Contraindications When Aciclin should not be used
Aciclovir tablets and suspension are contraindicated in patients with known hypersensitivity to aciclovir and valaciclovir or to any of the excipients.
Cream:
Aciclovir cream is contraindicated in patients with known hypersensitivity to aciclovir, valaciclovir, propylene glycol or to any of the excipients of aciclovir cream. Generally contraindicated in pregnancy and lactation (see SPECIAL WARNINGS).
Precautions for use What you need to know before taking Aciclin
Children, Elderly, Patients with specific clinical pictures See "DOSE, METHOD AND TIME OF ADMINISTRATION".
Interactions Which drugs or foods can modify the effect of Aciclin
Tell your doctor or pharmacist if you have recently taken any other medicines, even those without a prescription.
Tablets, suspension and granules:
No clinically significant interactions have been identified. Aciclovir is excreted primarily unchanged in the urine via active renal tubular secretion. Any concomitantly administered drug that competes with this mechanism of action may increase the plasma concentrations of aciclovir. Probenecid and cimetidine increase the area under the curve for aciclovir through this mechanism, and reduce the renal clearance of aciclovir. Increases in the area under the curve in plasma concentrations of aciclovir and the inactive metabolite of mofetil have been shown. mycophenolate, an immunosuppressive substance used in transplant patients, when these drugs are co-administered. However, no dosage adjustments are necessary due to the broad therapeutic index of aciclovir.
Cream:
No clinically significant interactions have been identified.
Warnings It is important to know that:
Pregnancy
Ask your doctor or pharmacist for advice before taking any medicine.
Tablets, suspension and granules:
Since clinical data on administration in pregnancy are limited, during this period the drug should only be administered in cases of absolute necessity under direct medical supervision, when the potential benefits outweigh the possibility of unknown risks.
Cream:
The use of aciclovir should only be considered if the potential benefits outweigh the possibility of unknown risks, however the systemic exposure of aciclovir following topical application of aciclovir cream is very low.
A registry of post-marketing use of aciclovir in pregnancy provided data on pregnancy outcomes in women exposed to the various aciclovir formulations.
These observations did not show an increase in the number of birth defects among acyclovir-exposed subjects compared to the general population, and all birth defects found did not show any particularities or common characteristics that would suggest a single cause.
Systemic administration of Aciclovir in internationally accepted standard tests did not produce embryotoxic or teratogenic effects in rabbits, rats or mice.
In a non-standard rat test, fetal abnormalities were observed after subcutaneous doses of Aciclovir so high that they produced toxic effects on the mother. The clinical relevance of these findings is uncertain.
Feeding time
Tablets, suspension and granules:
Following oral administration of Aciclovir 200 mg, 5 times / day, the presence of Aciclovir in breast milk was observed at concentrations equal to 0.6-4.1 times the corresponding plasma levels. Such levels would potentially expose infants to Aciclovir doses up to 0.3 mg / kg / day. Therefore, the use of Aciclovir during breastfeeding should be avoided.
Cream:
Limited data indicate that the drug is found in breast milk following systemic administration. However, the dose received by an infant following the use of aciclovir cream in the mother should be insignificant.
Important information about some of the excipients
Due to the presence of aspartame, the granules formulation for oral suspension is not indicated in patients with phenylketonuria.
Each sachet of granules for oral suspension contains 1.8 g of sucrose and therefore this formulation is not suitable for subjects with hereditary fructose intolerance, glucose and galactose malabsorption syndrome or sucrase-isomaltase deficiency.
The oral suspension formulation contains glycerol: harmful in high doses; it can cause migraines, stomach upset and diarrhea.
A 10 ml dose of oral suspension contains not less than 2.6 g of sorbitol and therefore this formulation is not suitable for subjects with hereditary fructose intolerance; it can cause stomach upset and diarrhea.
Tablets, suspension and granules: Use in patients with renal insufficiency and elderly patients
Aciclovir is eliminated by renal clearance, therefore the dose should be reduced in patients with renal insufficiency (see Dose, method and time of administration). Elderly patients are likely to have impaired renal function and therefore the need for dose reduction should be considered in this patient group. Both elderly patients and patients with renal insufficiency are at increased risk of developing neurological side effects and should be carefully monitored for these effects. In reported reports, these reactions were generally reversible upon discontinuation of treatment (see Undesirable Effects). Prolonged or repeated courses of aciclovir in severely immunocompromised patients may be associated with the selection of viral strains with reduced sensitivity, which may not respond to continued aciclovir treatment. Hydration status: Ensure adequate hydration is maintained in patients taking high doses of oral aciclovir.
