Description
Insulin human regular is a short-acting type of insulin. Insulin is one of many hormones that help the body turn the food we eat into energy. This is done by using the glucose (sugar) in the blood as quick energy. Also, insulin helps us store energy that we can use later. When you have diabetes mellitus, your body cannot make enough insulin or does not use insulin properly. This causes you to have too much sugar in your blood. Like other types of insulin, insulin human regular is used to keep your blood sugar level close to normal.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:

Proper Use
A nurse or other trained health professional may give you this medicine. You may also be taught how to give your medicine at home. This medicine is given as a shot under your skin (eg, stomach, thigh, or upper arm) or into a vein.
Always double-check both the concentration (strength) of your insulin and your dose. Concentration and dose are not the same. The dose is how many units of insulin you will use. The concentration tells how many units of insulin are in each milliliter (mL), such as 100 units/mL (U-100), but this does not mean you will use 100 units at a time.
Each package of insulin human regular contains a patient information sheet. Read this sheet carefully before beginning your treatment and each time you refill for any new information, and make sure you understand:
- How to prepare the medicine.
