Sofosbuvir duration timeline
Why Sofosbuvir (Hepatitis C Antivirals) is timed this way
Sofosbuvir's duration depends on its half-life, formulation (IR vs ER), and your individual metabolism. Your pharmacist can pull the exact half-life from the FDA label.
Does dose affect how long Sofosbuvir lasts?
For most medications, a higher dose raises peak blood level rather than per-dose duration. Dosing frequency is calibrated to maintain therapeutic blood levels — not extended by taking more at once.
What to do when Sofosbuvir wears off early
If Sofosbuvir appears to wear off before your next dose, talk to your prescriber. Options include dose adjustment, schedule change, or switching to an extended-release form — never adjust your own schedule.
