Herperax is an antiviral agent. Thymidine kinase of virus-infected cells actively converts Herperax through a series of sequential reactions in the mono-, di- and triphosphate of Herperax. The latter interacts with the viral DNA polymerase, and embedded in DNA, which is synthesized for new viruses. Thus it is formed a "defective" viral DNA which leads to suppression of replication of new generations of viruses.

Using during pregnancy and breastfeeding

Pregnancy. Perhaps, if the expected effect of the therapy outweighs the potential risk to the fetus ; Herperax passes through the placenta. Data on the outcome of pregnancy in women taking Herperax systemic action in the I trimester of pregnancy showed no increase in birth defects compared with the total population. Since the observation was included a small number of women, reliable and definitive conclusions about the safety of Herperax in pregnancy can be done.

Breastfeeding. Herperax penetrates into breast milk. After taking Herperax by mouth, it was determined in breast milk in concentrations, the ratio of which, with concentrations in blood plasma was 0,6-1,4. At these concentrations in breast milk, children who are breastfed can receive Herperax at a dose of 0.3 mg / kg / day. Given this, should appoint Herperax lactating women with caution, only if necessary.

Special instructions

Do not use Herperax with severely impaired renal function.

Note that the application of Herperax may develop acute renal failure due to precipitate formation of crystals of Herperax, which is especially likely during rapid IV introduction, the simultaneous use of nephrotoxic drugs in patients with impaired renal function and lack of water stress.

When applying aciclovir should monitor renal function (determination of the level in the blood urea nitrogen and creatinine in blood plasma).

Treatment of elderly patients should be conducted with a sufficient increase in water load and under the supervision of a physician, because among these patients increased half-life of Herperax.

In the treatment of genital herpes should avoid sex or use condoms, because use of Herperax does not prevent transmission to partners.

This medication Herperax in the form of dosage forms for topical use should not be applied to mucous membranes of the mouth, eyes, vagina.

Herperax drug interactions

With simultaneous use of probenecid decreases the tubular secretion of Herperax, and thereby increases the concentration in blood plasma and the half-life of Herperax.

With simultaneous use of Herperax with other nephrotoxic drugs increases the risk of nephrotoxicity.

Enhancing effect of Herperax is noted while appointing immunostimulators.

When mixed solutions should be considered an alkaline reaction to Herperax for IV introduction (pH 11).
