phentermine-alcohol

Most of us like to relax with a cold beer or a glass of wine after a hectic week, but then we also know how alcohol isn’t great for our health. When you’re aiming to lose weight, alcohol is often best avoided due to the number of calories it contains and the effects it has on the body, but for those taking phentermine there are further risks to consider. Here we explain how alcohol hinders your best weight loss efforts and why it is inadvisable to mix phentermine and alcohol, with respect to both the success of your weight loss journey and to your health.

 How Alcohol Effects Weight Loss

The bottom line is, alcohol and weight loss really don’t mix. There are several ways in which alcohol negatively effects the chance of success on your weight loss journey. Firstly, alcohol contains many empty calories, meaning it is high in sugars which get converted to fat without providing the body with any nutrition. Secondly, alcohol decreases testosterone levels and causes fluid loss and tiredness, meaning exercise is more difficult and less effective. As a depressant it also suppresses the functions of the liver for as long as three days following the consumption of alcohol, meaning it limits your body’s ability to burn fat and build muscle by stopping the liver from processing food into energy. Lastly, alcohol leads to poor food choices as it activates hunger messages in the brain, leading to cravings for unhealthy foods high in saturated fat and salt.

The Interaction between Alcohol and Phentermine

For those taking phentermine to lose weight, as well as the effects of alcohol on weight loss, there is the additional reaction between phentermine and alcohol to consider, which comes with risks to health and potentially dangerous side effects. The problem with combining alcohol and phentermine arises from the fact that phentermine is a stimulant while alcohol is a depressant. Phentermine works as a weight loss medication because it directly affects the central nervous system by suppressing the parts of the brain responsible for appetite control, while other functions are stimulated to enhance energy and tolerance to intensive exercise. By contrast, alcohol suppresses the main functions of the central nervous system. The mechanisms of phentermine and alcohol are different, so simultaneous consumption of these can result in a negative drug interaction.

Warnings about drinking alcohol while taking phentermine explain that the combination can increase the risk of cardiovascular side effects, such as increased heart rate, chest pain or changes to blood pressure. You may also be more likely to experience symptoms such as dizziness, drowsiness, depression and difficulty concentrating. This thread from the Phentermine.com forum demonstrates some of the side effects that those taking phentermine have experienced, including jittery feelings, an inability to concentrate or interact in conversations, feeling on edge, and enhanced anger.

In addition to these negative side effects, alcohol also makes phentermine less effective, as one of the forum users mentioned in the link above. Alcohol activates hunger and greatly limits the effectiveness of the phentermine by reducing the appetite suppressing effects that phentermine has on the brain, while also decreasing the energy boost that phentermine supplies. Alcohol also effects the pH balance of the body, making it more acidic; phentermine has been shown to last longer in the body by as much as twice as long when the pH balance is more alkaline, which can be achieved by eating lots of fresh fruit and vegetables, while refraining from unhealthy acidifying foods and drinks like ice cream, butter, coffee and alcohol.

Advice on Alcohol and Phentermine

The most advisable approach would be to refrain from drinking alcohol while taking phentermine, or at least to limit the amount of alcohol you consume. Your doctor will explain to you what you should and shouldn’t do while taking phentermine, including your recommended maximum intake of alcohol. To ensure that you are more aware of how alcohol affects your body when you begin taking phentermine, you should aim to drink slower and to alternate alcoholic drinks with glasses of water to keep yourself hydrated and to give the alcohol time to enter your body so you can monitor how you feel. If you begin to feel unwell or experience symptoms such as those mentioned above, you should stop drinking alcohol immediately.

While it is true that some people experience no adverse side effects from mixing alcohol and phentermine, it is something that everyone should approach with caution, as when taking individual differences into account, this kind of drug interaction can be very dangerous for some people. Much of the success you will gain from your weight loss journey is related to knowing your body and acting in a way that you know is right for your health and wellbeing. This means avoiding or at least limiting your alcohol intake so as not to experience these negative side effects when mixing alcohol with phentermine, as well as in order to enjoy a healthier lifestyle in the long term.

