Mirtazapine for Major Depressive Disorder "My experience with Remeron is short. It worked wonders for me, but I stopped it as it causes awful weight gain. 21 pounds in 4 weeks. I looked pregnant. It made me more depressed. I would just eat. It does something to your brain that makes you feel as though you are never full. At night, I would sneak food. I could not stop. I was at 30mg. I've heard 15 mg is worse for weight gain. Also, this drug is also given to elderly patients who are undergoing chemotherapy and also given to people with eating disorders (bulimia and anorexia). As I said, in one respect, it did wonders for me with anxiety and depression and stopped the voices in my head and helped me sleep. But I couldn't go through gaining any more weight."

For Post Traumatic Stress Disorder "I have been taking mirtazapine 15 mg since August 2022 for my PTSD and anxiety disorder. I was prescribed this after trying sertraline and venlafaxine, neither worked, and I felt like I was losing my mind. This medication has saved me in a way, I never thought I would say that about medication, as I used to be very much against it. But life gets hard, and sometimes we need help, even if it is from a tablet. The main side effect for me is my appetite and weight gain, but to be honest, it isn’t the end of the world, and as long as you’re eating healthy foods, it’s not much of an issue. I also didn’t take them for 2 weeks as I couldn’t pick up my prescription. I had the worst anxiety and panic attacks I have ever had in my life. I don’t know if this was a side effect, but it was horrendous. So please, don’t make the same mistake as me and suddenly stop taking them."

Mirtazapine for Depression "This medication was the magic bullet for me, anxiety-wise and depression-wise. I slept extremely well, and my anxiety plummeted. I would have definitely stayed on it if it weren't for the atrocious weight gain! I am normally 110 lbs or so, and within 1.5 months, I was up to 130 lbs! During this time, I wasn't eating much more than normal, and I was skateboarding, canoeing, and running, yet still putting on weight. I was the happiest, yet the fattest I had EVER been on this drug, so it was a love/hate relationship. I decided to go off of it because I couldn't tolerate the weight. It was a shame since it was extremely effective for me otherwise. Oh well."

Mirtazapine for Major Depressive Disorder "This medicine is a godsend. Being 100% honest, I didn't like it because of the vivid nightmares, but they do stop with continued usage. Don't give up too soon. The vivid nightmares stopped after my 5th day of taking this drug. Now, 2 weeks later, my nightmares are gone and I have normal dreams that don't involve death, violence, or carnage. I sleep well and awaken rested. Some days there is a little grogginess in the morning, but it wears off as you start moving. A cup of coffee helps as well. My appetite has increased, and several people complain of weight gain. You will gain too much weight if you stay sedentary. I started lifting weights and doing planks and push-ups. That keeps the weight gain at bay."

For Insomnia "When I first took Remeron, I was knocked out cold for about 18 hours, which was insane! I almost quit, but decided to give it a real chance, and I am very glad I did. After a couple of weeks, the initial negative impact diminished, and my sleep settled on about 8 to 9 hours per night. My sleep was restful, and the next day I was sometimes slightly groggy, but I was that way anyway due to the insomnia. Ten years later, I am still taking it, and I sleep about 7 to 8 hours on average. If I wake up, I fall right back to sleep. Since my worst depression is in the middle of the night, it keeps my mood stable. If I forget to take it, I almost inevitably wake up at 2 or 3 a.m. I am slim, and after some initial weight gain, I lost the weight and have not gained it back. (I am 51 years old, 5'7" and 123 lbs). Only the dissolvable tablets work for me. I take 30 mg tablets right before bed. I would recommend that you give it a good trial period (one month) before giving up."

Mirtazapine for Major Depressive Disorder "I have taken this med for over 2 years. I've been suffering from insomnia, anxiety, and depression my whole life. I found that nothing could help. Every night I tossed and turned, waking up every 2 hours. The first night I took this, like magic, I slept a whole night without waking up. And every night since then it has worked. However, BEWARE, it will make you binge eat. You have NO control over it. Studies say weight gain from this med only affects like 15% of people. Use look at the reviews on here and across the internet–it's more like 90%. I've always been skinny, and I put on 14 pounds within a month of starting it. I quit for a week, which made me extremely depressed and unable to sleep, but I immediately lost all the weight. But I was so depressed, it hurt, so I got back on it. That's why I give this a 7, it's a conundrum, it helps so much with insomnia/depression/anxiety, but it makes you FAT. Don't try this med unless you've tried ALL other SSRIs and sleep meds."

