Fentanyl Citrate IM dose?

Here's my question: I have an ampule of Fent Citrate I want to try out. I do about 12 to 15 mgs of morphine sulphate via IV every few days or 2 to 3 mgs of hydromorphone IV, depending on what I have on hand. I know the Fent is 50 to 100 x's more powerful so I understand the ug's versus mg's conversion. I want to do the Fent IV but I'm worried about the muscle wall rigidity thing from slamming it; breathing is kind of important to me. What about just IM injection? Any experience? And if I start at 25 ug's, via IM, will I even feel it?
 
From what I understand, 50-100mcg IV is standard for pre and post op stuff

But I'd wait for someone with personal experience. I think 12mg of morphine is 120mcg of fentanyl

Be smart though, start small. Especially with something as dangerously powerful as fentanyl
 
My best guess is that a dose would be around 100-150ug (though it could be more, don't be surprised, just smart small) - but don't push that whole amount at once. I'd say shoot 100ug (I'm sure you can handle that if you can handle 10mg morphine IV), then titrate your dose from there. If you want a faster onset so you can see if its enough sooner and if you need to dose again, you might want to try IV. On the other hand, if you IM, you can wait 5-10 minutes between shots and not worry about turning a pincushion.


(Source: I used to do billing for the anaesthetia department of a hospital, so I looked at numbers like this a lot.)
 
Doubt you'll feel 25 mcgs even if you IV it. Try around 200 mcg if you can acquire that much and have a decent tolerance.

Thanks for the input guys. I think I'll just go IM first to be safe. I've been reading more about that muscle wall contraction that stops your breathing and it scares the balls off me but it only refers to IV occurrence; nothing about IM. But still, it doesn't seem 25 micros would do that even IV...?

I can't really titrate slowly because I can't stand there with a needle and syringe in my arm for 10 minutes. I have plenty to play around with it for a few days so I guess we'll see. The delaudid and MS are not as fun anymore. I did 1.4 ml's earlier (3hrs ago) from a 10mgs per ml vial and its already worn off; the rush was limited too. I used to like the delauded more because it was a smoother orgasmy rush but now I'm preferring the morphine because its a pins and needles in my neck kind of rush. I have a ton of that shit upstairs but I'm going to leave it alone for a couple of weeks and start over. After 5 or 6 days, it takes that long to get a good rush back without having to do cancer patient doses to get high.
 
For a tolerance of 10-12mg morphine IV or 2-3mg hydromorphone IV, 25micrograms of fentanyl will not do anything (unless you're one in a million and super sensitive to fentanyl, which is quite a stretch.)

I used to look at the doses used for anaesthetia in surgery. The average person seemed to receive about ~50ug fentanyl (on average, I would assume these were people with no tolerance, or maybe people who took something like 2 vicodin a day ;) tops). Some super old people would get less (~25ug), and some would get more like 100ug fentanyl (though not always at once). I also saw people who received hundreds of micrograms, but I figured they either had preexisting tolerances or were in surgery for 12 hours.

Im assuming these large mg doses are because they were over an extended period of time and because fent is a really short acting opiate?
 
^ Damn it, I haven't gotten a lot of sleep lately; I typed "micrograms" out earlier, and for some reason fucked up afterwards and used "mg" when I meant "ug" (or "mcg"). Those doses are 1000x normal doses, so fortunately if anyone read that before I changed it they would have known it was a typo (or shot 1000 vials 8)).

[fixing the previous post]
 
Ive shot a whole 100mcg patch before, and it didnt do diddly shit. No rush, heavy nod tho. I was used to doing K8s and morphine 60's on a bad day, so take that as you will.

Please don't listen to this guy. He's dicksizing and saying he IVd over 10mg of fentanyl. I'm thinking he doesn't understand that there is significantly more than 100McG fentanyl in a 100McG patch.

Please start small and work your way up. Maybe start at 50McG and take it from there. Don't redose for at least a few hours.
 
Yeah, I kinda get that idea. I looked at all the vials I have; they are all blue striped 2ml ampules @ 50ug / ml. so 100ug per ampule. I will start at 50ug IM just to be safe. I do love the rush of IV opiods but I just can't chance breathing thing; call me chicken shit I guess!
 
Another thing to consider with Fentanyl: It has no pronounced rush. <~ This may be different with IV/IM, but from my experience with buccal Fentanyl combined with others statements on this topic bring me to that conclusion. This can be very dangerous since it can leave one thinking they have under-dosed while they have in fact, dosed enough.

Just becareful with the stuff, and make sure you wait long enough and pay attention to your body before re-dosing, if you think you had under-dosed.
 
Well, so much for that. Thanks for all the help and input guys. I decided to be careful like I said and started with 50ug IM. Waited 20 minutes or so and .....dick....nada....so did another 50ug IM. After about 8 minutes I felt just a little tiny tiny body buzz like MS but not much else. Hell, it barely even got rid of my slight back ache. After 40 minutes or so, completely gone.

Still not to sure I'll IV it though; if there's no rush to it, then its not for me. :p Maybe if I get some saline flushers to mix it with. Think I'll go grad some diazapam and chill the f' out. Thanks again guys.
 
fentanyl should be cooked with vitamin C solution or vinegar. use VERY small amounts of fentanyl, like cut a 100mcg patch into like 10-12 pieces and go from there.

Do not cook the fentanyl with vitamin C. You have sterile vials. Doing anything beyond shooting that with a sterile needle is illogical.

You will not experience the IV respritory depression from such a small dose. 10mg of morphine/100mic of fentanyl is a very standard dose in the hospital. You have been using for a bit and I am sure you could shoot much more than you are using now.

Fentanyl has a wide range for cross tolerance, but when it comes to such a small dose you will be fine. IV 120ug will be perfect because it is equivalent to 12mg of morphine, yet the cross tolerance will boost the high a little bit more than you are used to and you will receive effects that are more close to what you desire- you are a conservative doser clearly. Not a bad thing, I am as well. But it's boarder line paranoia rather than being cautious.

How long have you been using? And never shoot a patch btw or listen to anyone who claims they shot 10mg of fentanyl aka 1000mgs of IV morphine with a 25% cross tolerance that's 1250mgs of morphine. Anyone who can do that would throw aline in there like "I have been using for years and have a crazy tolerance".

IV fentanyl high is ten-fifteen minutes. Not shit. So I hope you don't pay a lot.

I take 480mg of oxycontin daily or I am prescribed it, but I abuse and save pills since my tolerance doesn't require nearly that much. That being said, I receive 350ug of fentanyl for post op pain (I have frequent surgeries), and 200ug while I am under anesthesia. Thats them assuming I have 65mg-70mg tolerance to INSTANT relase oxycodone if I was to take my pills as prescribed. It's actually a lot higher, but this is what the doctors are assuming, and 350mics gets me pretty well sedated/without pain.

Long post, but there is some really misguided information here that needs to be cleared up.
 
Thanks SCO; I am conservative and like you said "a little paranoid" too since this was first time with Fent. I will try again tomorrow via IV and see how that goes. I don't mess with patches or any of that stuff and am lucky enough not to actually have to pay for any of this stuff.
 
quick question I have a vial of 2mL Fentanyl Citrate for injection (100 mcg Fentanyl/2 mL It says it's for IV or IM use, what is IM and can I drink this instead of injecting?

Any help is appricated. Thanks
