Patient leaflet - Xanirva 10 mg hard capsules
1. What Xanirva is and what it is used for
Xanirva contains the active substance rivaroxaban and is used in adults to
- prevent blood clots in the veins after a hip or knee replacement operation. Your doctor has prescribed this medicine for you because after an operation you are at an increased risk of getting blood clots.
- treat blood clots in the veins of your legs (deep vein thrombosis) and in the blood vessels of your lungs (pulmonary embolism), and to prevent blood clots from re-occurring in the blood vessels of your legs and/or lungs.
Xanirva belongs to a group of medicines called antithrombotic agents. It works by blocking a blood clotting factor (factor Xa) and thus reducing the tendency of the blood to form clots.
2. What you need to know before you take Xanirva
Do not take Xanirva:
- if you are allergic to rivaroxaban or any of the other ingredients of this medicine (listed in section 6)
- if you are bleeding excessively
- if you have a disease or condition in an organ of the body that increases the risk of serious bleeding (e.g. stomach ulcer, injury or bleeding in the brain, recent surgery of the brain or eyes)
- if you are taking medicines to prevent blood clotting (e.g. warfarin, dabigatran, apixaban or heparin), except when changing anticoagulant treatment or while getting heparin through a venous or arterial line to keep it open
- if you have a liver disease which leads to an increased risk of bleeding
- if you are pregnant or breast-feeding
Do not take Xanirva and tell your doctor if any of these apply to you.
Warnings and precautions
Talk to your doctor or pharmacist before taking Xanirva.
Take special care with Xanirva:
if you have an increased risk of bleeding, as could be the case in situations such as:
- moderate or severe kidney disease, since your kidney function may affect the amount of medicine that works in your body
- if you are taking other medicines to prevent blood clotting (e.g. warfarin, dabigatran, apixaban or heparin), when changing anticoagulant treatment or while getting heparin through a venous or arterial line to keep it open (see section “Other medicines and Xanirva”)
- bleeding disorders
- very high blood pressure, not controlled by medical treatment
- diseases of your stomach or bowel that might result in bleeding, e.g. inflammation of the bowels or stomach, or inflammation of the oesophagus (gullet) e.g. due to gastroesophageal reflux disease (disease where stomach acid goes upwards into the oesophagus) or tumours located in the stomach or bowels or genital tract or urinary tract
- a problem with the blood vessels in the back of your eyes (retinopathy)
- a lung disease where your bronchi are widened and filled with pus (bronchiectasis), or previous bleeding from your lung
- if you have a prosthetic heart valve
- if you know that you have a disease called antiphospholipid syndrome (a disorder of the immune system that causes an increased risk of blood clots), tell your doctor who will decide if the treatment may need to be changed
- if your doctor determines that your blood pressure is unstable or another treatment or surgical procedure to remove the blood clot from your lungs is planned.
If any of the above apply to you, tell your doctor before you take Xanirva. Your doctor will decide, if you should be treated with this medicine and if you should be kept under closer observation.
If you need to have an operation:
- it is very important to take Xanirva before and after the operation exactly at the times you have been told by your doctor.
if your operation involves a catheter or injection into your spinal column (e.g. for epidural or spinal anaesthesia or pain reduction):
- it is very important to take Xanirva exactly at the times you have been told by your doctor
- tell your doctor immediately if you get numbness or weakness of your legs or problems with your bowel or bladder after the end of anaesthesia, because urgent care is necessary.

Pregnancy and breast-feeding
Do not take Xanirva if you are pregnant or breast-feeding. If there is a chance that you could become pregnant, use a reliable contraceptive while you are taking Xanirva.

Xanirva contains lactose monohydrate (a type of sugar) and sodium

3. How to take Xanirva
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
How much to take
To prevent blood clots in the veins after a hip or knee replacement operation
The recommended dose is one capsule Xanirva 10 mg once a day.
To treat blood clots in the veins of your legs and blood clots in the blood vessels of your lungs, and for preventing blood clots from re-occurring
After at least 6 months blood clot treatment, the recommended dose is either one 10 mg capsule once a day or one 20 mg capsule once a day. Your doctor has prescribed you Xanirva 10 mg once a day.
Swallow the capsule preferably with water.
Xanirva can be taken with or without food.
If you have difficulty swallowing the capsule whole, talk to your doctor about other ways to take Xanirva. The content of the capsule may be mixed with water or apple puree immediately before you take it.
If necessary, your doctor may also give you the sprinkled Xanirva capsule content through a stomach tube.
When to take Xanirva
Take the capsule every day until your doctor tells you to stop.
Try to take the capsule at the same time every day to help you to remember it.
Your doctor will decide how long you must continue treatment.
To prevent blood clots in the veins after a hip or knee replacement operation:
Take the first capsule 6 - 10 hours after your operation.
If you have had a major hip operation you will usually take the capsules for 5 weeks.
If you have had a major knee operation you will usually take the capsules for 2 weeks.
If you take more Xanirva than you should
Contact your doctor immediately if you have taken too many Xanirva capsules. Taking too much Xanirva increases the risk of bleeding.
If you forget to take Xanirva
If you have missed a dose, take it as soon as you remember. Take the next capsule on the following day and then carry on taking a capsule once a day as normal.
Do not take a double dose to make up for a forgotten capsule.
If you stop taking Xanirva
Do not stop taking Xanirva without talking to your doctor first, because Xanirva prevents the development of a serious condition.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