Mirtazapine for Major Depressive Disorder "I was taking this medication for six years, and it was life-changing. I was struggling to gain weight, I never had an appetite, and I was depressed, and no medication seemed to work, but Remeron was the only pill that worked for me. Unfortunately, I put on 40 pounds, and I have an almost overweight BMI, so I will have to stop this medication. This medication won't 'cure' your depression, but it's as if nothing seems like a big deal when you're on it, so therefore you feel less stressed and anxious."

For Insomnia "I was suffering from insomnia for at least 10 years. Dr. prescribed many other drugs, but nothing worked. In 2014, Dr. prescribed mirtazapine 15 mg. It worked. It gives me sound sleep of 7 to 8 hrs. Now, I am on 7.5 mg, and have been using this drug for more than 5 years with good results. The only side effect is some weight gain. But it is okay for me because I was underweight."

Mirtazapine for Major Depressive Disorder "No matter how much sleep I got, I was constantly tired. I could barely function during the day. And when I was functioning, I wanted to eat everything. In 2 months, I ended up gaining 15 lbs, which definitely did not help with the depression."

For Insomnia "Don't listen to the horror stories. This is a very good medication that significantly helps alleviate insomnia if all the natural remedies don't seem to work. Yes, you can come off of this medicine and sleep normally again if you taper very slowly and have a game plan: exercise, eat right, take natural calming agents like chamomile tea, banana, fish oil, magnesium glycinate, ashwagandha, GABA, and melatonin if needed. Get into meditation. I did all this, and I've been off this med for almost two weeks, no problem. I took 7.5 for a few months after deaths in the family caused severe insomnia and slowly tapered off. This med helped me get great sleep with no side effects. It does cause weight gain if you don't exercise or eat lots of carbs, that's the only thing to watch out for."

Mirtazapine for Depression "I am using Remeron to help with nausea, depression, and anxiety as I taper off 1 mg of Klonopin after several years of using that drug. It was hard in the beginning; I had headaches and crushing fatigue for weeks. Now, I feel this drug has been a godsend; it helps with all and ensures that I sleep well most nights. This is my third attempt to get off of Klonopin and I have never been able to reduce my dosage so much. I do notice that my weight is now creeping up, so I need to watch that more carefully, but that side effect is one I will have to tackle as I will not give up my Remeron."

For Anxiety "I must say, mirtazapine was extremely helpful for my anxiety and depression, along with taking fluvoxamine for anxiety, depression, and OCD. A lot of the physical symptoms of anxiety as well as mental symptoms have diminished. Concentration has also improved. Although the weight gain from increased appetite and the sluggish feeling in the morning have become problematic. I have my mind set on discontinuing."

For Major Depressive Disorder "I've had major depression mostly every day for the last 2 years, and this medication is a lifesaver. After being on mostly every SSRI and on several different dosages, I never got complete relief from them. They helped to give me a slightly better mood on most days, but the depression was always there. After doing a lot of research, I told my psychiatrist I wanted to try mirtazapine. After roughly two and a half weeks on 30 mg (15 mg didn't help), I've never felt better. It also took away most of the night sweats that I was getting from SSRIs. I've read some people complaining about weight gain as a side effect, I would advise not to worry about weight gain if you actually have major depression. Once the depression lifts, you will be able to eat healthy."

For Obsessive Compulsive Disorder "I've been taking mirtazapine 30 mg for about four years. It has been effective for me in managing OCD symptoms-has enabled me to put things in perspective much better. Positive help with sleeping. Weight gain has been a challenge, but I've managed fairly well using exercise and limiting refined carbs."

For Insomnia "Remeron (mirtazapine) truly saved my life. I was ready to give up after trying 32 meds prior over 4 years. The catch in my experience is the less you take, the better. While I was told by doctors that the more you take, the less tired it makes you- I disagree. 7.5 is the smallest instant size, but I personally cut it down to 5. I can tell a huge difference. Also, it has a long history of making people want to eat compulsively, in which you gain weight- the med itself does not make you gain weight. Again, the less med you take, the less the compulsive eating side effects. Mentally, I just feel like me. I’m calmer about things and feel more capable of doing things, and it’s hugely helped with my movement disorder. The difference between this and Prozac or Zoloft is those two made me impatient and always had to be productive, so if for some reason I wasn’t able to be productive, I many days thought I should be productive and end my life. So mirtazapine has been a blessing."

Mirtazapine for Major Depressive Disorder "Gained 20+ pounds in a month on Remeron. I work out every day and always maintain a calorie deficit but still excessively gained weight. I took a DNA test, and it turns out I’m not compatible with this medication and experience significant symptoms. I would suggest to everyone to get a DNA test to see which medications will or will not work for you."

