Acids and bases in the Brnsted model therefore exist as conjugate pairs whose formulas are related by the gain or loss of a hydrogen ion. Our use of the symbols HA and A- for a conjugate acid-base pair does not mean that all acids are neutral molecules or that all bases are negative ions. It signifies only that the acid contains an H+ ion that isn't present in the conjugate base.
Zovirax Ointment. Zovirax is a brand name for a prescription ointment cream that contains the anti-viral medication acyclovir. This medicated ointment is commonly used to treat genital herpes and cold sores in the mouth.
For shingles or chickenpox, start taking valacyclovir at the first symptom or as soon as possible after the rash appears.
