Take care when prescribing and dispensing Digoxin has a low therapeutic index so cautious dose determination is essential and individual patient factors must be considered during formulation changes. Patient levels should be monitored appropriately. The bioavailability of orally administered digoxin is approximately 63% in tablet form and 75% as the oral solution. This equates to ONE 62.5 microgram tablet being approximately equivalent to 50 micrograms (1 ml) elixir. However, the manufacturer is aware of one study showing no clinically relevant difference in bioavailability of digoxin tablets and elixir and suggests that these dosage forms can usually be used interchangeably.[SPS (2018)]

Dose titration necessary: The recommended initial dose is 375 mg twice daily. After 2–4 weeks, the dose should be titrated to 500 mg twice daily and, according to the patient's response, further titrated to a recommended maximum dose of 750 mg twice daily. If patient experiences treatment-related adverse events (e.g. dizziness, nausea, or vomiting), down-titration to 500 mg or 375 mg twice daily may be required.
