The Second, Third, or Fourth Time Around With Phentermine

Check out the ultimate guide to phentermine weight loss pills!

Although phentermine is the most widely prescribed weight loss medication, something that those prescribed it will often encounter when they search on the Phentermine.com forum, is that many people return to taking it after having taken it in the past, sometimes several times.  This can lead to concern that phentermine is ineffective in the long term, but as we explain here, there are many factors to consider when taking phentermine, and recognizing these is the key to making sure that this is your more successful and final weight loss journey.

Returning to Phentermine Following a Break

For new phentermine users, it can be surprising that, amidst the success stories, there are many people who report returning to phentermine after their first, second or third attempt. However, that is not to say that their previous attempt or attempts were ‘failures’; one important thing to consider is that the majority of doctors will only prescribe phentermine for limited periods, often with breaks of at least one month in between periods of usage. Sometimes doctors, or the patients themselves, prefer that the break is longer, so that the patient is able to establish a healthy eating routine without reliance on phentermine. As this conversation from the phentermine forum shows here, returning to taking phentermine may not mean that the patient gains weight during their time away from taking phentermine, but rather that they give themselves time to adjust and assess how to proceed with the remainder of their weight loss journey. This second time on phentermine therefore comes with added insight into how to maintain their new weight or continue weight loss without phentermine, and how making lifestyle changes while taking it can help to ensure long term success following the end of their prescription.

Regaining the Weight

The same thread conversation does, however, includes several phentermine users who gained back some or all of the weight that they had lost with phentermine before returning to taking the medication, but as the entries show, this is intrinsically related to their expectations of phentermine and their attitude to weight loss while taking it. This post summarizes the point very well as the forum user talks about losing 50lbs with phentermine in six months, but that’s because this was simply due to not eating very much as a result of a suppressed appetite and not as a result of learning new healthier habits, she went on to gain back the weight she had lost when she stopped taking phentermine and her appetite came back. One key phrase she uses is that she ‘leaned on the pill’, which is to say she expected that phentermine would do all the hard work for her, which may lead to weight loss but very rarely leads to maintaining this loss in the long term.

Phentermine should be seen as a tool to kick-start weight loss, not as a ‘cure’; to successfully lose weight and keep it off with phentermine, it is crucial that you use your time on phentermine as an opportunity to learn healthier habits such as drinking more water, exercising, eating healthier foods and avoiding processed foods. Phentermine provides a decreased appetite and energy boost, making it easier for you to remain motivated and focused on weight loss success as you have more energy to concentrate on eating healthily and incorporating more exercise into your daily life. Then, with these new healthy habits established as part of your new lifestyle, it will be possible to continue without relying on phentermine.

How to Make This Time Your Last

If you’re someone who has taken phentermine in the past and gained weight following the end of your prescription, there are many crucial things to consider. Perhaps the most important is that your first, second or however many times before we’re not failures, but rather experiences to learn from. If you have successfully lost weight in the past then you absolutely can do it again, and the fact that you have since gained weight does not detract from this success. However, it’s imperative that you change your way of thinking. Many people embarking on a new healthy-eating plan are serial offenders, whether it’s with phentermine or with a new diet, and so it is understandable to have a “If this doesn’t work, nothing will” attitude when you’ve been there before. However, this kind of negative thinking can really harm your best intentions.

Many studies have shown that a person’s belief in success makes it far more likely that they will achieve it. So, have faith that this is the start of a whole new you, and never underestimate the power of positive thinking. The best way to achieve this success is to learn from the mistakes you may have made in the past, such as those explained by forum users in the posts above. Phentermine gives you the opportunity to pick up new healthy habits, so rather than relying on phentermine to do all the hard work for you, you need to embrace this opportunity to establish healthier routines such as exercising, drinking water and eating regular healthy meals. With these healthy routines in place, the transition to finishing your phentermine prescription will be much smoother, and long-term success will be within your reach.

Another point raised by the phentermine users in these posts from the Phentermine.com forum is that, often, their second time taking phentermine does not give them the same effects, whereby the energy boosting properties and appetite suppression they experienced the first time around are not as apparent this time. Although this can be frustrating, if you are also experiencing this, then a great way to help boost the effects of phentermine is to add Phen Caps to your new healthy lifestyle. Phen Caps are a weight loss supplement which suppress appetite and provide energy, just like phentermine, but as they contain different ingredients, they can be used to complement your phentermine prescription and help make this time even more successful for you.

