Aciclovir cream and tablets contain the same antiviral ingredient, but they deliver it differently. Choosing between them requires the location and nature of the infection, not just a price comparison.

Local and oral treatment differ
Cream is applied locally, while tablets are taken orally. Their licensed uses and instructions depend on the exact product. A skin cream is not interchangeable with an eye ointment, and the same ingredient does not make all presentations suitable for the same symptoms.
When assessment matters more than the format
New or severe symptoms, frequent recurrences, pregnancy and a weakened immune system can change the assessment. If there is eye involvement, obtain medical advice instead of applying a skin product around the eye. A catalogue comparison cannot determine the cause of an undiagnosed rash.
Check the preparation and its instructions
Check concentration, formulation, pack quantity and leaflet. Tablets have their own treatment schedules and precautions, including consideration of kidney problems and other medicines. Follow the individual prescription rather than copying an application routine from a cream.
What this comparison can help you ask
Ask whether the diagnosis is confirmed, which form is indicated, when treatment should begin and when lack of improvement needs review. Both forms are listed in the catalogue, but that does not establish that either is appropriate for you or authorised for every destination.
Frequently asked questions
Are tablets simply a stronger cream?
No. Route of administration, indication and treatment plan are different.
Can cold-sore skin cream treat an eye infection?
Do not use a skin cream as an eye medicine. Eye symptoms require appropriate assessment.
Important information
Eye symptoms, severe infection or symptoms in an immunocompromised person should be assessed promptly. Do not substitute cream and tablets without advice.
