What are the manifestations of digitalis drug poisoning?

Digitalis, also known as foxglove, primarily contains active components called cardiac glycosides. Improper use of these substances may often lead to various forms of digitalis poisoning. What are the manifestations of digitalis poisoning?

What Are the Manifestations of Digitalis Poisoning?

1. Improper use of digitalis drugs can cause a series of gastrointestinal reactions, including poor appetite, nausea, vomiting, diarrhea, and abdominal pain.

2. During digitalis therapy, excessive intake may result in arrhythmias. Patients may experience sudden acceleration or slowing of heart rate. After digitalis poisoning, arrhythmias are often accompanied by symptoms such as premature beats and atrial fibrillation.

3. If neurological symptoms such as headache, dizziness, insomnia, forgetfulness, depression, or even mental confusion occur during digitalis treatment, digitalis toxicity should be considered.

4. Following digitalis poisoning, increased release of intracellular potassium ions in the body may lead to hyperkalemia, resulting in visual disturbances such as yellow vision (xanthopsia) or double vision (diplopia).

Once severe digitalis toxicity occurs, patients must immediately discontinue all digitalis medications. If fast arrhythmias occur along with low blood potassium, intravenous potassium supplementation can be administered. If serum potassium levels are normal, lidocaine or phenytoin sodium may be given. For severe bradyarrhythmias, atropine can be administered via intravenous injection, and if necessary, temporary pacemaker insertion may be required.

Digitalis drugs should only be used under medical supervision to avoid adverse outcomes. We hope this information helps you. Wishing you good health and happiness!
