There are no data on the use of higher doses (4000 mg or more per day). At higher doses (4000 mg or more per day), see section "Precautions". Use during pregnancy and lactation Pregnancy. The experience of using valaciclovir in pregnant women is limited, the experience of using acyclovir (the active metabolite of valaciclovir) in pregnant women is not numerous (111 and 1246 patients, respectively, of which 29 and 756 patients took the drug during the first trimester of pregnancy). The use of Valogard VIR during pregnancy is possible if the potential benefit of treatment outweighs the potential risk to the fetus. Lactation. Aciclovir, the main metabolite of valaciclovir, is excreted in breast milk. However, valaciclovir in therapeutic doses does not affect children who are breastfed, because. its amount is less than 2% of the therapeutic dose in the intravenous treatment of neonatal herpes with acyclovir. Valaciclovir should be used with caution during breastfeeding, only if clinically indicated. Fertility. According to animal studies, valaciclovir had no effect on fertility. However, testicular atrophy and aspermatogenesis have been observed with high parenteral doses of acyclovir in rats and dogs. Clinical studies on the effect of valacyclovir on human fertility have not been conducted, however, after 6 months of daily use of acyclovir at a dose of 400 mg to 1 g, no changes in the number, morphology and motility of spermatozoa were observed. PrecautionsHydration. An adequate fluid level should be maintained, which is administered, in patients at increased risk of dehydration, especially in elderly patients. Application for violations of kidney function and in elderly patients. Valaciclovir is excreted by the kidneys, so the dose of valaciclovir should be reduced in patients with impaired renal function (see section "Method of administration and doses"). In elderly patients, renal function is reduced, so they need a dose adjustment. In patients with impaired renal function and in elderly patients, the risk of developing neurological complications is increased, so they are subject to careful medical supervision. The above reactions in most cases are reversible after stopping treatment. There are no data on the use of higher doses (4 g or more per day) of Valogard VIR in liver failure and liver transplantation. Therefore, caution should be exercised when prescribing higher doses of Valogard VIR to such patients. It has been found that prophylaxis with high doses of valaciclovir reduces the incidence of infection and disease caused by cytomegalovirus. In the treatment of herpes zoster, clinical response should be closely monitored, especially in immunocompromised patients. If there is insufficient clinical response to oral therapy, intravenous antiviral therapy should be considered. In severe cases of herpes zoster, i.e. with visceral disease, common herpes, neuropathy, encephalitis, and cerebrovascular complications, intravenous antiviral therapy should be considered. Intravenous antiviral therapy should also be considered in patients with ophthalmic herpes who are immunocompromised or at high risk of disease spread and visceral involvement. Reducing the transmission of the genital herpes virus. Suppressive therapy with valaciclovir reduces the risk of transmission of genital herpes. It does not cure a herpes infection, nor does it completely eliminate the risk of transmission of the virus. In addition to therapy with Valogard VIR, it is recommended that patients follow the rules of safe sex. In the treatment of ophthalmic HSV infections, the clinical response should be closely monitored. If there is insufficient clinical response to oral therapy, intravenous antiviral therapy should be considered. Prevention of cytomegalovirus infection. Valaciclovir should only be used in transplant patients at high risk of CMV disease if safety concerns preclude the use of valganciclovir or ganciclovir. A high dose of valaciclovir may lead to more frequent adverse reactions, incl. CNS disorders. Changes in renal function should be closely monitored and doses adjusted accordingly. Interaction with other drugs Care must be taken when combining valaciclovir with nephrotoxic drugs, especially in patients with impaired renal function, regular monitoring of renal function is recommended. This provision applies to the co-administration of valaciclovir with aminoglycosides, platinum compounds, iodinated contrast agents, methotrexate, pentamidine, foscarnet, cyclosporine, tacrolimus. Aciclovir is excreted mainly unchanged in the urine by active secretion. After taking 1000 mg of valacyclovir, cimetidine and probenecid reduce the renal clearance of acyclovir and increase the AUC of acyclovir by approximately 25% and 45%, respectively, by blocking the tubular secretion of acyclovir. Cimetidine and probenecid, when co-administered with valacyclovir, increase the AUC of acyclovir by approximately 65%. Other drugs (eg, tenofovir) taken concomitantly that compete with or interfere with active