1. What is Xanirva and what is it used for

Xanirva contains the active substance rivaroxaban and is used in adults to:

• prevent blood clots in the brain (stroke) and other blood vessels in the body, if you have a type of irregular heartbeat called atrial fibrillation not caused by heart valve problems.
• treat blood clots in the veins of the legs (deep vein thrombosis) and in the blood vessels of the lungs (pulmonary embolism) and prevent blood clots from forming again in the legs and/or lungs.

Xanirva is used in children and adolescents under 18 years of age and weighing 30 kg or more to:

• treat and prevent blood clots in the veins or lungs after at least 5 days of initial treatment with injectable medicines used to treat blood clots.

Xanirva belongs to a group of medicines called anticoagulants. Its action is to block the blood clotting factor (factor Xa) and thus reduce the tendency to form blood clots.

2. Important information before taking Xanirva

When not to take Xanirva:

• -if you are allergic to rivaroxaban or any of the other ingredients of this medicine (listed in section 6);
• if you have excessive bleeding;
• if you have a disease or condition of an organ that increases the risk of serious bleeding (e.g., stomach ulcer, injury or bleeding in the brain, recent brain or eye surgery);

if you are taking other medicines to prevent blood clots (e.g., warfarin, dabigatran, apixaban, or heparin), except when switching anticoagulant therapy or when heparin is given to maintain catheter patency in a vein or artery;

Warnings and precautions

Before taking Xanirva, talk to your doctor or pharmacist.

When to be careful when taking Xanirva

• if you have an increased risk of bleeding, such as:
• severe kidney disease in adults and moderate or severe kidney disease in children and adolescents, as kidney function may affect the amount of medicine in the body;
• taking other medicines to prevent blood clots (e.g., warfarin, dabigatran, apixaban, or heparin) when switching anticoagulant therapy or when heparin is given to maintain catheter patency in a vein or artery (see "Other medicines and Xanirva");
• bleeding disorders;
• very high blood pressure that does not decrease despite treatment;
• stomach or intestinal diseases that may cause bleeding, such as inflammation of the intestines and stomach or esophageal inflammation (e.g., due to gastroesophageal reflux disease) or tumors in the stomach, intestines, genital, or urinary tract;
• vascular disease in the back of the eye (retinopathy);
• pulmonary disease with dilated bronchi and pus (bronchiectasis) or previous bleeding from the lungs;
• in patients with artificial heart valves;
• in patients with antiphospholipid syndrome (immune system disorders that increase the risk of blood clots). You should inform your doctor, who will decide whether to change treatment if necessary;
• if you have abnormal blood pressure or are scheduled for surgery or other treatment to remove a blood clot from the lungs.

If you suspect that what is written above applies to you, you should inform

your doctorbefore taking Xanirva. Your doctor will decide whether to use this medicine and whether you should be closely monitored.

If you are going to have surgery:

• it is very important to take Xanirva exactly as directed by your doctor before and after surgery;
• if catheterization or lumbar puncture is planned during surgery (e.g., for epidural or spinal anesthesia or pain relief):
• it is very important to take Xanirva exactly as directed by your doctor before and after the procedure;
• you should immediately inform your doctor if you experience numbness or weakness in your legs, bowel or bladder problems, as immediate treatment may be necessary.

3. How to take Xanirva

Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
Xanirva should be taken with food.
Swallow the capsule(s) whole with water.
If you have difficulty swallowing the whole capsule, talk to your doctor about other ways to take Xanirva. The contents of the capsule can be mixed with water or apple puree just before taking. After such a mixture, you should eat a meal immediately. If necessary, your doctor may also give the contents of the Xanirva capsule through a gastric tube.

How many capsules to take

o Adults

• -To prevent blood clots in the brain (stroke) and other blood vessels in the bodyThe recommended dose is one Xanirva 20 mg capsule once a day. If you have kidney problems, the dose may be reduced to one Xanirva 15 mg capsule once a day.

