NALTREXONE HCL  (NALTREXONE HYDROCHLORIDE):  This medication is used to prevent people who have been addicted to certain drugs (opiates) from taking them again. It is used as part of a complete treatment program for drug abuse (e.g., compliance monitoring, counseling, behavioral contract, lifestyle changes). This medication must not be used in people currently taking opiates, including methadone. Doing so can cause sudden withdrawal symptoms. Naltrexone belongs to a class of drugs known as opiate antagonists. It works in the brain to prevent opiate effects (e.g., feelings of well-being, pain relief). It also decreases the desire to take opiates. This medication is also used to treat alcohol abuse. It can help people drink less alcohol or stop drinking altogether. It also decreases the desire to drink alcohol when used with a treatment program that includes counseling, support, and lifestyle changes.   FDA Approval Date: 1998-05-08 (Sources: U.S. Centers for Medicare Services, FDA)

 2  Fibromyalgia Started at 3mg slept better and started to feel more energy and better mood. 4 weeks later I couldn't sleep, noticed headaches and nausea. Went down to 1.5mg taken in the morning and still big trouble sleeping. Don't feel like it's doing that much for pain so I am probably going to discontinue. F 53 60 days

 1  Nerve pain Headache, nausea, vomiting, feeling high (on 0.5 mg), exhaustion, facial edema and redness, 7 pound weight gain in 2 weeks, poor sleep (early awakenings), breakthrough period bleeding, extreme irritability, dark urine, constant epi gastric pain, burning diarrhea, extreme bloating (looked 7 mos pregnant). Patient groups are run by people who suppress any negatives about LDN. They claim that LDN has none of the side effects of full dose naltrexone and demand that any patient stating he/she has experienced side effects produce proof (in the form of a rigorous scientific study) that the side effects came from LDN. For this reason alone, large scale safety (if not safety and efficacy) studies need to be carried out by experienced and unbiased university clinical researchers on patient populations that specifically mirror those who are drawn to LDN as a potential treatment.

 1  Chronic pain, Cervical Dystonia The side effects have not subsided for me, in fact they have gotten worse. The vivid dreams of deceased relatives, terrible headaches that are not relieved with Tylenol or ibuprofen, and nape of neck pain have gotten worse, the hung over feeling that last two to three hours after waking, and now I am dealing with severe abdominal pain in my upper left side. Also, this weird noise and dizziness when I blink or move my eyes. The Dr that prescribed this med doesn't have any answers for me on how and when these symptoms will go away. Anyone else have the same experience with this med or advice for me, please reach out, I am still dealing with this today. Thank you F 44 45 days

 4  Alcohol use disorder Maybe a little sleepy not like fatigue though. I can not tell if it affects my exercise though. I seem to still feel good after. I had no desire to drink for the first 2 days. When I drink now I drink no more than 3 beers. I was drinking 6-8 beers a night. It did not work if I did not take it an hour before drinking. Now I take it at 6pm and it seems to work. I am really excited to finally have an option as I am unable to quit by myself. If I have alcohol in the house in earlier part of day I drink though. Now I make sure there is no alcohol and I have had success. I would recommend. M 42 2 weeks

 1  Rash If you have any sensitivity to drugs which interact with norepinephrine do not take this. I only took it 1 day and 3 days later I am so sick. Extreme dizziness, brain fog, blurred vision, cramps, extreme nausea, shakes, chills. It's one of the worst medications I've ever taken. I could not do my job almost immediately after taking it.

 1  Polycystic Ovarian Syndrome Candida overgrowth Severe candida overgrowth. I had no idea what was happening to me until I put two and two together and realized that this drug made my candida out of control. For people who say it gave them IBS--it may be candida. I finally researched enough to see that this can indeed assist in candida overgrowth. DO NOT RECOMMEND F 22 2 weeks

 5  Fibromyalgia Tiredness at 1st, but went away in a few weeks This is my miracle drug. I was taking tramadol before which helped, but I still had mild pain. Before I took anything my pain was so bad. Before I knew I had fibro I toughed out the pain for 3 years. I couldnt lift my arms past my waist and in order to roll over in bed I had to lift my arms slowly to roll over. I would leave 2 hours before work and stop every few minutes to rest. Note I live 10 to less than 15 min from work. Lifting a pencil was so painful. I decided enough is enough and saw many many doctors before I found 2 that helped me diagnose my fibro. And maybe frozen shoulder they said. I see a pain mgmt doctor now who prescribed me the low dose naltrexone. It's my miracle drug. It gave me my life back. I work as a pharmacy tech and other patients also agree that it's working for them. One said she was just starting it and didnt like the side effects. I told her to give it a a few more days and now she said she was glad she did. They milded down. I see patients who are on continuous use opioids and often wonder if this would work for them.. I hope the FDA is looking into this drug as possible approving it. At least making doctors more aware of it to try for their patients. Getting them off opiods.. I read it can also help with crohns, which I also have. I'm not sure on how it can help with that. My crohns is under control as of today. It would be neat if it helped with that. F 40 3 years

