Insulin human regular (Injection route)
IN-su-lin HUE-man REG-yoo-lar
Uses of This Medicine:
Insulin human regular is a short-acting type of insulin. Insulin is used by people with diabetes to help keep blood sugar levels under control. If you have diabetes, your body cannot make enough or does not use insulin properly. So, you must take additional insulin to regulate your blood sugar and keep your body healthy. This is very important as too much sugar in your blood can be harmful to your health.
This medicine is available only with your doctor's prescription.
