1. What Xeplion is and what it is used for

Xeplion contains the active substance paliperidone, which belongs to a class of medicines called antipsychotics, and is used as maintenance treatment for symptoms of schizophrenia in adult patients who have been stabilized with paliperidone or risperidone.

If you have shown a response to paliperidone or risperidone in the past and have mild or moderate symptoms, your doctor may start treatment with Xeplion without prior stabilization with paliperidone or risperidone.

Schizophrenia is a disorder with "positive" and "negative" symptoms. Positive means an excess of symptoms that are not normally present. For example, a person with schizophrenia may hear voices or see things that do not exist (called hallucinations), have false beliefs (called delusions), or have an abnormal distrust of others. Negative refers to the lack of behaviors or feelings that are normally present. For example, a person with schizophrenia may withdraw into themselves and not respond to any emotional stimulus or may have problems speaking in a clear and logical manner. People with this disorder may also feel depressed, anxious, guilty, or tense.

Xeplion can help alleviate the symptoms of your illness and prevent them from coming back.

2. What you need to know before you use Xeplion

Do not use Xeplion

• if you are allergic to paliperidone or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic to any other antipsychotic medicine, including risperidone.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before you start using Xeplion.

This medicine has not been studied in elderly patients with dementia. However, elderly patients with dementia who are being treated with other similar medicines may have an increased risk of stroke or death (see section 4, possible side effects).

All medicines can cause side effects, and some of the side effects of this medicine may worsen the symptoms of other conditions. For this reason, it is important that you discuss with your doctor any of the following conditions that may worsen during treatment with this medicine:

• if you have Parkinson's disease
• if you have ever been diagnosed with a condition whose symptoms include high temperature and muscle stiffness (also known as Neuroleptic Malignant Syndrome)

• if you have ever experienced abnormal movements of the tongue or face (Tardive Dyskinesia)
• if you have had low white blood cell counts in the past (which may or may not have been caused by other medicines)
• if you are diabetic or have a tendency to diabetes
• if you have had breast cancer or a tumor in the pituitary gland of the brain

• if you have any heart disease or are being treated for heart diseases that may make you more prone to a decrease in blood pressure
• if you have low blood pressure when standing up or getting up suddenly
• if you have epilepsy
• if you have kidney problems

• if you have liver problems
• if you have a prolonged and/or painful erection

• if you have difficulty controlling body temperature or are overheated
• if you have an abnormally high level of the hormone prolactin in your blood or if you have a tumor that may be dependent on prolactin
• if you or someone in your family has a history of blood clots, as antipsychotics have been associated with the formation of blood clots.

If you have any of these conditions, please consult your doctor, as it may be necessary to adjust your dose or keep you under observation for a period of time.

Because it has been rarely observed in patients treated with this medicine that there is a dangerously low number of a type of white blood cell necessary to fight infections in the blood, your doctor may check your white blood cell count.

Even if you have previously tolerated oral paliperidone or risperidone, rare allergic reactions may occur after receiving Xeplion injections. Seek medical help immediately if you experience a skin rash, swelling of the throat, itching, or breathing problems, as these may be signs of a severe allergic reaction.

This medicine may cause you to gain weight. Significant weight gain can negatively affect your health. Your doctor will regularly monitor your weight.

In patients treated with this medicine, diabetes mellitus or worsening of pre-existing diabetes mellitus has been observed, and your doctor should check for signs of high blood sugar. In patients with pre-existing diabetes mellitus, blood sugar should be regularly monitored.

Since this medicine can reduce the urge to vomit, there is a possibility that it may mask the normal response of the body to the ingestion of toxic substances or other conditions.

During eye surgery for cataracts, the pupil (the black circle in the middle of the eye) may not increase in size as needed. Additionally, the iris (the colored part of the eye) may become flaccid during surgery, which can cause damage to the eye. If you are planning to have eye surgery, make sure to inform your ophthalmologist that you are using this medicine.

Children and adolescents

Do not use this medicine in children under 18 years of age.

Using Xeplion with other medicines

Tell your doctor if you are using, have recently used, or might use any other medicines.

Taking this medicine with carbamazepine (an antiepileptic and mood stabilizer) may require a change in your dose of this medicine.

Since this medicine acts mainly on the brain, interaction with other medicines that also act on it may cause an exaggeration of side effects, such as drowsiness or other effects on the brain, such as other psychiatric medicines, opioids, antihistamines, and sleeping medicines.

