Zovirax Duo contains two active substances: acyclovir and hydrocortisone, which help combat the Herpes simplex virus.
- Aciclovir is antiviral and helps fight the virus that causes herpes.
- Hydrocortisone is a mild steroid to reduce the inflammation associated with cold sores.
Herpes simplex is caused by the herpes simplex virus. This virus causes blisters and sores, mostly on the lips but also on other parts of the face. Cold sores can develop when the body’s immune system is weakened, for example during a cold or other infection. Stress, strong sunlight, cold temperatures, or your period can also trigger cold sores.
Zovirax Duo cream is used:
- to treat early signs and symptoms of cold sores on the lips and skin around the mouth (such as tingling, itching or redness) to reduce the risk of developing cold sores in adults and adolescents 12 years and older.
Even if the cold sores have blistered, treatment with Zovirax Duo reduces the healing time of lesions by about half to a day compared to a cream that does not contain active substances.
If symptoms persist 5 days after stopping treatment, you should see your doctor.
