Offering the simplicity of a button-free autoinjector, purpose designed with patient-friendly features
Introducing Metoject® PEN
Metoject® PEN is a once a week pre-filled methotrexate auto-injector, indicated for the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, psoriasis and Crohn’s disease1.
Evidence supports subcutaneous methotrexate as more efficacious and tolerable than orally administered methotrexate2, making Metoject® PEN a suitable first choice for eligible patients.
Key Benefits of Metoject® PEN Compared to Oral Administration
Greater Bioavailability
Subcutaneous administration of methotrexate offers more reliable, dose-proportional exposure which does not plateau3.
Improved GI Tolerability in Patients
Adverse effects related to the frequency and intensity of gastrointestinal discomfort were lesser in patients treated with subcutaneous methotrexate4.