Cream
The product is not for ophthalmic use, nor is it recommended for application on mucous membranes, such as in the mouth, eye or vagina, as it can cause irritation. Particular care should be taken to avoid accidental application to the eye. In severely immunocompromised patients (eg AIDS patients or bone marrow transplant patients) administration of aciclovir in oral formulations should be considered. It should be recommended that such patients be consult your doctor about the treatment of any infection.
Important information about some of the excipients
The propylene glycol excipient can cause skin irritation.
Effects on ability to drive and use machines
The clinical condition of the patient and the adverse event profile of aciclovir should be taken into account with regard to the patient's ability to drive and use machines. No studies have been performed to investigate the effects of aciclovir on the ability to drive and operate machinery. Further harmful effects on these activities cannot be predicted from the pharmacology of the active ingredient.
Dosage and method of use How to use Aciclin: Dosage
Tablets, suspension and granules
A measuring cup with indicated level marks corresponding to the capacity of 5 and 10 ml is attached to the package of Aciclovir in suspension.
Shake the suspension before use.
Granules: dissolve the contents of one sachet in half a glass of water and shake the suspension.
Adults
Treatment of Herpes Simplex infections
One 200 mg tablet 5 times a day, at intervals of approximately 4 hours, omitting the night dose. Treatment should be continued for 5 days, but prolongation may be necessary in cases of severe primary infections.
In patients with severely impaired immune function (eg, after a bone marrow transplant) or in patients with impaired intestinal absorption, the dosage can be doubled to 400 mg or 5 ml suspension, or alternatively, the appropriateness of to use an intravenous injectable formulation of Aciclovir.
Therapy should be started as soon as possible, and in the case of recurrent infections, preferably at the first symptoms or when the first lesions appear.
Suppressive therapy of relapse of Herpes Simplex infections in patients with normal immune function
One 200 mg tablet 4 times a day, at 6 hour intervals. Many patients can be successfully treated by administering 400 mg tablets or 5 ml suspension twice daily, at 12 hour intervals. Dosages of 200 mg 3 times a day, at 8-hour intervals, or 2 times a day at 12-hour intervals, may also be effective. Relapses of infection may occur in some patients with a total daily dose of 800 mg of ACICLOVIR.
Therapy should be interrupted periodically at intervals of 6 to 12 months, in order to observe any changes in the natural history of the disease.
Prophylaxis of Herpes Simplex infections in patients with impaired immune function
One 200 mg tablet 4 times a day, at 6 hour intervals. In patients with severely impaired immune function (for example, after a bone marrow transplant) or in patients with impaired intestinal absorption, the dosage can be doubled to 400 mg in tablets or 5 ml suspension, or alternatively, it can be evaluated. the opportunity to use an intravenous injectable formulation of Aciclovir.
The duration of prophylaxis must be considered in relation to that of the risk period.
Treatment of Herpes Zoster infections and chickenpox
800 mg (1 tablet or 1 sachet or 10 ml suspension) 5 times a day, at intervals of approximately 4 hours, omitting the night dose.
Treatment should be continued for 7 days. In patients with impaired immune function (eg after a bone marrow transplant) or in patients with impaired intestinal absorption, intravenous administration of injectable aciclovir may be considered. "infection, in fact the treatment obtains better results if established at the appearance of the first lesions.
Children
For the treatment of Herpes Simplex infections and for their prophylaxis in immunocompromised children over 2 years of age, the dosage is similar to that of adults. Under 2 years the dosage is reduced by half.
For the treatment of chickenpox in children over 6 years of age, the dosage is 800 mg (1 tablet or 1 sachet or 10 ml suspension) 4 times a day; in those aged between 2-6 years the dosage is 400 mg in tablets or 5 ml of suspension 4 times a day; in those younger than 2 years the recommended dosage is 200 mg (2.5 ml of suspension) 4 times a day.
The administration of 20 mg / kg of body weight (not exceeding 800 mg) 4 times a day, allows a more precise dosage adjustment. Treatment should be continued for 5 days.