So, the good news is, with some positive thinking and a new approach to making this time on phentermine a success, whether it’s your first or your fifth time, long term weight-loss success is within your reach! If you’ve tried phentermine before and are starting again, we’d love to hear from you, so please leave your comments below!

  1. Hello my name is nikkia I start taking them 3 years ago next week. .. I’ve lost 170 on them I look and feel so good thank u so much

  2. This is my second time doing Phentermine. The first time I just wanted to lose 25 pounds which I kept off for 3 years by exercising and eating healthy. December of 2013 I had a complete Hysterectomy and had to stay home for 6 weeks I then gained 22 pounds back fast. I am on Phentermine again hoping to lose the 22 pounds I had gained. Last time I had the capsules this time they gave me a tablet I asked the Doctor are these the same she said yes but to me they are not as strong as 3 years ago. I lost 5 pounds the first week and 2 the second which is good you don’t want to lose to fast. I see now you have Phen Caps do they work as good as Phentermine and does the same company as the prescription Phentermine make them? I watched the video on Phen Caps and the only thing I don’t agree on is she mentions Dr. Oz well all the products he shows on his show don’t work and those people sponsor his show thats why he endorses those products.

  3. This is my third time on Phentermine. The first time I was 24 and me and my friend (who was overweight) decided to try them as she was scared to take them alone. I lost 20 lbs in 3 months with no diet or exercise and she lost 60 lbs and we were just so impressed with these pills and our results. A couple of years later (26) I had a baby and I wanted to get the weight off without exercising or dieting, so I started taking Phentermine again and I must say it was nothing like the first time! My appetite was suppressed, but I was still hungry with really bad headaches and at night when I was coming off the pill I was so irritated, so I decided not to continue! Well I am now 41 and I just had a baby 10 months ago and I have gained so much weight during and after the pregnancy and I just didn\’t have the motivation to eat healthy or exercise due to me being so exhausted. I went to the doctor yesterday and my blood pressure is up (not to be concerned about just higher than usual) and I currently weigh 260 lbs!!! I have never been this big in my life and I literally cried after I got off the scale. Needless to say my doctor has put me back on Phentermine and has advised me that I must change my eating habits and exercise this time around because I am not as young as before and my metabolism is slow. With that being said, I took my first pill today and I felt wonderful!! I had energy again I even went walking for 15 mins (got to start somewhere) and 6 hrs later I\’m still not hungry. I do have a very bad case of dry mouth but that\’s more reason for me to drink water instead of my usual sodas. I really hope the pills work like they did when I was 24 because I am so unhealthy and unhappy right now and if I can get a jump start with these pills like before then I will definitely do my part. If the headaches come back I will discontinue use. I really want to be where I was when I was 24 which was 160 (before Phentermine) so I have 100 lbs to lose! Wish me luck and good luck to Bonnie I hope you lost the 22 lbs.!

  4. Hi What you wrote sounds exactly like my experience. I had alot of success and felt great while taking phentermine years ago, (the white and blue speckled ones) but now I have just started back and I am taking the 30 mg black Lancett 0957 pills and they are awful, I have no energy, stomach upset, nervous and jiterry they just make me feel completely different and not good like before. May I ask you which phentermine pill you are having the great results with now? Which manufacturer and what do they look like? Thanks so much and good luck with this time around! Kathy

  5. This is my 3rd time with Phentermine. The first time I lost 30 pounds, with no problem, no exercising and had to force myself to eat. I also had trouble sleeping. I was in my 30\’s. The 2nd time around I was 43 and not sure how the weight crept up on me but I went back on them and again I lost 25 pounds, but it was a little harder this time and took longer but it worked. I am now 49 and have been struggling with my weight gain for over a year. My lowest was 143 and my heaviest was 178. I have hit 175 now, I started 3rd go round last year, and had no luck whatsoever. I had the headaches, but no sleeplessness – I slept too much and had no energy, was moody and I did get down to 155 but gained it back so quickly. I get a yearly wellness check at work – nice perk – and well the results of the blood test showed my thyroid was not working, I took it to my GP and was diagnosed with hypothyroidism. I am on synthroid, and taking the 30mg phen (i always took 37) I have added working out,careful eating and well watching everything – I have been back on Phen for 3 weeks (working out for 7), and only have 4 pounds to show in my loss. It\’s frustrating that\’s for sure – working out 5 days a week, eating better and now have cut out sodas. It may be a slow haul but I\’m not giving up! I go back to the Dr in October and they said they may up the mg when i go back we will see how its going. I can tell you its hell getting older! 🙂 Other than that thyroid I am healthy and always have been very active. I am finally starting to feel normal again from taking the synthroid. So we will see what happens