For Anxiety "Been on this for over 3 years now, and it's been good for me. I take 30 mg at night, and I sleep much better, and my anxiety is a lot lower. I used to have terrible panic attacks in public, so bad that I sometimes had to leave the store halfway through grocery shopping. So my doctor put me on this, and it's stopped the panic attacks in public places. I'm 36 now, and I wish I had found it sooner as I've had debilitating anxiety my whole life, but being a guy, I thought I would tough it out. In the end, it got too much, so I look to the future now, and so far so good on this medication. I actually live a normal life now, and I'm a more productive person. Only side effects have been a bit of weight gain and grogginess when I first wake up, but these are much better than the train wreck I was before taking this med."

For Depression "I've been taking 15 mg for a year and 8 months. Right away I felt better because I slept right through anger and woke up rested. Previously I took 40 mg of citalopram, and I still suffered bad episodes of depression and delusions. Since taking mirtazapine, I've had much longer periods of productivity, much calmer, less intense periods of sadness and distorted thinking. I stopped the citalopram about 7 months ago, so I'm very happy with it. The only drawback is that I went up at least a dress size, and I can't shift the weight, even though I'm healthier than ever and don't drink."

For Anxiety "As someone who was previously fearful of ever taking antidepressants, Mirtazapine has exceeded my expectations. Due to an unexpected life event, I became really depressed and anxious. This led to me going up to 4 days without sleep, and I was constantly in an anxious rut, which at one point made me suicidal. After 8 months, I finally resigned to taking Mirtazapine, which was prescribed by my GP (I take 7.5 mg at night). It has improved my sleep significantly and helped me get out of the anxious rut, and I now feel like my normal self. I have put on some weight, but to me, this side effect outweighs the state I was in before. Sometimes you have to weigh the benefits of a drug against the side effects. I would rather be a little larger and happier than anxious/depressed. If you are worried about taking Mirtazapine, there is no harm in trying it, if it doesn't work for you, you can always come off it. However, I would say at least try it for one month before giving up. Highly recommend!!"

Mirtazapine for Depression "Great medication, worked like magic for me. However, the major side effect that makes me stop it is the weight gain aspect. It makes me eat all the time and have cravings for sugar all day long. I have been on and off Remeron for the last 5 years, and the only reason that I am off it is the weight gain. I have tried many medications, but nothing worked for me. Remeron is the only antidepressant that gives me back my life."

For Anxiety "I have been on mirtazapine for four years. It saved my life. I fall asleep within thirty minutes of taking the medication. I had anxiety with agoraphobia for five years. I can come and go as I please now. I am not able to lose weight, and I do have an appetite all the time it seems. Give yourself time to get used to the medication, and make sure you are taking enough of it. I had to take 60 mg at one time, I am now down to 45. Please do not drink alcohol, it will reverse the effects of the anti-anxiety, and alcohol is just not good for anxiety or depression ever. Good luck!"

For Anxiety "I’ve been on mirtazapine 15 mg for almost 2 years for anxiety linked to menopause (and relationship worries) and have been taking it nightly to help mainly with sleep. Excellent for sleep as I was struggling massively before starting this, although I do tend to feel a bit tired during the day, particularly at weekends. I’m a teacher, so tiredness during the weekdays is usually negated by the demands of my job! As I’m naturally thin, I haven’t noticed much in the way of weight gain apart from normal middle-age tummy increases. I think that this is a great medication for use to support sleep issues and has gotten rid of the awful tummy butterflies I used to experience. I recently decided to reduce down to 7.5 mg, but anxiety began to creep in again, so I went back to 15 mg. If I have to take it long-term, so be it as it’s worth it. One negative is dreadful dry mouth first thing in the morning, as well as a bad taste, but it soon disappears."

For Major Depressive Disorder "I wanted to share my experience because I have been an avid review reader and often only negative experiences are shared. I tried Zoloft, Prozac, Wellbutrin, and Lamictal, and the side effects from all of these were too much for me. Remeron helps me sleep and gives me a feeling of general wellness and an ability to cope. It takes away that crushing depression that tells you you aren’t good enough and doesn’t allow you to get out of bed. The big story on this drug is about the weight, and I want to share with you that I may be a pound or two heavier with this drug than without it, but this drug actually helps me eat less. I used to feel hungry all the time and wake up at night from hunger, but now I can sleep through. Take the lowest dose you can if you are worried about this side effect and know that not all people gain weight on this drug."

Mirtazapine for Major Depressive Disorder "I have suffered from major depression for the past 20 years, which caused severe insomnia. Remeron has been a lifesaver. I have been able to sleep, but it causes weight gain. My doctor decreased it from 45 mg to 30 mg. There is no major difference between the dosages. I will be following a diet suggested by my dietician to lose 7 pounds gained from the meds."
