About Basaglar
Overview
Basaglar contains insulin glargine, a long-acting insulin, and comes in a prefilled pen for injection under the skin. It is used to improve blood sugar control in adults and children with type 1 diabetes and adults with type 2 diabetes. It lowers blood sugar by helping muscle and fat cells take up glucose and reducing the amount of glucose the liver produces. It is not recommended for treating diabetic ketoacidosis.
What it treats
- Type 1 diabetes in adults and children, to improve blood sugar control. - Type 2 diabetes in adults, to improve blood sugar control. Not recommended for treating diabetic ketoacidosis.
Safety information
Side effects
Common side effects of Basaglar include low blood sugar, allergic reactions, injection-site reactions, changes in fatty tissue at injection sites, itching, rash, swelling and weight gain. Serious side effects include severe low blood sugar, severe allergic reactions (including anaphylaxis) and low blood potassium. These can be life-threatening and require urgent medical attention. Basaglar used with diabetes medicines called thiazolidinediones (TZDs) can also cause fluid retention and heart failure; contact your doctor promptly if these occur. Check the insulin label before every injection, as accidental mix-ups between insulin products can cause low blood sugar.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not use Basaglar during an episode of low blood sugar (hypoglycemia), or if you are allergic to insulin glargine or any other ingredient in Basaglar. Low blood sugar can be life-threatening. More frequent blood glucose checks may be needed if your insulin treatment, other glucose-lowering medicines, meal pattern or physical activity changes. Extra monitoring is also needed if you have kidney or liver impairment, or do not recognise the warning signs of low blood sugar. Changes to your insulin treatment, injection site or injection method should be made under close medical supervision. Never share a Basaglar pen with anyone, even if the needle is changed. Check the insulin label before each injection to avoid mix-ups. Basaglar can cause severe, life-threatening allergic reactions, including anaphylaxis. If a severe allergic reaction occurs, stop using Basaglar and seek immediate medical help. It can also cause dangerously low potassium levels; people at risk may need potassium monitoring. Using Basaglar with thiazolidinediones (TZDs) can cause fluid retention and heart failure. Your prescriber should monitor for signs of heart failure and review treatment if it occurs.
Interactions
Other medicines and alcohol can affect how Basaglar controls blood sugar. More frequent blood sugar checks may be needed, and your prescriber may need to adjust your treatment. Medicines that may increase the risk of low blood sugar include other diabetes medicines, ACE inhibitors, angiotensin II receptor blockers, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs such as octreotide, and sulfonamide antibiotics. Medicines that may reduce Basaglar’s blood sugar-lowering effect include atypical antipsychotics such as olanzapine and clozapine, corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens, protease inhibitors, somatropin, sympathomimetic medicines such as albuterol, epinephrine and terbutaline, and thyroid hormones. Alcohol, beta-blockers, clonidine and lithium salts may either increase or decrease Basaglar’s blood sugar-lowering effect. Pentamidine may cause low blood sugar, sometimes followed by high blood sugar. Beta-blockers, clonidine, guanethidine and reserpine may make the warning signs of low blood sugar less noticeable. Raise these interactions with your doctor, as more frequent blood sugar checks may be needed even when symptoms are less apparent.
Using Basaglar
Dosing
Dosing is set by your prescriber. Each health care professional may prescribe medication differently according to a patient's medical history and condition, so follow the directions on your prescription label and speak to your doctor or pharmacist before changing anything.
Storage
Store in the original carton to protect it from light. Check the pack for whether it must be refrigerated before first use and how long it may be kept at room temperature afterwards. Keep all medicines out of the sight and reach of children.
