Special instructions:

Prolonged or repeated treatment with Valtrex patients with low immunity could lead to strains of viruses, sensitive to its effects. The majority of selected strains of viruses, insensitive to azikloviru encounters a relative lack of viral timidinkinaza virus; There were strains with modified timidinkinazoy or with altered DNA polymerase. In vitro effect of Valtrex on isolated strains of Herpes simplex virus can cause less sensitive strains.
Adequate and well-controlled clinical studies safety of the drug during pregnancy is not held. Use is shown only in cases where the presumed benefit to the mother outweighs the potential risk to the fetus.
During therapy high oral doses of drugs should ensure adequate intake of fluids in the organism of the patient.
If necessary, the appointment of the drug during lactation should stop breastfeeding.
Valtrex does not prevents transmission of herpes infections during treatment should therefore abstain from sexual contact, even in the absence of clinical manifestations.

Interaction:
When mixing solutions must take into account the alkaline reaction of Valtrex for the on/in the introduction (pH 11).
Enhancing effect noted while appointing immunostimulators.
Blockers reduce kanalzeva secreta kanalzevu secretion in/typed Valtrex, which can lead to increased concentrations of Valtrex in the serum and CSF, slow excretion aziklovira (increase in the T1/2) of blood and CSF, enhance toxicity.
Etc. nefrotoksicskie HP-increased risk of nefrotoksicski action.