No specific data are available on the suppression of Herpes simplex infections or the treatment of Herpes Zoster in children with normal immune function.
For the treatment of Herpes Zoster in children with impaired immune function, consideration should be given to using an intravenous formulation of Aciclovir for injection.
Senior citizens
In the elderly, the total elimination of Aciclovir decreases with decreasing certain renal function indices associated with advancing age. In patients taking high doses of Aciclovir orally, adequate fluid intake should be maintained. Particular attention should be paid to evaluating the possibility of a reduction in dosage in the case of elderly patients with impaired renal function.
Subjects with renal impairment
In the treatment of Herpes simplex infections, in patients with severe renal impairment (creatinine clearance less than 10 ml / min), it is recommended to adjust the dose to: - 200 mg, administered twice daily at approximately 12 hour intervals. In the treatment of chickenpox and herpes zoster, it is recommended that the dosage be changed to:
Cream
Aciclovir cream should be applied 5 times a day, at intervals of approximately 4 hours. Aciclovir cream should be applied to lesions, or areas where they are developing, as early as possible after the infection begins. It is especially important to start treatment for recurrent episodes during the prodrome phase or at the first appearance of lesions. Treatment must continue for at least 5 days and up to a maximum of 10 if there is no healing.
Overdose What to do if you have taken an overdose of Aciclin
In case of accidental ingestion / intake of an excessive dose of ACICLIN, notify your doctor immediately or go to the nearest hospital.
If you have any questions about the use of ACICLIN, ask your doctor or pharmacist.
Tablets, suspension and granules:
Signs and symptoms
Aciclovir is only partially absorbed from the intestine. Patients who have ingested an overdose of up to 20 g of aciclovir in a single dose have generally not experienced toxic effects.
Accidental and repeated overdoses of oral aciclovir over several days have been associated with gastrointestinal effects (such as nausea and vomiting) and neurological effects (headache and confusion).
Overdose of intravenous aciclovir resulted in increased serum creatinine, blood urea nitrogen and subsequent renal failure. Neurological effects including confusion, hallucinations, agitation, convulsions and coma have been reported in conjunction with overdose.
Treatment
Patients should be carefully observed for any signs of toxicity.
Hemodialysis significantly increases the elimination of aciclovir from the blood can therefore be considered an option in the management of drug overdose.
Cream: Even if the entire contents of a tube of cream containing 500 mg of acyclovir are ingested, no undesirable effects should be expected.
Side Effects What are the side effects of Aciclin
Like all medicines, this can cause side effects, although not everybody gets them.

Cream :
Aciclovir cream is contraindicated in patients with known hypersensitivity to aciclovir, valaciclovir, propylene glycol or to any of the excipients of aciclovir cream.
Generally contraindicated in pregnancy and lactation (see section 4.6).
04.4 Special warnings and appropriate precautions for use -
Children, Elderly, Patients with specific clinical pictures: see "Posology and method of administration".
Due to the presence of aspartame, the formulation granules for oral suspension it is not indicated in patients with phenylketonuria.
Each sachet of granules for oral suspension contains 1.8 g of sucrose and therefore this formulation is not suitable for subjects with hereditary fructose intolerance, glucose and galactose malabsorption syndrome or sucrase-isomaltase deficiency.
The wording oral suspension contains glycerol: harmful in high doses; it can cause migraines, stomach upset and diarrhea.
A 10 ml dose of oral suspension it contains 2.6 g of sorbitol and therefore this formulation is not suitable for subjects with hereditary fructose intolerance; it can cause stomach upset and diarrhea.
Shake the suspension before use.
Tablets, suspension and granules:
Use in patients with renal insufficiency and elderly patients:
Aciclovir is eliminated by renal clearance, therefore the dose should be reduced in patients with renal insufficiency (see section 4.2). Elderly patients are likely to have impaired renal function and therefore the need for dose reduction in this patient group should be considered. Both elderly patients and patients with renal insufficiency have an increased risk of developing neurological side effects and should be carefully monitored for these effects. In reported reports these reactions were generally reversible upon discontinuation of treatment (see section 4.8).
Prolonged or repeated courses of aciclovir in severely immunocompromised patients may lead to a selection of viral strains with reduced sensitivity, which may not respond to continuous courses of aciclovir treatment (see section 5.1).