Since this medicine can lower blood pressure, you should be careful if you use this medicine with other medicines that also lower blood pressure.

This medicine may reduce the effect of medicines for Parkinson's disease and restless legs syndrome (e.g., levodopa).

This medicine may cause an abnormality in the electrocardiogram (ECG) that shows that it is necessary for an electrical impulse to travel through a certain part of the heart for a longer period (known as "prolongation of the QT interval"). Other medicines that have this effect include some medicines used to treat heart rhythm or to treat infections, in addition to other antipsychotics.

If you are prone to seizures, this medicine may increase your chances of experiencing them. Other medicines that have this effect include some medicines used to treat depression or to treat infections, in addition to other antipsychotics.

Xeplion should be used with caution with medicines that increase the activity of the central nervous system (psychostimulants such as methylphenidate).

Xeplion with alcohol

Alcohol should be avoided.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. You should not use this medicine during pregnancy unless you have discussed it with your doctor. The following symptoms may occur in newborn babies of mothers who have been treated with paliperidone in the last trimester of pregnancy (the last three months of pregnancy): tremors, stiffness and/or muscle weakness, drowsiness, agitation, breathing problems, and difficulty feeding. If your baby develops any of these symptoms, you should contact your doctor.

This medicine can pass from mother to child through breast milk and may harm the baby. Therefore, you should not breastfeed while using this medicine.

Detailed information on this medicinal product is available on the European Medicines Agency website: http://www.ema.europa.eu

This information is intended only for healthcare professionals and should be read in conjunction with the full prescribing information (Summary of Product Characteristics).

The injectable suspension is for single use. It should be visually inspected for any foreign particles before administration. Do not use the product if the syringe is not visually free from foreign particles.

The container contains a pre-filled syringe and two safety needles (one 22-gauge, 1½-inch [38.1 mm x 0.72 mm] needle and one 23-gauge, 1-inch [25.4 mm x 0.64 mm] needle) for intramuscular injection. Xeplion is also available in a Treatment Initiation Kit containing two pre-filled syringes (150 mg + 100 mg) and two additional safety needles.

1. 22-gauge x 1½” (Grey coloured hub)
2. 23-gauge x 1” (Blue coloured hub)
3. Pre-filled syringe

1. Hub
2. Needle shield

1. Shake the syringe vigorously for at least 10 seconds to ensure a homogeneous suspension.

1. Select the appropriate needle.

The first initiation dose of Xeplion (150 mg) is administered on Day 1 in the DELTOID muscle using the needle for DELTOID injection. The second initiation dose of Xeplion (100 mg) is also administered in the DELTOID muscle one week later (Day 8) using the needle for DELTOID injection.

If a patient is switched from prolonged-release injectable risperidone to Xeplion, the first Xeplion injection (dose range of 25 mg to 150 mg) may be administered in the DELTOID muscle or the GLUTEAL muscle, using the appropriate needle for the injection site, at the time of the next scheduled injection.

Subsequent monthly maintenance injections may be administered in either the DELTOID muscle or the GLUTEAL muscle using the appropriate needle for the injection site.

In the case of DELTOID injection, if the patient weighs < 90 kg, use the 23-gauge, 1-inch (25.4 mm x 0.64 mm) needle (needle with blue coloured hub); if the patient weighs ≥ 90 kg, use the 22-gauge, 1½-inch (38.1 mm x 0.72 mm) needle (needle with grey coloured hub).

In the case of GLUTEAL injection, use the 22-gauge, 1½-inch (38.1 mm x 0.72 mm) needle (needle with grey coloured hub).

1. While holding the syringe in a vertical position, remove the rubber shield from the needle with a twisting motion.

1. Open the blister pack of the safety needle halfway. Hold the needle cover by the plastic paper of the pack that you just opened. Attach the safety needle to the Luer connection of the syringe with a simple clockwise twisting motion.

1. Pull the sheath straight to separate it from the needle. Do not twist the sheath, as the needle may loosen from the syringe.

1. Hold the syringe with the needle in place in a vertical position to proceed with the elimination of air. Eliminate the air from the syringe by carefully pushing the plunger forward.

1. Inject the entire contents intramuscularly, slowly, and deeply into the selected DELTOID or GLUTEAL muscle of the patient. Do not administer intravascularly or subcutaneously.

1. Once the injection is complete, use your thumb or other finger (8a, 8b) or a flat surface (8c) to activate the needle protection system. The system is fully activated when you hear a click. Dispose of the syringe with the needle in an appropriate manner.
