Insuman Comb 50 (Insulin Human)

Insuman Comb 50 is a premixed insulin that provides both basal and prandial glucose control for diabetes management.

• Type 1 diabetes mellitus: provides basal and rapid‑acting insulin to maintain target glycaemic levels.
• Type 2 diabetes mellitus: supplements oral agents when additional glucose lowering is required.
• Hyperglycaemic emergencies: delivers a rapid reduction of plasma glucose during acute episodes.

• Insulin Human binds to insulin receptors on cell membranes, activating the receptor’s intrinsic tyrosine kinase activity. This triggers intracellular signaling cascades that promote translocation of GLUT‑4 transporters to the cell surface, enhancing glucose uptake in muscle and adipose tissue, while suppressing hepatic gluconeogenesis and glycogenolysis, thereby lowering blood glucose concentrations.

Insuman Comb 50 may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Hypoglycaemia: symptoms of low blood sugar such as shakiness, sweating, or confusion.
• Weight gain: modest increase in body weight with chronic use.
• Injection‑site reactions: redness, swelling, or itching at the injection site.
• Lipodystrophy: localized changes in fat tissue under the skin.
• Localised allergic reactions: mild rash or urticaria.

Serious or Rare Side Effects

• Severe hypoglycaemia: loss of consciousness or seizures requiring emergency assistance.
• Anaphylaxis: life‑threatening systemic allergic response.
• Insulin edema: swelling of extremities due to fluid retention.
• Hypokalemia: low potassium levels that may affect cardiac rhythm.
• Hypocalcemia: reduced calcium levels, potentially causing neuromuscular symptoms.

When using Insuman Comb 50, several safety considerations should be observed.

• Blood‑glucose monitoring: check levels regularly to adjust dose and avoid hypoglycaemia.
• Illness or stress: may require temporary dose increase; consult a healthcare professional.
• Renal or hepatic impairment: use caution and consider dose modification.
• Pregnancy and lactation: safety data are limited; discuss risks with a physician.
• Hypoglycaemia history: avoid use if patient has recurrent severe episodes.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake the vial.

Insuman Comb 50 can interact with several medicines, altering its glucose‑lowering effect.

Major Interactions (Avoid)

• Sulfonylureas or meglitinides: additive risk of severe hypoglycaemia.
• Beta‑adrenergic blockers: may mask hypoglycaemia symptoms.
• ACE inhibitors or ARBs: can potentiate insulin’s glucose‑lowering action.

Moderate Interactions (Monitor Closely)

• Corticosteroids: increase blood glucose, may require higher insulin dose.
• Thiazide diuretics: can raise glucose levels modestly.
• Oral contraceptives: may affect insulin sensitivity.
• Alcohol: can cause unpredictable glucose fluctuations.
• Lipid‑lowering agents (e.g., fibrates): occasional reports of altered insulin requirements.
