NovoRapid Penfill is a fast-acting insulin preparation that contains insulin aspart, a man-made form of human insulin. It is used to control high blood sugar levels in people with diabetes mellitus, including both type 1 and type 2 diabetes. The Penfill cartridge is designed for use with insulin delivery pens, making it easier and more convenient for patients to administer their insulin doses, especially around mealtime.

Mechanism of Action:
Insulin aspart works similarly to the natural insulin produced by the pancreas.

• After injection, it starts acting quickly to help lower blood glucose levels by allowing sugar to move from the bloodstream into cells, where it can be used for energy.

• It begins working within 10 to 20 minutes, peaks around 1 to 3 hours, and its effects can last for up to 5 hours.

• This rapid action helps manage the rise in blood sugar that occurs after eating.

  Uses:
  NovoRapid Penfill is prescribed for:

  • Type 1 diabetes, where the body produces little or no insulin

  • Type 2 diabetes, when diet, exercise, and oral medicines are not enough

  • It is suitable for both adults and children and can be used during pregnancy under medical guidance

  • It helps prevent complications like kidney damage, vision problems, nerve issues, and cardiovascular disease by maintaining better blood sugar control

  Adverse Effects:
  While NovoRapid is effective and generally well tolerated, some possible side effects include:

  • Low blood sugar (hypoglycemia), which may cause sweating, shakiness, dizziness, confusion, or fainting if untreated

  • Weight gain over time, especially when blood sugar levels are tightly controlled

  • Injection site reactions, such as redness, swelling, or itching

  • Allergic reactions, though rare, can include rash or serious symptoms like difficulty breathing

  • Long-term use may rarely cause lipodystrophy, or changes in fat tissue under the skin at the injection site, if the injection spot is not rotated
