6-MP (also called 6-mercaptopurine or its brand name Purinethol) is a relatively common immunosupressive medication. Like most ulcerative colitis medications, you need to have a prescription and guidance from your treating physician to use this medication.
People using 6-MP may have a harder time with fighting off infection.
There are many documented side effects (as is the case with many medications) and some of these may include: vomiting, loss of appetite, skin rashes, dark urine. There is also a chance that 6MP may be toxic to bone marrow. More details about the medication and its possible side effects can be found on wikipedia’s 6MP page – here.

6MP is like a double edged sword. In my last colonoscopy exam in 2013, the ulcers have somewhat quarantined itself in batches and not as spread out as in 2012 shortly before being put on 6MP. I don't have the daily bleeding and diarrhea as before but when it does happen; it happens in droves. The bad side: I got Shingles in my first month of being on 6MP in 2012, the constant fatigue was the same as having Colitis; in 2013, I had bouts of occasional nausea but for one year, things were slowly becoming livable. In 2014, around the winter, I got Bronchitis following my carpal tunnel surgery which required 2 weeks of I.V. therapy (a steroid) then a week later a really bad case of nausea putting me on Zofran tablets daily along with it in liquid form in an I.V. I haven't been as nauseous like that since I started taking Turmeric as a tea and having ginger in my diet daily. This year, I got Bronchitis once again but not in the same severity as last year since I caught it in time. In a few weeks, I will be taking another colonoscopy to see how things are. I am also on Delzicol.
No good for me!
I feel for you all, I've had a bad flare up for 13 months this time. I'm on asacol oral and foam enemas, prednisone for 6 months, which is awful and azatheprine then I was so ill after a week so they took me off aza and put me on Mercaptopurine, I was good for one week and again seriously ill which started with the sorest throat I've ever experienced and then things just got worse, bloods went all over the place and in the end they took me off it to recover and then they'd like me to start again but when I read all the problems associated with this chemotherapy drug I've decided I'm done, I dot. Know if it's wise, but I stopped it all steroids and Mercaptopurine. I'm trying with a pure form of aloe Vera, diet and general healthy choice. I can't be no worse as they haven't got the UC under control for 13 months even with the steroids. My doctor is very understanding I just hpe the specialist will be when I see him but he didn't have to live with all the side effects from these drugs! I don't feel to bad and it's been 10 days. I'm in for another colonoscopy this Friday, which is to soon to see if my way is working but I do feel better for taking the control back, which works for me and feels good seeing the last 20 yrs it's all controlled me.
I have had UC since 1984. For the majority of that time, I was on prednisone which did not always worked for me. I switched doctors in 2001 and he got me off the prednisone using 6MP (100mg/day) and Colazal (750mg 3x/day). I have been symptom free in in remission since 2001. I had the 6MP dropped to 75mg/day. a couple of years ago and have been fine.
just got diagnosed with UC in June have been on 6-mp for two months and it has not worked. using only 50mg at first then he moved me up to 75mg and my liver went off the wall and that was only in two weeks so back to 50 and not doing so well, not sure what the next step is going to be...
I was diagnosed with UC in 2010. Ended up on prednisone for 9 months which was horrible. Started on 6mp in 2011 and had to go up to 150 mg for it to work. I am currently on 6mp 125mg with lialda and have only had one mild flare which was recently. I have had very few side effects, and so far 6mp has been great for me.
Took it for two weeks and ended up in the hospital with pneumonia. It came on fast without a cough or even a sniffle. Severe chest pains and difficulty breathing, my Dr sent me to the ER. No more of that for me. Suppressing the immune system is not a good idea
6MP; so far so good
I was diagnosed with UC in August of 2012... I was first put on Lialda which worked for exactly 2 weeks... Then they switched me over to 6MP... Yes, when I first read about this medication, I was a little concerned... But I was also desperate for my life back and so decided to give it a try... It's not disappointed me... I was prepared for the hair loss, and nausea, etc... After almost 2 years, I've had none of that... Well, I take that back... Before I figured out that you need to eat before you take the med, I did experience some very light nausea... But after a few days I figured out to eat, THEN take the pill and that was the last time I experienced it... So my experience has been positive...
6MP huge help
I was diagnosed with UC 14.5 years ago. Flare ups were constant. Prednisone was always prescribed. I was on Salazapyrin which didn't seem to help at all. My last flare up was pretty bad. On cortisone for about 6 months. My specialist had been trying to get me to take purinethol for a while but I was too scared but after the 6 months on cortisone I thought I should give it a try. That was 7 years ago and I have only had one very very mild flare up since. A couple of days of cortisone suppository and it was gone. Purinethol has made a huge difference in my life. I only take 50 mg a day and the results of my last colonoscopy and every other colonoscopy was great. In remission. The only side effects I have are mild hair loss and a permanent rash on the back of my neck which resembles a birth mark. My specialist was talking about taking me off the medication but we are a bit worried that it might come back with a vengeance. It's known to happen. I don't want to risk it. I get a bit scared of the possibility of cancer but I am only on 50mg so I figure it's worth the risk. I am going to ask my doctor if I could go down to 25mg. My immune system seems to be fine. I don't get sick very often at all. My blood test are always great. IBS on the other hand is dreadful. I deal with that every day. I honestly don't know what's worse sometimes.
