Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.

Local: Injection site reaction (5% to 6%)

Concerns related to adverse effects:

• Constipation: Constipation, including cases with serious complications resulting in hospitalization and surgery, has been reported. Constipation has generally occurred after the first dose; however, a later onset has also been observed. Concurrent use of medications that decrease GI motility may increase the risk for more severe constipation and the potential for constipation-related complications.

• Hypersensitivity: Hypersensitivity reactions, including rash, angioedema, and anaphylaxis, have been reported. Most reactions are mild to moderate and occur within hours after administration, but some may be delayed for >1 week. If a hypersensitivity reaction occurs, discontinue treatment and institute appropriate therapy.

• Hypertension: New-onset and worsening of preexisting hypertension, including cases requiring pharmacological treatment or hospitalization, have been reported. Onset most frequently reported after the initial dose and within 7 days of administration but may occur at any time. Monitor patients and consider discontinuing treatment in patients whom an alternative etiology is not established.

Disease related concerns:

• Cardiovascular disease: May cause hypertension; use with caution in patients with hypertension or risk factors for hypertension.

Dosage form specific issues:

• Latex: The packaging (needle shield of auto-injector and needle cap of prefilled syringe) may contain latex.
