Glyset R Injection

What is Glyset R?

Glyset R is a rapid-acting insulin analog (Insulin Aspart) manufactured by Incepta Pharmaceuticals Ltd., supplied in a vial for use with a syringe. It works faster and has a shorter duration than regular human insulin, allowing it to be taken closer to mealtimes for improved post-meal blood glucose control.

Generic Name and Composition

Each mL contains 100 IU of Insulin Aspart (rDNA origin), supplied in a 10 mL vial.

Indications

• Type 1 diabetes mellitus, as part of a basal-bolus insulin regimen
• Type 2 diabetes mellitus when oral antidiabetic agents are insufficient to control blood glucose
• Gestational diabetes, as directed by a physician

How It Works — Mechanism of Action

Insulin aspart is a rapid-acting insulin analog with a faster onset and shorter duration of action than regular human insulin, due to a modification that reduces self-association. It lowers blood glucose by promoting cellular glucose uptake and suppressing hepatic glucose production, closely mimicking the body's natural mealtime insulin response.

Dosage and Administration

• Dosage is strictly individualized by a physician based on blood glucose monitoring, body weight, and meal patterns.
• Administered by subcutaneous injection using a syringe, typically immediately before or just after a meal (0-15 minutes).
• The solution should appear clear and colorless — do not use if cloudy, discolored, or containing particles.
• Rotate injection sites within the same body region (abdomen, thigh, upper arm) to reduce lipodystrophy.
• Use a new sterile syringe and needle for each injection.

Side Effects

Common: Hypoglycemia, injection site reactions (redness, swelling, itching), lipodystrophy with repeated injections at the same site.

Uncommon: Weight gain, peripheral edema (especially when starting therapy).

Rare: Severe allergic reactions (generalized rash, angioedema, anaphylaxis), hypokalemia.

Drug Interactions

May increase hypoglycemia risk: Oral antidiabetic agents, ACE inhibitors, salicylates, alcohol.

May reduce insulin effect / raise blood glucose: Corticosteroids, thiazide diuretics, thyroid hormones, oral contraceptives.

Other considerations: Beta-blockers may mask symptoms of hypoglycemia; inform your doctor of all medicines you are taking.

Contraindications

• Known hypersensitivity to insulin aspart or any excipient
• Episodes of hypoglycemia requiring caution in dosing adjustment

Pregnancy and Lactation

Insulin aspart is generally considered safe for use during pregnancy and breastfeeding under close physician supervision. Dose requirements often change during pregnancy and require close monitoring.

Precautions and Warnings

• Never share vials or syringes between patients due to infection transmission risk.
• Inject close to mealtime (0-15 minutes before eating) — delaying the meal after injection increases hypoglycemia risk.
• Closely monitor blood glucose, especially when changing dose, insulin brand, meal timing, or activity/diet patterns.
• Be aware of signs of hypoglycemia (sweating, palpitations, confusion) and carry a fast-acting sugar source.
• Store correctly — refrigerate unopened vials, keep in-use vials at room temperature, away from direct heat and sunlight.

Overdose

Overdose may cause severe hypoglycemia, with symptoms ranging from sweating and confusion to seizures and loss of consciousness. Mild cases can be managed with oral glucose; severe cases require immediate medical attention, including intravenous glucose or glucagon administration.

Storage Instructions

• Store unopened vials in a refrigerator (2-8°C); do not freeze.
• Once in use, the vial may be kept at room temperature (below 30°C) for up to 4 weeks, away from direct heat and light.
• Keep out of reach of children.
• Do not use after the expiry date printed on the pack.

Frequently Asked Questions

Q1: When should I inject Glyset R relative to meals?
It is typically injected 0-15 minutes before, or immediately after, a meal due to its rapid onset — follow your physician's specific guidance.

Q2: How is the vial different from the Penset?
Both contain the same insulin aspart; the vial requires a separate syringe for dosing, while the Penset offers a more portable, prefilled pen device.

Q3: How is Glyset R different from Maxsulin R?
Glyset R (insulin aspart) is a rapid-acting insulin analog with a faster onset and shorter duration than Maxsulin R (regular human insulin), allowing more flexible mealtime dosing.

Q4: How does Glyset R compare to Glyset Mix?
Glyset R contains only rapid-acting insulin aspart for mealtime coverage, while Glyset Mix is a premixed formulation combining rapid-acting and intermediate-acting (protamine-crystallized) insulin aspart for combined mealtime and basal coverage.
