Yes. Canesten's fine for DH (or any generic anti-fungal cream like clotrimazole, which is the active ingredient in canesten). Twice a day for at least 4 weeks (with men fungal spores can stay underneath the skin surface for longer). If he prefers use canesten for a week then use the lamisil once cream (you need to only apply this once. It will remain in his skin for 4 weeks). However, canesten is preferable.