Seems to be working, but my liver ain't happy
I was diagnosed with UC in Jan 2013. Allergic to sulfa drugs, so I was on prednisone for 5 months and Lialda. Doc added 6MP in May, and I started tapering off the prednisone, which caused me to lose about half of the hair on my head but grow a lot of facial hair (thank goodness I'm a natural blonde!) I am taking a 50 mg dose of 6MP, which is low for my weight, but my liver enzymes are elevated and I am B12 deficient, but not anemic. Not sure what that means, but I have an appointment with a hematologist and will probably start getting B12 shots because I am not absorbing the B-12 in pill-form. My doc does not think the 6MP is causing the high liver enzymes (they were elevated before I started the 6MP), but she is running more tests (bloodwork). At first, I did not think I had any side effects from the 6MP, but I have noticed a general "ache-iness." I chalked that up to being 45 and arthritic (my dad has pretty severe osteo-arthritis, and my mother had rheumatoid arthritis), but as I read more testimonials, now I am wondering if the 6MP is causing me to feel like an Old Lady. It's not incapacitating--once I get up and start moving around, I'm fine, it's just those initial steps or bending/squatting/sitting that are problematic. I'm still pissed about my hair loss, though. I was hoping it would grow back once I got off prednisone, but then I read somewhere that 6MP can also contribute to hair loss. I may have to resort to shopping for a wig. As far as my UC symptoms, though, I would have to say they are improved and tolerable. I still have to make 2 or more trips to the bathroom in the mornings, but after that, I'm usually good for the day, and the sense of urgency has gone away. I no longer fear plane trips or public places. I have also stopped obsessing over food. I have tried eliminating all kinds of "bad foods" from my diet, and it didn't make a whit of difference. Even so, I have reduced or minimized my consumption of caffeine, sugar, carbonated beverages, fruits with skins/seeds, red meat, raw vegetables, and gluten/carbs.
I was hospitalized in September 2010 for six days with a bad flare. I was put on Colazal when I was released. A little more than a year later I had another flare, but this time I met up with the doctor in time to prevent myself from being hospitalized again. I started 6MP (one tablet daily) in January of 2012, and my flare went away. Nine months later another flare started to creep in. By January things were pretty uncomfortable-- BMs 6-8x/day plus a few trips at night. Rather than up my dose of 6MP or start on Prednisone, I decided to try the SCD. I have been following it (loosely) since late January 2013 and I feel completely normal now. Almost six weeks ago I began to taper off the 6MP (I'm down to 1/2 a pill). In a couple days I will cut my dose in half again (1/4 pill) for six weeks and then stop completely.
There are warnings out there that adverse effects from 6MP can show up months or even years after stopping the drug. One thing I've noticed is that I have a strange tiny red dry patch of skin on my chin near my mouth. It started to appear shortly after I lowered my dose of 6MP, and It has been camping on my face for at least a month! I also notice that when I get a pimple, it has a strange personality. It hurts--sort of stings a little--and is watery inside. I try to avoid popping them because they just become a mess that reinvents itself. They hang out on my face for much longer than they used to.
My advice is: PLEASE PLEASE PLEASE try the SCD. Be careful about the drugs you choose, because they may seem like miracles at first, but once you stop taking them, they could bring on a whole slew of problems for you... I sure do hope that I can continue to see positive results from the SCD so that I can avoid poisoning myself with these crazy drugs. It's interesting that such a tiny little pill can affect your body in such a drastic way.
Was on 6 PM for 6 years and did fairly well....or so I thought. Had a major flare, June 2012. Ended up in hospital for 3 weeks. Turns out that the 6mp destroyed my bone marrow, White and Red blood cells, platelets amongst other things. Turns out that my GI doc never monitored me for these items. Supposed to be monitored every few months.
6MP...I Guess Not For Me
When I was diagnosed my GI started me on Asacol, but I unfortunately developed an allergic reaction to it (pancreatitis) and had to stop. I was put on prednisone, then finally asked to try 6MP this past January. Got up to 75mg/d with no real change in my UC symptoms (cramping, urgency, tenesmus, blood, incontinence, etc), but my GI just called me today and said to stop the 6MP immediately. My white blood cell count is too low and it's also starting to effect my liver. So, back to the drawing board after some more labs later this week. All in all if this drug had worked for me I would have been kind of okay taking it since the only side effect I experienced was slight nausea at about the same time every day. It's hard to tell how well it really "worked" for me, though, because I'm still on a relatively high dose of prednisone. Guess 6MP was not meant to be.
