What Domassel is
Domassel belongs to a group of medicines called antiplatelet medicines.
What Domassel is used for
Ticagrelor in combination with acetylsalicylic acid (another antiplatelet agent) is to be used in adults only. You have been given this medicine because you have had: 

•    a heart attack, or
•    unstable angina (angina or chest pain that is not well controlled).

It reduces the chances of you having another heart attack, stroke or dying from a disease related to your heart or blood vessels. 
How Domassel works 
Domassel affects cells called ‘platelets’ (also called thrombocytes). These very small blood cells help stop bleeding by clumping together to plug tiny holes in blood vessels that are cut or damaged. 
However, platelets can also form clots inside diseased blood vessels in the heart and brain. This can be very dangerous because: 

•    the clot can cut off the blood supply completely; this can cause a heart attack (myocardial
•    infarction) or stroke, or
•    the clot can partly block the blood vessels to the heart; this reduces the blood flow to the heart and can cause chest pain which comes and goes (called ‘unstable angina’).

Domassel helps stop the clumping of platelets. This reduces the chance of a blood clot forming that can reduce blood flow. 

Do not take Domassel if:
You are allergic to Domassel or any of the other ingredients of this medicine
•    You are bleeding now.
•    You have had a stroke caused by bleeding in the brain.
•    You have severe liver disease.
•    You are taking any of the following medicines:
→    ketoconazole (used to treat fungal infections)
→    clarithromycin (used to treat bacterial infections)
→    nefazodone (an antidepressant)
→    ritonavir and atazanavir (used to treat HIV infection and AIDS)

Do not take Domassel if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine. 
Warnings and precautions 
Talk to your doctor or pharmacist before taking Domassel if: 

•    You have an increased risk of bleeding because of:
-    a recent serious injury
-    recent surgery (including dental work, ask your dentist about this)
-    you have a condition that affects blood clotting
-    recent bleeding from your stomach or gut (such as a stomach ulcer or colon ‘polyps’)
•    You are due to have surgery (including dental work) at any time while taking Domassel. This is because of the increased risk of bleeding. Your doctor may want you to stop taking this medicine 5 days prior to surgery.
•    Your heart rate is abnormally low (usually lower than 60 beats per minute) and you do not already have in place a device that paces your heart (pacemaker).
•    You have asthma or other lung problems or breathing difficulties.
•    You have had any problems with your liver or have previously had any disease which may have affected your liver.
•    You have had a blood test that showed more than the usual amount of uric acid

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking this medicine. 
If you are taking both Domassel and heparin: 

•    Your doctor may require a sample of your blood for diagnostic tests if they suspect a rare platelet disorder caused by heparin. It is important that you inform your doctor that you are taking both Domassel and heparin, as Domassel may affect the diagnostic test.

Children and adolescents 
Domassel is not recommended for children and adolescents under 18 years. 
Other medicines and Domassel 
Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because Domassel can affect the way some medicines work and some medicines can have an effect on Domassel. 
Tell your doctor or pharmacist if you are taking any of the following medicines: 

•    more than 40 mg daily of either simvastatin or lovastatin (medicines used to treat high cholesterol)

•    rifampicin (an antibiotic)
•    phenytoin, carbamazepine and phenobarbital (used to control seizures)
•    digoxin (used to treat heart failure)
•    cyclosporine (used to lessen your body’s defenses)
•    quinidine and diltiazem (used to treat abnormal heart rhythms)
•    beta blockers and verapamil (used to treat high blood pressure)
•    morphine and other opioids (used to treat severe pain)

In particular, tell your doctor or pharmacist if you are taking any of the following medicines that increase your risk of bleeding: 

•    ‘oral anticoagulants’ often referred to as ʽblood thinners’ which include warfarin.
•    Non-Steroidal Anti-Inflammatory Drugs (abbreviated as NSAIDs) often taken as painkillers such as ibuprofen and naproxen.
•    Selective Serotonin Reuptake Inhibitors (abbreviated as SSRIs) taken as antidepressants such as paroxetine, sertraline and citalopram
•    Other medicines such as ketoconazole (used to treat fungal infections), clarithromycin (used to treat bacterial infections), nefazodone (an antidepressant), ritonavir and atazanavir (used to treat HIV infection and AIDS), cisapride (used to treat heartburn), ergot alkaloids (used to treat migraines and headaches).

Also tell your doctor that because you are taking Domassel, you may have an increased risk of bleeding if your doctor gives you fibrinolytics, often called ‘clot dissolvers’, such as streptokinase or alteplase. 
Pregnancy and breast-feeding 
It is not recommended to use Domassel if you are pregnant or may become pregnant. Women should use appropriate contraceptive measures to avoid pregnancy while taking this medicine. 
Talk to your doctor before taking this medicine if you are breast-feeding. Your doctor will discuss with you the benefits and risks of taking Domassel during this time.
