What are Valtrex drugs given for?

Valtrex®

This medicine has been prescribed for you by your doctor to treat your current illness.

The antivirals in Valtrex are not effective against all microorganisms that cause infectious diseases. The use of an incorrectly selected or incorrectly dosed virostat can cause complications. Therefore, never use it on your own for the treatment of other illnesses or other people.

Please ensure that you are drinking enough fluids while you are being treated with Valtrex.

Valtrex must not be used if there is a known hypersensitivity to the active ingredient of Valtrex and Zovirax (acyclovir) or to the excipients in the two tablet forms.


If there is a known kidney dysfunction, this must be reported to the doctor, as the dosage may need to be adjusted.

Effective contraception should be used in women of childbearing potential before long-term treatment is started.

In the absence of experience, Valtrex should not be used in children under 12 years of age.

Due to possible side effects, caution should be exercised when driving vehicles and using machines.

Inform your doctor or pharmacist if you suffer from other illnesses, have allergies or are taking or using other medicines (including those you have bought yourself!).


You may only take Valtrex during pregnancy and breastfeeding if your doctor tells you to.

Breastfeeding should not be performed while taking Valtrex.
