Despite no cure or vaccine for the virus, a human body's immune system and specific antibodies typically fight the virus. Docosanol, a saturated fatty alcohol, is a safe and effective topical application that has been approved by the United States Food and Drug Administration for<unk>  in adults with properly functioning immune systems. It is comparable in effectiveness to prescription topical antiviral agents. Due to its mechanism of action, there is little risk of drug resistance. The duration of symptoms can be shortened by a minor amount if an antiviral, anesthetic, zinc oxide or zinc sulfate cream is applied soon after symptoms start. Effective antiviral medications include acyclovir and penciclovir, which can speed healing by as much as 10%. Famciclovir or valacyclovir, taken in pill form, can be effective using a single day, high-dose application and is more cost effective and convenient than the traditional treatment of lower doses for 5–7 days. Mouth-rinse with combinations of ethanol and essential oils against herpes as therapeutic method is recommended by the German Society of Hospital Hygiene. Further research into virucidal effects of essential oils exists.
