4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

These side effects are classified from the most frequent to the least frequent.

Common:(may affect up to 1 in 10 people)

• Gastrointestinal problems:

• nausea,
• vomiting,
• diarrhea,
• abdominal pain.

• Liver problems:increased bilirubin and liver enzymes (substances produced by the liver) in the blood.

These effects usually disappear when treatment is discontinued.

• Skin reactions:
• • pruritus (itching)
  • rash
  • urticaria (rash identical to that caused by nettle stings).
• Kidney problems:increased urea and creatinine in the blood (sign of kidney function problems).
• General problems:inflammatory skin lesions or phlebitis (formation of a blood clot in a vein) at the injection site, which can cause necrosis (cell destruction) in exceptional cases of extravasation (when the medicine leaks out of the vein it was injected into) or insufficient dilution of the solution. These inflammatory lesions are related to the alkaline pH of this medicine.

Frequency not known:(frequency cannot be estimated from the available data)

• Blood problems:

• thrombocytopenia (decreased platelet count)
• leukopenia (decreased white blood cell count).

• Neuropsychiatric problems:

• headache, dizziness.
• balance problems, ataxia (problems walking and lack of coordination), and dysarthria (slurred speech and articulation problems), which can occur together or separately and are evidence of a cerebellar syndrome (set of signs and symptoms characteristic of fairly severe damage to the cerebellum, a part of the brain used to maintain balance).
• neurological problems, sometimes severe, which can indicate encephalopathy (brain disease) and include confusion, agitation, tremors, myoclonus (involuntary muscle contractions), seizures, hallucinations, psychosis (personality problems), somnolence, and coma. These neurological signs usually occur in patients with kidney problems who have received higher-than-recommended doses or in elderly patients (see "Warnings and precautions"). These effects usually disappear when treatment is discontinued. The presence of these symptoms may be due to an overdose; talk to your doctor as soon as possible.

• Liver problems:acute liver injury.
• Respiratory problems:dyspnea (difficulty breathing).
• Immune system problems:anaphylactic reactions (generalized allergic reaction).
• Skin reactions:angioedema (sudden swelling of the face and neck).
• Kidney problems:acute kidney failure, especially in elderly people or those with kidney problems if the dose is exceeded, back pain around the kidney area, which may be associated with kidney problems (see also "Warnings and precautions").

The risk of acute kidney failure is caused by an overdose and/or dehydration, or by combination with medicines that are toxic to the kidneys.

These risk factors should be controlled, regardless of the patient's age. The risk of kidney problems can be avoided by following the posology, precautions for use (especially maintaining adequate hydration), and a slow administration rate.

Other side effects

Frequency not known:(frequency cannot be estimated from the available data)

• fatigue,
• fever.

Date of last revision of this leaflet: November 2022

---------------------------------------------------------------------------------------------------------------------------

The following information is intended for healthcare professionals only:

Preparation and Handling

It should be prepared immediately before use. Unused solution should be discarded.

Reconstitution:

Aciclovir Noridem should be reconstituted using the following volumes of water for injectable preparations or 9 mg/ml (0.9%) sodium chloride solution for injection to obtain a solution containing 25 mg of aciclovir per ml:

Volume of liquid for reconstitution formulation

500 mg vial 20 ml

Based on the calculated dose, the appropriate number and concentration of vials to be used should be determined.

To reconstitute each vial, the recommended volume of infusion liquid should be added and shaken gently until the vial contents are completely dissolved.

Administration

The required dose of Aciclovir Noridem should be administered by slow intravenous infusion over a period of one hour.

After reconstitution, Aciclovir Noridem can be administered using a controlled-rate infusion pump. Alternatively, the reconstituted solution can be further diluted to give an aciclovir concentration of no more than 5 mg/ml (0.5% w/v) for infusion.

The required volume of reconstituted solution should be added to the chosen infusion solution, as recommended below, and shaken well to ensure adequate mixing.

For children and neonates, in whom the volume of infusion liquid should be kept to a minimum, it is recommended that the dilution be based on 4 ml of reconstituted solution (100 mg of aciclovir) added to 20 ml of infusion liquid.

For adults, it is recommended to use infusion bags containing 100 ml of infusion liquid, even if this provides a substantially lower aciclovir concentration than 0.5% w/v. Therefore, a 100 ml infusion bag can be used for any dose between 250 mg and 500 mg of aciclovir (10 and 20 ml of reconstituted solution), but a second bag should be used for doses between 500 mg and 1000 mg.

