Presentation
Case presentation A 17-year old Sri Lankan male (body weight – 42 kg), presented to a local hospital 1 hour after self-ingestion of nearly 500 ml (4.3 g/kg) of liquid Propanil (concentration – 360 g/l). [bmcresnotes.biomedcentral.com]
Above 70% of this depletion, the reactive N-acetylimidoquinone metabolite will begin to react with nucleophilic thiol (-SH) groups that are present on hepatic and renal proteins. [pharmaxchange.info]

First Aid EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. [cameochemicals.noaa.gov]
If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. [nilechemicals.com]
Entire Body System
- Anemia
In experiments on two dogs the first effect of daily acetanilid ingestion was an anemia. Following prolonged administration the animals gained tolerance. [jpet.aspetjournals.org]
These aniline derivatives can cause methemoglobinemia and hemolytic anemia. [pharmaxchange.info]
For patient education resources, see Anemia. [emedicine.medscape.com]
Chronic poisoning by acetanilide may lead to anemia & sulfhemoglobinemia, with discoloration evident in conjunctival & retinal vessels. Drug Warnings: 1. Acetanilide is especially dangerous in anemia, after hemorrhage and during menstruation. 2. [slideshare.net]
(NTP, 1992) Health Hazard SYMPTOMS: Symptoms of exposure to this compound may include contact dermatitis and eczematous skin eruptions; anemia and cyanosis. ACUTE/CHRONIC HAZARDS: This compound is an irritant. [cameochemicals.noaa.gov]
- Weakness
Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. [cameochemicals.noaa.gov]
In example, one out of the 19 persons in the main study showed a weak response to aniline only (‘non-responder’) in terms of a baseline level of 0.93 prior to exposure and a maximum observed saturation level of 1.0% at the end of exposure thus resulting [echa.europa.eu]
Mild poisoning with acetanilide causes headache, weakness, hypotension, nausea & vomiting & with more severe poisoning there is depression of cardiac & smooth muscle. 5. [slideshare.net]
[…] associated with higher levels of methemoglobin are as follows: 3-15% - Slight discoloration (eg, pale, gray, blue) of the skin 15-20% - Cyanosis, though patients may be relatively asymptomatic 25-50% - Headache, dyspnea, lightheadedness (even syncope), weakness [emedicine.medscape.com]
- Unconsciousness
One should never give anything by mouth if the victim is unconscious. Immediate medical assistance is important. [chemistrylearner.com]
If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. [cameochemicals.noaa.gov]
Never give anything by mouth to an unconscious person. Get medical attention. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. [nilechemicals.com]
- Gastric Lavage
However gastric lavage was not done and activated charcoal was not given. Subsequently, the patient developed marked respiratory difficulty, central and peripheral cyanosis and drowsiness. [bmcresnotes.biomedcentral.com]
- Weight Loss
[…] another potential dietary cause of methemoglobinemia. [35] Other substances that can cause methemoglobinemia include the following: Copper sulfate Organic compounds – Sodium chlorite, [36] ammonium carbonate (smelling salts), [37] and 2,4-dinitrophenol (weight [emedicine.medscape.com]
Respiratoric
- Cough
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. [cameochemicals.noaa.gov]
Gastrointestinal
- Vomiting
DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. [cameochemicals.noaa.gov]
Contact your doctor or emergency room at once if you develop severe stomach or back pain; black, tarry stools; vomit that looks like blood or coffee grounds; or unusual weight gain or swelling. [sale-meds.com]
Mild poisoning with acetanilide causes headache, weakness, hypotension, nausea & vomiting & with more severe poisoning there is depression of cardiac & smooth muscle. 5. [slideshare.net]
Ingestion: It is not advisable to induce vomiting without proper direction from a qualified physician. Any tight clothing like tie, collar and waistband should be loosened. One should never give anything by mouth if the victim is unconscious. [chemistrylearner.com]
- Nausea
Mild poisoning with acetanilide causes headache, weakness, hypotension, nausea & vomiting & with more severe poisoning there is depression of cardiac & smooth muscle. 5. [slideshare.net]
Anacin's side effects may include dizziness, heartburn, irritability, nausea, nervousness, rashes, hives, bloody stools, drowsiness, hearing loss, ringing in the ears, and trouble sleeping. [sale-meds.com]
Clinical features include; gastrointestinal irritation causing abdominal pain, nausea and vomiting, central and peripheral cyanosis due to methaemoglobinaemia, headache, dizziness, stupor, convulsions, bradycardia, hypotension, respiratory depression, [bmcresnotes.biomedcentral.com]
- Blood in Stool
Anacin may reduce the number of clot-forming cells (platelets) in your blood. To prevent bleeding, avoid situations in which bruising or injury may occur. Report any unusual bleeding, bruising, blood in stools, or dark, tarry stools to your doctor. [sale-meds.com]

Prognosis
Prognosis The prognosis of mild cases of methemoglobinemia is very favorable. In severe cases, the prognosis is determined by the degree of anoxic end-organ damage. [emedicine.medscape.com]
Etiology
The presence of anemia and cyanosis despite oxygen treatment results from both of these effects. [4, 5] (See Pathophysiology and Etiology.) Methemoglobinemia occurs when red blood cells (RBCs) contain methemoglobin at levels higher than 1%. [emedicine.medscape.com]
