Scottish Medicines Consortium (SMC) decisions
The Scottish Medicines Consortium has advised (October
2011) that vardenafil orodispersible tablets (Levitra ®) are
accepted for restricted use within NHS Scotland for
treatment of erectile dysfunction in men for whom an
orodispersible tablet is an appropriate formulation.
NHS restrictions Levitra ® is not prescribable in NHS
primary care for the treatment of erectile dysfunction
except in men who meet the criteria listed in part XVIIIB of
the Drug Tariff (Part XIb of the Northern Ireland Drug
Tariff, Part 12 of the Scottish Drug Tariff). The prescription
must be endorsed ’SLS’. For more information see Prices in
the BNF, under How to use the BNF.
