Sara Errani got a 10-month doping ban from the Court of Arbitration for Sport (CAS) Monday which upped her existing two-month ban for using a banned substance.
The Italian tennis player tested positive for aromatase inhibitor letrozole last August.
Italy's National Anti-Doping Agency (NADO) appealed to extend the two-month ban, adjudging it too mild.
With two months already served, the ban now runs from June 8 to February 8 2019.
Errani will also have to pay 4,000 Swiss francs to NADO.
She loses the points from all the results obtained since she came back.
