Zovirax Intensive cream for topical use contains the active substance aciclovir, which has antiviral properties and is particularly effective against the herpes simplex virus (Herpes simplex).

Warnings and precautions
Before using Zovirax Intensive, the patient should consult a doctor, pharmacist, or nurse if:
- the patient's immune system is not functioning properly (e.g., if the patient has had a bone marrow transplant or has AIDS); patients with impaired immune function should consult a doctor about treating any infection
- the herpes has not cleared up or has worsened after 10 days
- there is a particularly severe recurrence of cold sores
The cream should not be used:
- for skin infections other than herpes
- to treat genital herpes
- on mucous membranes (e.g., eyes, inside the mouth or nose)
Zovirax Intensive should only be used on herpes lesions located on the lips and face.
Contact with the eyes should be avoided.
If the medicine gets into the eyes, they should be rinsed thoroughly with warm water. If in doubt, a doctor should be consulted.
Hands should be washed before and after using the medicine to prevent the spread of infection to other areas of the skin. During treatment, the patient should not scratch or touch the blisters or scabs with a towel.
To minimize the risk of spreading the infection to others, they should not be allowed to touch the herpetic skin lesions, share towels, etc.
Zovirax Intensive and other medicines
The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. Interactions between Zovirax Intensive and other medicines are not known.
Pregnancy, breastfeeding, and fertility
In pregnancy, during breastfeeding, or if the patient is planning to become pregnant, they should consult a doctor or pharmacist before using this medicine.
Driving and using machines
Zovirax Intensive has no or negligible influence on the ability to drive and use machines.
Zovirax Intensive contains propylene glycol, sodium lauryl sulfate, and cetearyl alcohol.
Zovirax Intensive contains 400 mg of propylene glycol per gram of cream.
Due to the presence of the excipient propylene glycol, the medicine may cause skin irritation.
This medicine should not be used in children under 4 weeks of age, on open wounds, or on large areas of damaged or broken skin (e.g., burned skin) without consulting a doctor or pharmacist.
Zovirax Intensive contains 7.5 mg of sodium lauryl sulfate per gram of cream.
Sodium lauryl sulfate may cause local skin irritation (such as stinging or burning) or exacerbate skin reactions caused by other medicines used on the same area of skin.
Patients with impaired skin barrier, such as atopic dermatitis, are more susceptible to the irritating properties of sodium lauryl sulfate.
Due to the presence of the excipient cetearyl alcohol, the medicine may cause a local skin reaction (e.g., contact dermatitis).
3. How to use Zovirax Intensive
This medicine should always be used exactly as described in the package leaflet or as directed by a doctor, pharmacist, or nurse. If in doubt, the patient should consult a doctor, pharmacist, or nurse.

The cream should be applied 5 times a day to the affected areas of the skin at approximately 4-hour intervals, with a night-time break.

If the skin lesions have not healed, treatment can be extended up to 10 days. If the lesions do not clear up after 10 days of using the medicine, the patient should consult a doctor.
