Contraindications

4 CONTRAINDICATIONS Use of a long-acting beta 2 -adrenergic agonist (LABA), including formoterol fumarate, one of the active ingredients in DUAKLIR PRESSAIR, without an inhaled corticosteroid is contraindicated in patients with asthma [see Warnings and Precautions (5.1) ] . DUAKLIR PRESSAIR is not indicated for the treatment of asthma. DUAKLIR PRESSAIR is contraindicated in patients with: • Severe hypersensitivity to milk proteins [see Warnings and Precautions (5.5) ] . • Hypersensitivity to aclidinium bromide, formoterol fumarate, or to any component of the product [see Warnings and Precautions (5.5) ] . • Use of a long-acting beta 2 -adrenergic agonist (LABA), including formoterol fumarate, one of the active ingredients in DUAKLIR PRESSAIR, without an inhaled corticosteroid is contraindicated in patients with asthma. ( 1 , 4 ) • Hypersensitivity to aclidinium bromide or formoterol fumarate or to any component of this product. ( 4 , 5.5 )

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies of DUAKLIR PRESSAIR or its individual components, formoterol fumarate or aclidinium bromide, in pregnant women to inform drug-associated risks. No adverse developmental effects were seen with inhalation administration of aclidinium bromide to pregnant rats and rabbits during organogenesis at 15 or 20 times, respectively, the maximum recommended human daily inhaled dose (MRHDID). However, reduced pup weights were seen when pregnant rats continued inhalation administration through lactation at 5 times the MRHDID of aclidinium bromide. Adverse developmental effects occurred when rabbits were orally dosed with aclidinium bromide at approximately 1,400 times the MRHDID [see Data] . Formoterol fumarate alone, administered by the oral route, was teratogenic in rats and rabbits at 1,200 and 49,000 times the MRHDID, respectively. Formoterol fumarate was also embryocidal, increased pup loss at birth and during lactation, and decreased pup weight in rats at 85 times the MRHDID. These adverse effects generally occurred at large multiples of the MRHDID when formoterol fumarate was administered by the oral route to achieve high systemic exposures. No teratogenic, embryocidal, or developmental effects were seen in rats that received inhalation doses up to 280 times the MRHDID [ see Data ]. The estimated background risk of major birth defects and miscarriage of the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Labor or Delivery There are no well-controlled human studies that have investigated the effects of DUAKLIR PRESSAIR during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of DUAKLIR PRESSAIR during labor should be restricted to those patients in whom the
