Take Zovirax as soon as a herpes outbreak appears with a full glass of water.  Drink plenty of water while taking Zovirax to help your kidneys function properly.  Zovirax can be taken with or without food.  For Zovirax liquid, shake the suspension well before you measure a dose.  Be sure you measure the correct dose.  With Zovirax topical, follow the application directions on the label carefully.  Lesions should be kept as clean and dry as possible.  Wearing loose clothing may help prevent the irritation of herpes virus lesions.

What precautions should I follow when taking Zovirax /Acyclovir ?

Herpes infections are contagious.  You can infect others with herpes even while you are being treated with antiviral medication.  Avoid letting infected areas come into contact with other people.  Avoid touching the infected area and then touching your eyes.  Wash your hands frequently to prevent passing the infection on to others.  Zovirax will not prevent the spread of genital herpes.  Make sure to avoid sexual intercourse or use a latex condom to prevent passing the virus on to others.
