Correct answer: E — Start now; apply five times daily and avoid the eyes and oral or nasal mucosa

Topical aciclovir should be started as early as possible, including during tingling at the prodromal stage, and is generally applied as a thin layer five times daily about four hours apart. It is not intended for the eye or mucosal application inside the mouth or nose. Waiting, occlusion, hourly use and prolonged post-healing courses do not match the authorised practical instructions.
