What SHILOVA tablets are used for
How SHILOVA tablets work
SHILOVA tablets belong to a group of medicines called antivirals. SHILOVA tablets are used for the treatment of genital herpes infection, shingles (infection zoster), ophthalmic zosters (shingles affecting the eye region), cold sores (herpes labialis) and for the prevention of Cytomegalovirus (CMV) infection in people following an organ transplant.
SHILOVA tablets work by stopping the multiplication of the virus which causes herpes, shingles and cold sores. They can reduce the length and severity of an outbreak of herpes, shingles and cold sores and the duration of pain and shorten the time to healing of crusts associated with herpes.
SHILOVA tablets do not eliminate the herpes virus from the body. The herpes virus is also known as the Herpes Simplex Virus, or HSV.
SHILOVA tablets help the blisters to heal more quickly. If you start taking them as soon as you feel an outbreak starting, you may actually prevent the blisters from developing.
SHILOVA tablets can also be taken long term to help prevent the HSV infection coming back.
SHILOVA tablets can also reduce the risk of transmitting the virus that causes genital herpes in patients who are taking it continuously to prevent or reduce recurrent outbreaks. It does not cure genital herpes or completely eliminate the risk of transmission. Therefore, in addition to therapy with SHILOVA, it is recommended that patients avoid contact when symptoms are present and always use condoms.
SHILOVA (or any other antiviral) is not a cure for genital herpes. Because genital herpes is a sexually transmitted disease, you should minimise having intercourse when you have an outbreak of herpes or show any symptoms. This will avoid the risk of spreading herpes to your partner.
It is important the treatment for shingles is started within the first three days of the shingles attack.
For the treatment of cold sores the tablets should be taken at the earliest symptom of a cold sore (e.g. tingling, itching, or burning).
SHILOVA is used to prevent the cytomegalovirus (CMV) infection in people following an organ transplant.
CMV is a common viral infection caused by human herpes virus. It can be spread by contact with infectious blood or body secretions (e.g. saliva, urine, cervical mucous, or semen). CMV may cause symptoms similar to glandular fever (fatigue, fever, sore throat and swollen glands).
SHILOVA tablets are more effective inpatients 50 years of age and older.
Ask your doctor if you have any questions about why SHILOVA tablets have been prescribed for you.
SHILOVA tablets are not addictive.