When diluted according to the recommended schemes, Aciclovir Noridem is known to be compatible with the following infusion liquids:

• 9 mg/ml (0.9%) sodium chloride solution for injection
• Intravenous infusion of sodium chloride (0.45% w/v)
• Intravenous infusion of sodium chloride (0.18% w/v) and glucose (4% w/v).
• Intravenous infusion of sodium chloride (0.45% w/v) and glucose (2.5% w/v).
• Intravenous infusion of compound sodium lactate (Hartmann's solution).

Aciclovir Noridem, when diluted according to the above scheme, provides an aciclovir concentration not exceeding 0.5% w/v

Since no antimicrobial preservative is included, reconstitution and dilution must be carried out under completely aseptic conditions, immediately before use, and any unused solution should be discarded.

Reconstituted or diluted solutions should not be refrigerated.

If visible turbidity or crystallization appears in the solution before or during infusion, the preparation should be discarded.

Disposal of unused medicinal products and all materials that have come into contact with them should be carried out in accordance with local regulations.

Incompatibilities

This medicinal product should not be mixed with other medicinal products except those mentioned in the Administration section.

Posology and Method of Administration

Posology

The dose for patients with normal renal function is indicated below. In patients with abnormal renal function, the posology should be adapted according to the level of renal insufficiency (see section Patients with renal insufficiency).

Regarding recommendations on the duration of treatment, see the section Duration of treatment.

Posology in patients with normal renal function

Adults and adolescents (>12 years)

• Varicella-zoster virus (VZV) infections: 10 mg/kg every 8 hours; 10-15 mg/kg every 8 hours in pregnant women;
• Herpes simplex virus (HSV) infections (except meningoencephalitis): 5 mg/kg every 8 hours.
• Herpetic meningoencephalitis: 10 mg/kg every 8 hours

Patients with obesity should be given the recommended dose for adults based on ideal body weight rather than actual body weight.

Pediatric population

Children over 3 months of age

In children between 3 months and 12 years of age, the dose should be calculated according to body weight.

• HSV infection (except meningoencephalitis) or VZV infections: 10 mg/kg every 8 hours, with a maximum dose of 400 mg every 8 hours.
• HSV meningoencephalitis or VZV infection in immunocompromised children: 20 mg/kg every 8 hours, with a maximum dose of 800 mg every 8 hours.

Neonates

In neonates and infants up to 3 months of age, the dose is calculated based on body weight.

• Known or suspected neonatal herpes, the recommended regimen is 20 mg/kg of body weight intravenously every 8 hours for 21 days for disseminated or CNS disease, or for 14 days for disease confined to the skin and mucous membranes.

Posology in patients with renal insufficiency

The interval between doses and posology should be adjusted according to creatinine clearance in ml/min for adults and adolescents and in ml/min/1.73 m2 for infants and children under 13 years. Caution is recommended when administering aciclovir by infusion to patients with renal insufficiency. In such patients, care should be taken to ensure adequate fluid intake.

The following dose adjustments are proposed.

Recommended dose adjustment in adults and adolescents > 12 years with renal insufficiency:

Dose adjustment in children ≤ 12 years, infants and neonates with renal insufficiency:

Older adults

The possibility of renal insufficiency should be considered in older adults and the posology adjusted according to creatinine clearance (see section "Posology in patients with renal insufficiency").

Adequate fluid intake should be ensured.

Duration of Treatment

The duration of treatment is generally 5 days, but may be adjusted according to the patient's condition and response to treatment. The duration is:

• 8-10 days for varicella-zoster virus infections
• 10 days for the treatment of herpetic meningoencephalitis; may be adjusted according to the patient's condition and response to treatment
• 5-10 days for other herpes simplex virus infections
• 14 days for the treatment of neonatal herpes for mucocutaneous (skin/eye/mouth) infections
• 21 days for the treatment of neonatal herpes for disseminated or CNS disease.

The duration of prophylactic treatment with Aciclovir Noridem is determined by the duration of the risk period.

Method of Administration

Strictly intravenous route:

Each dose should be injected slowly intravenously (by pump or infusion) for at least one hour.

To consult the instructions for reconstitution of the medicinal product before administration, see the section Preparation and Handling.

Overdose

Symptoms and signs

Overdose of intravenous aciclovir has caused increased serum creatinine, blood urea, and consequent renal insufficiency. Neurological effects such as confusion, hallucinations, agitation, seizures, and coma have been described in association with overdose.

Treatment

Patients should be closely monitored for any signs of toxicity.

Hemodialysis significantly increases the elimination of aciclovir from the bloodstream and may be considered as a treatment option in cases of symptomatic overdose.
