What is Semaglutide for?
Semaglutide belongs to a class of medication called glucagon-like peptide-1 agonists. It works by mimicking a hormone to make the pancreas produce more insulin and less glucagon to control blood sugar level. It is used to treat type 2 diabetes mellitus and prevent cardiovascular disease in diabetic patients.
How to use it?
Semaglutide is administered subcutaneously via pre-filled injection pens. The usual dose is 0.25 mg once weekly for 4 weeks, then increases to 0.5 mg once weekly. It may be increased to maximum 1 mg once weekly if additional glycemic control is needed after at least 4 weeks of the 0.5-mg weekly dosage.
What are the side effects of Semaglutide?
Common side effects of Semaglutide include nausea, abdominal pain, constipation, decreased appetite, vomiting, and diarrhea.
Who should not take Semaglutide?
– People who are allergic to Semaglutide or any component of the formulation
– Patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN2), or personal or family history of medullary thyroid carcinoma (MTC)
– Non-drug management, including diet and exercise, also plays an important role in controlling both diabetes and weight.
– If you use insulin in addition to Semaglutide, do not mix them into the same syringe. You may give the shots in the same area (including your stomach), but do not give the shots right next to each other.
– For each new prefilled pen, prime the needle before the first injection by turning the dose selector to the flow check symbol and injecting into the air (priming is not required for subsequent injections).
– Change (rotate) your injection site with each injection. Do not use the same site for each injection.
– Use a new needle for each injection and do not share pens between patients.
– Once injected, continue to depress the button until the dial has returned to 0 and for an additional 6 seconds. Then, remove the needle.
– Store your new, unused medicine pen in its original carton in the refrigerator. You may store the opened medicine pen in the refrigerator or at room temperature for 56 days.
