11 DESCRIPTION Scopolamine transdermal system is designed for continuous release of scopolamine following application to an area of intact skin on the head, behind the ear. Each system contains 1.3 mg of scopolamine base. Scopolamine is (9-methyl-3-oxa-9-azatricyclo [3.3.1.0 2,4 ]nonan-7-yl) 3-hydroxy-2-phenylpropanoate. The empirical formula is C 17 H 21 NO 4 and its structural formula is: Scopolamine has a molecular weight of 303.35 and a pKa of 7.55 to 7.81. The scopolamine transdermal system is a circular, 0.28 mm thick, 2.5 cm 2 film with four layers. Proceeding from the visible surface towards the surface attached to the skin, these layers are: (1) a backing membrane of tan-colored, aluminized, polyester film; (2) a drug layer of scopolamine, light mineral oil, isopropyl palmitate, crospovidone, and polyisobutylene; (3) a microporous polypropylene membrane that controls the rate of delivery of scopolamine from the system to the skin surface; and (4) a contact layer formulation of mineral oil, polyisobutylene, isopropyl palmitate, crospovidone, and scopolamine. A release liner of siliconized polyester, which covers the adhesive layer, is removed before the system is used. Cross section of the system: Chemical Structure Image

2 DOSAGE AND ADMINISTRATION Application and Removal ( 2.1 ) Each scopolamine transdermal system delivers 1 mg of scopolamine over 3 days. Only wear one transdermal system at a time. Do not cut the transdermal system. Wash hands thoroughly with soap and water after application. Avoid touching or applying pressure to the transdermal system once applied. Upon removal, fold used transdermal system in half with sticky side together, discard to prevent accidental contact or ingestion, and wash the hands and application site with soap and water. Recommended Dosage: Motion Sickness: Apply one transdermal system to the hairless area behind one ear at least 4 hours before antiemetic effect is required for use up to 3 days. If therapy for more than 3 days is required, remove the first transdermal system and apply a new transdermal system behind the other ear. ( 2.2 ) PONV : For surgeries other than cesarean section, apply one transdermal system behind the ear the evening before surgery and remove 24 hours following surgery. ( 2.2 ) 2.1 Important Application and Removal Instructions Each scopolamine transdermal system is formulated to deliver in vivo approximately 1 mg of scopolamine over 3 days. Only wear one transdermal system at any time. Do not cut the transdermal system. Apply the transdermal system to the skin in the postauricular area (hairless area behind one ear). After the transdermal system is applied on the dry skin behind the ear, wash hands thoroughly with soap and water and dry hands [see Warnings and Precautions (5.6) ] . If the transdermal system becomes displaced, discard the transdermal system, and apply a new transdermal system on the hairless area behind the other ear. Once the transdermal system has been affixed, avoid touching or applying pressure to the transdermal system while it is being worn, since pressure exerted on it may cause scopolamine to ooze out at the edge. Upon removal, fold the used transdermal system in half with the sticky side together, and discard in household trash in a manner that prevents accidental contact or ingestion by children, pets, or others. Wash the hands and application site with soap and water after transdermal system removal [see Warnings and Precautions (5.6) ]. 2.2 Recommended Adult Dosage Motion Sickness Apply one scopolamine transdermal system to the hairless area behind one ear at least 4 hours before the antiemetic effect is required – for use up to 3 days. If therapy is required for longer than 3 days, remove the first transdermal system and apply a new scopolamine transdermal system behind the other ear. PONV For surgeries other than cesarean section : Apply one scopolamine transdermal system the evening before scheduled surgery. Remove the transdermal system 24 hours following surgery.

9.1 Controlled Substance Scopolamine transdermal system contains scopolamine, which is not a controlled substance.

9.3 Dependence Termination of scopolamine transdermal system, usually after several days of use, may result in withdrawal symptoms such as disturbances of equilibrium, dizziness, nausea, vomiting, abdominal cramps, sweating, headache, mental confusion, muscle weakness, bradycardia, and hypotension. These withdrawal symptoms indicate that scopolamine, like other anticholinergic drugs, may produce physical dependence. The onset of these symptoms, generally 24 hours or more after the transdermal system has been removed, can be severe and may require medical intervention [see Warnings and Precautions (5.5) ].

