When to start FAVIPIRAVIR in COVID 19 ?

LikeAnswersShare

FAVIPIRAVIR is indicated in mild to moderate cases of COVID-19 disease. But its efficacy depends upon the timing of start of antiviral. It should be started as early as possible- immediately after patient is tested positive. Any delay in start of antiviral - may not reverse the low perfusion index in lungs . The dose is 1800 mg B.D - first day and 800 mg B.D for 7- 14 days . Now trend is towards 7 days because if at all it benefits- it is the first week of the illness . Mankind company has come 800 mg tab .of FAVIPIRAVIR which is easier to take - then other 200 mg strength tablets available

Thank you doctor
