warnings and cautions
5 WARNINGS AND PRECAUTIONS Acute exacerbation of coronary artery disease upon cessation of therapy: Do not abruptly discontinue. ( 5.1 ) Bradycardia, hypotension, worsening heart failure/fluid retention may occur. Reduce the dose as needed. ( 5.2 , 5.3 , 5.4 ) Non-allergic bronchospasm (e.g., chronic bronchitis and emphysema): Avoid β-blockers. ( 4 ) However, if deemed necessary, use with caution and at lowest effective dose. ( 5.5 ) Diabetes: Monitor glucose as β-blockers may mask symptoms of hypoglycemia or worsen hyperglycemia. ( 5.6 ) 5.1 Cessation of Therapy Patients with coronary artery disease, who are being treated with carvedilol, should be advised against abrupt discontinuation of therapy. Severe exacerbation of angina and the occurrence of myocardial infarction and ventricular arrhythmias have been reported in patients with angina following the abrupt discontinuation of therapy with β-blockers. The last 2 complications may occur with or without preceding exacerbation of the angina pectoris. As with other β-blockers, when discontinuation of carvedilol is planned, the patients should be carefully observed and advised to limit physical activity to a minimum. carvedilol should be discontinued over 1 to 2 weeks whenever possible. If the angina worsens or acute coronary insufficiency develops, it is recommended that carvedilol be promptly reinstituted, at least temporarily. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue therapy with carvedilol abruptly even in patients treated only for hypertension or heart failure. 5.2 Bradycardia In clinical trials, carvedilol caused bradycardia in about 2% of hypertensive subjects, 9% of subjects with heart failure, and 6.5% of subjects with myocardial infarction and left ventricular dysfunction. If pulse rate drops below 55 beats per minute, the dosage should be reduced. 5.3 Hypotension In clinical trials of primarily mild‑to‑moderate heart failure, hypotension and postural hypotension occurred in 9.7% and syncope in 3.4% of subjects receiving carvedilol compared with 3.6% and 2.5% of placebo subjects, respectively. The risk for these events was highest during the first 30 days of dosing, corresponding to the up‑titration period and was a cause for discontinuation of therapy in 0.7% of subjects receiving carvedilol, compared with 0.4% of placebo subjects.

adverse reactions
6 ADVERSE REACTIONS Most common adverse events ( 6.1 ): Heart failure and left ventricular dysfunction following myocardial infarction (≤10%): Dizziness, fatigue, hypotension, diarrhea, hyperglycemia, asthenia, bradycardia, weight increase. Hypertension (≥5%): Dizziness. To report SUSPECTED ADVERSE REACTIONS, contact Advagen Pharma Ltd., at 866-488-0312 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Studies 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Carvedilol has been evaluated for safety in subjects with heart failure (mild, moderate, and severe), in subjects with left ventricular dysfunction following myocardial infarction and in hypertensive subjects The observed adverse event profile was consistent with the pharmacology of the drug and the health status of the subjects in the clinical trials. Adverse events reported for each of these patient populations are provided below. Excluded are adverse events considered too general to be informative, and those not reasonably associated with the use of the drug because they were associated with the condition being treated or are very common in the treated population. Rates of adverse events were generally similar across demographic subsets (men and women, elderly and non-elderly, blacks and non-blacks). Heart Failure Carvedilol tablets has been evaluated for safety in heart failure in more than 4,500 subjects worldwide of whom more than 2,100 participated in placebo-controlled clinical trials. Approximately 60% of the total treated population in placebo-controlled clinical trials received carvedilol for at least 6 months and 30% received carvedilol for at least 12 months. In the COMET trial, 1,511 subjects with mild-to-moderate heart failure were treated with carvedilol for up to 5.9 years (mean: 4.8 years). Both in U.S. clinical trials in mild-to-moderate heart failure that compared carvedilol tablets in daily doses up to 100 mg (n = 765) with placebo (n = 437), and in a multinational clinical trial in severe heart failure (COPERNICUS) that compared carvedilol tablets in daily doses up to 50 mg (n = 1,156) with placebo (n = 1,133), discontinuation rates for advers...
