1. What is Vaciclor and what is it used for
Vaciclor belongs to a group of medicines called antivirals. It works by killing or inhibiting the growth of herpes simplex virus (HSV), varicella-zoster virus (VZV), and cytomegalovirus (CMV). Vaciclor can be used to:
- treat shingles (in adults)
- treat skin and genital herpes infections caused by the herpes simplex virus (in adults and adolescents over 12 years of age), as well as to prevent recurrence of these infections
- treat cold sores (in adults and adolescents over 12 years of age)
- prevent cytomegalovirus (CMV) infections after organ transplantation (in adults and adolescents over 12 years of age)
- treat and prevent recurrent eye infections caused by the herpes simplex virus (HSV) (in adults and adolescents over 12 years of age).
2. Important information before taking Vaciclor
When not to take Vaciclor
- if the patient is allergic to valaciclovir, acyclovir, or any of the other ingredients of this medicine (listed in section 6).
- if the patient has ever experienced a long-lasting rash associated with fever, lymph node enlargement, elevated liver enzymes, and/or eosinophilia (drug rash with eosinophilia and systemic symptoms) after taking valaciclovir.
Do not take Vaciclor if the above circumstances apply to the patient. In case of doubt, consult the doctor or pharmacist before starting to take Vaciclor.
Warnings and precautions
Before starting to take Vaciclor, discuss it with your doctor or pharmacist if:

- the patient has a weakened immune system
If the patient has any doubts about the above circumstances, they should consult their doctor or pharmacist before starting to take Vaciclor.
Be particularly careful when taking Vaciclor - important information:
During treatment with valaciclovir, drug reactions known as DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) with accompanying eosinophilia and systemic symptoms have been reported. DRESS initially resembles flu-like symptoms with a rash on the face, and then manifests as a long-lasting rash with high body temperature, elevated liver enzymes visible in blood tests, and an increase in white blood cell count (eosinophilia) and lymph node enlargement.
If the patient experiences a rash in combination with fever and lymph node enlargement, they should stop taking valaciclovir and contact their doctor or seek medical help immediately.
Preventing the transmission of genital herpes
If the patient is taking Vaciclor to prevent the transmission of genital herpes or has had such an infection in the past, they should continue to practice safe sex, including the use of condoms. This is important to
prevent the transmission of the infection to others. The patient should not have sexual intercourse if they have ulcers or blisters on their genitals.
