Tresiba (insulin degludec) FlexTouch insulin pens

Tresiba FlexTouch Pens are prefilled insulin pens that deliver insulin degludec, a long-acting (basal) insulin. They are used as background insulin to help manage blood glucose over a full day. This page summarizes practical basics for access and safe handling, including US shipping from Canada and options for people paying without insurance.

What Tresiba FlexTouch Pens Are and How They Work

Insulin degludec is a basal (background) insulin used to support steady glucose control between meals and overnight. After injection under the skin (subcutaneous), it forms a depot that releases insulin slowly. This helps cover baseline insulin needs and is not designed to correct sudden high glucose or replace mealtime insulin when that is also prescribed. Many people with diabetes use a basal insulin alongside nutrition planning, glucose monitoring, and other medicines.

Prescription details may be verified with the original prescriber when required.

On CanadianInsulin, requests are coordinated through a prescription referral process, and dispensing is completed by appropriately licensed pharmacies. For an overview of long-duration options that work similarly, browse the Long Acting Insulin category hub. For broader context on insulin types and use, the Tresiba Overview Article provides background and common terminology.

Who It’s For

This medicine is prescribed for diabetes mellitus when a clinician determines that basal insulin is appropriate. It may be used in type 1 diabetes (typically along with rapid-acting mealtime insulin) and type 2 diabetes (alone or with other glucose-lowering medicines). People who are comparing treatment pathways can review condition hubs such as Type 1 Diabetes and Type 2 Diabetes to see related therapies and supplies in one place.

It is not used for diabetic ketoacidosis (DKA), which requires urgent medical treatment. A key contraindication is a known serious hypersensitivity (allergic reaction) to insulin degludec or any component of the product. Clinicians may also reassess suitability during episodes of recurrent severe hypoglycemia or when insulin needs change substantially due to illness, steroid treatment, or major changes in intake and activity.

Dosage and Usage

Basal insulin dosing is individualized by the prescriber based on glucose data, other medications, and clinical factors. Many adults are instructed to take insulin degludec once daily, and some regimens allow flexibility in timing when needed, depending on the label and prescriber direction. Dose adjustments are usually made gradually, using home glucose results and the prescriber’s titration plan. When a person is switching from another basal insulin, clinicians often provide a structured transition plan and extra monitoring guidance.

For device technique and day-to-day routine, Tresiba FlexTouch Pens are used by attaching a new pen needle for each injection, priming per the instructions, then injecting into recommended sites such as the abdomen, thigh, or upper arm. Site rotation helps reduce lipohypertrophy (lumpy thickened skin) that can interfere with absorption. The pen should not be shared between people, even if a new needle is used, due to infection risk. For deeper reading, see Tresiba Dosage Guide and FlexTouch Pen Features.

• Same time daily: follow the prescribed schedule.
• Under-skin injection: do not inject into a vein.
• Do not mix: follow product instructions.
• Glucose checks: use the monitoring plan provided.

Strengths and Forms

This product is supplied as a prefilled pen device intended for multiple doses from a single pen. Insulin degludec pens are commonly available in 3 mL pen presentations, and cartons are often provided as a multi-pen pack. Strength availability can vary by market and dispensing pharmacy, so the exact presentation and labeling should be confirmed during the prescription review.

Tresiba FlexTouch Pens may be available in two concentrations, which affects dose dialing and maximum deliverable dose per injection. Patients should confirm that the concentration on the label matches the prescription and education provided. For related options and insulin formats, the Insulin Medications browseable hub can help organize comparisons.

Storage and Travel Basics

Unopened insulin pens are generally stored in the refrigerator until first use, then kept either refrigerated or at room temperature depending on the product instructions. Freezing can damage insulin, so pens should be protected from ice packs that directly contact the device. Heat and direct sunlight can also reduce potency. The in-use time (how long a pen can be kept after first use) is product-specific and should be taken from the package insert or pharmacy labeling.

Licensed Canadian partner pharmacies dispense medications for approved requests.

