Available without a prescription, NPH insulin is a medication used for treating diabetes. It is an intermediate-acting insulin that is used to control blood sugar throughout the day. NPH insulin comes in injectable form and is injected just under the skin, usually once or twice daily. While most people tolerate this form of insulin well, potential side effects include changes in blood sugar levels and injection site skin reactions.
- Low blood sugar levels (hypoglycemia)
- A skin reaction at the injection site
- Thickening or pitting of the skin at the injection site.
