1. What Aciclovir Viatris is and what it is used for

Aciclovir Viatris contains aciclovir, an active substance that belongs to a group of medicines called antivirals.

It is indicated for the treatment of mucocutaneous skin infections caused by the herpes simplex virus, including initial genital herpes and its recurrences, as well as cold sores.

2. What you need to know before using Aciclovir Viatris

Do not use Aciclovir Viatris

If you are allergic to aciclovir, valaciclovir, propylene glycol, or any of the other ingredients of this medicine (listed in section 6).

If you think this applies to you, do not use Zovirax cream until you have consulted your doctor.

Warnings and precautions

Talk to your doctor or pharmacist before using Aciclovir Viatris.

Before using this medicine, your doctor needs to know:

  • If you have frequent recurrences, or if you have a condition in which your immune system functions poorly or your body is less able to fight infections (for example, if you have HIV or AIDS, or have received a bone marrow transplant).

Talk to your doctor if you think this applies to you, so they can decide whether you should switch to an oral formulation.

Application of aciclovir on mucous membranes such as in the mouth, eyes, or vagina is not recommended, as it may be irritating. Special care should be taken to avoid accidental contact with the eyes. If accidental contact with the eyes occurs, wash thoroughly with plenty of water and consult an ophthalmologist if necessary.

Genital herpes can be transmitted through sexual contact, even if the partner does not have symptoms. Sexual contact should be avoided if one partner shows signs or symptoms of genital herpes. Aciclovir does not prevent the transmission of herpes.

Do not exceed the recommended frequency of application or the recommended duration of treatment.

Children and adolescents
