Atropine/Belladonna/Datura Poisoning: Causes, Symptoms, and Treatment


Atropine/belladonna poisoning is a potentially dangerous and life-threatening condition caused by ingesting or coming into contact with the toxic compounds found in plants like deadly nightshade (Atropa belladonna) and other related species. This article will explore the origins of atropine and belladonna, common causes of poisoning, symptoms to look out for, diagnosis, treatment options, and preventive measures.

The Origins of Atropine and Belladonna


Atropine is a naturally occurring alkaloid found in various plants of the Solanaceae family, such as deadly nightshade, Jimson weed, and mandrake. It is a powerful anticholinergic substance, meaning it blocks the action of the neurotransmitter acetylcholine, which is responsible for various physiological functions, including muscle contractions, heart rate regulation, and digestion.


Belladonna, also known as deadly nightshade, is a perennial herbaceous plant native to Europe, North Africa, and Western Asia. The plant contains high concentrations of atropine and other toxic alkaloids, such as scopolamine and hyoscyamine. These compounds give the plant its poisonous properties, which have been well-known since ancient times.

Causes of Atropine/Belladonna Poisoning

Accidental Ingestion

One common cause of atropine/belladonna poisoning is accidental ingestion of the plant or its parts, such as the leaves, roots, or berries. Children are particularly at risk due to their curiosity and the plant’s attractive, shiny black berries.


Atropine is used in various medications, such as eye drops, anti-spasmodic drugs, and treatments for certain heart conditions. An overdose of these medications can lead to atropine poisoning, causing severe symptoms and complications.

Exposure to Contaminated Products

In some cases, atropine poisoning can occur when people consume contaminated products, like herbal supplements or teas containing belladonna. Unregulated or mislabeled products pose a significant risk, as they may contain dangerous levels of toxic compounds.

Symptoms of Atropine/Belladonna Poisoning

Early Symptoms

Atropine/belladonna poisoning symptoms can vary depending on the amount ingested and individual sensitivity. Early symptoms may include:

  • Dry mouth
  • Dilated pupils
  • Blurred Vision
  • Increased heart rate
  • Flushing of the face and skin
  • Difficulty swallowing
  • Confusion and agitation

Late Symptoms

As the poisoning progresses, more severe symptoms may develop, such as:

  • Hallucinations and delirium
  • Seizures
  • Muscle weakness and paralysis
  • Irregular heartbeat or arrhythmia
  • Respiratory failure
  • Coma

In severe cases, atropine/belladonna poisoning can be fatal.

Diagnosis and Treatment of Atropine/Belladonna Poisoning


Diagnosing atropine/belladonna poisoning can be challenging, as the symptoms may resemble those of other conditions. A thorough medical history, including any potential exposure to toxic plants or medications, is crucial. Blood and urine tests may be used to detect the presence of atropine or related compounds.


The primary goal of treating atropine/belladonna poisoning is to remove the toxin from the body and manage the symptoms. Treatment options may include:

  • Activated charcoal binds the toxin and prevents further absorption
  • Intravenous fluids to maintain hydration and support kidney function
  • Medications to control symptoms such as seizures, agitation, or irregular heartbeat
  • In some cases, the use of physostigmine, a drug that counteracts the effects of atropine, may be considered

Prompt medical attention is crucial for a positive outcome, and treatment effectiveness depends on the severity of the poisoning and the time elapsed since exposure.

Prevention and Safety Measures

To prevent atropine/belladonna poisoning, consider the following safety measures:

  • Educate yourself and others about the appearance and dangers of belladonna and other toxic plants
  • Keep medications containing atropine out of reach of children and follow the prescribed dosages
  • Be cautious when purchasing herbal supplements or teas, and only buy from reputable sources
  • Teach children not to touch or eat unfamiliar plants or berries


Atropine/belladonna poisoning is a serious condition that can have severe consequences if not promptly diagnosed and treated. Understanding the causes, symptoms, and treatment options is essential for prevention and ensuring a positive outcome in case of exposure. Always be cautious when dealing with potentially toxic plants or substances and seek immediate medical help if you suspect poisoning.