If you need a procedure to open up blood vessels in the heart (called percutaneous coronary intervention - PCI with stent placement), there is limited evidence to support a dose reduction to one Xanirva 15 mg capsule once a day (or one Xanirva 10 mg capsule once a day in case of kidney dysfunction) in combination with an antiplatelet medicine such as clopidogrel.

• -To treat blood clots in the veins of the legs, blood clots in the lungs, and to prevent blood clots from forming againThe recommended dose is one Xanirva 15 mg capsule twice a day for the first 3 weeks. For treatment after 3 weeks, the recommended dose is one Xanirva 20 mg capsule once a day. After at least 6 months of treatment for blood clots, your doctor may decide to continue treatment with either one 10 mg capsule once a day or one 20 mg capsule once a day. If you have kidney problems and are taking one Xanirva 20 mg capsule once a day, your doctor may decide to reduce the dose after 3 weeks of treatment to one Xanirva 15 mg capsule once a day if the risk of bleeding is higher than the risk of further blood clots.

o Children and adolescents
The dose of Xanirva depends on body weight and will be calculated by your doctor.

• The recommended dose for children and adolescents weighing 30 kg to less than 50 kgis one Xanirva 15 mg capsule once a day.
• The recommended dose for children and adolescents weighing 50 kg or moreis one Xanirva 20 mg capsule once a day.

Each dose of Xanirva should be taken with food, with a drink (e.g., water or juice). Capsules should be taken daily at approximately the same time. It's a good idea to set an alarm to remind you.
For parents or caregivers: you should observe the child to ensure they take the entire dose.
The dose of Xanirva is based on body weight, so it's essential to attend scheduled doctor's appointments, as the dose may need to be adjusted based on weight changes.
Never adjust the dose of Xanirva yourself. If necessary, your doctor will adjust the dose.
Do not sprinkle the contents of the capsule to get a partial dose. If a smaller dose is needed, you should use a different medicine containing rivaroxaban in the form of granules for oral suspension.
For children and adolescents who are unable to swallow whole capsules, you should use a medicine containing rivaroxaban in the form of granules for oral suspension.
If the oral suspension is not available, you can sprinkle the contents of the Xanirva capsule and mix it with water or apple puree just before taking. After such a mixture, you should eat a meal immediately. If necessary, your doctor may also give the sprinkled contents of the Xanirva capsule through a gastric tube.

If you spit out a dose or vomit

• less than 30 minutes after taking Xanirva, you should take a new dose.
• more than 30 minutes after taking Xanirva, do not takea new dose. In this case, take the next dose of Xanirva at the usual time.

You should contact your doctor if you spit out a dose or vomit repeatedly after taking Xanirva.

When to take Xanirva

Take the capsule(s) every day until your doctor decides to stop treatment.
It's best to take the capsule(s) at the same time every day, as it's easier to remember.
Your doctor will decide how long you should continue treatment.
To prevent blood clots in the brain (stroke) and other blood vessels in the body:
If your heart rhythm needs to be restored with a procedure called cardioversion, you should take Xanirva as directed by your doctor.

Taking a higher dose of Xanirva than recommended

If you take more Xanirva than recommended, you should contact your doctor immediately. Taking too much Xanirva increases the risk of bleeding.

Missing a dose of Xanirva

• Adults, children, and adolescents: If you take one 20 mg or one 15 mg capsule oncea day and miss a dose, you should take it as soon as possible. Do not take more than one capsule in a 24-hour period to make up for a missed dose. Take the next capsule at the usual time the next day and then continue taking one capsule once a day.

Adults:
If you take one 15 mg capsule twicea day and miss a dose, you should take it as soon as possible. Do not take more than two 15 mg capsules in a 24-hour period. If you miss a dose, you can take two 15 mg capsules at the same time to take a total of two capsules (30 mg) in a 24-hour period. The next day, continue taking one 15 mg capsule twice a day.

Stopping Xanirva treatment

You should not stop taking Xanirva without first talking to your doctor, as Xanirva treats and prevents serious diseases.
If you have any further questions about taking Xanirva, ask your doctor or pharmacist.
