Clinically significant adverse reactions that appear in other sections of the labeling include: Angioedema [see Warnings and Precautions ( 5.2 )] Hypotension [see Warnings and Precautions ( 5.3 )] Impaired Renal Function [see Warnings and Precautions ( 5.4 )] Hyperkalemia [see Warnings and Precautions ( 5.5 )] Adverse reactions occurring greater than or equal to 5% are hypotension, hyperkalemia, cough, dizziness, and renal failure.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Heart Failure In PARADIGM-HF, patients were required to complete sequential enalapril and sacubitril and valsartan tablets run-in periods of (median) 15 and 29 days, respectively, prior to entering the randomized double-blind period comparing sacubitril and valsartan tablets and enalapril.
During the enalapril run-in period, 1,102 patients (10.5%) were permanently discontinued from the study, 5.6% because of an adverse event, most commonly renal dysfunction (1.7%), hyperkalemia (1.7%) and hypotension (1.4%). During the sacubitril and valsartan tablets run-in period, an additional 10.4% of patients permanently discontinued treatment, 5.9% because of an adverse event, most commonly renal dysfunction (1.8%), hypotension (1.7%) and hyperkalemia (1.3%).
Because of this run-in design, the adverse reaction rates described below are lower than expected in practice. In the double-blind period, safety was evaluated in 4,203 patients treated with sacubitril and valsartan tablets and 4,229 treated with enalapril. In PARADIGM-HF, patients randomized to sacubitril and valsartan tablets received treatment for up to 4.3 years, with a median duration of exposure of 24 months; 3,271 patients were treated for more than one year.
Discontinuation of therapy because of an adverse event during the double-blind period occurred in 450 (10.7%) of sacubitril and valsartan tablets-treated patients and 516 (12.2%) of patients receiving enalapril. Adverse reactions occurring at an incidence of greater than or equal to 5% in patients who were treated with sacubitril and valsartan tablets in the double-blind period of PARADIGM-HF are shown in Table 3. In PARADIGM-HF, the incidence of angioedema was 0.1% in both the enalapril and sacubitril and valsartan tablets run-in periods.
In the double-blind period, the incidence of angioedema was higher in patients treated with sacubitril and valsartan tablets than enalapril (0.5% and 0.2%, respectively). The incidence of angioedema in Black patients was 2.4% with sacubitril and valsartan tablets and 0.5% with enalapril [see Warnings and Precautions ( 5.2 )] . Orthostasis was reported in 2.1% of patients treated with sacubitril and valsartan tablets compared to 1.1% of patients treated with enalapril during the double-blind period of PARADIGM-HF.
Falls were reported in 1.9% of patients treated with sacubitril and valsartan tablets compared to 1.3% of patients treated with enalapril. Table 3: Adverse Reactions Reported in greater than or equal to 5% of Patients Treated with Sacubitril and Valsartan Tablets in the Double-Blind Period of PARADIGM-HF Sacubitril and Valsartan Tablets (n = 4,203) % Enalapril (n = 4,229) % Hypotension 18 12 Hyperkalemia 12 14 Cough 9 13 Dizziness 6 5 Renal failure/acute renal failure 5 5 Pediatric Heart Failure The adverse reactions observed in pediatric patients 1 year to less than 18 years old who received treatment with sacubitril and valsartan tablets were consistent with those observed in adult patients.
L aboratory Abnormalities Hemoglobin and Hematocrit Decreases in hemoglobin/hematocrit of greater than 20% were observed in approximately 5% of both sacubitril and valsartan tablets and enalapril treated patients in the double-blind period in PARADIGM-HF. Serum Creatinine During the double-blind period in PARADIGM-HF, approximately 16% of both sacubitril and valsartan tablets -and enalapril-treated patients had increases in serum creatinine of greater than 50%.
Serum Potassium During the double-blind period of PARADIGM-HF, approximately 16% of both sacubitril and valsartan tablets -and enalapril-treated patients had potassium concentrations greater than 5.5 mEq/L.
