WHAT ZENTEL IS USED FOR
ZENTEL contains albendazole as the active ingredient.
ZENTEL is used to clear worms or parasites from the gut and other tissues. ZENTEL is effective against threadworm or pinworm, roundworm, whipworm, tapeworm and hookworm among others.
ZENTEL is thought to kill these worms by causing them to starve. The eggs, larvae and adult worms are affected.
Your doctor may have prescribed ZENTEL for another reason. Ask your doctor if you have any questions about why ZENTEL has been prescribed for you.
There is no evidence that ZENTEL is addictive.

HOW TO TAKE IT
Follow your doctors' instructions about how and when to use ZENTEL. Read the direction label carefully. If you have any concerns about how to take this medicine talk to your doctor or pharmacist.
How much to take
Your doctor will advise how many doses are needed each day, and for how long you will need to take ZENTEL. The usual dose for adults and children older than 2 years of age, is two ZENTEL tablets as a single dose.
For other conditions the dose prescribed by your doctor may be different. You should take the full course of tablets, and not just stop when you feel better.
Your doctor may need to see you two to four weeks after taking the dose or course. This is to make sure that ZENTEL has worked. A second dose or course of ZENTEL is sometimes needed.
How to take
You will be told whether to take the tablets with food or on an empty stomach, and it is important you follow these instructions. ZENTEL tablets are usually taken on an empty stomach. In some conditions the tablets may need to be taken after food.
ZENTEL tablets may be taken crushed or chewed or swallowed whole. No special laxative or fasting is needed.
If you forget to take
Take the missed tablets as soon as you remember. If you have been prescribed more than a single dose, do not try to make up for missed doses by taking more than two tablets at a time.
Taking more than the prescribed dose can increase the chance of unwanted side effects.
Immediately telephone your doctor or Poisons Information Centre (In Australia telephone 131126. In New Zealand telephone 0800 POISON) or go to the emergency department at your nearest hospital if you or anyone else has taken a large amount of ZENTEL. Do this even if there are no signs of discomfort or poisoning. Be sure to show the doctor the ZENTEL packet. There are unlikely to be any serious problems following an overdose of ZENTEL.
