Saxenda — weight loss with liraglutide: price, dosage and side effects

01 Mar

Saxenda was the first GLP-1-based drug to be approved specifically for weight loss in Sweden. Although newer drugs such as semaglutide and tirzepatid have taken over the headlines, Saxenda is still widely prescribed — especially to patients who cannot tolerate the newer options. We go through how liraglutide works, how much Saxenda costs in Sweden in 2026, how to dose correctly and which side effects you should be aware of.

Liraglutide — the substance behind Saxenda

Saxenda contains liraglutide at a dose of 3.0 mg per day. The same substance is found in Victoza (1.8 mg), which is used in type 2 diabetes. Liraglutide was thus first in the class of GLP-1 receptor agonists for weight control, with EU approval already in 2015.

The mechanism is the same as for newer GLP-1 preparations: liraglutide binds to GLP-1 receptors in the brain, intestine and pancreas. Appetite is suppressed, gastric emptying is delayed and blood sugar is stabilized after a meal. The effect on appetite is most clearly felt between meals — the hunger panic that normally occurs three to four hours after breakfast is significantly mitigated, and the need for snacks is reduced.

The difference to semaglutide (Ozempic/Wegovy) and tirzepatid (Mounjaro) is mainly in the half-life. Liraglutide has a half-life of approximately 13 hours, requiring daily dosing. Semaglutide remains active in the body for about a week, and tirzepatide has similar pharmacokinetics. The daily injection is Saxenda’s biggest practical drawback — but for some patients it also means more flexibility in dosing. Do you feel bad one day? You can simply pause and resume the next day without disrupting a weekly schedule.

Liraglutide acts on the same receptors as the body’s own GLP-1 hormone, but with a modified molecular structure that makes it resistant to rapid degradation. It provides a more even effect over the day compared to the natural hormone, which breaks down within minutes.

Saxenda dosage — daily escalation schedule

Unlike weekly preparations such as Wegovy, Saxenda requires an injection every day. The escalation takes place over five weeks to reduce the risk of nausea and other gastrointestinal complaints.

|Week|Dose per day|Number of clicks|

|Week 1|0.6 mg|Starting dose|

|Week 2|1.2 mg|First raise|

|Week 3|1.8 mg|Equivalent to Victoza’s maximum dose|

|Week 4|2.4 mg|Penultimate step|

|Week 5+|3.0 mg|Full maintenance dose|

The injection is given subcutaneously — in the abdomen, thigh or upper arm — at any time of the day, with or without food. We recommend choosing a fixed time and sticking to it. Many people prefer the evening, because possible nausea then occurs during sleep rather than in the middle of the working day. The pen is delivered ready to use and requires no mixing — you set the dose via a rotary control, attach a new needle and inject. The entire procedure takes less than a minute.

When should you evaluate the effect?

Novo Nordisk, the manufacturer, recommends an evaluation after 12 weeks of treatment at the full dose (3.0 mg). If at that point you have not lost at least 5% of your body weight, you should discuss with your prescriber whether it makes sense to continue. Study data show that patients who do not respond during the first 12 weeks rarely achieve clinically significant weight loss even with longer treatment — response in the early phase is thus a strong predictor of long-term outcome. It’s not a disadvantage — it gives you a clear decision basis instead of months of uncertainty.

Saxenda side effects — what do the studies say?

The side effect profile of Saxenda is similar to other GLP-1 drugs, with the gastrointestinal tract being the primary area of ​​concern. Because liraglutide is dosed daily, however, the side effects can be experienced as more constant compared to weekly preparations, where the discomfort is often concentrated in the first days after injection.

The most commonly reported side effects in the SCALE studies:

• Nausea — approximately 40% of participants, most of whom described it as mild to moderate

• Diarrhea — around 21%, usually passing within the first few weeks

• Constipation — about 19%, may require increased fluid intake and fiber-rich foods

• Vomiting — 16%, most common during the escalation phase

• Pain at injection site — 14%, relieved by rotating injection site

More serious side effects include pancreatitis (inflammation of the pancreas), gallbladder problems, and palpitations. The risk of pancreatitis is low but not negligible — severe, persistent abdominal pain radiating to the back requires immediate medical evaluation. Gallstones occur to an increased degree with rapid weight loss regardless of the method, but liraglutide can further increase that risk.

An aspect that is rarely mentioned: liraglutide can interact with other blood sugar-lowering drugs. If you take sulphonylureas or insulin in parallel with Saxenda, the risk of hypoglycaemia increases. Your prescriber should adjust the doses of these preparations before starting treatment.

Practical tips to deal with the most common complaints: eat slowly and in smaller portions, avoid strongly spiced and fatty foods during the first weeks, and make sure to drink enough water — at least 1.5 liters per day. If the nausea is bothersome at 3.0 mg, you can go back to 2.4 mg for a week and then try to increase again.

Saxenda price — how much does the treatment cost in Sweden?

Saxenda is one of the more expensive injectable weight loss drugs on the Swedish market, especially in terms of the daily dosage.

The price per package (five pre-filled pens of 3 ml) in 2026 is approximately SEK 2,800–3,200 via Swedish pharmacies. At full dose (3.0 mg/day), one pen lasts for six days, and one package thus covers approximately one month. During the ramp-up phase, consumption is lower and one pack can last longer.

Without medication benefit, the annual cost is around SEK 34,000–38,000. Saxenda is not generally subsidized for weight loss alone in Sweden — the subsidy applies primarily to type 2 diabetes in combination with specific criteria.

Compared to newer alternatives, Saxenda ends up in an intermediate position in terms of price. Wegovy is more expensive per month but only needs to be dosed once a week, which some patients value highly from a convenience point of view. The cost per kilogram of body weight lost is difficult to calculate in general, but study data suggest that semaglutide and tirzepatide provide more weight loss per dollar invested due to their higher average results. Those looking for liraglutide as a research peptide will find significantly lower price levels, but this requires their own preparation and some experience.

Saxenda compared to newer GLP-1 drugs

So how does Saxenda stack up against the competition? We have compiled the most important differences:

|Parameter|Saxenda (liraglutide)|Wegovy (semaglutide)|Mounjaro (tirzepatid)|

|Dosage|Daily injection|Once per week|Once per week|

|Max dose|3.0 mg/day|2.4 mg/week|15 mg/week|

|Average result weight loss| ~8 % | ~15 % | ~22 % |

|Most common side effect|Nausea (~40%)|Nausea (~44%)|Nausea (~25%)|

|Interruption due to side effects| ~10 % | ~7 % | ~6 % |

The numbers speak in favor of the newer preparations in terms of pure weight loss, but Saxenda still has its place in the treatment arsenal. Patients who do not tolerate semaglutide — for example, due to severe nausea or unusual allergic reactions — can often handle liraglutide better thanks to the lower potency and daily dosing that provides more control over possible side effects. Saxenda also has the longest safety track: the drug has been used clinically since 2015, and long-term data from ten-year follow-ups provide a security that newer preparations cannot yet offer.
