Description
What is Semaglutide Injection 0.25 mg / 0.50 mg?
Semaglutide 0.25 mg and 0.50 mg are strengths used in certain injectable semaglutide treatment regimens. Semaglutide acts on GLP-1 receptors involved in blood-glucose regulation, appetite and digestion. The correct dose, concentration and treatment schedule must be taken from the exact prescription and product labeling rather than inferred from vial size.
How Semaglutide Works
Semaglutide is structurally related to the naturally occurring GLP-1 hormone and activates the GLP-1 receptor. In approved uses, this can increase glucose-dependent insulin secretion, reduce glucagon when glucose is elevated, slow gastric emptying and influence appetite and satiety.
Understanding the 5 mL Vial Presentation
“5 mL” describes the listed vial volume, not an individual dose. The concentration of semaglutide in the vial and the amount prescribed determine administration. Never calculate a dose from vial volume alone.
Administration and Storage
Follow the dispensing label and the instructions supplied with the exact product. Do not use generic online dosing instructions to calculate an injection. Storage conditions can vary by formulation; verify temperature, light protection, beyond-use/expiration date and handling requirements on the actual packaging. Do not use a product that has been frozen, damaged, contaminated, improperly stored or expired.
Important Safety Information
Semaglutide is a GLP-1 receptor agonist and is not appropriate for every patient. Approved semaglutide products carry important warnings and contraindications. A healthcare professional should review the patient’s medical history, current medicines and treatment goals before use.
Common adverse reactions reported with approved semaglutide products are mainly gastrointestinal and can include nausea, vomiting, diarrhea, abdominal pain and constipation. Serious reactions can also occur, including pancreatitis, gallbladder problems, kidney injury related to volume depletion, severe gastrointestinal reactions, hypersensitivity reactions and complications of diabetic retinopathy in some patients.
Approved semaglutide labeling includes a boxed warning concerning the risk of thyroid C-cell tumors observed in rodents. Semaglutide products are contraindicated in people with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). The relevance of the rodent findings to humans has not been established.
Tell your healthcare professional about planned surgery or procedures requiring general anesthesia or deep sedation, and discuss pregnancy or plans for pregnancy. This summary is not a substitute for the complete prescribing information for the exact product supplied.
5. Who Should Speak With a Healthcare Professional Before Use?
- Anyone considering semaglutide should have the exact product, indication and dose assessed by a qualified healthcare professional.
- Discuss a personal or family history of medullary thyroid carcinoma (MTC) or MEN 2, previous pancreatitis, gallbladder disease, kidney problems, severe gastrointestinal disease, diabetic retinopathy and serious allergies.
- Tell the prescriber about insulin, sulfonylureas and other medicines that can affect blood glucose, as well as other oral medicines when using oral semaglutide.
- Discuss pregnancy, plans for pregnancy or breastfeeding before treatment. Current FDA labeling advises discontinuation of semaglutide at least 2 months before a planned pregnancy because of its long washout period.
- Tell healthcare providers about semaglutide before planned surgery or deep sedation because GLP-1 receptor agonists delay gastric emptying and pulmonary aspiration has been reported.
