Sematrinity 4mg Pre-filled Pen is an antidiabetic medicine (GLP-1 receptor agonist) used to improve blood sugar control in adults with type 2 diabetes. It helps lower blood sugar by increasing insulin release when blood sugar levels are high, reducing the amount of sugar made by the liver, and slowing digestion.
Sematrinity 4mg Pre-filled Pen is given as an injection under the skin, usually once a week. Use it on the same day every week, preferably at the same time, to help maintain consistent blood sugar control. Follow your doctor’s instructions carefully and do not change your dose without medical advice.
The most common side effects of Sematrinity 4mg Pre-filled Pen include nausea, vomiting, diarrhea, constipation, stomach pain, indigestion, and reduced appetite. These side effects are usually mild and tend to improve as your body gets used to the medicine. Eating smaller meals, avoiding greasy or spicy foods, and drinking plenty of fluids may help reduce stomach-related side effects. If any of these symptoms persist or get worse, contact your doctor.
Before using Sematrinity 4mg Pre-filled Pen, tell your doctor if you have or have ever had pancreatitis, diabetic eye disease (diabetic retinopathy), kidney problems, or any severe stomach or intestinal disorders. Do not use this medicine if you are allergic to semaglutide or any of its ingredients. This medicine is not intended for the treatment of type 1 diabetes and is not a substitute for insulin.
Tell your doctor about all the medicines, vitamins, and herbal supplements you are taking, as some medicines, especially insulin or sulfonylureas, may increase the risk of low blood sugar when used together with Sematrinity 4mg Pre-filled Pen. Avoid excessive alcohol consumption as it may affect your blood sugar levels. This medicine is not recommended during pregnancy, and women planning pregnancy should stop treatment at least 2 months before becoming pregnant. It is also not recommended while breastfeeding unless advised by your doctor.
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
