Introduction
Actrapid SC Injection 100 IU/10 ml is a form of insulin used to manage blood glucose levels in individuals with diabetes. It is designed to act quickly after administration to control blood sugar spikes that occur after meals. It is commonly used in conjunction with other forms of insulin or oral diabetes medications.
Uses
This fast-acting insulin is used for:
- Managing blood glucose levels in patients with type 1 or type 2 diabetes mellitus.
- Controlling postprandial (after-meal) hyperglycemia.
- Providing rapid insulin action to meet the body's immediate insulin needs, particularly in meal-related blood glucose control.

Mechanism of Action
Actrapid SC Injection 100 IU/10 ml works by facilitating the uptake of glucose into cells, particularly in muscle and fat tissues. It promotes the storage of glucose as glycogen in the liver and reduces glucose production. By mimicking natural insulin, it helps lower blood glucose levels quickly following injection.
How Long Does It Take to Work?
Fast-acting insulin typically begins to work within 15 minutes of injection, with peak effects occurring between 30 minutes and 1.5 hours. Its duration of action usually lasts between 3 to 5 hours, providing quick control of postprandial glucose levels.
Absorption
Actrapid SC Injection 100 IU/10 ml is absorbed rapidly from the subcutaneous tissue into the bloodstream. Peak plasma concentrations are typically reached within 1 hour following injection, leading to its quick onset of action.
Route of Elimination
Insulin is primarily metabolized in the liver and kidneys. It is broken down into inactive metabolites that are then excreted in the urine. The majority of insulin is cleared from the body through the liver, with renal clearance playing a secondary role.
Dosage
The dosage of Actrapid SC Injection 100 IU/10 ml is individualized based on the patient's needs, blood glucose levels, and other factors. Common starting doses range from 4 to 10 units administered subcutaneously before each meal. Dosage adjustments are made based on blood glucose monitoring and patient response.
Administration
Actrapid SC Injection 100 IU/10 ml is administered subcutaneously, typically in the abdomen, thigh, or upper arm. It should be injected approximately 15 minutes before a meal. Rotate injection sites to reduce the risk of lipodystrophy and ensure consistent absorption.
Side Effects
Common side effects include:
- Hypoglycemia (low blood sugar), which can cause symptoms like dizziness, shaking, sweating, and confusion.
- Injection site reactions, such as redness, swelling, or itching.
- Weight gain, particularly with long-term use.
Serious side effects may include:
- Severe hypoglycemia leading to loss of consciousness or seizures.
- Allergic reactions, including rash, swelling, or difficulty breathing.
Toxicity
Overdose of insulin can lead to severe hypoglycemia, characterized by symptoms like confusion, seizures, loss of consciousness, or even coma. Treatment involves immediate administration of glucose or glucagon and close monitoring of blood glucose levels.
Precautions
Precautions include:
- Regular monitoring of blood glucose levels to avoid hypoglycemia.
- Adjusting dosage based on changes in diet, exercise, or illness.
- Using with caution in patients with renal or hepatic impairment, as insulin metabolism can be affected.
Interaction
Drug interactions include:
- Certain medications, such as corticosteroids or diuretics, can affect blood glucose levels and may require dosage adjustments.
- Alcohol can enhance the hypoglycemic effects of insulin, increasing the risk of low blood sugar.
Disease Interaction
Patients with the following conditions should use Actrapid SC Injection 100 IU/10 ml with caution:
- Renal or hepatic impairment, as these conditions can affect insulin metabolism and clearance.
- Endocrine disorders such as thyroid disease, which can influence insulin sensitivity and glucose metabolism.
Drug Interaction
Potential drug interactions include:
- Medications that affect insulin absorption or action, such as other antidiabetic agents or drugs that alter gastrointestinal motility.
- Drugs that impact blood glucose levels, such as beta-blockers or certain antibiotics.
Consult with a healthcare provider to manage potential drug interactions effectively.
Food Interactions
Food intake can affect insulin action and blood glucose levels. It is important to coordinate insulin administration with meal times to avoid hypoglycemia or hyperglycemia. Be mindful of carbohydrate content and meal timing to optimize insulin effectiveness.
Pregnancy Use
The use of Actrapid SC Injection 100 IU/10 ml during pregnancy is generally considered safe and may be required to manage diabetes effectively. However, insulin requirements may change during pregnancy. Regular monitoring and adjustment of dosage are essential, and a healthcare provider should oversee its use during this period.
Lactation Use
Actrapid SC Injection 100 IU/10 ml is not known to be excreted into breast milk in significant amounts. It is generally considered safe to use while breastfeeding, but blood glucose levels should be monitored closely. Consult a healthcare provider for personalized advice on managing diabetes while lactating.
Acute Overdose
Acute overdose can lead to severe hypoglycemia. Symptoms may include confusion, seizures, loss of consciousness, and in extreme cases, coma. Immediate treatment with oral glucose or intravenous glucose or glucagon is necessary. Seek emergency medical care if an overdose is suspected.
Contraindication
Actrapid SC Injection 100 IU/10 ml is contraindicated in:
- Patients with hypersensitivity to insulin or any component of the formulation.
- Patients with severe hypoglycemia or insulin-dependent hypoglycemia without appropriate medical supervision.
Use Direction
Administer Actrapid SC Injection 100 IU/10 ml subcutaneously as directed by a healthcare provider. Typically, it is injected 15 minutes before a meal to manage postprandial blood glucose levels. Follow the prescribed dosage and timing instructions carefully, and monitor blood glucose levels regularly.
Storage Conditions
Store Actrapid SC Injection 100 IU/10 ml in a cool, dry place away from direct sunlight. It should be refrigerated until use, but can be kept at room temperature for up to 28 days once opened. Avoid freezing. Keep out of reach of children.
Volume of Distribution
The volume of distribution for Insulin Human is relatively small, indicating that it primarily remains in the vascular and interstitial compartments. Insulin distributes throughout the extracellular fluid and has minimal tissue penetration beyond these compartments.
Half Life
The half-life of Actrapid SC Injection 100 IU/10 ml is approximately 4-6 minutes. This rapid clearance is due to its fast action and short duration of effect, necessitating frequent dosing to manage blood glucose levels effectively.
Clearance
Insulin is primarily cleared through hepatic metabolism and renal excretion. The clearance rate is influenced by various factors, including renal function, liver function, and the presence of other medications.
