Regular Human Insulin
About Regular Human Insulin
Regular Human Insulin is an injectable medicine used to control high blood sugar in adults and children with diabetes mellitus. By helping your body manage glucose levels, it plays a vital role in preventing long-term complications associated with diabetes. This medicine is prescribed for both type 1 and type 2 diabetes.
To get the best results, you must inject Regular Human Insulin consistently and exactly as prescribed by your doctor. It is typically injected 30 minutes before a meal to align with your body's sugar uptake. Alongside your injections, maintaining a structured meal plan and engaging in regular physical activity are essential steps to successfully manage your blood sugar levels.
Like many diabetes medications, Regular Human Insulin can cause side effects, with low blood sugar being the most common. You may also experience mild redness, swelling, or itching around the area where you inject. If you experience severe symptoms, such as extreme confusion, sweating, a rapid heartbeat, or signs of a serious allergic reaction, seek emergency medical care immediately.
Before you begin using this medicine, talk to your doctor about your complete medical history. Do not take this if you are currently experiencing an episode of low blood sugar or if you have ever had an allergic reaction to this medicine or any of its ingredients. It is also important to tell your healthcare provider if you have kidney or liver issues or if you have heart failure.
Using Regular Human Insulin alongside other medicines, alcohol, or tobacco can affect how well it works and may increase your risk of severe low blood sugar. For example, drinking alcohol can unpredictably lower your blood sugar and mask the warning signs of hypoglycemia. Always consult your doctor if you are pregnant, planning a pregnancy, breastfeeding, or if you are caring for an elderly patient, as insulin requirements often change during these stages of life.
Uses of Regular Human Insulin
Medicinal Benefits
Regular Human Insulin helps control blood sugar levels by replacing the insulin your body needs to move glucose from the bloodstream into the cells. It is particularly effective in controlling blood sugar levels around mealtimes.
- Controls Post-Meal Blood Sugar: Helps prevent sharp increases in blood sugar after meals by acting soon after injection.
- Maintains Blood Sugar Control: Supports healthy blood glucose levels when used regularly as part of a diabetes management plan.
- Reduces the Risk of Diabetes Complications: Good blood sugar control helps lower the risk of complications affecting the eyes, kidneys, nerves, heart, and blood vessels.
- Supports Daily Well-Being: Stable blood sugar levels may help improve energy levels and reduce symptoms such as excessive thirst, frequent urination, and fatigue.
- Provides Reliable Mealtime Insulin Coverage: Helps mimic the body's natural insulin response to meals when taken as prescribed.
Directions for Use
Always follow your doctor's exact instructions regarding your dose and timing. Below are the standard steps for preparing and injecting Regular Human Insulin:
- Wash your hands thoroughly with soap and water before handling your injection equipment.
- Check the liquid inside the vial or cartridge; it must be completely clear and colourless. Do not use it if it looks cloudy, thickened, or has particles floating in it.
- Clean the injection site on your skin (usually the stomach, thigh, upper arm, or buttocks) with an alcohol swab and let it dry.
- Gently pinch a fold of skin, insert the needle at a 90-degree angle (or as directed by your doctor), and press the plunger to inject the dose.
- Keep the needle under the skin for a few seconds to ensure the full dose is delivered, then pull it straight out.
- Rotate your injection sites with every dose to keep your skin healthy and prevent lumps from forming.

Patients Concern
Disease/Condition Glossary
Type 1 diabetes mellitus: In type 1 diabetes mellitus, our body does not make insulin (the hormone which helps to decrease sugar levels in the blood) to control blood sugar levels.
Type 2 diabetes mellitus: In type 2 diabetes mellitus, either the body stops producing enough insulin, or there is resistance to the action of insulin. As a result, insulin is produced in sufficient amounts but is unable to act on the tissues of the organs.
FAQs
Regular Human Insulin is used in the treatment of type 1 and type 2 diabetes mellitus.
Regular Human Insulin works by increasing the glucose uptake by fats and muscles, suppresses the production of glucose in the liver, and also the formation of glycogen from glucose. These effects help in reducing the glucose levels in the blood.
In hypoglycemia, blood sugar levels decrease significantly. It causes symptoms such as dizziness, headache, sweating, hunger, loss of consciousness, rapid breathing, or seizure (fits). In such cases, seek medical attention immediately.
If you experience low blood sugar, eat glucose tablets, chocolate, or another high sugar snack such as sweet or biscuit. Use a blood glucose monitor to test your blood sugar levels after 15 minutes if possible. Eat a snack or have proper meals if the blood glucose returns to normal.

Because this is a short-acting insulin designed to match your body's response to food, it is generally best to inject it 30 minutes before your meal. Injecting it after you eat may increase the risk of a blood sugar spike followed by low blood sugar later. Talk to your doctor if you have trouble with meal timing.
You can inject this medicine into the abdomen, thighs, upper arms, or buttocks. The abdomen absorbs insulin the fastest, making it the preferred site before meals. Always rotate your injection sites to keep your skin healthy, and talk to your doctor or pharmacist about proper injection techniques.
Injecting in the exact same spot too often can cause fat deposits under the skin to clump or shrink. This can make the skin feel bumpy and, more importantly, can make your body absorb insulin unevenly, leading to unpredictable blood sugar levels. Talk to your pharmacist for tips on site rotation.
Once opened, you can keep the vial, cartridge, or pen at room temperature (below 30°C) for up to 28 days. Keep it away from direct heat and light. Do not freeze it, and do not put it back in the refrigerator once it has been kept at room temperature. Talk to your pharmacist if you have questions about storage.
