Description:

Insulatard 100IU/ml Flexpen is used to improve blood sugar control in adults and children with type 1 and type 2 diabetes mellitus. It is an intermediate-acting type of insulin that helps to lower blood sugar levels and reduce the chances of developing serious complications of diabetes.

Insulatard 100IU/ml Flexpen is often prescribed along with short-acting insulin or other oral diabetes medicines. Your doctor or nurse will teach you the correct way of injecting it under the skin. Don’t stop taking it unless your doctor tells you to. It is only part of a treatment program that should also include a healthy diet, regular exercise, and weight reduction as advised by your doctor.

Check your blood sugar levels regularly, keep track of your results and share them with your doctor. This is very important to work out the correct dose of the medicine for you.

The most common side effect of this medicine is low blood sugar levels (hypoglycemia). To prevent this, it's important to always inject the correct dose of medicine only, have regular meals, and monitor your blood sugar levels regularly. Drinking excessive alcohol can also lead to a fall in your blood sugar levels. Other side effects include reactions at the injection site like redness or swelling. Repeated puncturing of the same site of the skin may lead to lipodystrophy (skin thickening or pits at the injection site). Some people may gain weight or develop edema (swelling over the whole body due to fluid retention) while taking insulin.

Do not use this medicine when you have low blood glucose levels (hypoglycemia). Tell your doctor if you have ever had kidney, liver or heart problems before starting treatment. Pregnant or breastfeeding women should also consult their doctor as the dose may need to be changed.

FAQs:

How does biphasic isophane insulin work?

Insulin isophane is a recombinant human insulin analogue (genetically modified insulin that is grown in a laboratory and similar to human insulin). It is an intermediate acting insulin preparation. Insulin isophane acts by replacing the normal production of insulin and by helping transfer sugar from the blood into other body tissues where it is utilized to generate energy. It also stops the liver from producing more sugar. Intermediate acting insulin preparations start acting within an hour or 2 of injection, and reach a period of peak activity that lasts up to 7 hours, following which the action trails off; overall duration of action ranges from 18 to 24 hours.
