Aciclovir Tablets BP 200 mg

What is Aciclovir Tablets BP 200 mg?

Aciclovir Tablets BP 200 mg contain aciclovir, an antiviral medicine used in the management of certain herpesvirus infections. The tablet formulation provides 200 mg of aciclovir per tablet and is generally used for infections caused by herpes simplex virus, with treatment depending on the specific indication and healthcare professional assessment.

Uses / Indications

Aciclovir Tablets BP 200 mg may be indicated for the management of certain herpesvirus infections, including:

• Herpes simplex virus (HSV) infections
• Genital herpes caused by HSV
• Recurrent herpes simplex infections
• Certain mucocutaneous herpes simplex infections
• Other susceptible herpesvirus infections where oral aciclovir therapy is considered appropriate

The exact indication and treatment duration should be determined according to the approved product information and healthcare professional assessment.

Benefits

• Provides antiviral activity against susceptible herpes simplex viruses.
• Helps inhibit viral replication, supporting management of active herpesvirus infections.
• May be used in selected cases for treatment or suppression of recurrent herpes simplex infections.
• Oral tablet formulation provides a convenient dosage form for systemic antiviral therapy.
• Aciclovir is an established antiviral agent used in the management of susceptible herpesvirus infections.

Side Effects

Common Side Effects

Possible adverse effects may include:

• Headache
• Nausea
• Vomiting
• Diarrhoea
• Abdominal discomfort
• Skin rash or itching

Less Common or Serious Side Effects

Less common but clinically important reactions may include:

• Dizziness or confusion
• Tremor or other neurological symptoms, particularly in patients with renal impairment or excessive exposure
• Severe skin or allergic reactions
• Kidney-related adverse effects, including changes in renal function

Severe or unusual symptoms should receive prompt medical attention.

How Does It Work?

Aciclovir is a synthetic nucleoside analogue antiviral agent.

Aciclovir

Aciclovir is converted preferentially within herpesvirus-infected cells into its active triphosphate form. The active metabolite inhibits viral DNA polymerase and can become incorporated into viral DNA, interfering with further viral DNA synthesis. This limits replication of susceptible herpesviruses.

The antiviral effect is selective because activation of aciclovir is favoured in virus-infected cells.

Dosage Guidelines

The appropriate dose and treatment duration depend on factors such as:

• Age
• Body weight where relevant
• Type and severity of infection
• Frequency or recurrence of infection
• Renal function
• Other medicines being taken
• Treatment response
• Healthcare professional assessment

The exact dose and treatment duration should follow the approved product information and the recommendation of a qualified healthcare professional.

For tablets:

• Take exactly as prescribed.
• Swallow with sufficient water unless otherwise directed.
• Maintain the prescribed dosing schedule.
• Do not alter, crush or split the tablet unless permitted by the approved product information.
• Adequate fluid intake may be important during treatment, particularly in patients at risk of renal problems.

When Not to Use

Aciclovir Tablets BP 200 mg should not be used in patients with a known hypersensitivity to aciclovir, valaciclovir or any relevant component of the formulation.

Particular caution and professional assessment may be required in patients with:

• Renal impairment
• Significant dehydration
• A history of neurological adverse reactions associated with antiviral treatment
• Conditions requiring medicines that may affect kidney function

Drug / Product Interactions

Clinically relevant interactions may occur with medicines that influence aciclovir exposure or renal elimination.

Particular attention may be required with:

• Probenecid
• Cimetidine
• Mycophenolate mofetil
• Medicines that may affect renal function
• Other medicines requiring renal-dose considerations

Healthcare professionals should review concomitant medicines, particularly in patients with impaired renal function.

Safety Advice

Overdose

If an overdose is suspected, seek immediate medical attention or contact an appropriate poison-control or emergency medical service.

Missed Dose

Take the missed dose when remembered unless it is nearly time for the next scheduled dose. If the next dose is due soon, skip the missed dose and continue with the regular schedule. Do not double the next dose unless specifically directed by a healthcare professional.

Pregnancy

Aciclovir should be used during pregnancy only after appropriate healthcare professional assessment of the potential benefits and risks.

Breastfeeding

Aciclovir passes into breast milk. Appropriate professional advice should be obtained before use during breastfeeding.

Children

Use in children should follow the approved product information and an appropriate healthcare professional’s recommendation.

Elderly Patients

Older patients may require particular attention to renal function because aciclovir is primarily eliminated through the kidneys.

Renal Impairment

Dose adjustment may be necessary in patients with impaired renal function. Adequate hydration and appropriate clinical monitoring may be important.

Driving

Dizziness, confusion or other neurological effects may occur in some patients. Patients experiencing such effects should exercise caution with driving or operating machinery.

General Instructions

• Take according to the prescribed schedule.
• Swallow with sufficient water unless otherwise directed.
• Do not alter the dosage form unless permitted.
• Follow the approved product information.
• Keep the tablets in their original packaging where appropriate.
• Do not share prescription medicines with other people.
• Complete the prescribed course unless a healthcare professional advises otherwise.

Special Dietary / Lifestyle Tips

No specific dietary restriction is generally required unless advised by a healthcare professional.

Adequate fluid intake may be particularly relevant for patients receiving aciclovir who have an increased risk of renal impairment.

Comparison with Other Treatments

Aciclovir belongs to the antiviral class of medicines and is used specifically against susceptible herpesviruses. Other antiviral medicines may have different antiviral spectra, pharmacokinetic characteristics, dosing schedules and approved indications.

Compared with topical antiviral formulations, oral aciclovir provides systemic exposure and may be selected when systemic antiviral treatment is appropriate. The choice between aciclovir and other antiviral therapies depends on the infection, patient-specific factors, renal function, treatment history and approved prescribing information.

Precautions & Warnings

• Confirm any history of hypersensitivity to aciclovir or valaciclovir before use.
• Use with appropriate caution in patients with renal impairment.
• Dose adjustment may be required according to renal function.
• Maintain adequate hydration where clinically appropriate.
• Use during pregnancy or breastfeeding only following appropriate professional assessment.
• Elderly patients may require closer attention to renal function.
• Review concomitant medicines for clinically relevant interactions.
• Neurological adverse effects are more likely to require attention in patients with significant renal impairment or excessive drug exposure.
• Seek medical attention for severe allergic reactions, significant neurological symptoms or symptoms suggestive of kidney problems.

Can I Use It With Other Medicines?

Generally Compatible With

Professional advice is particularly important when aciclovir is used with:

• Probenecid
• Cimetidine
• Mycophenolate mofetil
• Potentially nephrotoxic medicines
• Other medicines that may require renal-dose adjustment

Do not start, stop or change concomitant medicines without appropriate healthcare professional advice.
