Wegovy 2.4mg vs 7.2mg: What's the difference and which is right for you?

Wegovy is a popular weight loss drug containing the active ingredient semaglutide. Up until now, it was available up to a maximum dose of 2.4mg, administered once-weekly.

Following regulatory approval in January 2026, a higher 7.2mg dose has been launched, targeting those individuals who could benefit from greater weight loss.

The new dose is available from Quick Meds, where GPhC-registered clinicians are on hand to help with your treatment needs.

Wegovy doses explained

Available in five dose strengths, patients start at the initiation dose of 0.25mg, administered once-weekly. This dose is then increased through 0.5mg, 1mg, 1.7mg and 2.4mg.

Doses are increased no sooner than every 4 weeks to allow the body to get used to the increased dose each time. Some patients find they do not need to increase as they have found a balance of weight loss against favourable tolerability.

Others need to continue to increase to benefit from greater appetite suppression, often reaching the maximum dose of 2.4mg.

At the maximum dose, if weight loss progress stalls, there's no room to go - until now. The new 7.2mg dose has been formulated specifically for those who could benefit from further weight loss and have tolerated treatment well.

Why the 7.2mg Wegovy dose exists

Unlike with other doses, the new 7.2mg dose is approved specifically for use in weight management and not for type-2 diabetes.

The new 7.2mg dose is for patients currently on 2.4mg, who are no longer losing weight, having reached a plateau. It provides another dose option to people who have responded well to Wegovy but need a boost.

Before increasing, it's important to consider the impact of lifestyle changes. Without sustainable changes to diet or incorporating increased exercise, even at the 7.2mg dose, Wegovy may not work.

Which dose is more effective?

Both the 2.4mg and 7.2mg Wegovy doses are effective for weight loss, but 7.2mg leads to greater average weight loss.

In a clinical trial comparing both doses, patients showed an average loss of:

• 15.6% at the 2.4mg dose

• 18.7% at the 7.2mg dose

• 3.9% on placebo

Individuals taking 7.2mg were also more likely than those on a 2.4mg dose to lose up to 25% of their starting body weight.

However, it’s also important to know that people taking 7.2mg may have an increased risk of side effects, although these are generally mild.

Who should stay on 2.4mg?

Those who are actively losing weight on the 2.4mg dose, do not need to increase. An increased dose does not mean quicker weight loss though may increase the risk of side effects.

Additionally, those who are more likely to experience side effects upon a dose increase are recommended to maintain at the lower doses for longer.

Side effects differences

As with all medications, Wegovy can cause side effects though not everyone gets them. These are most common upon initiation and with dose increases. Some patients report experiencing side effects more often on higher doses, but is this true of the 7.2mg dose?

The most common side effects include:

• Headaches

• Nausea and vomiting (being sick)

• Diarrhoea or constipation

• Stomach pain

• Fatigue

Less common side effects include:

• Dizziness

• Pins and needles

• Taste changes

• Stomach inflammation

• Acid reflux

• Burping

• Bloating

• Gallstones

• Injection site reactions

More serious side effects are much rarer and include:

• Low blood sugar

• Pancreatitis

• Low blood pressure

• Increased heart rate

• Kidney/bladder stones

Rarely, individuals can experience a severe allergic reaction, requiring immediate medical attention.

The patient information leaflet contains a comprehensive list of side effects.

The 7.2mg dose carries a slightly higher risk of side effects, occurring in 70.8% of patients compared to 61.2% in those taking 2.4mg.

How to take each dose

The original five doses, 0.25mg to 2.4mg exist as a FlexTouch pen, with each device containing four doses. Patients attach a new needle each week, dial a full dose and inject into their chosen injection site.

When the 7.2mg dose was initially approved in January 2026, the only way to administer it was to take three doses of 2.4mg in one sitting, using the existing 2.4mg device.

Since April 2026, a new single-dose device has been launched. A 7.2mg pack contains four pens, each containing a single dose. The needle is pre-attached and there is no dialling involved.

To inject a dose from the new device:

• Remove the cap

• Firmly press the pen against your injection site - this starts medication flow

• The needle is enclosed in the pen, you will not be able to see this

• The dose window slowly fills up with a yellow bar - once the yellow bar stops moving, your dose is complete

• Remove the pen - this will automatically cover the needle

• Replace the cap and dispose appropriately.

With the new device, it's important to firmly inject to activate medication flow. Additionally, ensure to not let go too early - if the pen is removed before the dose is complete, the needle will retract and you will not be able to inject the remainder.

Switching doses

It’s easy to switch between the doses as both contain the same medication. Be sure to speak to your provider for advice on switching.

Remember, you cannot start at the 7.2mg dose. The treatment is designed in a way where it must be started at the initiation dose and slowly increased - to allow the body to get used to treatment.
