How long is MJ still good to use once opened?

Hi all,

I finished my first pen last week (4th dose) and thought I’d try to use the golden dose for this week. I read that the pen will work if using some force and I think I might have used a bit too much force as the whole thing broke!

I binned the pen in frustration and used 30clicks on the 5mg pen. I then ended up ordering some syringes and needles from UK Medi for future uses (if I don’t end up being sent the new model pen!)

I ordered the 5mg pen for my 2nd month but decided to stay on 2.5mg as I’m still losing weight and think I want to see how long I can push the 2.5mg for. If I were to stay on the lower dose, that means I have 8wks worth of jabs in a 5mg pen but they only recommend using a pen for 30days.

Have people used the same pen for 8 weeks and found it ok?

Thank you!

Mounjaro vs ozempic

I’m finally going to have the discussion with my GP about starting either mounjaro or ozempic. However, I’ve no idea about the difference, which works better etc. How did you all decide on Mounjaro?

Could you please give me some feedback on Mounjaro?

Thank you so much 😊

Dear god, the diarrhea

Folks, help. I am on Week 1 of MJ (2.5mg) and I am struggling with the side effects.

For the first 24 hours, I didn't really feel anything.

For the second 24 hours, I had waves of nausea and queasiness. Then for the last 24 hours, I have struggled with explosive diarrhea and burping. 🫠

It is so bad, that I needed to take the day off work - even though I work from home. I was up all night, going back and forth to the bathroom.

I think I made the mistake of eating regularly yesterday and had big meals with lots of protein. Today though, I have had toast and a banana, water with electrolytes and Imodium.

Nothing is working. 🫣 Please tell me what has helped you.

I am due to travel to Galway this weekend for a girls weekend and I am genuinely terrified that I won't make the journey without shitting myself. 🥲 #brutalreality

I bit the bullet

Put in for my first order of Mounjaro, via MyBMI. What pushed me over the edge is my realisation I have no photos of myself with my 18months old in the last 6 months as I’ve been avoiding having my photo taken. Which is actually pretty sad ! I’m doing this for her. I have been a long time lurker on this community but was putting if off due to us currently saving for a mortgage. But I need to do this for me looking forward to putting myself first now!

What am I doing wrong?

Updated to add: I was a little nervous of calorie counting as looking back on my eating over the last 20 years, my eating has been disordered and I was a bit worried this would be another unhealthy habit - that probably sounds mad but hopefully you all understand. I’m working out calories today, onwards!

I started Mounjaro 2.5mg on the 25th of April and have only lost 3 pounds. I decided I wouldn’t purposefully do a calorie deficit or tracking from the start as I was overwhelmed by the idea, having about 60 pounds to lose. My diet was shocking though and I haven’t had a takeaway in 2.5 weeks. This week I was in center parcs and walked 33k across the week, I drank a decent amount of water and didn’t have crisps, treats etc. I had omelettes for brekkie and half a bread roll for most lunches. I can see on my face that it’s thinned out and I can see it on my body but the scales have barely moved and I feel so defeated and demotivated.

445 days and 124lbs later. Goal 🥳

What a start to the week😂

This day last year I was 100lbs heavier, but already starting to feel excited about the future.

… and now to figure out maintenance 🤦🏻‍♂️😂

Hope everyone has as great a week as I feel like I’m going to ✌🏻

Sneak peek: Monj.ie is getting a (long overdue) refresher! 👀

I can't ever seem to stop working on a million things at once, but I'm really excited to FINALLY announce I’ve been working on a long overdue redesigned version of Monj.ie, and.... it’s nearly ready to go live!!!

A big thank you as well to everyone who’s supported Monj.ie through Buy Me A Coffee ☕💚
With the number of people who’ve told me they’ve saved a decent amount using the site, I've actually covered the hosting + domain costs for 2026, so....

So instead of letting that sit idle, I’ve put the extra back into improving the site and functionality.

✨ The new version brings in some of the most requested features:
• Filtering by region, delivery type, and service
• Sorting (including price low → high 👀)
• GBP → EUR auto conversion so you can compare like-for-like
• Clear “what’s included” labels (e.g. consult + prescription vs bring-your-own Rx)
• Shipping vs collection info surfaced properly (no more guessing or digging)
• Service notes and real-world context
• A much cleaner, easier-to-scan pricing table overall (especially on mobile)

Before I fully switch it over, I’d love a few people to test it this week and tell me what’s confusing, broken, or just mildly annoying.

If you commonly review pricing and would have a few minutes to spare for having a poke around and telling me where to go, er... giving me feedback, please send me a DM or modmail and I'll send you a link tomorrow! Please note it's not finished yet - but it's in a good enough shape to be able to test functionality.

Really appreciate everyone continuing to contribute, share updates and experiences 🙌

Bit of a (not done!) sneak peek below!! 👇

Delivery delays

Anyone else noticed the service is much slower since they have introduced this new delivery method.

I have always confirmed my order and pretty much had the delivery the next day. I try to time it for my work from home days so that I'm here for it. This time I paid everything Sunday night presuming it would be ready and picked up Monday to be delivered to me today. But since Sunday all my DPD tracking says we have been told that your epharm parcel will be dispatched shortly?

Last month it was delayed too but I put that down to the protests at the time.

5mg - no progress

Hi, third time posting and looking for advice/ reassurance of people who may have been in similar situations.

I have started 5mg last Thursday, second dose in two days. I’m feeling absolutely 0 effects. Despite eating in a calorie deficit my biggest issue is food noise and giving into it.

Feeling so frustrated. Not sure if I should just give up and am I just one of the non- responders. The annoying thing is Saxsenda worked so well for me and I know what it feels like to not have the food noise.

