Intermediate-acting insulins are typically cloudy in appearance. Specifically, Insulin NPH is known for its cloudy look.
Insulin NPH, sold under brand names such as Humulin-N and Novolin ge NPH, is an intermediate-acting insulin used to manage blood sugar levels, usually taken between meals and at bedtime. Its cloudy appearance is due to the presence of protamine and zinc, which are added to slow down its absorption and prolong its action in the body.
Understanding the appearance of different insulin types is important for proper administration and storage. While intermediate-acting insulins like NPH are cloudy, other types of insulin are clear.