    • Oh wow this is my story too!!!! How did you go? I feel as though the phen isn’t working anymore because I’ve only lost 3kg in 8 weeks!! (I’m not sure how many pounds that is?) I am 5ft 4 inches and weighed 81kg now I weigh 78kg

  6. I was prescribed Phentermine 37.5 mg at the end of 2010 and was on it for 5 mos. I lost 25 pds, going from 167 to 142 without much effort of diet and exercise. My heaviest was around 180 but got down to 167 before getting on the pill but I couldn\’t get any lower. It was fantastic; I was so happy and felt so free and comfortable in my own skin. I could shop anywhere and clothes looked good on me! I was able to hang onto my weight loss for a few years before it started creeping back up to the 160s. I live in Ohio and the law only allows you to be on the pill for 3 mos at a time with a 6 mo wait to get back on. I went to a new dr that does weight and age management that did thorough blood tests for thyroid (showed it was high but not over limit), hormones, food intolerance and a 24hr urine hormone test that showed my cortisol wasn’t clearing. I cut out the food that showed intolerant and he put me back on the pill along with thyroid meds that brought my levels down to 1.2, DHEA, Progesterone and a bunch of other supplements to try to get my cortisol under control. I had little results and my weight crept back up to 170s. We then tried the other diet pills on the market Contrave which had terrible side effects that I couldn’t tolerate and Qysmia that had little effect other than losing a few pds. 2.5 months ago I started acupuncture, diet changes, and exercising 5 days a week for an hr each and gained 7 pds bringing me back up to 175, 35 pd from my lowest on the pill! Im trying to read up on cortisol and making changes to lower it but I am at my wits end working hard with no results. I may try to get back on the pill for the fifth time to see what happens. Glad to know I am not alone in this battle!

    • When working out, did you try Interval training? Im also hypo. I started on Phentermine 4 months ago and have lost 32 pounds so far. I started out at 227 and now weigh 195. Im 65 years old and 5’1″. It’s awful because being hypothyroid makes it very difficult losing weight. I work out 4 days a week. I have a trainer 2 days a week. I ride the recumbent bike for 30 minutes, One minute fast, 20 seconds slow. It really made a difference, I had a trainer for 1.5 years before trying phentermine. I’m praying that once I get down my metabolism will reset and I can keep the weight off. I’m hopeful. I also have dinner before 4:40 PM. I eat nothing after 5:00.

  7. I have taken phentermine, probably, 5 times in the last 9 years. Each time it works, but each time comes with some stupid side effect. It never gave me energy or kept me up at night. When I got older and started school and gained some medical knowledge, I figured out that the reason I was always tired while taking the stuff is because my resting heart rate was about 140. I didn’t feel palpitations, so I had no clue until I took my vitals one day and put the puzzle pieces together. I was tired because my entire body was working overtime, especially my heart. The last round I took it (nearly 3 years ago), I was determined I would change my eating habits and workout. Well, it’s hard to work out when your heart rate shoots up to 220 with minimal activity. Finally I had an EKG one day that had some signs of old muscle injury ( which admittedly was probably non-specific) but scared the daylights out of me. I of course ballooned back up when I stopped taking it, and am at my heaviest now. But I refuse to take it again. My advice is to be careful on this medicine. It is not meant for long term use.

  8. I am restarting Phentermine for the 2nd time. I made some dumb choices and have been stress eating. I almost feel as if my hips are growing and so paranoid about weight gain because i hated myself when i was bigger. I made an appointment and will go in Friday and will start Phen Saturday morning again. This time on Phen though i will exercise as i lost weight too fast last time and had saggy skin. Has anyone ever taken more than 25mg of Toprimate? I am not sure if that quit working the last time as well.

