Introduction
Sematrinity 4mg Injection contains Semaglutide, a GLP-1 receptor agonist used to improve blood sugar control in adults with insufficiently controlled type 2 diabetes mellitus, along with diet and exercise.
Sematrinity 4mg Injection contains Semaglutide 4 mg/3 mL and is supplied as a multi-dose prefilled pen designed to deliver a 1 mg dose.
Uses of Sematrinity 4mg Injection
Sematrinity 4mg Injection is used to:
Improve blood sugar control in adults with type 2 diabetes mellitus: It is used as an adjunct to diet and exercise.
Support long-term diabetes management: It may be prescribed when additional glycaemic control is needed.
Sematrinity is not used to treat type 1 diabetes or diabetic ketoacidosis.
How Sematrinity 4mg Injection Works
Sematrinity 4mg Injection contains Semaglutide, which mimics GLP-1, a natural hormone involved in blood glucose regulation.
It increases insulin secretion when blood glucose levels are high and reduces glucagon release. It also slows stomach emptying and may increase feelings of fullness.
Interaction of Sematrinity 4mg Injection with Other Medicines
Tell your doctor about all prescription medicines, over-the-counter medicines, vitamins, supplements and herbal products you take.
Insulin or sulfonylureas: These can increase the risk of low blood sugar when combined with Sematrinity.
Oral medicines: Delayed stomach emptying may affect the absorption of some oral medicines.
Warfarin or other coumarin medicines: Closer monitoring may be required.
Other GLP-1 receptor agonists: Do not use Sematrinity with another Semaglutide-containing medicine or GLP-1 receptor agonist unless prescribed.

How to Use
Use Sematrinity 4mg Injection exactly as prescribed by your doctor.

Safety Advice
Pregnancy