Hydration Status: Ensure adequate hydration is maintained in patients taking high doses of oral aciclovir.
Cream
The product is not for ophthalmic use, nor is it recommended for application on mucous membranes, such as in the mouth, eye or vagina, as it can cause irritation. Particular care should be taken to avoid accidental application into the eye.
In severely immunocompromised patients (e.g. AIDS patients or bone marrow transplant patients) administration of aciclovir in oral formulations should be considered. Such patients should be recommended to consult their physician regarding the treatment of any infection.
The propylene glycol excipient can cause skin irritation.
Animal studies indicate that the application of Aciclovir cream into the vagina may cause reversible irritation.
The use of the product, especially if prolonged, can give rise to sensitization phenomena, where this happens it is necessary to stop the treatment and consult the attending physician.
04.5 Interactions with other medicinal products and other forms of interaction -
Tablets, suspension and granules:
No clinically significant interactions have been identified.
Aciclovir is excreted primarily unchanged in the urine via active renal tubular secretion. Any concomitantly administered drug that competes with this mechanism of action may increase the plasma concentrations of aciclovir. Probenecid and cimetidine increase the area under the curve for aciclovir through this mechanism, and reduce the renal clearance of aciclovir. Increases in the area under the curve in plasma concentrations of aciclovir and the inactive metabolite of mofetil have been shown. mycophenolate, an immunosuppressive substance used in transplant patients, when these drugs are co-administered. However, no dosage adjustments are necessary due to the broad therapeutic index of aciclovir.
Cream
No clinically significant interactions have been identified.
04.6 Pregnancy and breastfeeding -
Fertility
There are no data on fertility in women. Aciclovir tablets have not been shown to affect sperm count, morphology and motility in humans (see also section 5.3).
Pregnancy
Tablets, suspension and granules:
Since clinical data on administration in pregnancy are limited, during this period the drug should only be administered in cases of absolute necessity under direct medical supervision, when the potential benefits outweigh the possibility of unknown risks.
Cream:
The use of aciclovir should only be considered if the potential benefits outweigh the possibility of unknown risks, however the systemic exposure of aciclovir following topical application of aciclovir cream is very low.
A registry of post-marketing use of aciclovir in pregnancy provided data on pregnancy outcomes in women exposed to the various aciclovir formulations. These observations did not show an increase in the number of birth defects among subjects exposed to aciclovir in compared to the general population, and all the defects found at birth did not show any particularity or common characteristics, such as to suggest a single cause.
Systemic administration of Aciclovir in internationally accepted standard tests did not produce embryotoxic or teratogenic effects in rabbits, rats or mice.
In a non-standard rat test, fetal abnormalities were observed after subcutaneous doses of Aciclovir so high that they produced toxic effects on the mother. The clinical relevance of these findings is uncertain.
Feeding time
Tablets, suspension and granules:
Following oral administration of Aciclovir 200 mg, 5 times / day, the presence of Aciclovir in breast milk was observed at concentrations equal to 0.6-4.1 times the corresponding plasma levels. Such levels would potentially expose infants to Aciclovir doses up to 0.3 mg / kg / day. Therefore, the use of Aciclovir during breastfeeding should be avoided.
Cream:
Limited data indicate that the drug is found in breast milk following systemic administration. However, the dose received by an infant following the use of aciclovir cream in the mother should be insignificant.
04.7 Effects on ability to drive and use machines -
Tablets, suspension and granules:
The clinical condition of the patient and the adverse event profile of aciclovir should be taken into account with regard to the patient's ability to drive and use machines.

Rare: erythema. Contact dermatitis after application. Where sensitivity tests were conducted, it was shown that the substances that gave phenomena of reactivity were the components of the base cream rather than acyclovir.
Disorders of the immune system
Very rare: immediate hypersensitivity reactions including angioedema and urticaria.
04.9 Overdose -
Tablets, suspension and granules:
Signs and symptoms
Aciclovir is only partially absorbed from the gut. Patients who have ingested an overdose of up to 20 g of aciclovir in a single dose generally have no toxic effects. Accidental and repeated overdoses of oral aciclovir over several days are reported. states associated with gastrointestinal effects (such as nausea and vomiting) and neurological effects (headache and confusion).
Overdose of intravenous aciclovir has resulted in increased serum creatinine, blood urea nitrogen and subsequent renal failure. Neurological effects including confusion, hallucinations, agitation, convulsions and coma have been reported in conjunction with overdose.
