View Patient InformationAciclovir is an antiviral medication available in both tablet and cream forms. The tablets are commonly used to treat genital herpes, shingles, or severe cases of chickenpox, while the cream is applied directly to cold sores. In some cases, people with weakened immune systems may take aciclovir daily to help prevent herpes-related infections. It is important to read the patient information leaflet carefully for a complete list of possible side effects and precautions.
The herpes virus can cause painful blisters on the skin, lips, or genital area. Aciclovir works by preventing the herpes virus from multiplying within the body, helping to stop the infection from worsening, relieve pain, and promote healing of the blisters. However, even after symptoms have cleared, the virus can remain dormant in the body, meaning that flare-ups can occur in the future. This explains why some people experience recurring cold sores, despite treating them each time. It also highlights the importance of avoiding direct contact with someone who has an active cold sore or genital herpes, as the virus can still be transmitted.
Aciclovir is an antiviral medication used to relieve pain and accelerate the healing of blisters or sores caused by conditions such as:
Chickenpox (varicella)
Shingles (herpes zoster)
Initial or recurrent episodes of genital herpes
It may also be prescribed to help prevent future outbreaks of genital herpes in individuals who are already infected with the virus.
Aciclovir belongs to a group of antiviral drugs known as synthetic nucleoside analogues. These medications work by slowing the growth and spread of the virus, allowing the body to better control the infection.
Aciclovir is an antiviral drug used to control infections caused by the herpes virus. It works by inhibiting the virus’s ability to replicate within the body, which helps lessen symptoms and promotes faster healing.
It’s important to note that Aciclovir does not:
Cure herpes infections
Prevent the transmission of the virus to others
Aciclovir typically begins to take effect within a few days. Many people notice a reduction in symptoms within 24 to 48 hours.
If you’re using Aciclovir to prevent recurrent outbreaks of genital herpes, it remains effective as long as you continue taking it consistently as prescribed.
Although Aciclovir doesn’t cure herpes infections, it provides several key benefits:
Eases pain associated with chickenpox, shingles, and genital herpes
Accelerates the healing process of blisters and sores during outbreaks
Helps control symptoms, making recovery quicker and more comfortable
