Signs and Symptoms

Hypoxemia, hypotension, and respiratory arrest leading to death have been reported in clinical practice following overdosage of FLOLAN.

Excessive doses of FLOLAN were associated with flushing, headache, hypotension, tachycardia, nausea, vomiting, and diarrhea during clinical trials.

One patient with PAH/SSD accidentally received 50 mL of an unspecified concentration of FLOLAN. The patient vomited and became unconscious with an initially unrecordable blood pressure. FLOLAN was discontinued and the patient regained consciousness within seconds.

Single intravenous doses of FLOLAN at 10 and 50 mg/kg (2,703 and 27,027 times the recommended acute phase human dose based on body surface area) were lethal to mice and rats, respectively. Symptoms of acute toxicity were hypoactivity, ataxia, loss of righting reflex, deep slow breathing, and hypothermia.


Discontinue or reduce dose of FLOLAN.


FLOLAN is contraindicated in patients with heart failure caused by reduced left ventricular ejection fraction [see Clinical Studies].

FLOLAN is contraindicated in patients with a hypersensitivity to the drug or any of its ingredients.

This monograph has been modified to include the generic and brand name in many instances.
