When you start a new health journey, it’s smart to know how to handle your medication the right way. Using a helpful treatment like Semaglutide means that storing it correctly is very important for your safety and for getting the best results. You might be looking at your medicine and asking, does semaglutide expire after 28 days? That’s a great question, and the answer is not always a simple yes or no.
It really depends on which type of Semaglutide you are using. This guide will give you the clear answers you need to feel confident and safe.
The 56-Day Rule: Expiration for Branded Pens (Ozempic & Wegovy)
First, let’s talk about the well-known brand-name pens, like Ozempic and Wegovy. These come in pre-filled pens that are sealed by the company that makes them.
For these specific pens, the rule is actually 56 days. That means after you use a pen for the first time, you can continue to use it for up to 56 days, or 8 weeks.
This is the official Ozempic pen expiration and Wegovy expiration after opening rule from the manufacturer. Just make sure you are storing it correctly during that time.
The 28-Day Rule: Understanding Compounded Semaglutide
Now, let’s talk about a different form of this medication. This is where the 28-day rule usually comes into play.
What is Compounded Semaglutide?
Sometimes, a special kind of pharmacy, called a compounding pharmacy, prepares medication specifically for a patient. This is called compounded Semaglutide. It usually comes in a small glass bottle, called a vial, instead of a pre-filled pen.
Why the Shorter Expiration Date?
This is the most important part to understand. The question “does semaglutide expire after 28 days” is most often about these compounded vials. The reason for the shorter time is all about keeping you safe.
Compounded medicines have something called a “Beyond-Use Date,” or BUD. Think of it like an expiration date for your safety. Each time you take a dose, you have to put a new, clean needle through the vial’s rubber stopper.
Even when you are very careful, doing this over and over can create a tiny risk of germs getting inside. To make sure the medicine stays perfectly clean and safe, these vials have a shorter life. The special ingredients that keep it sterile, called preservatives, only work for a limited time. This compounded semaglutide shelf life is often 28 days to be extra safe.
Why You Should Never Use Expired Semaglutide
It can be tempting to use medication past its expiration date, but it’s a bad idea. There are two big risks when it comes to using expired semaglutide.
First, it might not work anymore. Over time, the medicine inside can start to break down. This means it gets weaker, and you won’t get the full benefit from your dose.
Second, and most importantly, it could be unsafe. After the expiration date or BUD, especially with a vial you’ve been using, there is a small chance that bacteria could start to grow inside. This could make you very sick if you inject it. Your health is not worth the risk.
How to Store Semaglutide Correctly: A Step-by-Step Guide
Knowing how to store semaglutide is easy once you know the rules. It helps keep your medicine safe and effective from the first dose to the last.
Before Your First Use
Before you use your Semaglutide for the very first time, it should be kept in the refrigerator. Be careful not to let it freeze! A frozen vial or pen should be thrown away.
After Your First Use
This is where the rules can change a little bit.
-
Branded Pens: After your first use, you can keep your pen in the fridge or at room temperature for up to 56 days. Just make sure it doesn’t get too hot.
-
Compounded Vials: It’s usually best to keep these in the refrigerator even after you start using them. Always follow the specific instructions that come from your pharmacy.
Also, always keep your medication out of direct sunlight. Heat and light are enemies of many medicines and can make them break down faster.
