From the Guidelines

If you miss an Ozempic (semaglutide) dose, take it as soon as you remember if it's within 5 days of your scheduled dose, as this approach is generally recommended for maintaining therapeutic blood levels and optimal blood sugar control 1. When considering the consequences of missing a dose of Ozempic, it's crucial to understand the medication's mechanism of action and its impact on blood glucose levels. Ozempic, a GLP-1 receptor agonist, works by mimicking the hormone GLP-1, which helps regulate blood sugar levels. The medication is typically administered once weekly, and maintaining a consistent schedule is vital for ensuring stable blood levels and optimal therapeutic effects.

Some key points to consider when missing a dose of Ozempic include:

  • Taking the missed dose as soon as possible if it's within 5 days of the scheduled dose
  • Skipping the missed dose if more than 5 days have passed and taking the next dose on the regularly scheduled day
  • Never taking a double dose to make up for a missed one, as this can increase the risk of adverse effects
  • Maintaining a consistent schedule to ensure stable blood levels of the medication and optimal blood sugar control

It's also important to note that missing multiple doses can reduce the medication's effectiveness in managing blood glucose levels. If you frequently miss doses, consider setting a weekly reminder or choosing a consistent injection day that works with your schedule. Additionally, contact your healthcare provider if you're unsure about what to do after missing a dose or if you've missed multiple doses, as they may need to reassess your treatment plan 1.

In the context of real-life clinical medicine, prioritizing morbidity, mortality, and quality of life is essential when managing type 2 diabetes with Ozempic. The medication has been shown to have beneficial effects on cardiovascular outcomes, as demonstrated in trials such as SUSTAIN-6 and PIONEER 6 1. Therefore, maintaining consistent dosing and minimizing missed doses is crucial for optimizing therapeutic outcomes and reducing the risk of cardiovascular events.

From the FDA Drug Label

If you miss a dose of OZEMPIC, take the missed dose as soon as possible within 5 days after the missed dose. If more than 5 days have passed, skip the missed dose and take your next dose on the regularly scheduled day. The consequences of missing a dose of Ozempic (semaglutide) are not explicitly stated in terms of side effects or health risks. However, the label provides instructions on how to manage a missed dose:

  • Take the missed dose as soon as possible within 5 days after the missed dose.
  • If more than 5 days have passed, skip the missed dose and take the next dose on the regularly scheduled day 2.

From the Research

Consequences of Missing a Dose of Ozempic (Semaglutide)

  • There is limited information available on the specific consequences of missing a dose of Ozempic (semaglutide) 3, 4, 5.
  • However, studies suggest that missing a dose of medication can lead to reduced efficacy and increased risk of adverse effects 3, 4, 5.
  • A study on the efficacy and safety of once-weekly semaglutide for the treatment of type 2 diabetes found that semaglutide achieved greater reduction from baseline in HbA1c compared to placebo, but the incidence of gastrointestinal adverse effects increased with semaglutide dose 6.
  • Another study compared the efficacy of olmesartan/amlodipine vs. perindopril/amlodipine in peripheral blood pressure after missed dose in type 2 diabetes, and found that a missed dose does not leave patients unprotected in both treatments, but a faster control with less dose increment is observed with olmesartan/amlodipine 7.
  • Pharmacometric modeling and simulation can be used to investigate the effect of various non-adherence scenarios on pharmacokinetic profiles and establish the optimum remedial dosing regimen in a time-effective and systematic way 5.

General Principles for Dealing with Missed Doses

  • Patients should be advised to take the missed dose as soon as possible, but if it is close to the time of the next dose, they should skip the missed dose and take the next dose at the scheduled time 4.
  • Pharmaceutical companies and regulatory authorities should produce clear and concise instructions on what patients should do if they miss doses, with supporting evidence where necessary 3.
  • Remedial strategies should be developed to inform patients of alternative dosing regimens in compensation for the loss of efficacy due to delayed or missed doses and minimize unintended clinical consequences 5.
