FAQ
Q1. Are all insulin pen needles compatible?
Ans: Most insulin pen needles are designed with a universal fit, meaning they can be used with the majority of pen injector devices available on the market. These CareLiving needles feature a standard twist-on design compatible with most major brands.
Q2. What size is a 5/16 pen needle in mm?
Ans: A 5/16 inch needle is equivalent to 8 mm in length. This is a common length used for subcutaneous insulin injections to ensure the medication reaches the correct tissue layer.
Q3. What is 31G in an insulin syringe?
Ans: The 31G refers to the gauge or thickness of the needle. A higher gauge number indicates a thinner needle; 31G is an ultra-fine size designed to reduce discomfort during the injection process.
Q4. Are these CareLiving needles authentic imports in India?
Ans: Yes, these are authentic products imported directly from the USA. Rudra Retails sources medical supplies from trusted American distributors to ensure Indian consumers receive genuine international quality healthcare accessories.
Q5. How often should I change the insulin pen needle?
Ans: Medical professionals recommend using a new sterile needle for every injection. Reusing needles can lead to tip dulling, increased pain, and a higher risk of infection or lipodystrophy.
