Introduction
Semabrex 8 mg Injection contains semaglutide 8 mg in 3 mL and is supplied as an injectable formulation for subcutaneous use. It is a semaglutide product marketed by Natco Pharma Ltd.
Semaglutide is a GLP-1 receptor agonist used to improve blood glucose control in adults with type 2 diabetes mellitus, along with diet and exercise. The 8 mg/3 mL strength corresponds to a concentration of approximately 2.68 mg/mL.
Uses of Semabrex 8 mg
Semabrex 8 mg is used for:
Improving blood glucose control in adults with type 2 diabetes mellitus
Managing type 2 diabetes along with diet and exercise
The doctor decides the appropriate dose and duration of treatment.
How Semabrex 8 mg Works
Semabrex 8 mg contains semaglutide, which mimics the action of GLP-1, a hormone involved in blood glucose regulation.
It stimulates insulin release when blood glucose levels are elevated and reduces glucagon secretion. It also slows gastric emptying and can reduce appetite. These effects help improve blood glucose control in people with type 2 diabetes.
Interactions of Semabrex 8 mg with Other Medicines
Tell your doctor about all medicines you take before starting Semabrex 8 mg.
Insulin or sulfonylureas: Using semaglutide with these medicines can increase the risk of low blood sugar. Their doses may need adjustment.
Oral medicines: Semaglutide can delay gastric emptying and may affect the absorption of medicines taken by mouth.
Warfarin or other coumarin medicines: Your doctor may recommend closer INR monitoring when semaglutide treatment is started.
Other semaglutide-containing medicines or GLP-1 receptor agonists: Do not use these together with Semabrex unless specifically advised by your doctor.
Storage Conditions
Store Semabrex in a refrigerator at 2°C to 8°C.
Do not freeze.
Keep the medicine protected from light.
Keep it out of reach of children.
Follow the storage instructions provided on the product packaging.
How to Use
Semabrex 8 mg is administered as an injection under the skin (subcutaneous injection).
Semaglutide injections are generally given once a week, on the same day each week, as prescribed by your doctor.
It can be injected into the abdomen, thigh or upper arm.
Do not inject it into a vein or muscle.
Use only the dose prescribed by your doctor. Do not change the dose or frequency yourself.
If the product is supplied as a vial, use it only according to the instructions provided with the product and by your healthcare professional.
Safety Advice
Pregnancy
Semaglutide should not be used during pregnancy. If you are planning a pregnancy, speak to your doctor. Semaglutide should be discontinued at least 2 months before a planned pregnancy.
Breast Feeding
Tell your doctor if you are breastfeeding before using Semabrex. Your doctor will decide whether treatment is appropriate.
Lungs
Tell your doctor about any existing lung condition and inform your healthcare team that you use semaglutide before a procedure involving general anaesthesia or deep sedation. Delayed gastric emptying may increase the risk of aspiration during such procedures.
Liver
Tell your doctor if you have liver disease before using Semabrex. Your doctor will determine whether the medicine is suitable for you.
Alcohol
Alcohol can affect blood glucose control and may worsen gastrointestinal symptoms such as nausea and vomiting. Discuss alcohol consumption with your doctor.
Driving
Semaglutide does not usually affect the ability to drive. However, low blood sugar can affect driving ability, particularly when Semabrex is used with insulin or a sulfonylurea.

Semabrex may cause gastrointestinal side effects, particularly when treatment is started or the dose is increased.
