Whats OD range for methylphenidate?

Swim was doing a bit of reading on erowid and came across a ritalin trip report and in it erowid says this " [Erowid Note: 230 mgs of methyphenidate is considered an extremely high dose]"

Is that true? What are the signs of a ritalin OD? Dunno exactly how much swims done before but hes definitely done 200mg or more in one night. Not all at once though so id say that helped.

Re: Whats OD range for methylphenidate?

230 mg is a shit ton, but the OD range depending on your weight and tollerance can range from 240 to 300. The actual cause of death from ODing on this stuff is either from a heart attack or Seretonin Syndrome which can be induced by mixing it with other drugs. If you get Seretonin Syndrome (which is the imbalance of Seretonin in your brain) and you don't get help imidiately your pretty much fucked. Be really careful with this stuff you seem like you have a built up tolerance if you can handle more than 200 mg.

Re: Whats OD range for methylphenidate?

Yea swim rips through 200mg without a bother. He gonna be careful from now on though cuz hes definitely done over 200mg at least once and a couple of times he noticed his heart beating like mad.

Re: Whats OD range for methylphenidate?

If you're resting heartbeat is over 200 beats per minute its a good idea to just chill until your back at your usuall heartbeat when on ritalin.

Okay, this is a two year old post, but in case somebody reads this: IF YOUR HEART RATE IS 200 BEATS PER MINUTE, CALL AN EMERGENCY NUMBER IMMEDIATELY

Merck index indicates its 190mg/kg which is the ld50 for methylphenidate

good research so at 212lbs or 100kg - 19,000 mg would kill only 1 /2 my identical hyopthetical clones. These figures make haxxxor's ludicrous claims well ...ludicrous

In that case over 200mg might be a high dose, and could maybe cause discomfort, but it is not anywhere nere ODing

Re: Whats OD range for methylphenidate?

SWIM has gone as far as to inject 600mg (two boxes of 10mg) in about 12-15 hours, methylphenidate seems to have cross-tolerance with cocaine for SWIM, first he injected 100mg at once and it was one hell of a ride, and then injected 50mg at a time for the flash and to prolong the effects, the last shot was 120mg and made SWIM have the typical symptoms of a stimulant overdose, heartbeat at 178, profuse sweating, shaking uncontrollably and the “distilled terror” feeling from so much adrenaline over-stimulating the part of the brain that handles fear.

The LD50 is probably for mouse or other small mammal; it cannot be used to determine toxicity in humans is just a measure of general toxicity and by that data methylphenidate is twice safer that cocaine (LD50 95mg/kg).

For a first time user going over 60mg at once could be too much, its better to start slow on SWIY gets used to the drug and effects individual differences in natural tolerance levels can be drastic.

General limits are don’t go above 100mg at once snorted/swallowed and above 60mg injected IV until SWIY is experienced with substance in question and those are limits SWIY should start much lower than that perhaps 50-60% less.

Remember that methylphenidate isn’t “kiddy coke, is a very powerful drug that must be respected and treated with care.

Note: Do not try imitate SWIM actions described in this post: its extremely dangerous and it might kill SWIY, please be cautious and don’t become an statistic.

Yes you can OD, it doesn't matter what your tolerance is you can ALWAYS OD if you continue to increase the dose. Methylphenidate is not a fun drug to OD on trust SWIM on this one.
Also when taking doses far above the maximum clinical dose the increase does not always lead to a predicable effect (i.e doubling the dose does not necessarily mean that you will get double the effect).
To clarify with mentions of LD50. LD50 is lethal dose for 50% of the population as in 50% of the people who take that dose will die, it is a number you wouldn't want to be anywhere near. It doesn't give any information about toxicity or OD's which can be far lower. (The clearest example of this difference is LSD whose LD50 is far far greater than a dose one would take)

To answer the original question signs of an OD: ones that will be noticed: increased heart rate, increased body temp, lethargy, agitation, its possible to get hallucinations and seizures as well.

Re: Whats OD range for methylphenidate?

^^^I am still alive...go for it? I hardly think that's a ringing endorsement, do you? Just because one person can take ridiculously high doses of a stimulant drug does not mean that someone else will be able to do the same thing...does it? And yes, you can OD on uppers, its usually mimics a heart attack.

Now come on, lets keep it real, but safe too. Remember the harm reduction ethos that DF prides itself on, it's there for a reason.

Re: Whats OD range for methylphenidate?

I've known a couple of people who have died from Stimulant ODs, not pretty to watch. But I do get what you're saying. It's like in the UK, ADD/ADHD for adults in non existent (virtually) and you go to almost 99.9% of GPs here and tell them you need meds for your ADD/ADHD they'd laugh (or be astounded) you out of their surgery.

Strange that, isn't it?

Re: Whats OD range for methylphenidate?

I just injected 60 and 100 an hour later (I've only IVed anything a dozen times). I feel nice; no palpitations or anything. I might try another100 in a bit and snort decreasing amounts to taper the high. I wish I knew where to buy weed.

Re: Whats OD range for methylphenidate?

I'm going to use Focalin terms (which is twice as strong as ritalin both otherwise exactly the same) so imagine the amount of milligrams of focalin I say is doubled and that is how much ritalin milligrams there are. The amount it takes to overdose is very flexible because of how easily you build a tolerance to it. If youve never taken it before then 15 milligrams is the most you could take until you get high from it but if you're trying to get high off of it then 20-30 milligrams is the amount you should take first time. I'd say if you've never taken it the lethal dose would he somewhere around 80-100 milligrams. Swim has built up such a tolerance that he takes 115 milligrams with no problem. If you take that 20-30 milligram amount a few times then you'll notice it'll get you less and less high. You'll then move to like 25-35 and so on. The tolerance for focalin builds up extemely fast and the lethal dose will get bigger and bigger depending on your tolerence. One man might OD on 100mg and another on 300mg. It also just depends on if your heart can handle working that hard. Swims rule is that he doesn't take more than 40 mgs more than the last time he did it.

Post Quality Evaluations:
Please do not use SWIM https://www.drugs-forum.com/forum/showthread.php?t=197306
I agree that 80-100mg with no tolerance is unhealthy Im not aware of any literature supporting it being "lethal"

You need to down atleast 14g of methylphenidate for it to be fatal theoretically. If you got a weak heart and mix 200mgs with other stuff than it get really bad.

Makrill added 115 Minutes and 44 Seconds later...

Then it can* get really bad
