Insulin glargine is not a drug of choice for the treatment of diabetic ketoacidosis. In such cases, intravenous insulin administration is recommended.
Due to limited experience with the drug Insulin Glargine it was not possible to evaluate its efficacy and safety in the treatment of patients with impaired liver function or patients with moderate to severe or severe renal insufficiency.
In patients with impaired renal function the need for insulin may decrease due to a slowdown in its elimination. In elderly patients, progressive deterioration of kidney function can lead to a persistent decrease in insulin requirements.
In patients with severe hepatic insufficiency the need for insulin can be lowered due to a decrease in the ability to gluconeogenesis and slowing down the biotransformation of insulin.
In case of ineffective control of blood glucose level, as well as in the presence of a tendency to develop hypo- or hyperglycemia, before proceeding with correction of the dosing regimen, it is necessary to check the accuracy of the prescribed treatment regimen, adherence to the directions for the injection site and the correctness of the technique Subcutaneous injection taking into account all the factors affecting it.
Hypoglycaemia
The time of development of hypoglycemia depends on the profile of the insulin used and can, therefore, change with a change in the treatment regimen. Due to the increased time of insulin administration to the body of long-term action when using the drug Insulin Glargine, we should expect a lower probability of developing nocturnal hypoglycemia, whereas in the early morning hours this probability of hypoglycemia is higher. When hypoglycemia occurs in patients receiving Insulin Glargine, should consider the possibility of slowing the output from the state of hypoglycemia in connection with the prolonged action of insulin glargine.
Patients who have episodes of hypoglycemia may have a particular clinical significance, such as patients with severe stenosis of the coronary arteries or cerebral vessels (risk of developing cardiac and cerebral complications of hypoglycemia), as well as patients with proliferative retinopathy, especially if they do not receive photocoagulation treatment (risk transient loss of vision following a hypoglycemia), special care should be taken and intensified monitoring of blood glucose levels. Patients should be warned about conditions in which symptoms-precursors of hypoglycemia may decrease. In patients of certain risk groups, the symptoms of hypoglycemia may change, become less pronounced or absent. These include:
- patients who have significantly improved blood glucose regulation;
- patients who develop hypoglycemia gradually;
- patients of advanced age;
- patients transferred from insulin of animal origin to human insulin;
- patients with neuropathy;
- patients with a long history of diabetes mellitus;
- patients suffering from mental disorders;
- patients receiving concomitant treatment with other medications (see "Interaction with other drugs").
Such situations can lead to the development of severe hypoglycemia (with possible loss of consciousness) before the patient realizes that he is developing hypoglycemia.
In the event that normal or decreased glycosylated hemoglobin levels are noted, the possibility of developing recurrent unrecognized episodes of hypoglycemia (especially at night) should be considered.
Patient compliance with the dosing regimen and diet, proper insulin administration and knowledge of hypoglycaemic precursors contribute to a significant reduction in the risk of developing hypoglycemia.
Factors that increase the tendency to hypoglycemia, in the presence of which a particularly careful observation is required and correction of the insulin dose may be necessary:
- change the place of insulin administration;
- increased sensitivity to insulin (for example, when stress factors are eliminated);
- unusual, increased or prolonged physical activity;
- intercurrent diseases, accompanied by vomiting, diarrhea;
- violation of diet and diet;
- missed food intake;
- alcohol consumption;
- Some uncompensated endocrine disorders (eg, hypothyroidism, adenohypophysis deficiency or adrenal cortex);
- concomitant medication with some other medicines.
Intercurrent diseases
When intercurrent diseases require more intensive monitoring of blood glucose levels. In many cases, the analysis of the presence of ketone bodies in the urine is shown, and often a correction of the insulin dosage regimen is required. The need for insulin often increases. Patients with type 1 diabetes should continue to regularly consume at least a small amount of carbohydrates, even if they are able to consume only small amounts of food or can not eat at all or if they have vomiting, etc., and they should never completely stop the introduction of insulin.
Instruction for use and circulation
Pre-filled syringe handles OptiSet
Before use, inspect the cartridge inside the syringe pen. It should only be used if the solution is clear, colorless, contains no visible solid particles and resembles water in a consistency.
Empty Optic syringes should not be reused and must be destroyed.
To prevent infection, a pre-filled syringe pen should only be used by one patient and not transferred to another person.
Handling of syringe-handle OptiSet
Before using the OptiSet pen, carefully read the usage information.
Important information on the use of the OptiSet syringe pen
- Always use a new needle every time you use it. Use only needles that are suitable for the Optix syringe.
- Always give a safety test before each injection.
- If a new OptiSet pen is used, the readiness check should be performed using 8 units preset by the manufacturer.
- The dose selector can only be rotated in one direction.
- Never turn the dose selector (dose change) after pressing the injection pushbutton.
- This insulin syringe pen is intended only for patients. You can not betray her to another person.
- If another person injects the patient, he needs to take extra care to avoid accidentally injuring the needle and infecting the infectious disease.
