What is the onset time for intermediate-acting insulin?

The onset time for intermediate-acting insulin is typically between 1 to 2 hours. This means that after the injection, the insulin starts to lower blood sugar levels within this time frame. Intermediate-acting insulin, such as NPH (Neutral Protamine Hagedorn) insulin, is designed to provide a more prolonged effect compared to rapid or short-acting insulins, which have a quicker onset.

This 1 to 2 hour timeframe is important for patients to understand, as it helps them manage their blood glucose levels effectively, especially in relation to meals and physical activity. Knowing when the insulin will start acting can assist in planning meals and snacks accordingly to prevent hypoglycemia or hyperglycemia.

The other options reflect different onset times associated with other types of insulin, with rapid-acting insulins typically having an onset of about 15 minutes and long-acting insulins having a much longer onset time, thereby clarifying the specificity of intermediate-acting insulins' action.
