Zovirax Liquid, also known as Zovirax Suspension or Acyclovir Suspension, is an oral formulation of the antiviral medication acyclovir. It is mainly used for treating herpes simplex virus infections of the skin and mucous membranes, including initial and recurrent episodes. 

Use and Dosage 

Zovirax Liquid is an oral medication that should be taken by mouth, with or without food, as directed by your doctor. Drink plenty of fluids while taking the liquid to prevent dehydration. Make sure to follow the dosage instructions provided by your healthcare provider to ensure proper use of the medication. 

Shake the bottle well before each use to ensure proper mixing of the medication. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. 

If you miss a dose of Zovirax Liquid, take it as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
