1. What is Fenivir cream and what is it used for

Fenivir contains penciclovir and belongs to a group of medicines called antivirals that slow down the multiplication of viruses, such as the one that causes cold sores.

This virus can remain inactive for long periods of time, but when it becomes active, it starts to multiply and then the lesion develops. This happens, for example, when the defenses are weakened, when you have a cold or flu, or in cases where you have been exposed to strong sunlight. The virus causes painful blisters on the lips.

Fenivir is indicated for the treatment of cold sores (Herpes labialis). When applying Fenivir, it reduces the duration of the pain of the cold sore and accelerates its healing. Additionally, the period during which the cold sore is contagious also decreases, although applying Fenivir does not prevent you from infecting another person.

You should consult a doctor if it worsens or does not improve after 4 days.

You should avoid applying Fenivir inside or around the eyes.

Consult your doctor or pharmacist before using Fenivir:

  • if you are not sure that the lesion is a cold sore;
  • if you have any disease or are receiving any treatment that weakens your immune system (e.g., AIDS, bone marrow transplant, or cancer treatment).

3. How to use Fenivir cream

Follow exactly the administration instructions of this medicine as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

Use the cream as soon as possible after the appearance of the first symptoms (itching and tingling).

However, the cream can be applied when the cold sore has already appeared.

Always wash your hands before and after applying Fenivir. Apply a small amount of product with the tip of your finger to the affected area. Optionally, for packs that contain single-use clean applicators, you can use the applicator instead of your finger if you wish.

Fenivir should be applied every 2 hours during the day (approximately 8 times a day) for 4 consecutive days.

If your symptoms persist or worsen at any time or if you do not observe any improvement after 4 days of treatment, you should consult your doctor.

Use in children

Treatment with Fenivir cream is not recommended in children under 12 years of age.

If you use more Fenivir cream than you should

Although it is unlikely that adverse effects will occur, using an excessive amount of Fenivir in a single application may cause skin irritation.

In case of accidental ingestion, it may cause irritation of the oral mucosa, although no treatment is necessary. Contact your doctor or pharmacist if this happens.

In case of accidental ingestion, consult your doctor or pharmacist immediately, or call the Toxicology Information Service. Phone: 91 562 04 20.

If you forget to use Fenivir cream

Apply the dose as soon as you remember and the next dose at the usual time.

Do not apply a double dose to make up for forgotten doses.

What general precautions should you follow when you have a cold sore

Remember that cold sores are contagious.

To avoid infecting other parts of your body with the virus, as well as infecting other people, it is important that when you have a cold sore:

  • Avoid kissing, especially children.
  • Avoid oral sex.
  • Use your own towels and napkins, and do not share cutlery, glasses, cups, etc.
  • Avoid breaking the blisters or touching the wounds, as this will prolong the healing time.
  • Avoid touching your eyes, as the virus can cause a very serious condition if it reaches the eye.

Do not give this cream to other people, even if their symptoms are the same as yours.

If you have any further questions about the use of this product, ask your doctor or pharmacist.
