What is Humulin R Vial?
It contains regular human insulin called Insulin made from recombinant DNA technology. Humulin R is a type of fast-acting insulin with a 6-8 hours duration of action.
Humulin R is an aqueous, colorless, and sterile solution that is available in 100IU/mL. Eli Lilly and Company Indiana Pvt Ltd. is the manufacturer of Humulin N and Zuellig Pharmaceuticals is the distributor.
What is it used for?
Humulin R helps patients with both Type 1 and Type 2 Diabetes mellitus to maintain their blood glucose levels.
How does it work?
It maintains sugar levels from spiking by lessening the production in the liver and increasing sugar reuptake in the muscle and fat cells. Humulin can also lower the progression of complications in diabetic patients like Retinopathy, Nephropathy, Neuropathy, and diabetic foot ulcer.
How to take it
Humulin R vial must contain a clear and colorless solution for injection. Discard immediately if the contents appear colored, cloudy, thick, and with visible solid particles. Draw equal dose of air inside the vial and get the Insulin into the syringe. Remove the bubbles present in the syringe. Clean the administration site before injecting the desired dose subcutaneously. The patient can administer it in the abdomen, thighs, and upper arms. Change the injection site after every dose with a distance of approximately 1.5cm (0.5 inches) to avoid damaging the tissue. Do not rub the area of injection.
Humulin R must be prescribed by the doctor. The dose may change according to the need of the patient concerning diet and lifestyle.
Blurred vision, anxiety, confusion, drowsiness, tachycardia, weakness, nausea, and difficulty speaking and concentrating are some signs of Hypoglycemia that can be seen in patients taking Humulin.
Warnings, Precautions, and Contraindications
Hypoglycemia and hyperglycemia can cause coma, loss of consciousness, or even death in the patients. Hence, driving or operating machinery should be avoided as blood glucose levels must be monitored for all patients taking Humulin. Insulin dose may increase if the patient is taking Humulin with oral contraceptives, thiazides, sympathomimetics, corticosteroids, danazol, or thyroid replacement therapy. The dosage may also decrease in the combination of salicylates, sulfa antibiotics, monoamine oxidase inhibitors, beta-blockers, ACEIs, and alcohol. Taking thiazolidinedione with this drug may result in swelling of the lower extremities and heart failure. Do not use after the expiry date.
Depression in the skin (lipoatrophy), skin lumps (localized subcutaneous amyloidosis), or enlargement of tissue (lipohypertrophy) are the rare results of injecting Insulin subcutaneously but a change in injection technique may solve the problem. Notify the healthcare provider if the patient has a rash all over the body, shortness of breath, diabetic acidosis, reduction in blood pressure, and coma after administration of Humulin.
Humulin R vials should be stored in the refrigerator with a temperature ranging from 2-8°C. In-use cartridges should remain in a temperature not exceeding 25°C for up to 28 days. Do not freeze, store in the bathroom, or with direct sunlight as it may affect the quality of the product.