If anyone has had similar experience I would love to hear.

Titration Query - too much, too soon?

Hi everyone,

Firstly, I'm very appreciative that this forum exists. I've found it very helpful as I have started to learn about Mounjaro.

I went to my doctor last week and was prescribed Mounjaro. I, like a lot of other people, was anticipating pushback but my doctor was very open to prescribing a GLP1. To be honest, she was nearly too casual about it. I had read the book 'Weightless' as I explored treatment options for weight management and I'm so happy I did. It was from that that I realised that Mounjaro was probably more suited to me than Ozempic because I have arthritis and struggle with joint and mobility issues. I also have ADHD so managing food noise and the urge to use food as a stimulant are challenges.

However, when I said this to my doctor, they didn't really seem to be able to advise on what medication would work better for me. Their main point is that Ozempic is cheaper than Mounjaro - an important factor, yes, but not the only one. They also didn't advise me to get a DEXA scan done which I know from the book is important because it gives you a more realistic and holistic image of your body composition. If I just focus on BMI, I may miss out on the importance of understanding my muscle to fat ratio.

All of this is to say that I had some doubts about the degree to which my doctor is clued in. She prescribed me a 6 month prescription.

Month 1: 2.5mg
Month 2: 5mg
Month 3: 7.5mg
Months 4 - 6: 10mg

I understand that 2.5mg is the starting dose, but I have also read that it's recommended to stay on a dose for as long as possible if it is working. I'm concerned my doctor has ramped it up quite quickly that I won't get the full benefit of lower doses if I'm increasing the dose too quickly.

I'd love to understand if this is common or whether I should maybe consider speaking to my doctor and arrange more check-ins along the way. For now, I'm not expected to come back until I hit the 6 month mark.

How do I bring up wanting to take Mounjaro with my GP?

I am scared they will sideline me. I am 33 and I weigh 76kgs at 5’3. I have an obese BMI. My weight has exponentially increased after I’ve gotten my graves disease treatment. My metabolism has steadied but during hyper thyroid periods I would have constant appetite and that hasn’t gone away. I have constant craving and I can’t keep my weight down. I go to gym regularly but the food obsession is ruining my life

How should I approach the conversation with a GP? My old GP left so this will be a new one

Mounjaro NI yo ROI

Hey. Myself and my partner are both on Mounjaro. The last month we got it delieverd from Maghabebarry pharmacy in Northern Ireland. This month we have been told they cant deliver anymore. We tried several other chemists and are getting the same response including Corrys and McCartans. I am wondering if anyone knows of any northern Ireland chemists that still ship to the republic? Or if theres a website you can get the mounjaro on that is cheaper than the pharmacies in the republic? Thanks so much!

Delivery from My MBI

Hi all, first post! On my 2nd week of mounjaro and have lost 11lbs, so thrilled.After a lifetime of losing and gaining weight, this finally feels "easy" as the hunger or desire to eat/overeat is not there.

I got my 1st script from at my local chemist,but need to try somewhere cheaper.My main concern is when the box is delivered will it be visible who it is from?.I have not told family and I do not want them to see it.

Thanks all

Considering it

My GP recommended ozempic or mounjaro. She told me to do some research and come back to her, and if I wanted it she'd give me a script.

I had a question about one thing she mentioned. She said it gets rid of food noise. And that sounds great. To be able to stop my thoughts always circling food and snacks would be great. But I'm worried, because I don't want it to go away completely. I love to cook. I love the smell of a tomato sauce bubbling away on the hob, of a roast in the oven. I love to eat really good food. I don't want to lose any of that joy. Will I?

Sorry if that's a very stupid question.

I miss enjoying food!

I did four weeks at 2.5mg and then went up to 5mg. I took my second 5mg on Friday evening (48 hours ago)

I got engaged on Thursday so this weekend has been so enjoyable, went away for the weekend and lots of meeting friends and family for food and drinks. I find the first 48 hours after jab the worst symptom wise, with complete suppression and nausea etc.

I didn’t enjoy anything I ate all weekend, couldn’t finish any meal and wasn’t hungry for any of it. Had a couple of glasses of wine, was by no means drunk, but still ended up with me being sick and vomiting.

Today I was out for a few hours and had three drinks, hadn’t been able to eat since breakfast but had some pizza and was sick straight away again. I have been sick all evening throwing up everything that I ate and drank today.

I know my choices haven’t been the best, but I’m celebrating a really special time and it’s hard not enjoying anything I’m eating and feeling so crappy!

My in laws have organised a family meal for next Saturday to celebrate our engagement and I’m not sure what to do in term of my jab as I would really like to be able to enjoy the meal.

Just needed that rant 😅

Travelling abroad with mounjaro from Ireland

Hi all, I'm travelling to Italy on holiday in two weeks time and I'm wondering if anyone has any tips on how best to package the pen to keep it cool but within airport security regulations.

i plan to bring it in my hand luggage. It's really the keeping it cool that I'm struggling with.

Any suggestions or how did you travel with yours?

Many thanks

Hi, I've been reading through the posts here and feel like I have tried everything I've found.

I started mounjaro just over two weeks ago. I had little to no side effects apart from a little bit of constipation towards the end of the first week but the second dose sorted that out and I was going again as normal. However, towards the end of the second week, things started to slow down again. I added in a daily kiwi (skin on) and figured my third dose would get me going again anyways. Well I took the third dose on Wed and I'm still not going. I am easily getting 3L of fluids daily, plenty of fruit, I took a glass of prune juice yesterday and today and even added lactulose this evening. Still no joy and I'm starting to feel miserable now. What else can I do? What am I doing wrong? TIA

Edit to add: I'm getting a minimum of 7k steps per day
