Digoxin toxicity is commonly associated with a range of clinical symptoms due to its effects on the heart and the central nervous system. Common symptoms include confusion and cognitive disturbances, which occur due to the drug's impact on the brain. An irregular pulse can manifest because digoxin affects cardiac conduction and can lead to arrhythmias; this includes both bradycardia and various types of heart rhythm disturbances.

Nausea is another classic symptom of digoxin toxicity, often related to gastrointestinal disturbances that can occur when drug levels are elevated beyond therapeutic ranges.

Excessive daytime urination, however, is not typically a symptom associated with digoxin toxicity. While changes in urination can occur due to numerous factors, including renal function or other medications, it is not a direct symptom linked to the toxic effects of digoxin. Thus, choosing excessive daytime urination as the symptom not associated with digoxin toxicity is justified based on the typical clinical presentations observed in cases of digoxin toxicity.
