Safe Use and Disposal Reminder

Always dispose of single-use needles immediately after use in a proper sharps container. Never throw used needles in the trash, recycling bin, or flush them down the toilet. Using an approved sharps container helps prevent injury, contamination, and the spread of infection. Be sure to follow local regulations for sharps disposal.

Pen Device Compatibility

Owen Mumford Unifine Pentips Pen Needles are designed for universal fit with most “Type A” pen injector devices. They are compatible with leading insulin pen brands and models from Novo Nordisk, Lilly, Berlin Chemie, Sanofi Aventis, Owen Mumford, and other widely used pen systems, offering flexibility and easy integration into your diabetes care routine.

How to Choose the Right Pen Needle Size

Choosing the correct pen needle size depends on several factors, including your body type, injection site, and overall comfort. Shorter needles are often effective for subcutaneous insulin delivery and may reduce discomfort.

Needle Gauge: The gauge refers to the needle's thickness. Higher gauge numbers mean thinner needles. For example, a 33G (0.20 mm) needle is thinner than a 31G (0.25 mm) needle, which can offer a more comfortable injection experience.
Needle Length: Common options include 5/32 in (4 mm), 3/16 in (5 mm), 15/64 in (6 mm), and 5/16 in (8 mm). Shorter needles, such as 5/32 in (4 mm) and 3/16 in (5 mm), are often preferred for ease of use and are suitable for most users when used with proper technique.

Consult your healthcare provider to determine the most appropriate gauge and length based on your individual needs and injection technique.

Safe Needle Use and Disposal

Always use pen needles as instructed by your healthcare provider. Never reuse needles or syringes. After each use, dispose of needles properly in a designated sharps container to prevent injury or infection.

Pen Needle Storage and Handling

Store pen needles in a cool, dry place away from direct sunlight and moisture. Always keep them sealed in their original packaging until ready for use. For specific storage guidelines and expiration details, refer to the manufacturer’s instructions or product information sheet included with your purchase.
