How it works
Acitretin, the active ingredient of ZETIN, belongs to a group of medicines called retinoids.
It is very similar to Vitamin A which is obtained from our diet and is vital for the normal growth and development of the body, especially the skin.
Psoriasis is a skin disease with thickened patches of red skin, often with silvery scales. ZETIN is used to treat severe psoriasis and other severe skin disorders.
ZETIN works to return skin to normal when problems with the normal development of the skin are present, as in the case of severe psoriasis and some other skin disorders.
There is no evidence that this medicine is addictive.
Use in children
ZETIN capsules should only be taken by children where alternative therapy cannot be used.

How to take this medicine
Carefully follow all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines. This may also consider your bodyweight and whether you develop any side effects.
The starting dose is usually either 25 mg (1 x 25 mg capsule) or 30 mg (3 x 10 mg capsules) per day for 2 to 4 weeks.
Your dose will probably then be adjusted by your doctor when it is known how you respond to ZETIN capsules.
The initial signs of improvement may be seen in the first week but, more often, after 2 or 3 weeks. It may take 2 to 3 months until the full effect is seen.
Do not change your dosage without first checking with your doctor.
Affected skin areas will either peel off or steadily clear. Sometimes more redness or itching may be present at first, but this will normally improve as treatment continues.
How to take it
ZETIN capsules should be swallowed whole with a glass of water or milk.
When to take it
Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.
Female patients should wait until the 2nd or 3rd day of their menstrual period before starting ZETIN capsules.
This helps to ensure that you are not pregnant before you start to take ZETIN therapy.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
A temporary increase in psoriasis is sometimes seen when first starting treatment.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
