Remodulin adverse reactions

Adverse reactions with SC Remodulin1

In controlled 12-week pivotal trials in PAH, patients receiving SC Remodulin experienced the following adverse reactions at least 3% more frequently than patients receiving placebo.1*

In clinical studies of SC Remodulin infusion, the most common adverse events reported were1:

  • Infusion site pain
  • Infusion site reaction (redness, swelling, and rash)

These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin.1

7% discontinuation due to infusion site pain1

Incidence of infusion site reactions and site pain1
Site Reaction (%) Site Pain (%)
Remodulin Placebo Remodulin Placebo
Severe 38 1 39 2
Requiring narcotics NA§ NA§ 32 1
Leading to discontinuation 3 0 7 0

NA=not available.

*Reported adverse reactions (at least 3% more frequent on drug than on placebo) are included except those too general to be informative and those not plausibly attributable to the use of the drug because they were associated with the condition being treated or are very common in the treated population.1

Infusion site reaction was defined as any local adverse event other than pain or bleeding/bruising at the infusion site and included symptoms such as erythema, induration, or rash.1

Based on prescriptions for narcotics, not actual use.

§Medications used to treat infusion site pain were not distinguished from those used to treat site reactions.

Remodulin additional common adverse events

Other common adverse events (≥3% more than placebo) seen with SC Remodulin or placebo, respectively, were1:

  • Headache (27% vs 23%)
  • Diarrhea (25% vs 16%)
  • Nausea (22% vs 18%)
  • Rash (14% vs 11%)
  • Jaw pain (13% vs 5%)
  • Vasodilatation (11% vs 5%)
  • Edema (9% vs 3%)

Adverse reactions with IV Remodulin

The IV infusion of Remodulin with an external infusion pump has been associated with a risk of1:

  • Bloodstream infections
  • Arm swelling
  • Paresthesias
  • Hematoma
  • Pain

IV=intravenous; PAH=pulmonary arterial hypertension; SC=subcutaneous.

Important Safety Information

Warnings and Precautions

  • Chronic intravenous (IV) infusions of Remodulin delivered using an external infusion pump with an indwelling central venous catheter are associated with the risk of blood stream infections (BSIs) and sepsis, which may be fatal. Therefore, continuous subcutaneous (SC) infusion is the preferred mode of administration.
  • Avoid abrupt withdrawal or sudden large reductions in dosage of Remodulin, which may result in worsening of PAH symptoms.
  • Titrate slowly in patients with hepatic or renal insufficiency, because such patients will likely be exposed to greater systemic concentrations relative to patients with normal hepatic or renal function.
  • Remodulin is a pulmonary and systemic vasodilator. In patients with low systemic arterial pressure, treatment with Remodulin may produce symptomatic hypotension.
  • Remodulin inhibits platelet aggregation and increases the risk of bleeding.

Adverse Reactions

  • In clinical studies of SC Remodulin infusion, the most common adverse events reported were infusion site pain and infusion site reaction (redness, swelling, and rash). These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin. The IV infusion of Remodulin with an external infusion pump has been associated with a risk of blood stream infections, arm swelling, paresthesias, hematoma, and pain. Other common adverse events (≥3% more than placebo) seen with either SC or IV Remodulin were headache (27% vs. 23%), diarrhea (25% vs. 16%), nausea (22% vs. 18%), rash (14% vs. 11%), jaw pain (13% vs. 5%), vasodilatation (11% vs. 5%), edema (9% vs. 3%), and hypotension (4% vs. 2%).

Drug Interactions

  • Remodulin dosage adjustment may be necessary if inhibitors or inducers of CYP2C8 are added or withdrawn.

Specific Populations

  • In patients with mild or moderate hepatic insufficiency, decrease the initial dose of Remodulin to 0.625 ng/kg/min of ideal body weight, and monitor closely. Remodulin has not been studied in patients with severe hepatic insufficiency.
  • Safety and effectiveness of Remodulin in pediatric patients have not been established.
  • It is unknown if geriatric patients respond differently than younger patients. Caution should be used when selecting a dose for geriatric patients.
  • There are no adequate and well-controlled studies with Remodulin in pregnant women. It is not known whether treprostinil is excreted in human milk or if it affects the breastfed infant or milk production.

Indication

Remodulin is a prostacyclin vasodilator indicated for the treatment of pulmonary arterial hypertension (PAH; WHO Group 1) to diminish symptoms associated with exercise. Studies establishing effectiveness included patients with NYHA Functional Class II-IV symptoms and etiologies of idiopathic or heritable PAH (58%), PAH associated with congenital systemic-to-pulmonary shunts (23%), or PAH associated with connective tissue diseases (19%).

In patients with PAH requiring transition from epoprostenol, Remodulin is indicated to diminish the rate of clinical deterioration. Consider the risks and benefits of each drug prior to transition.
