The load-loss drug Wegovy is now accessible in Australia.
Wegovy is run as a once-weekly injection and is authorized particularly for weight administration. It is supposed for use together with a reduced-energy food plan and elevated bodily exercise.
So how does Wegovy work and the way a lot weight are you able to anticipate to lose whereas taking it? And what are the potential dangers – and prices – for many who use it?
Let us take a look at what the science says.
What’s Wegovy?
Wegovy is a model title for the remedy semaglutide. Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1RA). This implies it makes your physique’s personal glucagon-like peptide-1 hormone, referred to as GLP-1 for brief, work higher.
Usually once you eat, the physique releases the GLP-1 hormone which helps sign to your mind that you’re full. Semaglutides improve this impact, resulting in a sense of fullness, even when you have not eaten.
One other function of GLP-1 is to stimulate the physique to provide extra insulin, a hormone which helps decrease the extent of glucose (sugar) within the blood. That is why semaglutides have been used for a number of years to deal with kind 2 diabetes.
How does Wegovy differ from Ozempic?
Like Wegovy, Ozempic is a semaglutide. The best way Wegovy and Ozempic work within the physique are basically the identical. They’re made by the identical pharmaceutical firm, Novo Nordisk.
However there are two variations:
1) They’re authorized for 2 totally different (however associated) causes.
In Australia (and the US), Ozempic is authorized to be used to enhance blood glucose ranges in adults with kind 2 diabetes. By managing blood glucose ranges successfully, the remedy goals to scale back the chance of main issues, equivalent to coronary heart illness.
Wegovy is authorized to be used alongside food plan and train for folks with a physique mass index (BMI) of 30 or larger, or 27 or larger however with different situations equivalent to hypertension.
Wegovy can be utilized in folks aged 12 years and older. Like Ozempic, Wegovy goals to scale back the chance of future well being issues, together with coronary heart illness.
2) They’re each injected however come in numerous strengths.
Ozempic is obtainable in pre-loaded single-dose pens with various dosages of 0.25 mg, 0.5 mg, 1 mg, or 2 mg per injection. The dose might be slowly elevated, as much as a most of two mg per week, if wanted.
Wegovy is obtainable in prefilled single-dose pens with doses of 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, or 2.4 mg. The therapy begins with a dose of 0.25 mg as soon as weekly for 4 weeks, after which the dose is progressively elevated till reaching a upkeep dose of two.4 mg weekly.
Whereas it is unknown what the affect of Wegovy’s introduction will probably be on Ozempic’s availability, Ozempic continues to be anticipated to be in low provide for the rest of 2024.
Is Wegovy efficient for weight reduction?
Given Wegovy is a semaglutide, there may be very robust proof it could possibly assist folks reduce weight and preserve this weight reduction.
A current examine discovered that over 4 years, individuals taking Wevovy as indicated skilled a median weight lack of 10.2 p.c physique weight and a discount in waist circumference of seven.7cm.
For many who cease taking the remedy, analyses have proven that about two-thirds of weight misplaced is regained.
What are the unintended effects of Wegovy?
The most typical unintended effects are nausea and vomiting.
Nevertheless, different severe unintended effects are additionally attainable due to the whole-of-body affect of the remedy. Thyroid tumours and most cancers have been detected as a threat in animal research, but are hardly ever seen in human scientific literature.
Within the four-year Wegovy trial, 16.6 p.c of individuals who obtained Wegovy (1,461 folks) skilled an antagonistic occasion that led to them completely discontinuing their use of the remedy. This was greater than the 8.2 p.c of individuals (718 folks) who obtained the placebo (with no lively ingredient).
Uncomfortable side effects included gastrointestinal problems (together with nausea and vomiting), which affected 10% of people that used Wegovy in comparison with 2 p.c of people that used the placebo.
Gallbladder-related problems occurred in 2.8 p.c of people that used Wegovy, and a pair of.3 p.c of people that obtained the placebo.
Lately, issues about suicidal ideas and behaviours have been raised, after a world evaluation reviewed greater than 36 million stories of antagonistic occasions from semaglutide (Ozempic or Wegovy) since 2000.
There have been 107 stories of suicidal ideas and self-harm amongst folks taking semaglutide, sadly together with six precise deaths. When folks stopped the remedy, 62.5 p.c discovered the ideas went away.
What we do not know is whether or not dose, weight reduction, or earlier psychological well being standing or use of antidepressants had a task to play.
Lastly, issues are rising concerning the unfavourable impact of semaglutides on our social and emotional reference to meals. Anecdotal and scientific proof suggests individuals who use semaglutides considerably scale back their day by day dietary consumption (as anticipated) by skipping meals and avoiding social events – not very satisfying for folks and their family members.
How can folks entry Wegovy?
Wegovy is obtainable for buy at pharmacists with a prescription from a health care provider.
However there’s a hefty price ticket. Wegovy is not at the moment backed by means of the Pharmaceutical Advantages Scheme in Australia, leaving sufferers to cowl the fee. The present value is estimated at round AU$460 per thirty days dose.
