Life gets busy. If you’re juggling work, family, or simply lost track of time, it’s easy to miss a weekly GLP-1 shot. But once you realize it, the questions come fast: Did I mess up my progress? Should I take it now or wait? Understanding what happens if you miss a dose of GLP-1 is important—not just to stay safe, but to keep your momentum moving forward.
What To Do If You Miss A GLP-1 Dose
GLP-1 medications are typically administered once weekly, so a missed dose can feel like a big deal. However, these drugs are designed with long half-lives, which means they stay in your system for several days. Still, timing matters. Here’s what you should do:
- If it’s within 48 hours of your scheduled time, take the missed dose as soon as you remember. Then continue with your next dose on your regular day.
- If more than 2 days have passed, skip the missed dose completely. Wait until your next scheduled injection. Do not double up or inject two doses close together.
- Track the miss in a journal or app. This helps your provider understand your dosing history and make informed adjustments if needed.
Missing a dose occasionally won’t undo your progress, but consistency is critical. Repeated missed doses can cause blood sugar levels to fluctuate, increase hunger, and stall your weight loss results. Worse, it may disrupt your body’s hormonal rhythm and lead to more pronounced side effects when you resume, as noted in GLP-1 treatment guidance.
Also, make sure to dispose of the missed-dose pen properly—especially if it’s been unrefrigerated for too long or exposed to heat. Never try to “make up” for a missed dose with extra medication later. Check out these tips for properly storing and refrigerating semaglutide so you don’t risk using a compromised dose.
Could A Missed Dose Affect Your Cycle or Hormones?
For some women, the question isn’t just about blood sugar or appetite. A common concern we hear is: Can a missed GLP-1 dose affect my period?
While not a direct side effect, some women have reported GLP-1 missed period incidents, often after changes in dosing. These medications can influence body weight, appetite, and insulin sensitivity, which in turn may impact reproductive hormones.
A missed dose may:
- Disrupt the hormonal balance your body was adapting to
- Delay or alter your menstrual cycle
- May worsen cycle issues after weight loss or low calorie intake
It’s also worth noting that some women experience temporary cycle changes just from being on GLP-1 therapy, even if they haven’t missed a dose. These changes are usually not dangerous but should be monitored. If irregular periods persist after multiple missed doses or if you’re concerned about fertility or hormone balance, consult your provider for a personalized evaluation.