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Scopolamine transdermal system contains scopolamine, which is not a controlled substance. 9.3 Dependence Termination of scopolamine transdermal system, usually after several days of use, may result in withdrawal symptoms such as disturbances of equilibrium, dizziness, nausea, vomiting, abdominal cramps, sweating, headache, mental confusion, muscle weakness, bradycardia, and hypotension. These withdrawal symptoms indicate that scopolamine, like other anticholinergic drugs, may produce physical dependence. The onset of these symptoms, generally 24 hours or more after the transdermal system has been removed, can be severe and may require medical intervention [see Warnings and Precautions (5.5) ].

10 OVERDOSAGE The signs and symptoms of anticholinergic toxicity include lethargy, somnolence, coma, confusion, agitation, hallucinations, convulsion, visual disturbance, dry flushed skin, dry mouth, decreased bowel sounds, urinary retention, tachycardia, hypertension, and supraventricular arrhythmias. These symptoms can be severe and may require medical intervention. In cases of toxicity, remove the scopolamine transdermal system. Serious symptomatic cases of overdosage involving multiple transdermal system applications and/or ingestion may be managed by initially ensuring the patient has an adequate airway and supporting respiration and circulation. This should be rapidly followed by removal of all transdermal systems from the skin and the mouth. If there is evidence of transdermal system ingestion, endoscopic removal of swallowed transdermal systems, or administration of activated charcoal should be considered, as indicated by the clinical situation. In any case where there is serious overdosage or signs of evolving acute toxicity, continuous monitoring of vital signs and ECG, establishment of intravenous access, and administration of oxygen are all recommended. The signs and symptoms of overdose/toxicity due to scopolamine should be carefully distinguished from the occasionally observed syndrome of withdrawal [see Warnings and Precautions (5.5) ]. Although mental confusion and dizziness may be observed with both acute toxicity and withdrawal, other characteristic findings differ: tachyarrhythmias, dry skin, and decreased bowel sounds suggest anticholinergic toxicity, while bradycardia, headache, nausea and abdominal cramps, and sweating suggest post-removal withdrawal. If over-exposure occurs, call the Poison Help line at 1-800-222-1222 for current information on the management of poisoning or overdosage.

