Basaglar® Cartridge for Long-Acting Insulin Glargine U-100

What Basaglar® Is and How It Works

Basaglar is insulin glargine 100 units/mL, a long-acting basal insulin for adults with type 1 or type 2 diabetes, and for certain children when prescribed. It provides steady 24-hour background insulin with no pronounced peak. Dosing is once daily at the same time each day. Many people search for Basaglar Cartridge order online to access Canadian pricing, including those buying without insurance.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba, and all prescriptions are reviewed by licensed pharmacists before dispensing.

Basaglar Cartridges are 3 mL units designed for use in compatible reusable insulin pens. The clear solution releases slowly after subcutaneous injection into the abdomen, thigh, or upper arm. Do not mix or dilute insulin glargine with other insulins. Basaglar helps lower fasting and between-meal glucose and can reduce A1C when titrated to target.

We also partner with licensed, vetted international pharmacies to source authentic brands, offering broad selection at affordable prices.

Dosage and Usage

• Your prescriber sets your starting dose based on prior therapy, weight, and goals. Typical use is once daily at the same time.
• Type 1 diabetes usually needs mealtime insulin as well. Basal dose is only part of the total daily insulin.
• Do not mix Basaglar with other insulins in the same syringe or pen. Do not use intravenously or in an insulin pump.
• Use only in a compatible reusable pen. Insert the cartridge per the pen’s instructions, then attach a new needle for each injection.
• Prime the pen (for example, 2 units) until you see insulin at the needle tip. Dial your dose, insert the needle into skin, and press the button fully. Hold for 10 seconds before removing.
• Rotate injection sites within the same body area to reduce lipodystrophy. Avoid injecting into areas that are tender, bruised, or scarred.
• If you miss a dose, follow your prescriber’s guidance. In general, take it as soon as you remember the same day, then return to your usual schedule. Do not double doses.
• Check glucose regularly during dose changes, illness, or travel. Dose adjustments may be needed under medical supervision.

• Store unopened cartridges in a refrigerator at 2–8°C (36–46°F). Do not freeze. Keep in the original box to protect from light.
• Once in use, keep the pen with cartridge at room temperature (below 30°C/86°F) for up to 28 days. Do not refrigerate a pen in use.
• Do not expose to heat or direct sunlight. Do not use if solution is cloudy, colored, or contains particles.
• For travel, pack spare cartridges in an insulated pouch with cold packs. Do not place cartridges directly against ice. Carry supplies in your hand luggage.
• Remove and safely discard the needle after each injection. Do not share pens, cartridges, or needles.

Benefits and Savings

Basaglar helps smooth fasting and between-meal glucose through a full day. Once-daily dosing supports simple routines. Cartridges let you use a comfortable reusable pen and reduce plastic waste compared with disposables. When titrated appropriately, many patients see meaningful A1C reductions and fewer nocturnal lows compared with some intermediate-acting insulins.

Ordering from Canada can lower your Basaglar Cartridge cost by 60–80% versus typical U.S. prices. If you need Basaglar Cartridge without insurance, Canadian pricing and multi-month supplies can help reduce the monthly spend. You can turn on reorder reminders so you do not run short. Buying a longer supply may lower your per-month cost when bulk promotions are available.

Side Effects and Safety

• Low blood sugar (shakiness, sweating, fast heartbeat, hunger, headache, confusion)
• Injection-site redness, swelling, or itching
• Lipodystrophy or skin thickening at injection sites
• Edema (swelling), weight gain when glucose improves
• Rash or mild allergic reactions
• Rarely, low potassium (hypokalemia)

Serious reactions can include severe hypoglycemia, generalized allergy, and significant hypokalemia. Fluid retention may worsen with thiazolidinediones. Do not use during episodes of hypoglycemia or in diabetic ketoacidosis. Use caution with kidney or liver impairment and in older adults. Hypoglycemia risk increases when Basaglar is combined with rapid-acting insulin or a sulfonylurea; dose adjustments may be needed under medical supervision.

Onset Time

After starting or changing a dose, fasting glucose often improves within several days. The full basal effect builds over 3–7 days as steady state is reached. A1C reflects average glucose over about 8–12 weeks, so most people see A1C changes after two to three months. Weight and dose needs can change as glucose control improves.

Compare With Alternatives

Other long-acting insulin glargine products include Lantus and Semglee (insulin glargine-yfgn). These have similar pharmacology to Basaglar and are dosed once daily in most cases. Differences lie in device, formulary coverage, and price.

If you prefer a disposable pen, consider Basaglar® Kwikpen. It contains the same insulin glargine in a prefilled device and may suit those who do not want to manage separate cartridges.

An intermediate-acting alternative is Novolin® Ge Nph Penfill Cartridge (insulin isophane). It often requires twice-daily dosing and can have more pronounced peaks, which may increase hypoglycemia risk but may fit certain regimens.

Combination Therapy

• With metformin: common in type 2 diabetes to improve basal and hepatic glucose control.
• With GLP-1 receptor agonists: may allow lower insulin doses and weight benefits; monitor for hypoglycemia and adjust insulin as needed.
• With SGLT2 inhibitors: may aid further A1C reduction; ensure adequate hydration and monitor glucose and ketones when appropriate.
• With rapid-acting insulin at meals: standard for type 1 diabetes and for type 2 with post-meal elevations; reduce doses to limit hypoglycemia risk.
• With sulfonylureas: consider lowering sulfonylurea dose to reduce low blood sugar episodes.

Patient Suitability and Cost-Saving Tips

Basaglar may be suitable if a long-acting basal insulin is indicated for your diabetes management. It is not for treating diabetic ketoacidosis, intravenous use, or insulin pumps. People with a history of severe hypoglycemia or hypersensitivity to insulin glargine require careful medical oversight. Pregnancy, breastfeeding, kidney or liver disease, and frequent exercise changes may need dose adjustments by a clinician.

You can manage Basaglar Cartridge purchase online and track your orders in your account. Use refill reminders to avoid gaps. Ordering a multi-month supply may qualify for bulk purchase pricing, lowering your Basaglar insulin cost per month. If you are uninsured, you can still place a Basaglar Cartridge order without insurance and pay the transparent cash price at checkout.