 5  Fibromyalgia Energy, spaciness, tired after meals I tried naltrexone at a low dose of 4.5 mg dose years ago, and it had no effect on my pain levels. But at a higher dose (I started with 24.5 mg and now take 50 mg) it is extraordinarily effective. I'm thrilled with this result, but I worry about the long-term effects, so I do not plan to take it indefinitely. The side effects - energy, a spacey feeling - I find pleasant. But this also makes me worry that perhaps this is just another painkiller, and that I'll build up a tolerance and be worse off when I try to wean myself off it. It's promoted as safer and non-addictive, but not enough is known about it yet for those claims to be trusted. It perplexes me that naltrexone is an opioid antagonist, but it feels slightly like an opioid to me. So I'm trilled to have relief from the pain, but I proceed with caution. F 58 3 months

 1  Fibromyalgia I got so sick after taking it. Nausea, shaking, anxiety, sweating. It was awful. And it always happened exactly ten hours after taking it. My doctor told me to stop it right away. No other doctors can prescribe it here in the county of 3.5 million people where I live. My rheumatologist wanted me to take it but could not write the prescription for some reason. Why not? It's all very suspicious, especially since proponents of it blame Big Pharma for it not being available to everyone for financial reasons. They also say that patient testimonials are all we need to prove it works. No, you need large double blind tests to prove it, not small groups of 12 people. That's how science works. Be wary. Research this drug. You'll probably stumble upon the people who have been barred from writing this prescription and non-physicans who write it hiding between the enthusiasm for the drug. I do hate to call it a cult. But if it was a safe drug with so many benefits, "Big Pharma" would be all over a new formulation. F 35 7 days

 3  Irritable bowel syndrome It helped with my IBS and sleep. But it made me lazy and unmotivated during the day. When I stopped taking it I found I slept very poorly. Prior to starting on it I slept fine. I went off it for 2 months but my sleep never returned to normal so I went back on it. M 55 5 months

 4  Mast Cell Activation Syndrome, CFS Nausea, diarrhea I have struggled with pain inflammation, sinus issues and general malaise due to chronic fatigue, and a host of other problems. Doctor felt my sinuses and trouble breathing was due to Mast Cell Activation Syndrome and put me on this. It has definitely helped my breathing but every morning I have had to deal with low grade nausea that lasts until the late afternoon. It gets worse if I increase the dose to 4.5mg. I've reduced the dose back down to 3mg but I might reduce it even further to 1.5 or stop all together if I can't get rid of the nausea as it's hard to go about my business feeling this way.

 5  Alcohol dependence Early side effects of dizziness and nausea, but that passes in 2 weeks. I was a heavy drinker from the time I was 20 or so until I was 29. got Naltrexone 50mg. If I wasn't at work or asleep I was drinking. As hard as it was, I stayed sober for 6 whole days before I started the medicine. From the moment I took the first pill, it. was. gone. I was no longer an alcoholic. They say that once a drunk always a drunk, I'm living proof that is false. I took Naltrexone for 6 months and never looked back. Naltrexone changed and saved my life.

 5  Alcohol First couple days I had nausea but went away. Then couldn't stretch enough but that passed also. A little sleepy for the first 5 days. I was drinking 8 to 10 beers everyday, for 2 days I had no cravings at all. I averaged out my drinking for 14 days and it is 3.9 drinks. 3 of those 14 I forgot to take it one hour before drinking which is the recommendation from the Sinclair Method. Works much better when I take it a hour before. I also watched a video from Ted Talks with Claudia Christian and it was awesome! Also, there is a book about the Sinclair Method called The Cure.

 4  osteoporosis, DDD, fibromyalgia None Had been experiencing increasing pain from osteoporosis, degenerative disc disease and fibromyalgia. A car wreck aggravated everything. This drug did help me a lot. Not to say I didn't have some aches and pains but not nearly as bad as before. Only problem is that occasionally I felt good enough to do heavy cleaning in my house and the next day had increased pain. I have learned to pace myself. F 65 30 days

 4  Ulcerative Colitis Taking from 3-4.5 mg per night before bed. This is called low dose naltrexone and is used for things like ulcerative colitis, cancer, and a lot of other stuff at this low dose. It helps your overall health but I came on here to warn people that is does have similar side effect to steroids in that it can make you enraged to a psycotic level where you want to beat the living ____ out of someone. Be aware of this and leave the room if you get in an argument with someone otherwise you literally will not care and will say a whole lot of _____ you would normally not say or care to say. I use a 50mg tablet and dissolve it in 50ml of distilled water in a tincture then drip 3-4.5ml of that after shaking it so it may not be exact all the time but I am too cheap and lazy to order more exact ways to measure it. You have to get it illegally if you want to use it for ulcerative colitis or find some expensive alternative doctor to prescribe it (safest idea), since my bastard GI refused to prescribe it to me for UC, all he would prescribe is steroid prednisone. I use the naltima brand or the nodict brand, don't sense any difference between them, both are naltrexone. M 46 3 years