Treatment
Patients should be carefully observed for any signs of toxicity. Hemodialysis significantly increases the elimination of aciclovir from the blood and can therefore be considered an option in the management of drug overdose.
Cream: Even if the entire contents of a tube of cream containing 500 mg of acyclovir are ingested, no undesirable effects should be expected.
05.0 PHARMACOLOGICAL PROPERTIES -
05.1 "Pharmacodynamic properties -
Pharmacotherapeutic group: Antivirals for systemic use, J05AB1 (Tablets, suspension and granules)
Pharmacotherapeutic group: Topical chemotherapeutic agents - antivirals; D06BB03 (Cream)
Aciclovir is a synthetic purine nucleoside analog with inhibitory activity, in vitro and in vivo, against human herpetic viruses, including the Herpes Simplex virus (HSV) type 1 and 2 and the Varicella Zoster virus (VZV). In cultures cellular, Aciclovir showed the greatest antiviral activity against HSV-1, followed by HSV-2.
The inhibitory activity of Aciclovir against HSV-1 and HSV-2 is highly selective.
The thymidine kinase enzyme of normal, uninfected cells does not effectively use Acyclovir as a substrate; therefore the toxicity for the host cells is low; on the contrary, viral thymidine kinase converts Aciclovir into Aciclovir monophosphate, a nucleoside analogue, which is further converted into di-phosphate and tri-phosphate by cellular enzymes. Aciclovir tri-phosphate interferes with viral DNA polymerase and inhibits viral DNA replication; its incorporation into the viral DNA causes the interruption of the catenary elongation process of the latter.
Prolonged or repeated courses of Aciclovir in severely immunocompromised patients may be associated with the selection of viral strains with reduced sensitivity, which may not respond to continued treatment with Aciclovir.
Most of the isolated viral strains, with reduced sensitivity, showed a relative deficiency of viral thymidine kinase; however, strains with altered viral thymidine kinase or DNA polymerase have also been observed. In vitro exposure of isolated HSV strains to Aciclovir may also be associated with the appearance of less sensitive strains. The relationship between the sensitivity, determined in vitro, of isolated HSV strains and the clinical response to Aciclovir therapy , is not clarified.
05.2 "Pharmacokinetic properties -
Aciclovir is only partially absorbed from the intestine.
Peak steady state plasma concentrations (Cssmax) after doses of 200 mg every 4 hours is 3.1 mcMol (0.7 mcg / ml) and the trough concentration (Cssmin) is 1.8 mcMol (0.4 mcg / ml).
After doses of 400 mg and 800 mg every 4 hours the Cssmax is, respectively, 5.3 mcMol (1.2 mcg / ml) and 8 mcMol (1.8 mcg / ml) and the Cssmin is, respectively, 2.7 mcMol (0.6 mcg / ml) and 4 mcMol (0.9 mcg / ml).
From studies with aciclovir administered intravenously, the half-life of the drug is approximately 2.9 hours. Most of the drug is excreted unchanged via the kidney. The renal clearance of Aciclovir is considerably greater than that of creatinine, indicating that in addition to glomerular filtration contributes to the renal elimination of the drug tubular secretion. The only important metabolite is 9-carboxymethoxymethylguanine corresponding to approximately 10-15% of the urinary excreted dose.
In the elderly, total clearance decreases with increasing age along with creatinine clearance, however there are slight changes in the terminal plasma half-life.
In patients with chronic renal insufficiency, the mean half-life is 19.5 hours while during hemodialysis the mean half-life of Aciclovir is 5.7 hours and the levels are reduced by an average of about 60%.
The drug levels in the CSF are approximately 50% of the plasma levels. Plasma protein binding is relatively poor (9 to 33%) and drug interactions due to binding site displacement are not expected.
05.3 Preclinical safety data -
Mutagenicity
The results of a large number of in vitro and in vivo mutagenicity tests indicate that Aciclovir does not pose genetic risks for humans.
Carcinogenesis
In long-term studies in rats and mice, Acyclovir was not found to be carcinogenic.
Fertility
Reversible toxic effects on spermatogenesis have been reported in rats and dogs only at doses significantly higher than therapeutic ones. Two-generation studies in mice revealed no effects of aciclovir, administered orally, on fertility.
