Can you overdose on Ozempic? 

by | Diet and Weightloss

It’s the diabetes medication changing the way the world regards obesity and its treatment. But like all pharmaceuticals, Ozempic (and its weight loss version, Wegovy) is not without risk.  

What is Ozempic?

Ozempic is a prescription medication called semaglutide which is approved to treat type 2 diabetes (T2DM) and also used “off-label” to treat obesity in some people.1-4 It belongs to the drug class of glucagon-like peptide-1 (GLP-1) receptor agonists.1-3 This means that it mimics the action of the body’s own naturally occurring GLP-1 hormones that help to regulate blood sugar levels and appetite.1-3

If you and your doctor have decided Ozempic is an appropriate treatment for you, you will be prescribed a weekly dose of this medication.1-3  While your Ozempic dose may be increased by your doctor after a month on the starting dose of 0.25mg once a week, it’s vital that any dose change is never done without the instruction of your prescribing doctor.1-3 Taking too much of any medication can lead to harm through overdosing. 

What can happen if I take too much Ozempic?

One of the biggest risks of taking too much Ozempic is that it can cause severe hypoglycaemia (low blood sugar).3-7 Hypoglycaemia can lead to loss of consciousness and even death.7 The risk of hypoglycaemia is more likely if you are using Ozempic for T2DM and take other diabetes medications.1-3 If you have T2DM, always follow your GP’s advice to monitor your blood sugar levels closely while taking Ozempic and discuss whether adjustments to your other diabetes medications are needed to reduce the risk of hypoglycaemia.

Regardless of whether you’re using Ozempic for T2DM or weight management, other complications of an Ozempic use are nausea, vomiting, diarrhoea, abdominal pain, constipation and pancreatitis (inflammation of the pancreas).1-6 In some people, complications are more likely to occur at higher doses, even under medical supervision. 

While the risk of pancreatitis has been known since clinical trials, more evidence is emerging that medicines such as Ozempic can be associated with other gastrointestinal complications that can have serious consequences such as gastroparesis (stomach paralysis) and ileus (bowel obstruction through more generalised intestinal paralysis).4-6

What should I do in the event of Ozempic overdose? 

If you suspect that you or someone you know has overdosed on Ozempic, seek medical attention immediately.1 One of the most important treatments for an Ozempic overdose may include emergency management of a person’s blood sugar levels.1 This could involve giving glucose, intravenous fluids or a sugar raising hormone called glucagon depending on whether the person is conscious. In some cases of Ozempic overdose, the person may need to be hospitalised for treatment and observation.
