According to sources like the Mayo Clinic, dizziness is listed among the common side effects of digoxin. This means that for some people taking this medication for heart conditions like atrial fibrillation or heart failure, feeling lightheaded or dizzy is a possible reaction, and it is vital to understand the difference between a mild side effect and a symptom of digoxin toxicity.

The incidence of adverse reactions to digoxin has been reported to be between 5% and 20%, with cardiac toxicity accounting for about half of these events [1.7.3]. While often used to slow the heart, a key question remains for patients and clinicians: can digoxin cause tachycardia? The answer is a resounding yes, primarily in the context of toxicity.

In a notable case study, a patient with severe digoxin toxicity exhibited a new right bundle branch block (RBBB) on an electrocardiogram (ECG), confirming that **can digoxin cause bundle branch block** is a possibility, though extremely rare. While not a typical adverse effect, this finding illustrates that excessive digoxin levels can precipitate a variety of serious cardiac conduction abnormalities.

Digoxin, a cardiac glycoside with a narrow therapeutic index, has specific contraindications and risks that must be carefully considered before administration. Due to the fine line between therapeutic and toxic levels, understanding when should not be given digoxin is crucial for patient safety. This article explores the various conditions, drug interactions, and patient factors that prevent or restrict the use of this medication.

Multiple clinical studies have shown that co-administering diltiazem with digoxin can increase digoxin blood levels by 20-50%, creating a significant risk of toxicity. For this reason, anyone asking, 'Can you take diltiazem and digoxin together?' should understand that it is possible but requires vigilant medical oversight.

While once a common treatment, with some estimates suggesting up to 4% of patients on therapy may experience toxicity, digoxin is now reserved for specific situations due to its narrow therapeutic index and risk profile. Understanding when should you not use digoxin is critical for patient safety, requiring careful evaluation of pre-existing conditions, concomitant medications, and overall risk factors.

Several meta-analyses and observational studies have shown that digoxin use is associated with an increased risk of falls, especially in older adults [1.2.2, 1.7.2]. This risk may be higher during the initial treatment period [1.2.1].

Digoxin has a narrow therapeutic index, meaning the difference between a therapeutic dose and a toxic one is small. Understanding what is a cardinal manifestation or symptom of digoxin toxicity is crucial for early detection and preventing severe outcomes.

The incidence of digoxin toxicity is estimated to affect up to 4% of patients on steady therapy, highlighting its narrow safety margin [1.2.1]. To ensure patient safety, it is crucial to understand **what are two contraindications for the use of digoxin?**

Headache is a reported side effect of the cardiac medication digoxin, with an incidence of 1-10% in some reports. While not the most common side effect, headaches can occur and may sometimes signal an elevated level of the drug in the body, which requires immediate medical attention.