I have been on 75mg of 6mp for about four months now. The side effects were pretty hardcore at first, but have eased off a bit now. In the beginning I was throwing up every morning, Zofran is helping with that now. I ran out of Zofran the other day and sure enough, I was extremely nauseous and threw up. My hair thinned quite a bit, and I have developed painful bumps on my scalp. Itchy and painful! I also have severe joint pain, which could be a side effect, or it's because of autoimmune disease. Not sure yet. I had a colonoscopy a week ago, and it showed a lot of inflammation, ulcers and mucus all throughout my guts, so I guess 6mp is making my life a bit more liveable, but am still not in remission. Still running to the toilet 5-7x day. My DR is talking about starting Humira, but I'm REALLY reluctant. It's all a crap shoot. (intentional pun)
good but bad
6mp helped me out of a flare after I had been on a few runs with Prednisone and it was confirmed that I had become steroid-dependent. I was worried that i would get sick or die from 6mp, but At the time it seemed to be the best choice. After ten months on6mp I had another flare,found this website and decided to try the SCD. Within a few weeks my symptoms were gone! I am still on 6mp (it's been about 13 months) but pretty soon I will be stopping all medications (I'm also taking Colazal). 6mp has been ok for me but I Ferrell like it's making me age more quickly and i can't help but think it's taking the vitality from many blood and cells.
6mp 10 years and counting
Was diagnosed with UC at age 13. Went on prednisone, asacol, and 6mp. Been on asacol for 10years. prednison needed for flareups. Been on the 6mp for 10years now, and it works well to keep me in remission however I have concerns about the long term effects and pregnancies which I plan to have kids. My liver enzymes are closely monitored but my gastro doc warned me that I eventually will not respond to 6mp and will need to go on remicade which I'm afraid. Powerful drugs.
I have been using 6mp for over a year taking 1.5 tablet so my doctor says I have a steady 6mp lvl In my blood. I haven't noticed any results or relief from my extreme symptoms on this. My diet is all I can notice from a day to day if I'm not on something extra like prednisone. I can't take Asacol, I started my treatments with that, until one day I ended up in the emergency room at 21yrs old suffering from pericarditis.. A very long four days of recovery and learning I'm a rare case of allergies to the primary UC med..
6MP: Not for me
I was on 6-MP for a grand total of two weeks during my first flare. It was shortly after I got out of the hospital after we found out I was allergic mesalamine drugs. The first week went fine, and I actually felt pretty good. The second week, on the other hand, was another story. I was debilitatingly weak to the point that I could barely get out of bed. I was nauseous all of the time and throwing up when I did venture to try and eat. Not even Zofran was helping with that. On top of that, I kept getting palpitations and difficulty breathing and could barely go four words without crying. It was miserable. I called my doctor who made me come in ASAP (love my doctor by the way) to have labs drawn and found out I was toxic. So needless to say, worst drug ever.
Not for me...allergic and being masked by prednisone...as I tapered the pred. Boom...nasty forever rash from my neck up. Still have remnants of rash on my forehead-forever reminder. Felt terrible on it and it even straightened my curly hair-No Joke! Be careful!
worked one time but not the next
i used 6mp along with prednisone, remicade, flagyl, cipro, and canasa to get in remission the first time around. it's hard to know exactly what was working, but i feel like the 6mp made a difference. i know this because when i had to stop it due to high liver enzymes, all my symptoms came back even though i was on remicade, too. when i got back on it at half the dose, it did't do anything. i think the 50 mg dose was effective for me but also damaging to my liver. the 25 mg dose was not strong enough.
Every time I encounter a flare up, the routine is: quick fix - prednisone plus increasing doses for Azathiopurine. I finally got to the point from starting with 50mg to maintaining in remission for 6months on I believe somewhere from 200-300mg. Along with this dose, Asacol 400mg (4 pills 3x a day) - I thought this combination of 6-mp and Asacol will finally put me in remission for longer than 6months, but I suddenly had a severe flare. I maxed out my dose for using this 6-mp after doing promethues blood lab results - so then tried remicade with only 100mg of the 6-mp azathiopurine. The combination wasn't strong enough so now I'm on 10mg/kg bags of Remicade infusion along with 200mg of the azathiopurine (6mp) and Asacol (12 pills each day). The only thing I never liked when going on high doses of the azathiopurine is the intense nausea I get! It wakes me up in middle of night having to need to eat otherwise I feel I'll vomit or pass out!
I think 6mp might have been toxic to me. When I was on it, my entire body was stiff and in pain. It made me feel like an arthritic 90 year old with the flu, which was weird to me at the time because I knew uc sufferers who've raved about the benefits of 6mp. And even though I kept on complaining, my GI made me stay on it for a couple months until I finally just told him that I was done poisoning myself. Oh, & it really didn’t help with my uc symptoms. Once I stopped taking 6mp, I started feeling less & less like I had one foot in the grave. After about 10 days off it, I was back to my normal ibd symptomatic self. If I could, I wouldn't give 6mp any stars!
I used 6-MP along with the Lialda to control a flare. I had good results but I was also taking golimumab injections in a drug study. Did not notice any side effects until I had to discontinue due to the diagnosis of kidney cancer.
Not All Bad
I was on it for a year and it put me into remission which was great. I didn't have any side effects other than towards the end it made me anemic and I had to come off it.
