Ozempic is used in combination with diet and exercise to help improve glycemic control and reduce the risk of cardiovascular complications (CV death, nonfatal stroke and nonfatal myocardial infarction).

Injecting insulin

When administering Ozempic, the following points should be considered:

  • Do not inject into the same location each time. Rotate injection sites.
  • Do not inject where the skin is thickened, has pits or lumps as this can affect the effectiveness of the medication.
  • Do not inject where the skin is bruised, scaly, hard, tender or damaged.

Risk of Thyroid C-Cell Tumors

If serum cacitonin is measured and found to be showing elevated or thyroid nodules from a physical examination or neck imaging, patients should be referred to an endocrinologist. Patients should be informed that Semaglutide causes thyroid C-cell tumors in rodents and that this has not been conclusive in humans. Patients must report any symptoms of hoarseness, dysphagia, dyspnea or a lump in the neck to their physician.


Patients should be informed of the risks of pancreatitis. In glycemic control trials, acute and chronic pancreatitis has been reported. Patients need to be aware of signs and symptoms of pancreatitis which can include ongoing severe abdominal pain and vomiting. If signs of pancreatitis are confirmed, Ozempic treatment should be discontinued and your doctor should be consulted.

Diabetic Retinopathy

In a 2-year trial, more complications of diabetic retinopathy occurred in patients taking Ozempic (3.0%) vs those taking the placebo (1.8%). Patients in the trial had type 2 diabetes and high cardiovascular risk. It was found that the patients who had a high risk of diabetic retinopathy were predisposed based on their family history compared to those without. This is why patients with a history of diabetic retinopathy should be monitored closely.

If patients experience a rapid improvement in glucose control, this may indicate a worsening of diabetic retinopathy.


When Ozempic is used in combination with insulin or insulin secretagogues (ie sulfonylureas), patients were at higher risk of hypoglycemia (high blood sugar levels).

Do not share Ozempic pens

Ozempic pens should no be shared among patients even if they show similar symptoms and the needle has been changed. Sharing pens can lead to spreading infection and transmission of blood-borne pathogens.

Acute Kidney Injury

Reports have shown that patients treted with GLP-1 receptor agonists experienced acute kidney injury and worsening of chronic renal failure. As a result patients would require hemodialysis. Most of the reported events happened with patients have shown symptoms of vomiting, diarrhea, nausea and dehydration have occurred. Renal function should be monitored closely in patients for severe adverse gastrointestinal reactions in patients taking escalated doses.


If hypersensitivity occurs, patients should discontinue use and monitor until symptoms ar resolved. Serious symptoms of hypersensitivity include angioedema and anaphylaxis. Patients with a history of these two reactions should be treated with caution and treated with another GLP-1 receptor agonist. Patients who have a history of angioedema or anaphylaxis with other GLP-1 receptors should be treated with caution.


Pregnant women or those planning pregnancy should be advised of the potential risks to a fetus. Consult your doctor if you are pregnant or planning pregnancy. If diabetes is poorly managed during pregnancy, this can increase the risk of complications such as ketoacidosis, preeclampsis, birth defects, macrosomnia, preterm delivery, spontaneous abortions, delivery complications and stillbirth.

Renal Failure and Dehydration

Patients should be advised by their physicians about the possible risk of dehydration do to gastrointestinal adverse reactions if they are using Ozempic. Patients should avoid fluid depletion. Doctors should explain the possible symptoms of renal impairment and the possible requirement of dialysis if renal failure occurs.


Typically patients see their blood glucose levels start dropping after 5 weeks and a maximum effect within 3-6 months of use.
