The high new Rx% might be an aberration, but it could also likely be a result of the NEJM article that came out December 20th that put tyzeka in the front of some people's minds and the affect is starting to trickle down to new Rx.

Will be interesting to look for follow though in the next couple of weeks.

Tyzeka US Scripts

Jan11 numbers retreated from the prior week, and it
remains to be seen if the Jan04 numbers were the start
of a trend or an aberration. Please see separate post
for rolling four-week scripts. (Data c/o rkrw.)

NRx=number of new prescriptions; TRx=number
of total prescriptions (new+renewal). For recently
launched drugs, the trend in NRx is an indicator of
what can be expected for TRx with a modest time lag.
NRx% and TRx% are calculated as NRx and TRx
divided by the number of new and total prescriptions,
respectively, for all drugs in the HBV category. (A
prescription is counted as new whenever it is newly
written, even if the patient is already taking the drug.)
