Indications & Clinical Uses

Semglee 300IU/3ml pen is a long-acting insulin analog prescribed to improve glycemic control in adults and pediatric patients with diabetes mellitus. It provides a steady release of insulin over 24 hours, helping maintain blood sugar levels between meals and overnight. Often prescribed alongside rapid-acting insulin for mealtime coverage. Used for type 1 diabetes and type 2 diabetes when oral medications are insufficient.

Side Effects

Semglee works by replacing the insulin your body would normally produce. It helps cells absorb glucose from the bloodstream, lowering blood sugar levels. Users may notice improved energy levels and reduced symptoms of high blood sugar such as frequent urination or excessive thirst. Effects are typically gradual over several days of consistent use.

Precautions & Warnings

Keep Semglee refrigerated between 2–8°C until first use; do not freeze. After opening, it may be stored at room temperature below 30°C for up to 28 days. Protect from direct heat and light. Always check the pen for particles or discoloration before use. Rotate injection sites to prevent lipohypertrophy or skin changes.

Avoid Interactions

Alcohol may increase or decrease blood sugar effects; monitor levels closely. Certain medications like oral diabetes drugs, ACE inhibitors, or beta-blockers can alter insulin requirements. Corticosteroids and diuretics may reduce insulin sensitivity. Always inform your healthcare provider about all medications and supplements being used.
