Digoxin and LAE

She used to take digoxin 0.25 mg for persistent atrial fibrillation. Doctor suddenly reduced the dosage to half stating the age has reached 60. After that, her LAE has been increasing unlike before. It is over 5cm( less than 5cm previously) permanently. Whether the digoxin level can be changed to full tablet again?

Hello, I went through your query, this dioxin has very narrow therapeutic index in the blood, that means even very slight increase in blood levels, can have more harmful effect on heart than beneficial effect and it's dose should be decreased as the person ages. Since she is not benefitting from the current dose,, dose can be increased with close monitoring of blood levels please consult cardiologist.
