<\/p>\nMounjaro users will soon be getting less of the drug for their money, manufacturer Eli Lilly confirmed today.<\/p>\n
The pre-filled injection pens are currently 3ml in size and designed to deliver a fixed amount of the drug once a week, typically over four weeks.\u00a0<\/p>\n
But this leaves a small amount of medication remaining in the pen after the final injection.<\/p>\n
In a cost-cutting measure dubbed the ‘golden dose’, some users draw out this additional liquid with a syringe and needle and use it for an additional jab.\u00a0<\/p>\n
The move today to slash the pen’s size, however, will prevent users from salvaging any spare medication slashing their chance of getting a fifth dose from the pen.\u00a0<\/p>\n
Mounjaro patients today took to social media sharing their frustration at Eli Lilly’s decision, branding it ‘another kick in the teeth’.\u00a0<\/p>\n
But health chiefs have also repeatedly urged patients against trying the hack, warning they could both physically injure themselves when trying to remove the fifth dose from the pen and risk infection.<\/p>\n
It comes as Eli Lilly\u00a0announced last month that wholesale prices of Mounjaro would more than double from September 1\u2014with the highest dose rising from \u00a3122 to \u00a3330 a month.<\/p>\n
<\/p>\n
There is a hidden extra dose in your weight loss jabs that could save you hundreds of pounds, users say \u2014 but doctors have warned of major risks<\/p>\n

<\/p>\n
The above image shows there is still liquid left over in the pen after the prescribed four doses \u2014 which many say is enough for a fifth<\/p>\n
Mid-range doses, such as the 5mg pen, were also set to jump from about \u00a392 to \u00a3180.\u00a0<\/p>\n
The announcement, however, still sparked ‘Covid-like panic buying’ with users boasting online of buying months worth of injection pens, to avoid having to pay the new price.<\/p>\n
Slimmers also took to social media to share tips on how to ‘golden dose’, in an attempt to make the pens last longer on their new price.\u00a0<\/p>\n
An Eli Lilly spokesperson told the Daily Mail today: ‘A modified KwikPen will be made available globally.\u00a0<\/p>\n
‘While the modified KwikPen has been approved in the UK, the timelines for availability are yet to be determined.\u00a0<\/p>\n
‘The initial Mounjaro KwikPen and the modi\ufb01ed Mounjaro KwikPen both contain the volume of solution necessary for priming before each injection and the delivery of four doses (one dose given weekly).\u00a0<\/p>\n
‘The KwikPen has been modified to reduce the amount of leftover medicine that remains in the KwikPen after four doses have been administered.’\u00a0<\/p>\n
Each Mounjaro pen contains 3ml of liquid, and each dose uses 0.6ml\u2014just enough for four, accurate, pre\u2013measured doses of Mounjaro.\u00a0<\/p>\n

By getting five doses out of each pen, regular users could save around \u00a3615 a year.<\/p>\n
Currently Pharmacy2U, the UK’s largest online pharmacy, has the strongest Mounjaro pen\u201415mg\u2014listed at \u00a3314, a huge leap from its previous price of \u00a3180.\u00a0<\/p>\n
Furious users today labelled Eli Lilly’s decision a ‘kick in the teeth’ and claimed they would still try to ‘golden dose’.<\/p>\n
In one Reddit forum, a user wrote:\u00a0‘Wow. This company are truly the gift that keeps on giving.’\u00a0\u00a0<\/p>\n
Another said: ‘I think they’ll phase the release so it will be a random chance whether you get the old pen or the new one which will Indirectly make stock piling risky.’\u00a0<\/p>\n
Meanwhile one user said it wouldn’t stop them from trying to extract whatever was left over.\u00a0<\/p>\n
‘Maybe half a dose left over so combining two pens with leftover for a full dose. The new golden 9th,’ they said.<\/p>\n
Similar to microdosing, which sees users try and inject a smaller than normal Mounjaro dose, health chiefs have also repeatedly urged patients against trying the ‘golden dose’ hack.\u00a0<\/p>\n

Dr Alison Cave, chief safety officer of the MHRA, said: ‘People should follow the dosing directions provided by their healthcare provider when prescribed weight\u2013loss medicines and use as directed in the patient information leaflet.<\/p>\n
‘Medicines are approved according to strict dosage guidelines.\u00a0<\/p>\n
‘Failure to adhere with these guidelines, such as tampering with pre\u2013dosed injection pens, could harm your health or cause personal injury.’<\/p>\n
Professor Penny Ward, a pharmaceutical expert at King’s College London, also told the Daily Mail:\u00a0‘People are reading these tips on online forums and being tempted to use them to save money.\u00a0<\/p>\n
‘But they’re risking serious side effects from overdosing by doing this \u2014 as well as the potential to develop a life-threatening infection. It’s not a good idea at all.’\u00a0\u00a0<\/p>\n
Under official guidelines, only patients who have a body mass index (BMI) of over 35 and at least one weight-related health problem like high blood pressure, or those who have a BMI of 30 to 34.9 and meet the criteria for referral to a specialist weight management service, should be prescribed weight-loss jabs.<\/p>\n
It comes as a damning analysis last week<\/a> revealed thousands of people are missing out on Mounjaro on the NHS because of a ‘postcode lottery’ of NHS<\/a> provision.\u00a0<\/p>\n Last year, health chiefs announced millions of obese patients would receive Mounjaro\u2014which helps slimmers shed up to a fifth of their bodyweight\u2014on the health service over a phased 12 year rollout.\u00a0<\/p>\n But since the rollout began in June, less than half of the commissioning bodies in England have even started prescribing the drug, analysis by the British Medical Journal found.<\/p>\n Weight-related illness costs the economy \u00a374billion a year, with people who are overweight at increased risk of heart disease, cancer and type 2 diabetes.<\/p>\n Two in three Britons are classed as overweight or obese and NHS figures show people now weigh about a stone more than 30 years ago.<\/p>\n","protected":false},"excerpt":{"rendered":"Mounjaro users will soon be getting less of the drug for their money, manufacturer Eli Lilly confirmed today.…\n","protected":false},"author":2,"featured_media":125219,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[97,59,102,56,54,55],"class_list":{"0":"post-125218","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-health","8":"tag-dailymail","9":"tag-gb","10":"tag-health","11":"tag-uk","12":"tag-united-kingdom","13":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/125218","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=125218"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/125218\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/125219"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=125218"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=125218"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=125218"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
