Warnings and precautions
Consult your doctor or pharmacist before starting to take Aciclovir Stada.
Taking Aciclovir Stada with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
In particular, tell your doctor if you are taking any of the following medicines:
- interferon(a medicine used to treat multiple sclerosis), may increase the effects of both medicines.
- zidovudine(a medicine used to treat AIDS), may cause disorders in the nervous system (neuropathies), seizures, and lethargy.
- theophylline(used in asthma and other respiratory problems).
- cimetidine(used to treat peptic ulcers) and probenecid (used to treat gout), as they increase the concentration of aciclovir.
- mycophenolate mofetil(a medicine used in transplant patients). You should be careful if you are taking high doses of aciclovir, as the blood levels of both medicines may be increased.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
There is not enough information available on the consequences of using aciclovir during pregnancy. You should consult your doctor or pharmacist if you are pregnant.
Breastfeeding
Aciclovir is excreted in breast milk. Similarly, not enough is known about its consequences. Therefore, consult your doctor or pharmacist if you are breastfeeding.
Driving and using machines
It is not known whether aciclovir affects the ability to drive or use machines. Although the properties of aciclovir make such an effect unlikely, fatigue, headache, and effects on the nervous system have been reported. You should take this into account if you plan to drive or use machines during treatment with aciclovir.
Aciclovir Stada contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet, which is essentially "sodium-free".
3. How to take Aciclovir Stada

Always take this medicine exactly as your doctor has told you. In some cases, the dose may be different from the recommended dose. Consult your doctor if you are not sure.
The recommended dose is:
One tablet of aciclovir 800 mg, 5 times a day, every 4 hours. The dose is omitted during the night. Treatment should be started 48 hours after the infection appears. The duration of treatment should be 7 days.
Use in children

In principle, no dose adjustment is required in elderly patients. Only in cases of renal impairment may the doctor decide to adjust the dose.
Method of administration
Take the tablets with half a glass of water or other liquid.
In patients with kidney problems or elderly patients, make sure to drink plenty of liquid during treatment with aciclovir. It is also important that patients treated with high doses of aciclovir drink enough liquid.