  1. How do you tell someone that it’s making them crazy?

    • There’s no good way to tell your wife she’s crazy. You might want to consider calling her doctor and voicing your concerns. He will probably live if he tells her instead of you.

  2. Be honest that you are concerned this pill is changing their mood. Have things gotten better or worse ?

  3. Just tell them. Honesty is the best. But be nice about itm

  4. Hi,
    My doc just prescribed phentermine 37.5 for me for a month to assist with the 35pds I put on over last 8 mths. Healthy other than arthritis issues which I see Rheumatologist for. I joined a cardio work out program to go 2x week which I start Thurs. I am sometimes sensitive to meds so I’m careful, such as benadryl I’m very allergic to but can take over counter cold meds. Question is….starting this new med phentermine and one of the side effects is heart rate increase am I ok to take it and go do my cardio work out? Is it going to be to much? They do monitor my heart rate at the gym im going to during the hour work out. I really want this to work and can handle most side effects listed but don’t want any heart issues. Im 44 yr old woman who eats mostly healthy just getting older and can’t keep weight off like I use to. Goal is 30 lbs in 3 mths. Only taking this med for a month.
    Thanks!

    • Hi Laura,
      An increase in heart rate is a common side effect but nothing to worry about, and the majority of phentermine users do some kind of cardio while taking the medication. We would advise you to start the workout program but to be conscious of your heart rate and stop if at any point you feel discomfort or pain, especially in the chest.

  5. Dear Concerned Husband:
    OMG!!! I totally agree!!!! I have a very dear friend who has been taking it for over a year now and it is making her totally crazy!! She has these intense anger outbursts that are demonic!! I don’t even know who she is anymore. It’s so sad because I’ve known her for 30 years and now she’s become the spawn of Satan.
    The anger outbursts are more intense when she has a few alcoholic beverages while taking the phentermine!

  6. I can usually drink and I can drink, well I started taking these two medications about three weeks ago I lost seven pounds, however, we have gone out twice, I have had three drinks while we were out. The first night I passed out at the bar, he had to carry me home and into the cab, and the second night I was out like a light! I do not remember anything I only had three jack and cokes, and believe me I can usually put them down !! These drugs and drinking are very dangerous, I will not be drinking and taking these meds ever again !!!! Thank god I’m alive, I fell flat on my face in the bar, blacked out and that is not like me at all !! very scary!

    • This happened to me this weekend! I am down 25 lbs and I take the 37.5 pill in the AM. This weekend I had a few captain cokes and I totally blacked out. I don’t remember a thing, I woke up in the hospital. I will not ever drink again while on this mediation.

      • Hi Joanna,
        Thanks for sharing your experience with us. We try to err on the side of caution when advising our readers about mixing alcohol with phentermine, but we’re sorry to hear that you had such a strong reaction. We hope that our other readers bear this in mind and take precautions when mixing the two.

  7. I’ve just started Phentermine 30mg and it’s already amazing for my appetite suppression. The only issue I have is that I’m craving cigarettes and alcohol! I used to be a methamphetamine user so I think the Phentermine is giving my brain that same trigger. I feel completely fine after a few beers; I’m just worried the calories from the beer will hinder my weight loss. I’m not usually a big drinker anyway, but it’s been a few beers every night lately. I’m living off beer and steamed veg lol

    • It’s been a couple of months now. How are your results? I just got my prescription today and it’s for 30 mg. Also, I’m curious to see how I do if I have a couple of cocktails while taking them.

  8. Omg!!! I have been taking it for 2 days…it’s great and I’m not hungry but do try to put some healthy food in my body… I need to lose 50kg…back injury…all a bit of a nightmare… But I have to admit I do suffer anxiety… Depression and I’ve used alcohol for a very long time to self medicate …25 Years… From the generation of binge drinkers!!! I am realising… Slowly …2 days …and yes I’ve been drinking… That I’m not getting the buzz I’d usually get!!! So I need to get it out of my life…its very hard…but alcohol is the reason I gave the typically fat around the middle . I’m 47 on Monday and shit I need a wake up call…yes I’m a mess ha ha…constructive feedback only please 🙂

    • I can relate completely. Same age as well.
      Can you tell me if you are still doing this medicine. I’m thinking of trying it out and wanted to know how it’s going. Thanks

      Matt

  9. Janet – I hear you! You aren’t alone. I like a daily drink. Or two and while I lost the first week to 2, nothing since then. I know it’s a crutch, a habit, my signal to relax and that I really will do much better in many ways to eliminate it, but it’s harder than dieting. Going to give myself Friday & Saturday and see if I can’t gain some control during the week. I always felt one isn’t hurting. I have to think hard how I want to lose the weight, and I can go back to an occasional cocktail. I’m sabotaging myself. Good luck to you.

