Remodulin Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Remodulin (treprostinil sodium) is a vasodilator that works by dilating (widening) the arteries used to treat pulmonary arterial hypertension (PAH). Remodulin improves the ability to exercise and prevents the condition from getting worse. Common side effects of Remodulin include nausea, vomiting, diarrhea, headache, dizziness, jaw pain, flushing (warmth, redness, or tingly feeling), skin rash, or injection site reactions (redness, swelling, pain, or a hard lump).
Remodulin is indicated for subcutaneous (SC) or intravenous (IV) use only as a continuous infusion and is administered in a clinical setting. The infusion rate is initiated at 1.25 ng/kg/min. If this initial dose cannot be tolerated because of side effects, the infusion rate may be reduced to 0.625 ng/kg/min. Remodulin may interact with blood pressure medications, bosentan, blood thinners, diuretics (water pills), or medications to treat congestive heart failure. Tell your doctor all medications and supplements you use. During pregnancy, Remodulin should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Remodulin FDA Prescribing Information: Side Effects
The following adverse reactions are discussed elsewhere in labeling: Infections associated with intravenous administration [see WARNINGS AND PRECAUTIONS].
Clinical 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.
Adverse Events with Subcutaneously Administered Remodulin
Patients receiving Remodulin as a subcutaneous infusion reported a wide range of adverse events, many potentially related to the underlying disease (dyspnea, fatigue, chest pain, right ventricular heart failure, and pallor). During clinical trials with subcutaneous infusion of Remodulin, infusion site pain and reaction were the most common adverse events among those treated with Remodulin. 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. Infusion site reactions were sometimes severe and could lead to discontinuation of treatment.

subcutaneous infusion site adverse events
|Leading to discontinuation||0||3||0||7|
|* 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
Other adverse events included diarrhea, jaw pain, edema, vasodilatation and nausea, and these are generally considered to be related to the pharmacologic effects of Remodulin, whether administered subcutaneously or intravenously.
Adverse Reactions during Chronic Dosing
Table 4 lists adverse reactions defined by a rate of at least 3% more frequent in patients treated with subcutaneous Remodulin than with placebo in controlled trials in PAH.

|Infusion Site Reaction||83||27|
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.
While hypotension occurred in both groups, the event was experienced twice as frequently in the Remodulin group as compared to the placebo group (4% in Remodulin treatment group verses 2% in placebo-controlled group). As a potent vasodilator, hypotension is possible with the administration of Remodulin.
The safety of Remodulin was also studied in a long-term, open-label extension study in which 860 patients were dosed for a mean duration of 1.6 years, with a maximum exposure of 4.6 years. Twenty-nine (29%) percent achieved a dose of at least 40 ng/kg/min (max: 290 ng/kg/min). The safety profile during this chronic dosing study was similar to that observed in the 12-week placebo controlled study except for the following suspected adverse drug reactions (occurring in at least 3% of patients): anorexia, vomiting, infusion site infection, asthenia, and abdominal pain.
Adverse Events Attributable to the Drug Delivery System
In controlled studies of Remodulin administered subcutaneously, there were no reports of infection related to the drug delivery system. There were 187 infusion system complications reported in 28% of patients (23% Remodulin, 33% placebo); 173 (93%) were pump related and 14 (7%) related to the infusion set. Eight of these patients (4 Remodulin, 4 Placebo) reported non-serious adverse events resulting from infusion system complications. Adverse events resulting from problems with the delivery systems were typically related to either symptoms of excess Remodulin (e.g., nausea) or return of PAH symptoms (e.g., dyspnea). These events were generally resolved by correcting the delivery system pump or infusion set problem such as replacing the syringe or battery, reprogramming the pump, or straightening a crimped infusion line. Adverse events resulting from problems with the delivery system did not lead to clinical instability or rapid deterioration. In addition to these adverse events due to the drug delivery system during subcutaneous administration, the following adverse events may be attributable to the IV mode of infusion including arm swelling, paresthesias, hematoma and pain [see WARNINGS AND PRECAUTIONS].
In addition to adverse reactions reported from clinical trials, the following events have been identified during post-approval use of Remodulin. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The following events have been chosen for inclusion because of a combination of their seriousness, frequency of reporting, and potential connection to Remodulin. These events are thrombophlebitis associated with peripheral intravenous infusion, thrombocytopenia bone pain, pruritus and dizziness. In addition, generalized rashes, sometimes macular or papular in nature, and cellulitis have been infrequently reported.
