Hi,

I would like to CTB by this method is it reliable? I'm on 40mg got 200 pills atm. I know anything above 2mg is supposedly lethal but just wanting advice from those more knowledgeable about the drug. Does an overdose from it hurt (for those who've ever tried) I've had a paracetamol overdose many times and have been in agony and of course I'm still here.

Sorry what do you mean? I'm asking for a human lol
LD50. Similar term(s): lethal dose 50, median lethal dose, LC50. Definition: The amount of a chemical that is lethal to one-half (50%) of the experimental animals exposed to it. LD50s are usually expressed as the weight of the chemical per unit of body weight (mg/kg).

I wouldn't recommend it. I don't remember how much propranolol I took but all that happened was I spent a week in the ICU with pneumonia.

Did you become unconscious? Were you found? What happened when you took the overdose apart from the pneumonia. Did you puke or experience any pain?

I was never unconscious, my breathing got more difficult and my blood oxygen was in the 60s. I don't live alone so I had to suck it up and go to the hospital.

According to this site https://litfl.com/propanolol-overdose/

Any ingested dose of propranolol > 1 g is considered to be potentially lethal.

That said, there are multiple factors here. An adult man may weigh twice as much (if not more) than an adult woman, which has an impact. Someone may have a preexisting condition, making them more vulnerable to the effects of propranolol. It is possible to die by propranolol alone, there are documented cases of lethal overdoses. You should keep in mind though, that:
  1. It takes time. @Tonkpils your CTB attempt might have been successful if your plan included not being found for several hours.
  2. It's hard to estimate how much propranolol is enough. There are people who died after 5g, there are people who survived 8.
  3. It's relatively easy to save your life if you get found. There are cases of people saved a couple of hours after ingestion.
Bottom line is: if you want quick and reliable, this isn't the right method. Otherwise keep in mind everything that can go wrong.

EDIT: I forgot about puking. That's risk #4. Imagine you down your 200pills and after a while you throw up. You might ingest just enough to put you in a coma but not enough to kill you. Then what?

I didn't go to the hospital until 4 days after I took it, the doctors said the pneumonia "might" have killed me but it was uncertain. I didn't tell them I took anything so it was a mystery to everyone.

Now the mystery is how much you took. That would shed a lot of light on the subject dose-wise.

About 1.5 grams, at the time I weighed 300 lbs so that may be a factor as well.

That explains it. I weigh around 200lbs, maybe slightly more and I've been wondering if 10g would be enough to get the job done, given what I've read in some articles.

If you could manage to swallow all 10 g it should be enough. I found 2 reports where a lethal dose was 4.8 and 6 grams.

Doses above 1.5 grams are at greater risk of seizures as well but at that high a dose I think the cardiac effects would render one unconscious quickly.

I wouldn't do that. I used 21 grams of phenobarbital and 3 grams of morphine, I fell into a coma and here I am. Propanolol isn't even close to phenobarbital + morphine

Those aren't really comparable considering they aren't even close to the same class of drug.

Different drugs different methods of action. Phenobarbital is much less potent than pentobarbital(nembutal) and is not recommended to OD on. Also each person metabolizes drugs differently, another reason why overdose is not reliable.

is it worth trying? in the UK can't get SN, but i have propanolol prescribed to me… 40mg tablets, 73kg - how many tablets needed for that?
i could top it up with sertraline and mirtzapine too?

i just need a plan. even if i don't CTB anytime soon, i hate hate hate not knowing what my method will be failing getting SN. i'm thinking either OD on this, or CO in a tent, and it's so pathetic but it's cold outside, and i'd like to be as comfortable as possible in my last minutes. hence, enquiring about propanolol now.
