Consumer Information
Information about the product including what the product is used for, dosage, warnings, proper use and side effects. This summary will not tell you everything about the product. Contact your healthcare professional if you have any questions about the product.
What the medication is used for
ACT FAMCICLOVIR is an antiviral medicine that is used to treat a number of viral infections described below. It stops the infecting virus from reproducing. Since the virus reproduces very early in the infection, the best results in the treatment are obtained if ACT FAMCICLOVIR is started as soon as possible after the first symptoms appear.
Herpes zoster:
ACT FAMCICLOVIR is used to treat herpes zoster (Shingles). Herpes zoster is an infection caused by a virus called varicella zoster (the same virus that causes chickenpox). ACT FAMCICLOVIR stops the virus from spreading in the body so that healing can occur faster if taken within 72 hours of the first lesion, and reduces the blistering, pain, and rash.
Genital herpes:
ACT FAMCICLOVIR is used to treat or prevent recurrence of the viral infections which cause genital herpes. Genital herpes is a viral infection caused by herpes simplex virus type 1 or 2, and is normally spread by sexual contact. It causes blisters and burning or itching around the genitals, which may be painful.
ACT FAMCICLOVIR does not stop you from spreading herpes to another person. It is important to understand that the drug must be taken as early as possible as soon as you know that an attack is starting. Although ACT FAMCICLOVIR does not cure the viral infection, it helps to shorten the duration of symptoms and allows the infections to heal faster.
What it does
ACT FAMCICLOVIR helps stop the virus from multiplying and shortens the time the virus is released and spread, which helps healing.

How long do I use ACT FAMCICLOVIR?
The usual adult dose is one ACT FAMCICLOVIR tablet three times a day for shingles. Follow your doctor’s instructions about how and when to take your tablets. Start taking them as soon as you can for the best effect.
Most people take one tablet when they get up in the morning, one in the middle of the afternoon and one before going to bed at night.
Finish all the tablets you have been given even if you start to feel better. The treatment lasts for seven days.
Treating an outbreak of recurrent genital herpes:
If you have had herpes infections of the genitals before (called recurrent genital herpes), your doctor may decide to treat the outbreak. You will likely be told to take one 125 mg tablet twice a day for 5 days or if you are HIV-positive, one 500 mg tablet twice a day for 7 days. Most people with recurrent genital herpes take one tablet when waking, and one tablet just before going to bed. ACT FAMCICLOVIR should be taken as soon as possible after the early symptoms (pain, burning, blisters, itching, tingling) begin to appear.
Preventing outbreaks of recurrent genital herpes:
If you have had herpes infections of the genitals before (called recurrent genital herpes), then your doctor may decide to prevent future outbreaks. Your doctor will likely tell you that you should continually take one 250 mg tablet twice a day. Most people with recurrent genital herpes take one tablet when waking, and one tablet just before going to bed.
Overdose
In case of drug overdose, contact a healthcare practitioner (doctor), hospital emergency department or regional poison control center, even if there are no symptoms. Bring your pack of tablets with you.
Taking too much of any type of medicine is risky.
Taking too much ACT FAMCICLOVIR may affect the kidneys. In people who already have kidney problems it may, rarely lead to kidney failure if their dose is not correctly lowered.
Important: Your doctor may give you different instructions better suited to your specific needs. If you need more information on how to take ACT FAMCICLOVIR properly, double-check with your doctor or pharmacist.
Missed Dose
If you miss taking a ACT FAMCICLOVIR tablet, don’t worry. Take it as soon as you remember. Take your next tablet at the normal time. However, do not take two doses within a time interval of less than 1 hour, in that case you should skip the missed dose. Carry on as normal until you have finished all the tablets. It is important that you finish all the tablets you have been given, unless your doctor tells you to stop taking them. Do not double-dose.

More information about shingles.
What is shingles like?
- At first you might feel burning and tingly where the rash is coming. You may get pain for a few days before you see the rash.
- Most people with shingles get a blistery rash down one side of their body or face. This can be painful.
- New blisters will keep coming for about five days. After this, the blisters will dry to form scabs.
- You may feel weak and tired.
- The rash usually lasts for two to three weeks. Afterwards, people can have pain where the rash was, sometimes for several months.
Who gets shingles?
People of any age can get shingles. Most people who get it are middle-aged or older.
You can only get shingles if you have had chickenpox. 50% of people have had shingles by the age of 85.
What causes shingles?
- Shingles is caused by the same virus that causes chickenpox.
- After you have had chickenpox, the inactive virus stays in your body.
- Many years later the virus can start to work again. This may happen when you are run down or tired.
How is shingles treated?
Tablets for shingles, such as ACT FAMCICLOVIR, stop the virus spreading. They cut down blistering and pain of the rash. They help you get better quicker if you take them early in your illness.
What else can you do?
- To stop the rash itching, have cool baths - do not use perfumed soap or bath oils. You can also put ice cubes wrapped in a washcloth on the rash, or cover it with a soothing lotion like calamine for the first three days.
- Keep the rash clean and dry.
- Wear loose clothes.
- Do not scratch the rash. It could get infected and take longer to get better.
- Rest when you feel tired.
- Try to eat well and drink plenty of fluids.
- Tell your doctor right away if you start to have trouble with your eyes. Shingles can sometimes cause eye problems which can be treated.
Can other people catch your shingles?
Shingles is caused by the same virus that causes chickenpox. Most doctors agree that people do not catch shingles from each other. When you have shingles, you can give chickenpox to someone who has never had chickenpox before - but this is unlikely.
What is Genital Herpes?
Genital Herpes is a viral infection of the genital (sex organ) area which is caused by the Herpes Simplex Virus. You might suspect the onset of this infection if you see the appearance of sores or blisters or feel a burning sensation in your genital region.
Type II herpes simplex virus is the main cause of the sores and blisters that develop in your genital area, but you can also catch genital herpes from herpes simplex Type I which can be the cause of cold sores which occur around your mouth.
Genital Herpes can occur as a first-episode attack or recurrent infection. Unlike many other viruses, recovery from the first attack does not leave you with lifelong protection from re- infection. The virus is able to remain hidden in the nerves after the initial infection and stays there until reactivated.
Since your body still carries the highly infectious virus, you can easily infect someone else, even if you feel fine and you have no symptoms of genital herpes. This explains why genital herpes is one of the most common sexually transmitted diseases (STD).
The risk is higher for people who are more sexually active and have more sexual partners. It is therefore recommended that you avoid sexual activity if you or your partner have any symptoms of herpes, even if you have started your treatment.
"If you are taking ACT FAMCICLOVIR to treat or to suppress genital herpes, or you have had genital herpes in the past, you should still practice “safer sex”, including the use of condoms. This is important to prevent you passing the infection on to others.
While taking this medication:
- remember that your infection is contagious.
- tell any other doctor, pharmacist or dentist you see, that you are taking ACT FAMCICLOVIR.
- contact your doctor if you develop any unusual discomfort.
- you should not take ACT FAMCICLOVIR when pregnant or breast-feeding unless your doctor tells you to.
- do not give ACT FAMCICLOVIR to others because it may not be suitable for them.
- store your tablets in a dry place at room temperature in the original container provided by the pharmacy.
- keep this medication out of reach of children.
- read your prescription label carefully; consult your doctor or pharmacist if you have any questions or require further information.
