tumorigenicity shown for albuterol sulfate in some animals, a decision should be made whether to discontinue nursing or discontinue DuoNeb, taking into account the importance of the drug to the mother.
The safety and effectiveness of DuoNeb in patients below 18 years of age have not been established.
Of the total number of subjects in clinical studies of DuoNeb, 62 percent were 65 and over, while 19 percent were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
Adverse reaction information concerning DuoNeb was derived from the 12-week controlled clinical trial.

Additional adverse reactions reported in more than 1% of patients treated with DuoNeb included constipation and voice alterations.
In the clinical trial, there was a 0.3% incidence of possible allergic-type reactions, including skin rash, pruritus, and urticaria.
Additional information derived from the published literature on the use of albuterol sulfate and ipratropium bromide singly or in combination includes precipitation or worsening of narrow-angle glaucoma, acute eye pain, blurred vision, mydriasis, paradoxical bronchospasm, wheezing, exacerbation of COPD symptoms, drowsiness, aching, flushing, upper respiratory tract infection, palpitations, taste perversion, elevated heart rate, sinusitis, back pain, sore throat, and metabolic acidosis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The effects of overdosage with DuoNeb are expected to be related primarily to albuterol sulfate, since ipratropium bromide is not well-absorbed systemically after oral or aerosol administration. The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of symptoms such as seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmia, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, and exaggeration of pharmacological effects listed in ADVERSE REACTIONS. Hypokalemia may also occur. As with all sympathomimetic aerosol medications, cardiac arrest and even death may be associated with abuse of DuoNeb. Treatment consists of discontinuation of DuoNeb together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of DuoNeb.
The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 540 times the maximum recommended daily inhalation dose of DuoNeb on a mg/m2 basis). The subcutaneous median lethal dose of albuterol sulfate in mature rats and small young rats is approximately 450 and 2000 mg/kg respectively (approximately 240 and 1100 times the maximum recommended daily inhalation dose of DuoNeb on a mg/m2 basis, respectively). The inhalation median lethal dose has not been determined in animals. The oral median lethal dose of ipratropium bromide in mice, rats and dogs is greater than 1000 mg/kg, approximately 1700 mg/kg and approximately 400 mg/kg, respectively (approximately 1400, 4600, and 3600 times the maximum recommended daily inhalation dose in adults on a mg/m2 basis, respectively).
DOSAGE AND ADMINISTRATION
The recommended dose of DuoNeb is one 3 mL vial administered 4 times per day via nebulization with up to 2 additional 3 mL doses allowed per day, if needed. Safety and efficacy of additional doses or increased frequency of administration of DuoNeb beyond these guidelines has not been studied and the safety and efficacy of extra doses of albuterol sulfate or ipratropium bromide in addition to the recommended doses of DuoNeb have not been studied.
The use of DuoNeb can be continued as medically indicated to control recurring bouts of bronchospasm. If a previously effective regimen fails to provide the usual relief, medical advice should be sought immediately, as this is often a sign of worsening COPD, which would require reassessment of therapy.
A Pari-LC-Plus™ nebulizer (with face mask or mouthpiece) connected to a PRONEB™ compressor was used to deliver DuoNeb to each patient in one U.S. clinical study. The safety and efficacy of DuoNeb delivered by other nebulizers and compressors have not been established.
DuoNeb should be administered via jet nebulizer connected to an air compressor with an adequate air flow, equipped with a mouthpiece or suitable face mask.

Read the patient information that comes with DuoNeb® before you start using it and each time you get a refill. There may be new information. This leaflet does not take the place of talking with your doctor about your medical condition or your treatment.
What is DuoNeb®?
DuoNeb® is a combination of two medicines called bronchodilators. DuoNeb® contains albuterol sulfate, which is a beta-adrenergic agonist, and ipratropium bromide, which is an anticholinergic. These two medicines work together to help open the airways in your lungs. DuoNeb® is used to help treat airway narrowing (bronchospasm) that happens with chronic obstructive pulmonary disease (COPD) in adult patients who need to use more than one bronchodilator medicine.
Who should not use DuoNeb®?
Do not use DuoNeb® if you:Are allergic to any of the ingredients in DuoNeb or to atropine. The active ingredients are albuterol sulfate and ipratropium bromide. See the end of this leaflet for a complete list of ingredients in DuoNeb®.
DuoNeb® has not been studied in patients younger than 18 years of age.
What should I tell my doctor before I start using DuoNeb®?

- Have heart problems. This includes coronary artery disease and heart rhythm problems.
- Have high blood pressure
- Have diabetes
- Have or had seizures
- Have a thyroid problem called hyperthyroidism
- Have an eye problem called narrow-angle glaucoma
- Have liver or kidney problems
- Have problems urinating due to bladder-neck blockage or an enlarged prostate (men)
- Are pregnant or planning to become pregnant. It is not known if DuoNeb® can harm your unborn baby. You and your doctor will have to decide if DuoNeb® is right for you during a pregnancy.
- Are breastfeeding. It is not known if DuoNeb® passes into your milk or if it can harm your baby. You and your doctor should decide whether you should take DuoNeb® or breastfeed, but not both.
Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins and herbal supplements. DuoNeb® and other medicines can interact. This may cause serious side effects. Especially tell your doctor if you take:
- Other medicines that contain anticholinergics such as ipratropium bromide. This also includes medicines used for Parkinson's disease.
- Other medicines that contain beta-agonists such as albuterol sulfate. These are usually used to treat airway narrowing (bronchospasm).
- Medicines called beta-blockers. These are usually used for high blood pressure or heart problems.
- Medicines called "water pills" (diuretics)
- Medicines for depression called monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants.
Ask your doctor or pharmacist if you are not sure if you take any of these types of medicines. Know the medicines you take. Keep a list of them and show it to your doctor and pharmacists when you get a new medicine.
How should I use DuoNeb®?
- Read the Patient's Instructions for Use that you get with your prescription. Talk to your doctor or pharmacist if you have any questions.
- Take DuoNeb® exactly as prescribed by your doctor. Do not change your dose or how often you use DuoNeb® without talking to your doctor. Inhale DuoNeb® through your mouth and into your lungs using a machine called a nebulizer.
- DuoNeb® may help to open your airways for up to 5 hours after taking this medicine. If DuoNeb® does not help your airway narrowing (bronchospasm) or your bronchospasm gets worse, call your doctor right away or get emergency help if needed.
What should I avoid while using DuoNeb®?
Do not get DuoNeb® in your eyes. Be careful not to spray DuoNeb® in your eyes while you are using your nebulizer. DuoNeb® can cause the following short-term eye problems:
