Before starting to take Vaciclor, the patient should discuss it with their doctor or pharmacist if:

If the patient has any doubts about the above circumstances, they should consult their doctor or pharmacist before starting to take Vaciclor.
Be particularly cautious when taking Vaciclor - important information:
During treatment with valaciclovir, drug reactions known as DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) have been reported, with accompanying eosinophilia and systemic symptoms. DRESS initially resembles flu-like symptoms with a rash on the face, and then manifests as a prolonged 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.
Vaciclor and other medicines
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.

This includes medicines such as aminoglycosides, platinum-based compounds, iodine-based contrast agents, methotrexate, pentamidine, foscarnet, cyclosporine, tacrolimus, cimetidine, and probenecid. If the patient is taking Vaciclor for the treatment of shingles or after organ transplantation, they should always inform their doctor or pharmacist.
Pregnancy and breastfeeding
Valaciclovir is not usually recommended during pregnancy. If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
