Aciclovir 200mg

Buy Aciclovir for Genital Herpes

Aciclovir is an antiviral drug used to stop the herpes simplex virus (HSV) from multiplying. It won't completely clear the virus from your body and only suppresses HSV whilst you take it. Aciclovir is usually taken five times per day for a minimum of five days for acute outbreaks. A longer course is required if new blisters or open sores are still forming when you start your treatment course. For the suppression of chronic genital herpes, a lower dose is taken each day, usually for six to 12 months. You will be prescribed the appropriate dose and duration based on your medical history.

All our products are genuine UK medicines and are dispensed by our partner pharmacy based in the UK.
