SIDE EFFECTS

Adult Patients: Fenoldopam causes a dose-related fall in blood pressure and increase in heart rate (see PRECAUTIONS, Tachycardia, and Hypotension). In controlled clinical studies of severe hypertension in patients with end-organ damage, 3% (4/137) of patients withdrew because of excessive falls in blood pressure. Increased heart rate could, in theory, lead to ischemic cardiac events or worsened heart failure, although these events have not been observed. The most common events reported as associated with fenoldopam use are headache, cutaneous dilation (flushing), nausea, and hypotension, each reported in more than 5% of patients.

Adverse reactions in controlled trials in hypertensive adult patients

Adverse events occurring more than once in any dosing group (once if potentially important or plausibly drug-related) in the fixed-dose constant-infusion studies are presented in the following Table by infusion-rate group. There was no clear dose relationship, except possibly for headache, nausea, flushing.

Adverse effects in overall database

The adverse event incidences listed below are based on observations of over 1,000 fenoldopam treated adult patients and not listed in Table 4 above.

Events reported with a frequency between 0.5-5% in patients treated with IV fenoldopam

Cardiovascular: extrasystoles, palpitations, bradycardia, heart failure, ischemic heart disease, myocardial infarction, angina pectoris

Metabolic: elevated BUN, elevated serum glucose, elevated transaminase, elevated LDH

General Body: non-specific chest pain, pyrexia

Hematologic/Lymphatic: leukocytosis, bleeding

Respiratory: Dyspnea, upper respiratory disorder

Genitourinary: Oliguria

Musculoskeletal: limb cramp

Pediatric Patients: In pediatric patients, the most common adverse events reported during short term administration in controlled trials (30 minutes) were hypotension and tachycardia. However, because of the short exposure, there is limited experience with defining adverse events in children. The long-term effects of fenoldopam on growth and development have not been studied.

DRUG INTERACTIONS

General: Although there have been no formal interaction studies, intravenous fenoldopam has been administered safely with drugs such as digitalis and sublingual nitroglycerin. There is limited experience with concomitant antihypertensive agents such as alpha-blockers, calcium channel-blockers, ACE inhibitors, and diuretics (both thiazide-like and loop).