  10. So would it be really bad if I had a glass of wine? How long does phentermine stay in your system ?

    • Hi Ainka,
      It’s fine to have the odd glass of wine, although it’s important to bear in mind that alcohol does slow down the liver for several days, meaning your weight loss might stall as a result. Phentermine stays in your system for up to 72 hours but if you’re just having one glass of wine then there’s no need to stop taking phentermine. Just let a trusted friend know that you might have a different reaction to normal and remember to keep hydrated by drinking water at the same time.
      Sally, phentermine.

  11. I’ve been taking phentermine 37.5 for around a week and with the exception of the first day or two of feeling a tad jittery/more energized I feel like I haven’t experienced any side effects whatsoever and I was worried about taking it beforehand. I’m 27 years old, 6ft and 200lb – I just wanted to drop about 20 lbs or so. Anyway, things are going fine but I have a bachelor party trip coming up in a couple days and I haven’t drunk since being on phentermine. I’ve read what others have said about being careful taking phentermine when drinking. But this is my best friend and we will be drinking quite a bit (nothing crazy but more than normal obviously).

    We will arrive Thursday afternoon and come home Sunday morning.

    I haven’t missed a day since I started taking phentermine like 8 days ago or so. My plan is to take it tomorrow (Wednesday) and then not take another one until Monday when I get back home to get back on my regular schedule.

    If I stop taking it should I be okay on the alcohol front?

    Side note – for the past month prior to taking the phentermine I had been having chest pains/tighteness on my upper left side (not sure why) for about a month. After taking phentermine I haven’t really had chest issues in a week.

    Thanks for any responses.

    • Hi Jon,
      It’s probably too late to advise you to not take the phentermine today, but just so you are aware, phentermine can stay in the system for up to 72 hours so it could be a good idea for you to take it a little slower on the alcohol front on the first day (Thursday) and see how you feel. Let a more reliable friend know and ask him to keep an eye on you. Try to drink water throughout the day/night as well and remember to eat something filling before you start drinking heavily – dairy products like yogurt are also good for lining your stomach before drinking.
      Have fun!

      • Hey Sally, after I wrote that I seen where you said phentermine stays in your system 72 hours so I didn’t take it today and won’t be. Just want to be careful. Thursday (tomorrow night). Will be the first night of the trip where we go out. I’ll try and take it slow that night for sure.

        • Hi Jon,
          That’s great, it’s better to be on the safe side definitely. Hope you have a great weekend!
          Sally, phentermine.com

  12. Love the reviews. Just started my journey today with the pills. Craving a glass of red wine. Smoking cigarettes like crazy. I feel real jittery 2. What now? Hopefully my weight loss…good luck everyone.

  13. I’m afraid my experience of phen has ended abruptly. Palpitations, waking up sweating in middle of night and a crushing sensation in the middle of my chest like an air bubble you can’t get rid of with a burp. The first time this happened I drank 2 large glasses of wine. Stupid and Scary. Have also had an impending sense of doom and depression like nothing I’ve ever known. I am guessing I have a condition I wasn’t previously aware of. Off to docs to find out. Please be careful everyone. Even if this is nothing, the side effects have been so nasty I won’t be using phen to sort my weight out.

  14. I’m going on a family cruise in 6 days. Um not a heavy drinker but I plan on having a few frozen alcohol drinks. When should I stop taking phentermine to be able to enjoy my drinks without worrying?

    • Hi Dee,
      Phentermine can stay in your system for up to 72 hours, so if you want to be sure that there is no phentermine in your body then you should probably stop taking phentermine 2 or 3 days before you leave. Have fun on your cruise!
