Dose:
  • Ozempic starting dose is 0.25 mg once weekly. This is with the Ozempic 0.25 mg, 0.5 mg/dose delivery pen. After 4 weeks, the dose should be increased to 0.5 mg once weekly. This is with the Ozempic 0.25 mg, 0.5 mg/dose delivery pen. After at least 4 weeks with a dose of 0.5 mg once weekly, the dose can be increased to 1 mg once weekly if blood glucose levels require improvement (person centred care). The Ozempic 1 mg/dose prefilled pen is required for this dose.
  • Ozempic 0.25 mg is not a maintenance dose.
  • Ozempic is administered once a week, on the same day each week, at any time of the day, without regard to meals.
  • Ozempic should be injected subcutaneously in the abdomen, in the thigh or in the upper arm.
  • Changing weekly dosage schedule: The day of week can be changed if the time between two doses is at least 3 days.
  • Missed dose: If a dose is missed, it should be administered as soon as possible and within 5 days after the missed dose. If more than 5 days have passed, the missed dose should be skipped and the next dose should be administered on the regular scheduled dose.
  • Hepatic impairment: No dose adjustment is required for this population. However, caution should be exercised when treating individuals with severe hepatic dysfunction due to the limited data.
  • Renal impairment. No dose adjustment is required with renal impairment. However, experience with severe (Cr <30 mL/min) renal impairment is limited. Therefore
  • semaglutide is not recommended for use in individuals with end-stage renal disease.
  • Gender. No dose adjustment is required based on gender.
Elderly:
  • No dose adjustment is required based on age.
Precautions:
Type 1 diabetes:
GLP1 agonists are not a substitute for insulin and should be used with caution in type 1 diabetes or for the treatment of diabetic ketoacidosis.
Acute pancreatitis:
Pancreatitis has been reported with use of all GLP-1 receptor agonists, including semaglutide. Patients should be informed of the symptoms of acute pancreatitis. Do not restart if confirmed.
Diabetic retinopathy:
In individuals with diabetic retinopathy treated with insulin and semaglutide, an increased risk of developing diabetic retinopathy complications has been observed. Caution should be used.
Heart failure:
There is no therapeutic experience in patients with congestive heart failure. It is therefore not recommended.
Hypoglycaemia:
Semaglutide does not cause hypoglycaemia on its own. However, when Ozempic is added to existing therapy of a sulfonylurea or insulin, a reduction in the dose of sulfonylurea or insulin should be considered to reduce the risk of hypoglycaemia.

Semaglutide is not recommended in children under the age o 18 years.
