In addition to the toxicity of ethanol, the main psychoactive component of alcoholic beverages, other physiological symptoms may arise from the activity of acetaldehyde, a metabolite of alcohol. [11] These effects may not arise until hours after ingestion and may contribute to a condition colloquially known as a hangover .
Symptoms of ethanol overdose may include nausea, vomiting, CNS depression, coma, acute respiratory failure, or death. Levels of even less than 0.1% can cause intoxication, with unconsciousness often occurring at 0.3–0.4%. [17] Death from ethanol consumption is possible when blood alcohol levels reach 0.4%.
The initial symptoms of methanol exposure are usually less severe than the symptoms from the ingestion of a similar quantity of ethanol. [6] Once the initial symptoms have passed, a second set of symptoms arises, from 10 to as many as 30 hours after the initial exposure, that may include blurring, photophobia, snowstorm vision or complete loss ...
Early symptoms include intoxication, vomiting and abdominal pain. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. [1] Long term outcomes may include kidney failure and brain damage. [1] Toxicity and death may occur after drinking even in a small amount [1] as ethylene glycol is more toxic than other diols.
In 2019, a 25-year-old man presented with symptoms consistent with alcohol intoxication, including dizziness, slurred speech and nausea. He had no prior alcoholic drinks but had a blood alcohol level of 0.3 g/dL. The patient was given 100 mg of the antifungal fluconazole daily for 3 weeks, and his symptoms were resolved. [8]
Foreign Office advises tourists how to avoid alcohol that may be accidentally toxic or may be counterfeit
The resulting intermediate, acetaldehyde, is a known carcinogen, and poses significantly greater toxicity in humans than ethanol itself. Many of the symptoms typically associated with alcohol intoxication—as well as many of the health hazards typically associated with the long-term consumption of ethanol—can be attributed to acetaldehyde ...
Other symptoms: Ant bites are typically painful and itchy. In addition to the bites, fire ants use their stinger to inject a venom called solenopsin, which causes a burning sensation, Frye says.