7 DRUG INTERACTIONS Drugs Causing Central Nervous System (CNS) Adverse Reactions : Monitor patients for CNS adverse reactions (drowsiness, dizziness, or disorientations). ( 7.1 ) Anticholinergic Drugs: Consider more frequent monitoring during treatment in patients receiving other anticholinergic drugs. ( 7.2 ) Oral Drugs Absorbed in the Stomach : Monitor for increased or decreased therapeutic effect of the oral drug. ( 7.3) Interaction with Gastric Secretion Test: Discontinue use of scopolamine transdermal system 10 days prior to testing. ( 7.4 ) 7.1 Drugs Causing Central Nervous System (CNS) Adverse Reactions The concurrent use of scopolamine transdermal system with other drugs that cause CNS adverse reactions of drowsiness, dizziness or disorientation (e.g., sedatives, hypnotics, opiates, anxiolytics, and alcohol) or have anticholinergic properties (e.g., other belladonna alkaloids, sedating antihistamines, meclizine, tricyclic antidepressants, and muscle relaxants) may potentiate the effects of scopolamine transdermal system [see Warnings and Precautions (5.2) ] . Either scopolamine transdermal system or the interacting drug should be chosen, depending on the importance of the drug to the patient. If the interacting drug cannot be avoided, monitor patients for CNS adverse reactions. 7.2 Anticholinergic Drugs Concomitant use of scopolamine with other drugs having anticholinergic properties may increase the risk of CNS adverse reactions [see Drug Interactions (7.1) ], intestinal obstruction and/or urinary retention. Consider more frequent monitoring during treatment with scopolamine transdermal system in patients receiving anticholinergic drugs [see Warnings and Precautions (5.2 , 5.4) ] . 7.3 Oral Drugs Absorbed in the Stomach Scopolamine transdermal system, as an anticholinergic, may delay gastric and upper gastrointestinal motility and, therefore, the rate of absorption of other orally administered drugs. Monitor patients for modified therapeutic effect of concomitant orally administered drugs with a narrow therapeutic index. 7.4 Interaction with Gastric Secretion Test Scopolamine will interfere with the gastric secretion test. Discontinue scopolamine transdermal system 10 days prior to testing.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Scopolamine, a belladonna alkaloid, is an anticholinergic. Scopolamine acts: i) as a competitive inhibitor at postganglionic muscarinic receptor sites of the parasympathetic nervous system, and ii) on smooth muscles that respond to acetylcholine but lack cholinergic innervation. It has been suggested that scopolamine acts in the central nervous system (CNS) by blocking cholinergic transmission from the vestibular nuclei to higher centers in the CNS and from the reticular formation to the vomiting center. Scopolamine can inhibit the secretion of saliva and sweat, decrease gastrointestinal secretions and motility, cause drowsiness, dilate the pupils, increase heart rate, and depress motor function. 12.3 Pharmacokinetics The system is formulated to deliver approximately 1 mg of scopolamine to the systemic circulation over 3 days. Absorption Following application to the skin behind the ear, circulating plasma concentrations are detected within 4 hours with peak concentrations being obtained, on average, within 24 hours. The average plasma concentration produced is 87 pg/mL (0.28 nM) for free scopolamine and 354 pg/mL for total scopolamine (free + conjugates). Following removal of the used transdermal system, there is some degree of continued systemic absorption of scopolamine bound in the skin layers. Distribution The distribution of scopolamine is not well characterized. It crosses the placenta and the blood brain barrier and may be reversibly bound to plasma proteins. Elimination Metabolism and Excretion Scopolamine is metabolized and conjugated with less than 5% of the total dose appearing unchanged in the urine. The enzymes responsible for metabolizing scopolamine are unknown. The exact elimination pattern of scopolamine has not been determined. Following transdermal system removal, plasma concentrations of scopolamine decline in a log linear fashion with an observed half-life of 9.5 hours. Less than 10% of the total dose is excreted in the urine as the parent drug and metabolites over 108 hours. Drug Interaction Studies An in vitro study using human hepatocytes examined the induction of CYP1A2 and CYP3A4 by scopolamine. Scopolamine did not induce CYP1A2 and CYP3A4 isoenzymes at the concentrations up to 10 nM. In an in vitro study using human liver microsomes which evaluated the inhibition of CYP1A2, 2C8, 2C9, 2C19, 2D6 and 3A4, scopolamine did not inhibit these cytochrome P450 isoenzymes at the concentrations up to 1 micromolar. No in vivo drug-drug interaction studies have been conducted.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Administration Instructions Counsel patients on how to apply and remove the transdermal system [see Dosage and Administration (2.1) ] : Only wear one transdermal system at any time. Do not cut the transdermal system. Apply the transdermal system to the skin in the postauricular (hairless area behind one ear) area. After the transdermal system is applied on the dry skin behind the ear, wash hands thoroughly with soap and water and dry hands. If the transdermal system becomes displaced, discard the transdermal system, and apply a new transdermal system on the hairless area behind the other ear. Once the transdermal system has been affixed, avoid touching or applying pressure to the transdermal system, since pressure exerted on it may cause scopolamine to ooze out at the edge. Upon removal, fold the used transdermal system in half with the sticky side together, and discard in household trash in a manner that prevents accidental contact or ingestion by children, pets, or others. Wash the hands and application site with soap and water after transdermal system removal. Patients with Open-Angle Glaucoma Advise patients with open-angle glaucoma to remove the scopolamine transdermal system immediately and contact their healthcare provider if they experience symptoms of acute angle closure glaucoma, including pain and reddening of the eyes, accompanied by dilated pupils, blurred vision and/or seeing halos around lights [see Warnings and Precautions (5.1) ] . Neuropsychiatric Adverse Reactions Advise patients that psychiatric adverse reactions may occur, especially in patients with a past psychiatric history or in those receiving other drugs also associated with psychiatric effects, and to report to their healthcare provider any new or worsening psychiatric symptoms. Advise patients to discontinue scopolamine transdermal system and contact a healthcare provider immediately if they experience a seizure. Advise patients, especially elderly patients, that cognitive impairment may occur during treatment with scopolamine transdermal system, especially in those receiving other drugs also associated with CNS effects, and to report to their healthcare provider if they develop signs or symptoms of cognitive impairment such as hallucinations, confusion, or dizziness. Inform patients not to operate motor vehicles or other dangerous machinery or participate in underwater sports until they are reasonably certain that scopolamine transdermal system does not affect them adversely [see Warnings and Precautions (5.2) ]. Decreased Gastrointestinal Motility and Urinary Retention Instruct patients to remove the transdermal system if they develop symptoms of intestinal obstruction (abdominal pain, nausea, or vomiting) or any difficulties in urinating [see Warnings and Precautions (5.4) ] . Drug Withdrawal/Post-Removal Symptoms Inform patients that if they remove the scopolamine transdermal system before treatment is complete, withdrawal symptoms may occur and to seek immediate medical care if they develop severe symptoms after removing scopolamine transdermal system [see Warnings and Precautions (5.5) ] . Blurred Vision Inform patients that temporary dilation of the pupils and blurred vision may occur if scopolamine transdermal system comes in contact with the eyes. Instruct patients to wash their hands thoroughly with soap and water immediately after handling the transdermal system, do not touch the system while wearing it, and wash hands and the application site with soap and water after transdermal system removal [see Dosage and Administration (2.1) , Warnings and Precautions (5.6) ] .

