LoginAgrylin
Generic Name: anagrelide hydrochloride
Product Name: Agrylin
Indication: What Agrylin is used for
Agrylin Capsules contain a medicine called anagrelide hydrochloride which acts upon the bone marrow and prevents it from producing too many of the blood cells known as “platelets“.
In a disease such as thrombocythaemia, the bone marrow produces too many of these cells, and the very large numbers of platelets in the blood can cause serious problems with blood circulation. By preventing too many platelets from being made, Agrylin Capsules can help prevent serious problems with blood circulation due to overproduction of platelets by the bone marrow, helping manage thrombocythaemia.
Your doctor may have prescribed Agrylin Capsules for another reason. Ask your doctor if you have any questions about why Agrylin Capsules have been prescribed for you.
Agrylin Capsules are not addictive.
Agrylin Capsules are only available on a doctor’s prescription.
Action: How Agrylin works
The precise mechanism by which anagrelide reduces blood platelet count is unknown. In cell culture studies, anagrelide suppressed expression of transcription factors including GATA-1
and FOG-1 required for megakaryocytopoiesis, ultimately leading to reduced platelet production. In vitro studies of the growth of human megakaryocyte colonies in tissue culture showed that anagrelide disrupted the postmitotic phase of megakaryocyte development reducing megakaryocyte size and ploidy.
Each Agrylin Capsule contains 0.5 mg of the active ingredient anagrelide hydrochloride.
Agrylin Capsules also contain the inactive ingredients crospovidone, lactose anhydrous, lactose monohydrate, magnesium stearate, microcrystalline cellulose, and povidone.
Agrylin Capsules are available in plastic bottles containing 100 capsules.

Before you start to take it
Tell your doctor if:
- You have any allergies;
- You have had or now have any liver or kidney disease;
- You have heart disease, heart failure or are at high risk of vascular events (thrombosis or bleeding).
If you become pregnant whilst taking Agrylin Capsules, you should stop taking the capsules and see your doctor immediately. Women taking Agrylin Capsules and who are at risk of becoming pregnant should make sure that they are using adequate contraception.
Agrylin Capsules should not be taken by anyone under 16 years of age.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop. Some medicines and Agrylin Capsules may interfere with each other. These include:
- Aspirin or a medicine containing aspirin;
- Medicines used to treat depression such as fluvoxamine;
- Medicines used to treat gastrointestinal problems such as omeprazole;

How to take Agrylin Capsules
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained here.
How much to take
The recommended adult starting dose of anagrelide is 1 mg/day, which can be taken orally in two divided doses. This dosage will then be adjusted until your doctor has decided which dosage is best for you. Any single dose taken during the day should not exceed 2.5 mg. Your total daily dose should not exceed four times this, i.e. 10 mg (20 of the 0.5 mg capsules).
If you are elderly, you should take the normal adult dose.
When to take it
Take your capsules the same time each day. This will help you remember when to take the capsules.
Food reduces the absorption of Agrylin slightly, but this does not have any effect on the ability of Agrylin to reduce your platelet count.
How long to take it
You should not normally stop taking Agrylin Capsules unless your doctor tells you to. If Agrylin Capsules have been successfully reducing the excess of platelets in your blood, stopping Agrylin Capsules will cause the number of platelets in your blood to rise again within three or four days, so that the risk of problems with blood circulation may return.
If you feel unwell during your course of treatment, tell your doctor.
If you forget to take Agrylin Capsules
If you forget to take a dose of Agrylin Capsules, leave out that dose completely. Take your next dose at the normal time it is due.
Do not take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering to take Agrylin Capsules, ask your pharmacist for some hints.
If you take too many Agrylin Capsules
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Agrylin Capsules. Do this even if there are no signs of discomfort or poisoning.
Symptoms of an overdose may include fast heartbeat, vomiting, and bleeding.
