Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in more detail in other sections of the labeling: Cardiovascular Effects with Concomitant Use of Drugs Metabolized by Catechol-O-Methyltransferase (COMT) [see Warnings and Precautions ( 5.1 )] Falling Asleep During Activities of Daily Living and Somnolence [see Warnings and Precautions ( 5.2 )] Hypotension/Syncope [see Warnings and Precautions ( 5.3 )] Dyskinesia [see Warnings and Precautions ( 5.4 )] Hallucinations and Psychosis [see Warnings and Precautions ( 5.5 )] Impulse Control/Compulsive Disorders [see Warnings and Precautions ( 5.6 )] Withdrawal-Emergent Hyperpyrexia and Confusion [see Warnings and Precautions ( 5.7 )] Most common adverse reactions (≥4% and > placebo): dyskinesia, constipation,...
Interactions
7 DRUG INTERACTIONS 7.1 Non-Selective Monoamine Oxidase (MAO) Inhibitors Both ONGENTYS and non-selective MAO inhibitors (e.g., phenelzine, isocarboxazid, and tranylcypromine) inhibit catecholamine metabolism, leading to increased levels of catecholamines. Concomitant use may increase the risk of possible arrhythmias, increased heart rate, and excessive changes in blood pressure. Concomitant use of ONGENTYS with non-selective MAO inhibitors is contraindicated [see Contraindications ( 4 )] . Selective MAO-B inhibitors can be used concomitantly with ONGENTYS.
Warnings
5 WARNINGS AND PRECAUTIONS Cardiovascular Effects with Concomitant Use of Drugs Metabolized by Catechol-O-Methyltransferase (COMT): May cause arrhythmias, increased heart rate, and excessive changes in blood pressure. Monitor patients when treated concomitantly with products metabolized by COMT. ( 4 , 5.1 ) Falling Asleep During Activities of Daily Living: Advise patients prior to treatment. ( 5.2 ) Hypotension/Syncope: If occurs, consider discontinuing ONGENTYS or adjusting dosage of other medications that can lower blood pressure. ( 5.3 ) Dyskinesia: May cause or exacerbate dyskinesia; consider levodopa or dopaminergic medication dose reduction. ( 5.4 ) Hallucinations and Psychosis: Consider stopping ONGENTYS if occurs. 4 CONTRAINDICATIONS ONGENTYS is contraindicated in patients with: Concomitant use of non-selective monoamine oxidase (MAO) inhibitors [ see Drug Interactions ( 7.1 ) ] . Pheochromocytoma, paraganglioma, or other catecholamine secreting neoplasms. Concomitant use of non-selective monoamine oxidase (MAO) inhibitors.
Pregnancy
8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with use of ONGENTYS in pregnant women. In animal studies, oral administration of opicapone during pregnancy resulted in adverse effects on embryofetal development (increased incidence of fetal abnormalities) at clinically relevant plasma exposures in one of two species tested. In addition, opicapone is always given concomitantly with levodopa/carbidopa, which is known to cause developmental toxicity in rabbits ( s ee Data ). The background risk of major birth defects and miscarriage in the U.S.