INSTRUCTIONS FOR USE Scopolamine (skoe-POL-a-meen) Transdermal System Read this Instructions for Use before you start using scopolamine transdermal system and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment. Information about scopolamine transdermal system: Scopolamine transdermal system is a tan-colored, circle shaped transdermal system (patch) with "Scopolamine 1 mg/3 days" printed on it. Wear only one scopolamine transdermal system at any time. Do not cut scopolamine transdermal system. To help prevent nausea and vomiting from motion sickness: Apply one scopolamine transdermal system to your skin on a hairless area behind one ear at least 4 hours before the activity to prevent nausea and vomiting. If the treatment is needed for longer than 3 days, remove scopolamine transdermal system from the hairless area behind your ear. Get a new scopolamine transdermal system and place it on the hairless area behind your other ear. To help prevent nausea and vomiting after surgery: Follow your doctor's instructions about when to apply scopolamine transdermal system before your scheduled surgery. Scopolamine transdermal system should be left in place for 24 hours after surgery. After 24 hours, scopolamine transdermal system should be removed and thrown away. How to use scopolamine transdermal system: Inside the scopolamine transdermal system package, you will find one scopolamine transdermal system. An imprinted, tan backing membrane with a metallic (silver) sticky surface is adhered to a clear, disposable release liner (See Figure 1 ). 1. Select a hairless area of skin behind one of your ears. Avoid areas on your skin that may have cuts, pain, or tenderness. Wipe the area of your skin with a clean, dry tissue. 2. Cut along the dashed line on the scopolamine transdermal system package to open (See Figure 2 ). 3. Remove the clear plastic backing from the tan-colored round scopolamine transdermal system (See Figure 3 ). 4. Do not touch the metallic adhesive (sticky) surface on scopolamine transdermal system with your hands (See Figure 4 ). 5. Apply the metallic adhesive surface of scopolamine transdermal system firmly to the dry area of skin behind your ear. The imprinted, tan-colored side of the transdermal system should be facing up and showing (See Figure 5 ). After placement of scopolamine transdermal system, avoid touching or applying pressure to the transdermal system while it is being worn because applying pressure may cause scopolamine to ooze out at the edge. Wash your hands with soap and water right away after applying scopolamine transdermal system, so that any medicine from scopolamine transdermal system that gets on your hands will not get into your eyes. How to remove scopolamine transdermal system: After removing scopolamine transdermal system, be sure to wash your hands and the area behind your ear thoroughly with soap and water. Please note that the used scopolamine transdermal system will still contain some of the active ingredient after use. To avoid accidental contact or ingestion by children, pets, or others, fold the used scopolamine transdermal system in half with the sticky side together. Throw away (dispose of) scopolamine transdermal system in the household trash out of the reach of children, pets, or others. How should I store scopolamine transdermal system? Store scopolamine transdermal system at room temperature between 68°F and 77°F (20°C and 25°C) until you are ready to use it. Store scopolamine transdermal system in an upright position. Do not bend or roll scopolamine transdermal system. Keep scopolamine transdermal system and all medicines out of reach of children. The Patient Information and Instructions for Use have been approved by the U.S. Food and Drug Administration. Revised: 4/2024 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5

