Single-use pen needles

Use

• When administering injectable medicines, choosing the correct needle length is important. Shorter needles (4, 5 or 6 mm) are generally recommended for patients, as a shorter needle length is associated with less perceived pain.⁶
• CONTOUR®COMFORT pen needles are intended for single use and must be removed immediately after each injection. Reusing needles can lead to complications such as lipohypertrophy and infections.⁷
