Some of the symptoms induced by the TTX are headache, diaphoresis, body numbness, dysarthria, dysphagia, nausea, vomiting, abdominal pain, generalized malaise, weakness, and lack of coordination and, in more severe cases, hypotension, cardiac arrhythmias, muscle paralysis, and cranial nerve dysfunction may develop.
Is there an antidote for puffer fish?

Can you survive a puffer fish sting?
Pufferfish Poisoning Symptoms Symptoms may progress to paralysis, loss of consciousness, and respiratory failure, and can lead to death.
How does TTX kill?
Tetrodotoxin kills because it can interfere with our nervous systems. It blocks sodium channels, which carry messages between the brain and our muscles. As a result, those suffering from tetrodotoxin poisoning initially lose sensation. This is rapidly followed by paralysis of muscles.
Is there a cure for tetrodotoxin?
There is no known antidote. The mainstay of treatment is respiratory support and supportive care until the tetrodotoxin is excreted in the urine. Activated charcoal and/or gastric lavage can be done if the patient presents within 60 minutes of ingestion.
Can you survive tetrodotoxin?
Death may occur as early as 20 minutes, or as late as 24 hours, after exposure; but it usually occurs within the first 4 to 8 hours. Patient/victims who live through the acute intoxication in the first 24 hours usually recover without residual deficits.
