Always consult your doctor or pharmacist before taking aciclovir tablets.
If your condition does not improve or becomes worse, then call your doctor.
Driving or operating machinery is okay, as there have been no studies to investigate the effect of acyclovir on driving performance or the ability to operate machinery. As aciclovir administration is occasionally associated with drowsiness and somnolence (usually in patients receiving high doses or with impaired renal function), patients should make sure that they are not affected before driving or using machinery.
Do NOT use aciclovir tablets if:
- You are allergic to any of the ingredients in the tablet.
Use of aciclovir tablets during pregnancy or breast feeding is fine after consulting with your doctor. It is not known if this medicine is found in breast milk. If you are or will be breast-feeding while you use acyclovir tablets, check with your doctor. Consult your doctor or health care professional before taking aciclovir tablets.
Refer to your doctor or pharmacist for guidelines on dosage. Do not exceed what they advise.
The usual dose for adults is: 200mg aciclovir should be taken five times daily at approximately four-hourly intervals omitting the night time dose. Treatment should continue for five days, but in severe initial infections, this may have to be extended.
The usual dose for children. Treatment of herpes simplex infections, and prophylaxis of herpes simplex infections in the immunocompromised: children aged two years and over should be given the adult doses and children below the age of two years should be given half the adult dose.
Treatment of varicella infection: children under 2 years should be given 200mg four times daily. Children aged 2-5 years should be given 400mg four times daily. Children aged 6 years and over should be given 800mg four times daily. Treatment should continue for 5 days. Dosing may be more accurately calculated as 20mg/kg body weight (not to exceed 800mg four times daily).
Interaction with other medical products: aciclovir is eliminated primarily unchanged in the urine via active renal tubular secretion. Any drugs administered concurrently that compete with this mechanism may increase aciclovir plasma concentrations.
Consult with your doctor about any medications you are taking, before your treatment with aciclovir tablets.