tubular secretion may increase aciclovir concentrations through these mechanisms. In addition, valaciclovir may increase plasma concentrations of co-administered agents. In patients with a higher exposure to acyclovir while taking valaciclovir (for example, for the treatment of herpes zoster or the prevention of CMV), caution should be exercised in case of simultaneous use with drugs that inhibit active renal tubular secretion. An increase in the AUC of acyclovir and the inactive metabolite of the immunosuppressive drug mycophenolate mofetil has been noted with the simultaneous use of these drugs in patients after transplantation. No changes in peak concentrations or AUC were observed with the co-administration of valaciclovir and mycophenolate mofetil in healthy volunteers. There is limited clinical experience with this combination. Contraindications Hypersensitivity to the components of the drug and to acyclovir. Composition 1 tablet contains valaciclovir - 500 mg (in the form of valaciclovir hydrochloride - 556 mg); Excipients: microcrystalline cellulose (101), povidone, anhydrous colloidal silicon dioxide, crospovidone, magnesium stearate; shell composition: Sepifilm 050 (methylhydroxypropyl cellulose, microcrystalline cellulose, acetylated (or ester acetates) mono- and diglycerides), kandurin (potassium aluminum silicate (E 555), titanium dioxide (E 171)). Overdose Symptoms. With an overdose of valaciclovir, the development of acute renal failure and neurological symptoms, including confusion, hallucinations, agitation, mental decline and coma, has been reported. Nausea and vomiting may occur. To prevent unintentional overdose, care should be taken when using. Many cases of overdose have been associated with the use of the drug in the treatment of patients with renal insufficiency and elderly patients who have not been dose reduced accordingly. Treatment. Patients should be under close medical supervision to detect signs of toxicity. Hemodialysis significantly accelerates the elimination of acyclovir from the blood and therefore can be considered the best treatment option in case of symptomatic overdose. Side effectsAccording to the frequency of occurrence, adverse reactions are divided into the following categories: very often (?1/10), often (?1/100 and <1/10), infrequently (?1/1000 and <1/100), rarely (?1 /10000 and <1/1000), very rarely (<1/10000). Clinical Trial Data The most common adverse reactions observed in clinical trials were headache and nausea. More serious adverse reactions have included reports of thrombotic thrombocytopenic purpura/hemolytic uremic syndrome, acute renal failure, and neurological impairment. From the nervous system Very often: headache. From the gastrointestinal tract Often: nausea. Post-marketing data From the blood and lymphatic system Infrequently: leukopenia (mainly observed in patients with immunodeficiency), thrombocytopenia. On the part of the immune system Rarely: anaphylaxis. From the nervous system and mental disorders Often: dizziness. Uncommon: confusion, hallucinations, mental decline, agitation, tremor. Rare: ataxia, dysarthria, psychotic symptoms, convulsions, encephalopathy, coma. The above symptoms are in most cases reversible and are observed mainly in patients with renal insufficiency or other predisposing factors (see section "Precautions"). In patients after organ transplantation receiving valaciclovir for the prevention of cytomegalovirus infection in high doses (8 g per day), neurological reactions occur more often than in patients receiving lower doses. On the part of the respiratory system and organs of the chest and mediastinum Infrequently: shortness of breath. From the digestive tract Often: vomiting, diarrhea. Uncommon: abdominal discomfort. On the part of the hepatobiliary system Infrequently: a reversible increase in the level of hepatic functional tests. It is periodically described as hepatitis. On the part of the skin and subcutaneous tissues Often: rash, including photosensitivity phenomena, itching. Uncommon: urticaria. Rare: angioedema. From the side of the kidneys and urinary system Infrequently: pain in the kidneys (may be associated with renal failure), hematuria (often associated with other renal dysfunction). Rarely: impaired renal function, acute renal failure. The formation of precipitates of acyclovir in the tubules of the kidneys has been reported. During treatment, an adequate level of fluid intake should be ensured (see section "Precautions"). Others: There have been reports of renal failure, microangiopathic hemolytic anemia and thrombocytopenia (sometimes in combination) in severely immunocompromised patients, especially in patients with advanced HIV disease, who received high doses (8000 mg per day) of valaciclovir for a long time in clinical research. These phenomena have been seen in patients with the same disease who were not treated with val acyclovir. If you experience any of these or any other adverse reactions not listed in this leaflet, you should consult a doctor.
