What FAVIC FOR COLD SORES is used for
FAVIC FOR COLD SORES is an antiviral medicine that is used to treat recurrent outbreaks of cold sores in adults who have a normal immune system (the body system which fights against harmful bacteria, viruses and fungi).
Cold sores are an infection caused by a virus called herpes simplex type 1 (HSV-1). The infection is most commonly acquired as a baby or child from contact with parents or relatives, often from kissing.
Cold sores usually begin on or around the lips, mouth, and nose as small red bumps that turn into fluid-filled blisters. Cold sores can be tender and painful. Many people who get cold sores know when one is coming by a tingling, burning, itchy or painful sensation or redness in the area. This can happen very rapidly.
After redness and swelling develop, blisters form. The blisters may weep or burst and this can be painful. Then a shallow ulcer and yellow crust form as the cold sore dries. The crust eventually falls off, exposing new pink-coloured skin. Generally, the sores heal without scarring. After the initial infection has healed, the virus becomes dormant in nerve cells.
Cold sores can be unpredictable. The virus can become active again in the body, even after many years, resulting in recurrent outbreaks.
Even after many years, some people may experience recurring cold sores due to viral reactivation.
Some common triggers to a cold sore may include:
- sun exposure
- menstrual periods
- dry chapped lips
- skin trauma
- a cold.
FAVIC FOR COLD SORES does not cure the viral infection, however it helps to relieve the symptoms and shorten the duration of an outbreak.
The best results are obtained if the medicine is started as soon as possible after the first symptoms or signs of a cold sore are noticed. These include tingling, itching or burning, or the appearance of redness or swelling. This is when the virus is reproducing rapidly.
There is no evidence that FAVIC FOR COLD SORES is addictive.
FAVIC FOR COLD SORES is not recommended for use in children or adolescents under 18 years of age.

A single dose of FAVIC FOR COLD SORES is all that is necessary for treating each episode of cold sores. Each pack of FAVIC FOR COLD SORES contains enough medicine for one dose.

Things that may help your condition
Cold sores are contagious and the virus can be passed on from person to person through close physical contact or saliva, even when blisters are not present. The risk is much higher when the cold sore is visible, as the virus can be shed, making it easy to infect other people.
Take the following precautions to avoid spreading the virus:
- keep the areas affected by the virus as clean and dry as possible
- avoid touching or scratching the sore area as you may spread the virus on your fingers
- do not share any objects that have been in contact with a cold sore (e.g. drinking glasses, eating utensils, or towels)
- avoid direct skin-to-skin contact of the area with other people (e.g. kissing) until the cold sore has healed.
Tell your pharmacist or doctor as soon as possible if you do not feel well while you are taking FAVIC FOR COLD SORES. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask your pharmacist or doctor to answer any questions you may have.
Tell your pharmacist or doctor if you notice any of the following and they worry you:
- nausea (feeling sick) or vomiting
- stomach pain
- itching or an itchy rash (urticarial).
These side effects are usually mild.
Tell your pharmacist or doctor as soon as possible if you notice any of the following:
- a rash that is separate from the shingles rash
- extreme sleepiness or confusion, usually in older people
- hallucinations (seeing or hearing things that are not really there)
- painful or swollen joints
- aching muscles or muscle tenderness or weakness that is not caused by exercise.
You may need medical attention if you have the above side effects.
Tell your pharmacist or doctor immediately, or go to Accident and Emergency at the nearest hospital if you notice any of the following:
- bruising or bleeding more easily than usual as it may indicate that the number of platelets (a type of blood cell responsible for blood clotting) in your blood are reduced
- signs of a serious skin or mouth reaction, which may include widespread red, raised areas, blisters or sores
- signs of a possible liver problem such as persistent pain in the upper right abdomen, yellowing of the skin and/or eyes, dark urine or pale bowel motions.
