The effects of Sodium Nitrite[edit]

Sodium Nitrite, NaNO2, acts as a catalyst in the conversion of the hemoglobin in your blood into methemoglobin (MetHB), a molecule with a much higher affinity with oxygen. This occurs when the ferrous ions in the regular hemoglobin are converted into ferric ones. Since its affinity is so high, methemoglobin cannot let the oxygen flow into other tissues that need it, thus depriving them of oxygen even while you're breathing. Death, then, occurs by hypoxia. The nitrite-derived NO signalling is illustrated in Fig. 1. Sodium Nitrite poisoning symptoms include nausea, vertigo, vomiting, headaches and, should you manage to not pass out for too long, seizures.

The PPH claims that, during a monitored suicide with SN, the patient was unconscious at 12 minutes and dead by 42. However, some sources claim that SN poisoning might take as much as 8 hours to kill, probably due to low dosage. Since methemoglobin creation is a natural process in our bodies, you must be aware that a certain enzyme works to transform it back into hemoglobin again. This is why the recommended dosage has varied on the PPH so much, as the synthetization of these enzymes and their "power" to overcome the formation of MetHB depends purely on your body, thus making a normal, general dose for all who chose this method very hard to determine, unlike N.

As for the physical symptoms your body will experience, not much will really change. Since your blood will mainly be MetHB, it will take on a bluish chocolate brown color, and the tips of your fingers, toes and nose (amongst others) will turn slightly blue from cyanosis.


Strong enough antiemetics for this method are not OTC, so you'll need to see your way around this. You're looking for Metoclopramide or any of its commercial names, like Reglan/Primperan. This antiemetic needs to be a Dopamine blocker for it to work. Antiemetics aren't 100% necessary for this method, however; just like with N, you won't accomplish anything if you end up puking it all out, which is likely. This will also most likely be the bulk of the money you'll use during this method.

Stat dose (60 minutes before SN intake)

• 3 * 10 mg Metoclopramide


Ahead regimen (48 hours before SN intake)

• Take 10 mg Metoclopramide every 8 hours, i.e. 3 times per day, starting 48 hours in advance.

Acid Regulators[edit]

Another thing recommended in the PPH is decreasing your stomach's fluid volume to make the SN absorbed more quickly. This can be accomplished with drugs like Tagamet (The one recommended in the PPH, 800mg).

Stat dose (30 - 45 minutes before SN intake)

• 800 mg of Tagamet (Cimetidine)


• 3 * 75 mg Zantac (Ranitidine)

It should be noted that the PPH previously recommended sodium bicarbonate as absorption accelerator, which, it argued, would raise your stomach's fluid pH. But since the release of at least October 2018, the PPH has argued "this effect is not related to gastric pH, but rather to the production rate of acid."

Sodium Nitrite[edit]

The main compound for this method, Sodium Nitrite is easy enough to find. You're looking for >98% purity Nitrite. This chemical is sold without regulation and can be bought from Amazon, Ebay or any lab supplier in your area. 100 grams cost between 8 and 10€. This chemical is completely legal to own and is used during curation of meats to preserve their color. It's described as "White to yellowish powder/crystals" and it's said to have "slightly salty taste". It is also very soluble in water.

The recommended dose from the PPH is 15 grams, however, this has increased on different issues, from only 5, to 12 and now to 15. Very important: You're looking for Sodium Nitrite, not Sodium Nitrate; NaNO2, not NaNO3.

Should you not find it just by looking up Sodium Nitrite, look for: NaNO2, NNaO2 or Filmerine. Make sure you're buying what you want and that its purity is high enough. For more information on it plus some industrial sellers, check Sodium Nitrite on Pubchem.

A few extra comments

I recently got asked a few things regarding SN. First of all, you must know that the effects of this poisoning are completely reversible. It is very unlikely that you will have any permanent damage should you be "saved" during your attempt. Secondly, since this method relies on hypoxia, cardiovascular problems will reduce the amount of MetHB in blood needed to actually kill you. This, however, shouldn't really be a problem since it is usually sold starting from 100 grams, far more than the amount needed.

Lastly, there have been cases of people recovering from SN poisoning without any "side effects", but even if the ambulance is called soon enough, it is not certain that you will survive.