  9. I was prescribed 50mg of topimate. He actually asked me would I like to up it again. No way I am still experiencing hair loss in wads. Seems every time I shower I have a shower full of hair! Moody & gassy. 😲

  10. I’ve been on phentramine for the past 3 days now and I can already tell a difference in my appetite ..when can I expect to start losing weight?

    • Hi Brittany,
      If you’re taking phenTRAmine as opposed to phentermine then we’re not sure about that product and success rates. However, with most weight loss supplements and medications then you should start to experience weight loss after a week or so if it is working as it should.

  11. I had taken phentermine back in 2013 and lost about 20 lbs. pretty much kept it off and only had been on it a month, the 20 lbs took about three months and stayed off! I just take it a month to get me back on track with eating habits and exercise. I recently gained it back and started taking it again 37.5 and I feel fantastic and finally not starving all the time! I would eat even when I was full before taking it. I use phentermine for only a month to get myself back on track. I also break it in half and take half after breakfast and other half later afternoon. Gives me enegery and curbs my appetite so I eat sensibly and have discipline. Stating weight was 150 and now 131. It helps me with fine tuning, losing the love handles and puffy belly.

  12. I\’m 63 and took phentermine over a 30 year time frame 10 times. I always had good results and minimal side affects until this last time. I began to have hard scary chest pains the almost made me double over. I had them for a couple of days and when they did not go away I went to the emergency room. I had stop taking the pills a week before the pains so I\’m not sure if the pills had anything to do with the pain I experienced. Of course, I\’ve began gaining the wait back and I\’m trying so hard to keep it off. I just don\’t want to undo what I almost lost my life trying to achieve. I might sound crazy but I think I want to try the pills again for about a week to get a handle on my eating. Fighting obesity is hard work, I just don\’t want die trying to get it done.

    • Hi!

      That sounds like it could definitely be a side-effect of taking phentermine. We strongly suggest consulting with your primary care physician and telling them all about that experience before embarking on the phentermine treatment again. Yes, fighting obesity is hard work, but not worth losing your life or permanently damaging your health over.

  13. If I stopped taking phentermine a month and a half ago can I start up again now? I lost 30 pounds being on it for six months and I’ve gained Almost all of it back.

    • Hi Emily! Many people can take phentermine again after a break, but it’s ultimately dependent on your individual case and doctor. So, we’d recommend asking your prescribing physician if he/she thinks it would be okay for you to try phentermine again. Best wishes!

  14. Hi was taking Duromine a few years ago with great success then stopped as I fell pregnant. Have started taking them again 6 months post baby but they are not working anymore. Im eating less but I’m not losing any weight. Any idea why this might be?

    • Hi T! Could it be that you’re eating too little now? It seems counter-intuitive, but it actually slows weight loss when you don’t eat enough calories because your body thinks it’s in starvation mode and tries to hold onto the extra fat for energy. Unless your doctor specifically told you differently, aim for at least 1200 calories per day. You may be interested in these blog posts about calories for weight loss and eating enough on phentermine. Best wishes!

  15. I just had a baby 3 months ago and stopped breastfeeding two weeks ago. I tried Phentermine for the second time and I feel nothing. No energy and not curbing my appetite. Could it be my hormones affecting the drug? First time I used it two years ago worked great. Lost 40lbs in 4 months and kept it off till the baby. I only need to lose 30lbs this time

    • Hi Amy! We’re actually not sure about this one, but it’s not out of the norm for people to experience a lack of effectiveness when they’re prescribed phentermine again. We’d recommend talking with your prescribing doctor about other medications and/or weight loss strategies. Best wishes!

  16. I started taking phentermine last year was on it for a few months and had no side effects lost 30 pounds. I had gained some back and wanted to go back on so I started last month. They recently upped my dosage to 37.5 since everything was fine and I wasn’t really seeing any results. I was also on 37.5 last year and had no side effects. The past two days i’ve had severe nausea, haven’t thrown up but i’m so nauseas wnd bloated that I don’t even want to eat. I started taking the 37.5 approximately 4 days ago. Is this a side effect that could occur? Or is it something else?

    • Hi J! Yes, unfortunately nausea and bloating are common side effects of phentermine. Still, if the nausea or bloating gets worse, bothers you or isn’t going away, make sure to get in-touch with your prescribing doctor. He or she can best assess what’s causing the problem and help you treat it. Hope you start feeling better soon!
