thank you for posting your query in healthcaremagic.com..... see first of all what we look for in an herpes infection is the severity or extent of the sores...if it is mild and the symptoms are also not that troublesome, generally antivirals are not needed...but in severe cases, antiviral medicine like ACYCLOVIR or VALACYCLOVIR are prescribed alongwith other medications.... you can do the following- have plenty of oral fluid take tab paracetamol 650/ ibuprofen 400 twice daily if fever or severe pain is present take tab pantroprazole 40 once daily before breakfast if ibuprofen is taken take tab acyclovir/ valacyclovir as specific antiviral medication and yes...acyclovir or valacyclovir is the best antiviral to be advised in herpes attacks... hope this was helpful.... contact me for any further query.... regards