14 CLINICAL STUDIES 14.1 Prevention of Motion Sickness In 195 adult subjects of different racial origins who participated in clinical efficacy studies at sea or in a controlled motion environment, there was a 75% reduction in the incidence of motion-induced nausea and vomiting. Scopolamine transdermal system was applied from 4 to 16 hours prior to the onset of motion in these studies. 14.2 Prevention of Post-Operative Nausea and Vomiting A clinical efficacy study evaluated 168 adult female patients undergoing gynecological surgery with anesthesia and opiate analgesia. Patients received scopolamine transdermal system or placebo applied approximately 11 hours before anesthesia/opiate analgesia. No retching/vomiting during the 24-hour post-operative period was reported in 79% of those treated with scopolamine transdermal system compared to 72% of those receiving placebo. When the need for additional antiemetic medication was assessed during the same period, there was no need for medication in 89% of patients treated with scopolamine transdermal system as compared to 72% of placebo-treated patients.

8.5 Geriatric Use Clinical trials of scopolamine transdermal system did not include sufficient number of subjects aged 65 years and older to determine if they respond differently from younger subjects. In other clinical experience, elderly patients had an increased risk of neurologic and psychiatric adverse reactions, such as hallucinations, confusion, dizziness, and drug withdrawal syndrome [see Warnings and Precautions (5.2 , 5.5) ]. Consider more frequent monitoring for CNS adverse reactions during treatment with scopolamine transdermal system in elderly patients [see Warnings and Precautions (5.2) ] .

8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. Pediatric patients are particularly susceptible to the adverse reactions of scopolamine including mydriasis, hallucinations, amblyopia, and drug withdrawal syndrome. Neurologic and psychiatric adverse reactions, such as hallucinations, amblyopia, and mydriasis have also been reported.

8.1 Pregnancy Risk Summary Eclamptic seizures have been reported in pregnant women with severe preeclampsia soon after injection of intravenous or intramuscular scopolamine. Avoid use of scopolamine transdermal system in patients with severe preeclampsia [see Warnings and Precautions (5.3) and Data ] . Available data from observational studies and postmarketing reports with scopolamine use in pregnant women have not identified a drug associated risk of major birth defects, miscarriage, or adverse fetal outcomes. In animal studies, there was no evidence of adverse developmental effects with intravenous administration of scopolamine hydrobromide revealed in rats. Embryotoxicity was observed in rabbits at intravenous doses producing plasma levels approximately 100 times the levels achieved in humans using a transdermal system. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data In published case reports, two pregnant patients with severe preeclampsia were administered intravenous and intramuscular scopolamine, respectively, and developed eclamptic seizures soon after scopolamine administration [see Warnings and Precautions (5.3) ] . Animal Data In animal reproduction studies, when pregnant rats and rabbits received scopolamine hydrobromide by daily intravenous injection, no adverse effects were observed in rats. An embryotoxic effect was observed in rabbits at doses producing plasma levels approximately 100 times the levels achieved in humans using a transdermal system. Scopolamine administered parenterally to rats and rabbits at doses higher than the dose delivered by scopolamine transdermal system did not affect uterine contractions or increase the duration of labor.

8 USE IN SPECIFIC POPULATIONS Geriatric Patients : Consider more frequent monitoring during treatment due to increased risk of CNS adverse reactions. ( 5.2 , 8.5 ) Renal or Hepatic Impairment : Consider more frequent monitoring during treatment due to increased risk of CNS adverse reactions.
