Mounjaro (Tirzepatide)

Tirzepatide, the active ingredient in Mounjaro, is a dual GIP and GLP‑1 receptor agonist presented as a 2 mg/mL subcutaneous injection solution (prefilled pen) for subcutaneous use. It treats type 2 diabetes mellitus in adult patients.

GNH USA supplies Mounjaro as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Mounjaro is indicated for the management of type 2 diabetes mellitus, a chronic metabolic disorder characterized by insulin resistance and hyperglycaemia.

Type 2 diabetes mellitus: improves glycaemic control, lowers HbA1c and may aid in weight reduction.

Mounjaro may cause a range of adverse reactions, which are grouped by frequency.

Common Side Effects: - Nausea - Vomiting - Diarrhoea - Decreased appetite

Serious or Rare Side Effects: - Pancreatitis - Severe allergic reaction (anaphylaxis) - Thyroid C‑cell tumour risk (observed in rodent studies) - Hypoglycaemia, especially when combined with insulin or sulfonylureas

Before prescribing Mounjaro, several safety considerations should be reviewed. - Renal function: assess before initiating and monitor periodically. - Pancreatitis: discontinue if signs of pancreatitis develop. - Thyroid disease: avoid in patients with medullary thyroid carcinoma or MEN2. - Pregnancy and lactation: safety not established; avoid unless benefit outweighs risk. - Drug interactions: review concomitant medications for additive hypoglycaemic risk. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Mounjaro can interact with several drug classes; awareness of the interaction level is essential.

Major Interactions (Avoid): - Insulin: risk of severe hypoglycaemia. - Sulfonylureas: increased hypoglycaemia. - Meglitinides: additive hypoglycaemic effect. - Other GLP‑1 receptor agonists: overlapping mechanisms, not recommended.

Moderate Interactions (Monitor Closely): - Warfarin: possible effect on INR, monitor coagulation. - Oral contraceptives: delayed gastric emptying may reduce absorption. - Diuretics: monitor renal function and electrolytes.
