Saxenda is a daily injection. You take it once every day, not once a week. This is one of the most common points of confusion for people comparing weight loss medications, since some newer options like Wegovy are weekly injections. Saxenda uses a different active ingredient that stays active in your body for only about 13 to 15 hours, which is why it requires daily dosing.
How the Daily Dose Works
You inject Saxenda once a day at any time that works for you. It doesn’t need to be taken with food, and there’s no requirement to inject it at the same time each day, though many people find a consistent routine easier to remember. The injection goes just under the skin in your stomach area, upper thigh, or upper arm. You should rotate the exact spot within your chosen area each time to avoid developing lumps under the skin.
The 5-Week Ramp-Up Schedule
You don’t start at the full dose. Saxenda uses a gradual increase over five weeks to reduce the chance of nausea and other stomach-related side effects:
- Week 1: 0.6 mg daily
- Week 2: 1.2 mg daily
- Week 3: 1.8 mg daily
- Week 4: 2.4 mg daily
- Week 5 onward: 3.0 mg daily
The maintenance dose is 3.0 mg per day. The lower doses during the first four weeks exist only for the ramp-up period and aren’t intended as long-term treatment levels. For children and teens, the maintenance dose can be reduced to 2.4 mg if 3.0 mg causes too many side effects.
What Happens If You Miss a Day
Because Saxenda is a daily medication, missed doses come up more often than they would with a weekly injection. If you remember within 12 hours of your usual time, take the injection as soon as you can. If more than 12 hours have passed, skip that dose entirely and take your next one the following day at your normal time. Never double up to make up for a missed dose.
Missing three or more days in a row is a different situation. At that point, you may need to restart the ramp-up schedule rather than jumping back to your full dose. Contact your prescriber before resuming if this happens.
Why Saxenda Is Daily While Wegovy Is Weekly
The difference comes down to the active ingredients. Saxenda contains liraglutide, which your body clears relatively quickly, staying active for roughly 13 to 15 hours. Wegovy contains semaglutide, which remains active for about 165 hours, more than enough to last a full week between injections.
Both medications belong to the same drug class. They mimic a natural gut hormone that suppresses appetite and increases feelings of fullness. The weekly option is more convenient in terms of fewer injections, but Wegovy has its own slower ramp-up schedule that stretches over 16 weeks compared to Saxenda’s five. The trade-off with Saxenda is a daily commitment in exchange for reaching your maintenance dose faster.
Tracking Your Progress
Saxenda isn’t meant to be taken indefinitely without evaluation. The FDA label recommends checking your weight loss after 16 weeks on the medication. If you haven’t lost at least 4% of your starting body weight by that point, continued treatment is unlikely to produce meaningful results and should be reconsidered. For adolescents, the benchmark is a reduction in BMI of at least 1% after 12 weeks on the maintenance dose.
This built-in checkpoint is worth keeping in mind as you start. Daily injections are a real commitment, and knowing there’s a clear timeline for evaluating whether the medication is working can help you set realistic expectations from the beginning.
