ACYCLOVIR INF

Acyclovir is an antiviral that blocks herpes viruses from copying themselves. The injectable form is given in hospital when the infection is severe, when it involves the brain or eye, or when the patient cannot take tablets.

What Acyclovir Injection Is Used For

• Severe herpes simplex infection
• Herpes encephalitis, an infection of the brain
• Severe chickenpox or shingles, especially with weakened immunity
• Herpes infection in newborns

Common Side Effects

• Pain or inflammation at the drip site
• Nausea and vomiting
• Headache
• Rise in kidney blood tests

Precautions

Good hydration is important during treatment, because acyclovir can crystallise in the kidneys if fluid intake is low, and the dose is adjusted for kidney function. It is given slowly as an infusion by trained staff. Antivirals work best when started early, so unusual headache, confusion or a rash with severe pain should be assessed quickly.
