Acute poisoning caused by excessive doses often causes palpitations, cold limbs, low blood pressure, and even shock. Patients also experience difficulty breathing, pupil constriction, coma, and loss of reflexes. Protein, red and white blood cells and casts may appear in the urine. Long-term, high-dose use can cause granulocytopenia, thrombocytopenia, hemolytic anemia, and even aplastic anemia. Facial nerve paralysis, dysarthria and stuttering, spasms of the muscles around the eye sockets, and even opisthotonos may also occur. A few cause eye damage, leading to vision loss or even blindness.

4. Digitalis poisoning

Digitalis drugs are mainly used to treat congestive heart failure, but their therapeutic dose is very close to the toxic dose. The elderly have poor tolerance and are very prone to poisoning. When poisoned by digitalis, patients experience headaches, dizziness, blurred vision, yellow vision, anorexia, nausea, vomiting, diarrhea, and various heart rhythm abnormalities such as premature ventricular contractions, paroxysmal atrial tachycardia, and atrioventricular conduction block. Some patients who originally had atrial fibrillation suddenly had a regular heart rhythm and the electrocardiogram showed a typical digitalis poisoning pattern.
