2. What you need to know before you use Trepulmix

Do not use Trepulmix

• if you are allergic to treprostinil or any of the other ingredients of this medicine (listed in section 6);
• if you have been diagnosed with a disease called "pulmonary veno-occlusive disease"; this is a disease where the blood vessels that carry blood through the lungs become swollen and blocked, causing higher blood pressure in the blood vessels between the heart and lungs;
• if you have severe liver disease;
• if you have a heart problem, such as:

• a heart attack (myocardial infarction) in the last 6 months;
• severe irregular heartbeat;
• severe ischemic heart disease or unstable angina;
• a heart defect, such as a faulty heart valve that makes the heart work poorly;
• any heart disease that is not being treated or is not under close medical supervision.
• • if you have a high risk of bleeding, such as active stomach ulcers, wounds, or other bleeding conditions;
  • if you have had a stroke in the last 3 months or any other interruption of blood supply to the brain.

Warnings and precautions

Talk to your doctor before using Trepulmix if you:

• have liver disease;
• have kidney disease;
• have been told you are medically obese (BMI over 30 kg/m2);
• are on a low-sodium diet.

Tell your doctor while using Trepulmix:

• if your blood pressure drops (hypotension);
• if you experience a rapid increase in breathing difficulties or persistent cough (this may be related to congestion in the lungs, asthma, or other conditions), consult your doctor immediately;
• if you experience excessive bleeding, as treprostinil may increase the risk by preventing blood clotting.

Children and adolescents

Trepulmix should not be used in children and adolescents.

Other medicines and Trepulmix

• medicines that prevent blood clotting(anticoagulants) such as warfarin, heparin, or nitric oxide products;
• any non-steroidal anti-inflammatory drug (NSAID) (e.g., acetylsalicylic acid or ibuprofen);
• medicines that may increase or decrease the effects of Trepulmix (e.g., gemfibrozil, rifampicin, trimethoprim, deferasirox, phenytoin, carbamazepine, phenobarbital, hypericum), as your doctor may need to adjust the dose of Trepulmix.

3. How to use Trepulmix

Follow the instructions for administration of this medicine exactly as told by your doctor. If you are unsure, consult your doctor again.

Trepulmix is administered undiluted by continuous subcutaneous infusion (under the skin) through a small tube (cannula) in your abdomen or thigh;

Trepulmix is driven through the tube by a portable pump.

Before you leave the hospital or clinic, your doctor will tell you how to prepare Trepulmix and the rate at which the pump should deliver treprostinil. They will also provide information on how to use the pump correctly and what to do if it stops working. Additionally, they will inform you of who to contact in case of an emergency.

Flushing the infusion line while it is connected can cause an accidental overdose.

Adult patients

Trepulmix is available as a solution for infusion of 1 mg/ml, 2.5 mg/ml, 5 mg/ml, or 10 mg/ml. Your doctor will determine the infusion rate and dose suitable for your condition.

Elderly patients

No special dose adjustment is needed in these patients.

Patients with severe liver or kidney disease

Your doctor will determine the infusion rate and dose suitable for your condition.

Infusion rate

The infusion rate can be reduced or increased individually only under medical supervision.

The goal of adjusting the infusion rate is to establish an effective maintenance rate that improves symptoms of CTEPH while minimizing adverse reactions.

If your symptoms worsen or if you need to rest completely, or if you are confined to bed or a chair, or if any physical activity causes discomfort and you experience symptoms at rest, do not increase the dose without consulting a doctor. It may be that Trepulmix is no longer sufficient to treat your disease and that you require other treatment.

If you use more Trepulmix than you should

If you accidentally overdose on Trepulmix, you may experience nausea, vomiting, diarrhea, low blood pressure (dizziness, lightheadedness, or fainting), flushing of the skin, and/or headaches.

If any of these effects worsen, you should contact your doctor or hospital immediately. Your doctor may reduce or interrupt the infusion until your symptoms have disappeared. The Trepulmix solution for infusion will be reintroduced at the dose recommended by your doctor.

If you stop using Trepulmix

Always use Trepulmix following the instructions of your doctor or hospital specialist. Do not stop using Trepulmix unless your doctor has advised you to do so.

Sudden withdrawal or rapid reduction of the dose of Trepulmix can cause pulmonary hypertension to return, with the possibility of rapid and severe worsening of your condition.

If you have any further questions on the use of this medicine, ask your doctor.
