Low blood sugar (hypoglycemia)

When is the risk of low blood sugar higher?
Low blood sugar is more likely to occur if you also take a sulfonylurea or use insulin. Your doctor may reduce the dose of these medicines before starting treatment with Ozempic.
Everyday life and use
What is important if nausea, vomiting, or diarrhea occur?
Nausea, vomiting, or diarrhea can lead to dehydration (fluid loss). It is important to drink plenty of fluids to help prevent dehydration. This is especially important if you have kidney problems. Talk to your doctor if you have questions or concerns.
Can I drive or operate machines?
Ozempic is unlikely to affect your ability to drive or use machines. If Ozempic is used in combination with a sulfonylurea or insulin, low blood sugar (hypoglycemia) can occur and may impair concentration. Do not drive or operate machines if you notice signs of low blood sugar.
What should I do if I miss an injection?
If it has been no more than 5 days since the missed dose, use Ozempic as soon as you remember and then inject the next dose as usual on your scheduled day of the week. If it has been more than 5 days since the missed dose, skip the missed dose and inject the next dose as usual on your scheduled day of the week. Do not use a double dose to make up for a missed dose.
