Acyclovir Side Effects

Acyclovir side effects can be split into two categories:

Common Side Effects (less than 5%):

• diarrhea
• general discomfort or feeling of illness (high doses)
• headache
• itching (ointment)
• nausea
• skin rash or discomfort (usually ointment)

Treatment with Acyclovir ointment is unlikely to produce systemic side effects, as it is poorly absorbed through the skin.

Rare Side Effects:

• Anaphylactic (acute allergic) reaction
• aggression
• agitation
• altered vision
• anemia
• bloody urine
• coma
• confusion
• delirium
• dizziness
• drowsiness
• fever
• hair loss
• hallucinations
• hives
• kidney failure
• psychosis
• seizures
• skin peeling
• light sensitive rash
• swelling in the extremities
• swollen lymph nodes
• tremors
• yellowed skin and eyes (indicative of serious liver problems)

If any of these symptoms occur, contact your doctor or a hospital immediately, and go in for an examination. Particularly severe symptoms may require emergency medical services.
