Insulin Summary
Neutral insulin is a man‑made form of the body’s natural sugar‑controlling hormone, used mainly in diabetes to bring down high blood sugar. Insulin acts like a key that lets sugar into cells for energy and tells the liver to stop making extra sugar. Its most common side effect is low sugar (hypoglycemia), which can cause sweating, shakiness, or dizziness; sometimes there may be mild skin reactions where it’s injected. Alcohol can make low sugar worse. It should be kept in the fridge (not frozen), protected from heat and light, and once opened it can stay at room temperature for about a month.