When traveling, carrying insulin in a temperature-stable pouch and keeping supplies in carry-on baggage can reduce risk from cargo hold temperature extremes. It also helps to bring extra pen needles, glucose testing supplies, and a backup plan for missed doses. Keep the pen cap on when not in use, and inspect insulin for changes in appearance as described in the instructions.

Quick tip: Keep a photo of the carton label and prescription in the travel bag.

Side Effects and Safety

All insulin products can cause hypoglycemia (low blood sugar), which is the most common clinically important risk. Symptoms may include sweating, shaking, confusion, headache, irritability, and fast heartbeat, and severe hypoglycemia can lead to seizures or loss of consciousness. People at higher risk include those with reduced food intake, unplanned strenuous activity, dose errors, or interacting medicines. A prescriber may recommend more frequent checks during illness, after a regimen change, or when switching insulins.

Other effects can include injection-site reactions (redness, pain, swelling), itching, and lipodystrophy (changes in fat tissue at the injection site). Weight gain and edema (fluid retention) can occur with insulin therapy. Serious allergic reactions are uncommon but require urgent medical care if symptoms such as widespread rash, swelling of the face or throat, or trouble breathing occur. For practical context on symptoms and follow-up questions, Tresiba FlexTouch Pens are discussed in the Tresiba Side Effects Guide.

• Most important risk: low blood glucose.
• Local reactions: redness or swelling.
• Skin changes: rotate injection sites.
• Urgent signs: severe allergy symptoms.

Drug Interactions and Cautions

Many drugs can change insulin requirements by increasing or decreasing blood glucose. Examples include corticosteroids, some diuretics, thyroid products, and sympathomimetics, which may raise glucose, and some antidepressants or ACE inhibitors, which may lower glucose in certain people. Alcohol can also increase hypoglycemia risk, especially when intake is inconsistent. Beta-blockers may mask some warning symptoms of low blood sugar, such as tremor or palpitations.

Some people use insulin with other glucose-lowering therapies, and combination plans may require closer monitoring when a medication is started, stopped, or changed. Thiazolidinediones (TZDs) used with insulin have been associated with fluid retention and possible worsening of heart failure in susceptible patients, so clinicians may monitor for swelling and shortness of breath. Any new symptoms, repeated lows, or unexplained highs should be reviewed with the prescribing clinician to confirm technique, timing, and medication compatibility.

Compare With Alternatives

Basal insulin choices differ in duration, concentration options, and how tightly timing needs to be followed. Alternatives commonly considered include insulin glargine (long-acting), insulin detemir (long-acting), and NPH insulin (intermediate-acting). A clinician may select an option based on glucose patterns, hypoglycemia history, kidney or liver function, and practical factors such as injection volume and device preference.

When comparing options, it can help to separate the insulin molecule from the device. For example, insulin glargine is available in pen formats like Lantus SoloStar Pens, while insulin detemir may be supplied in cartridge systems such as Levemir PenFill Cartridges. Tresiba FlexTouch Pens are one basal option within this group, and any switch should be guided by the prescriber with a clear monitoring plan.

• Insulin glargine: long-acting basal insulin.
• Insulin detemir: long-acting basal insulin.
• NPH insulin: intermediate-acting option.

Pricing and Access

Total out-of-pocket cost can vary by strength, quantity, and dispensing pharmacy, and some people compare options when using a cash-pay approach. CanadianInsulin facilitates cross-border access by coordinating prescription documentation and routing eligible requests to dispensing partners. Ships from Canada to US may be available for eligible prescriptions, subject to location and documentation requirements. A list of related diabetes medication categories is available through the Diabetes Medications hub and the broader Diabetes Category list.

Cash-pay access is available when insurance coverage is not used.

Before starting, confirm the prescribed concentration (U-100 vs U-200), the number of pens, and the supplies needed for safe use (pen needles, sharps container, and a monitoring method). Tresiba FlexTouch Pens require a valid prescription, and some prescriptions may need clarification during review. For non-time-limited site information that may affect costs, see Promotions.

Why it matters: Concentration mismatches can lead to dosing errors.