- Never use a damaged OptiSet pen, or if you are not sure of its serviceability.
- Always have a spare OptiSet pen in case your OptiSet syringe is damaged or lost.
Insulin testing
After removing the cap from the syringe pen, the labeling on the insulin tank must be checked to make sure it contains the proper insulin. You should also check the appearance of insulin: the insulin solution should be clear, colorless, free of visible solids and have a consistency similar to water. You can not use the OptiSet syringe if the insulin solution is cloudy, has a color or foreign particles.
Attaching the needle
After removing the cap, you should carefully and tightly connect the needle to the syringe pen.
Checking the availability of the syringe pen for use
Before each injection, it is necessary to check the readiness of the syringe pen for use.
For a new and unused syringe pen, the dose indicator should stand on the figure 8, as was previously set by the manufacturer.
If a syringe pen is used, the dispenser should be rotated until the dose indicator stops at 2. The dispenser will rotate in only one direction.
Pull out the fully-actuated button to dial the dose. Never rotate the dose selector after the start button is pulled out.
The outer and inner needle caps must be removed. Save the outer cap to remove the used needle.
Holding the syringe handle with the needle pointing upwards, gently tap with your finger on the insulin reservoir so that the air bubbles rise up towards the needle.
Then press the start button all the way.
If a drop of insulin is released from the tip of the needle, the syringe-pen and the needle function correctly.
If a drop of insulin is not displayed at the tip of the needle, repeat the readiness check of the syringe pen until the insulin appears on the tip of the needle.
Selecting an insulin dose
A dose of 2 units up to 40 units can be set in increments of 2 units. If a dose exceeding 40 units is required, it must be administered in two or more injections.
Make sure you have enough insulin for the right dose.
The scale of the residual insulin on a transparent container for insulin shows how much, approximately, of the insulin remains in the syringe-handle OptiSet. This scale can not be used to take a dose of insulin.
If the black piston is at the beginning of a colored strip, then there are approximately 40 units of insulin.
If the black piston is at the end of a colored strip, then there are about 20 units of insulin.
The dose selector should be rotated until the arrow-dose indicator indicates the desired dose.
Insulin Dose Fence
The injection button must be pulled to the limit to fill the insulin pen.
Check to see if the correct dose has been dialed. Note that the button is shifted according to the amount of insulin left in the insulin container.
The start button allows you to check which dose is dialed. During the test, the start button must be kept under tension.The last visible wide line on the start button shows the amount of insulin taken. When the start button is held, only the upper part of this wide line is visible.
Introduction of insulin
Specially trained personnel should explain the technique of injecting to the patient.
The needle must be administered subcutaneously.
Press the injection button to the limit. The click will stop when the injection pushbutton is depressed. Then press the injection button for 10 seconds before pulling the needle out of the skin. This will ensure the introduction of the entire dose of insulin.
Removing the needle
After each injection, the needle should be removed from the syringe-pen and discarded. This will prevent infection, as well as leakage of insulin, air intake and possible blockage of the needle. Needles should not be reused.
Then you need to put the cap back on the syringe pen.
Cartridges
Cartridges should be used together with the Optipen Pro1 syringe pen, and in accordance with the recommendations given by the device manufacturer.
Instructions for using the OptiPen Pro1 syringe for installing the cartridge, connecting the needle and performing insulin injection should be carried out exactly. Inspect the cartridge before use.It should only be used if the solution is clear, colorless, and contains no visible solid particles. Before installing the cartridge in the syringe pen, the cartridge should be at room temperature for 1-2 hours. Before carrying out the injection, remove air bubbles from the cartridge. It is necessary to strictly follow the instructions. Empty cartridges are not used again. If the OptiPen Pro1 syringe pen is damaged, you can not use it.
If the syringe pen is faulty, if necessary, insulin can be injected into the patient by typing the solution from the cartridge into a plastic syringe (suitable for insulin at a concentration of 100 IU / ml).
To prevent infection with a reusable pen, only one person should use it.
OptiKlik cartridge system
The Optiklik cartridge system is a glass cartridge containing 3 ml of the glargine insulin solution, which is placed in a transparent plastic container with an attached piston mechanism.
The Optiklik cartridge system should be used together with the Optiklik syringe handle in accordance with the instruction manual attached to it.
All the recommendations contained in the instruction for installing the cartridge system in the OpticClip needle pen, connecting the needle and performing the injection must be exactly followed.
If the OpticClip syringe is damaged, replace it with a new one.
Before installing the cartridge system into the OptiKlik syringe, it should be at room temperature for 1-2 hours. Inspect the cartridge system before installation. It should only be used if the solution is clear, colorless, and contains no visible solid particles. Before carrying out the injection, remove air bubbles from the cartridge system (see the instructions for using the syringe pen). Empty cartridge systems are not reused.
If the syringe pen is defective, then, if necessary, insulin can be administered to the patient by typing the solution from the cartridge into a plastic syringe (suitable for insulin at a concentration of 100 IU / ml).
To prevent infection with a reusable pen, only one person should use it.
