How long does one Saxenda pen last?

Saxenda is administered using an injection pen that you self-administer daily. But how long does one pen actually last? That depends entirely on your dosage, which changes over the course of treatment. In the first few weeks, you use less per injection than toward the end, which means that one pen lasts longer at the beginning than later in the process. In this blog, you’ll read exactly how that works, what to expect during the titration schedule, and how Goodweigh helps you plan your supply smoothly.

How many doses are in one Saxenda pen?

Each Saxenda pen contains 3 milliliters of solution with a concentration of 6 mg per milliliter. That amounts to 18 mg of liraglutide per pen. Depending on the dosage you’re currently using, one pen contains between six and ten daily doses. At the starting dose of 0.6 mg per day, you can theoretically get about thirty doses per pen, which amounts to five weeks of use. But as your dose increases—which happens weekly—the duration of use per pen also becomes shorter.

This is one of the points that sometimes surprises users: a pen that lasts well over two weeks in week one is already empty after just six days in week five. That is not a mistake or a defect; it is exactly the intention of the titration schedule.

How does the dosage affect the duration of use of a pen?

The dosage schedule for Saxenda is designed so that your body gradually gets used to the active ingredient liraglutide. You start with 0.6 mg per day in week one and increase by 0.6 mg each week until you reach the maximum maintenance dose of 3.0 mg per day in week five. This gradual titration process helps minimize side effects such as nausea and fatigue, which most commonly occur when the dose is increased too quickly.

The relationship between dosage and pen usage is simple: the higher the dosage, the more liquid per injection, and the faster the pen runs out.

How long does Saxenda last on average during the first few weeks?

In the first month of your treatment, you’ll need an average of three pens, even though that might seem like a lot. This aligns with the titration schedule: in weeks one and two, you use relatively little per pen, but as your dose increases in weeks three and four, you’ll go through your pens more quickly. Goodweigh therefore supplies three pens as standard in the first month, so you can complete the entire titration phase without interruptions. It is important not to discontinue treatment or skip a day because of an empty pen. A doctor will help you plan your deliveries so that you always have a sufficient supply.

How long does a pen last at the maximum dose?

Starting in week five, you’ll use the full maintenance dose of 3.0 mg per day. At this dose, one pen will run out after about six days. This is normal and fully in line with how the treatment is structured. In practice, this means that in the second month of treatment, you’ll need five pens per month to maintain the 3.0 mg daily dose. Goodweigh delivers these automatically each month, so your treatment can continue uninterrupted.

What if your pen seems to run out sooner?

Occasionally, users report that their pen seems to run out faster than expected. There are several possible causes for this. First, air in the pen: follow the official instructions for performing the “flow check” before each injection. This involves squirting out a small amount of medication, which removes any air bubbles. Second, incorrect administration may be a factor; if the needle isn’t inserted properly or the skin isn’t held firmly enough during the injection, medication may be lost. Third, some users misread the dosage on the pen, causing them to accidentally administer too much.

If in doubt, it is always wise to contact your doctor via Goodweigh. They can assess whether it is a user error or another issue. Always consult the package insert that comes with your pen.

Clarity about your treatment with Saxenda

How long a pen lasts depends entirely on your personal dosage and the stage of your treatment. In the first few weeks, a pen will last longer; at the full dosage of 3.0 mg, one pen will be used up after six days, and that is exactly as it should be.
