1. What is Treprostinil Dr. Reddys and what is it used for

The active substance of this medicine is treprostinil.

Treprostinil belongs to a group of medicines whose action is similar to that of natural prostacyclins. Prostacyclins are hormone-like substances that reduce blood pressure by relaxing blood vessels, so they widen and allow blood to flow more easily. Prostacyclins can also prevent blood clotting.

What is treprostinil used for

Treprostinil is used to treat idiopathic or hereditary pulmonary arterial hypertension (PAH) in patients with moderate symptoms. Pulmonary arterial hypertension is a disease in which blood pressure is too high in the blood vessels between the heart and lungs. This causes difficulty breathing, dizziness, fatigue, fainting, palpitations or abnormal heartbeats, dry cough, chest pain, and swelling of ankles or legs.

Treprostinil Dr. Reddys is initially administered by continuous subcutaneous infusion (under the skin). Some patients may not tolerate this administration because it causes local pain and swelling. The doctor will decide if you can be administered Treprostinil Dr. Reddys through continuous intravenous infusion directly into a vein with the insertion of a central venous tube (catheter) connected to an external pump or, depending on your condition, a surgically implanted pump under the skin of your abdomen. Your doctor will determine the best option for you.

How treprostinil works

Treprostinil reduces blood pressure in the pulmonary artery by improving circulation and reducing the heart's workload. Improved blood circulation increases oxygen supply to the body and requires less effort from the heart, so it works more efficiently. Treprostinil improves symptoms associated with PAH and exercise capacity in patients with reduced activity.

2. What you need to know before taking Treprostinil Dr. Reddys

Do not use Treprostinil Dr. Reddys:

• if you are allergic to treprostinil or any of the other components of this medicine (listed in section 6);
• if you have been diagnosed with a disease called "pulmonary veno-occlusive disease". In this disease, the blood vessels that carry blood through the lungs become swollen and blocked, increasing pressure in the blood vessels between the heart and lungs;
• if you have severe liver failure;
• if you have a heart problem, such as:
• • a heart attack in the last six months
  • severe changes in heart rate
  • severe coronary heart disease or unstable angina
  • a diagnosed heart defect, such as a defective heart valve that causes the heart to malfunction
  • any untreated or closely monitored heart disease;

• if you have a high specific risk of bleeding, such as active stomach ulcers, injuries, or other bleeding disorders;
  • if you have had a stroke in the last three months or any interruption of blood supply to the brain.

Warnings and precautions

Consult your doctor before starting to use Treprostinil Dr. Reddys:

• if you have any liver disease
• if you have been told that you are clinically obese (BMI greater than 30 kg/m2)
• if you have human immunodeficiency virus (HIV) infection
• if you have high blood pressure in the liver veins (portal hypertension)
• if you have a congenital heart defect that affects how blood circulates through it

During treatment with this medicine, inform your doctor:

• if your blood pressure drops (hypotension)
• if you experience a rapid increase in breathing difficulties or persistent cough (may be related to pulmonary congestion, asthma, or other disease), consult your doctor immediately.
• if you experience excessive bleeding, as treprostinil may increase the risk by preventing blood clotting.
• if you have a fever while receiving treprostinil intravenously, or if the intravenous administration site becomes red, swollen, or painful to the touch, as it may be a symptom of infection.

Using Treprostinil Dr. Reddys with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.

Tell your doctor if you are taking:

• medicines to treat high blood pressure(antihypertensive medicines or other vasodilators)
• medicines used to increase the amount of urine excreted(diuretics), including furosemide
• medicines that interrupt blood clotting(anticoagulants), such as products containing warfarin, heparin, or nitric oxide
• any non-steroidal anti-inflammatory drug (NSAID) (such as acetylsalicylic acid or ibuprofen)
• medicines that may increase or decrease the effect of treprostinil (such as gemfibrozil, rifampicin, trimethoprim, deferasirox, phenytoin, carbamazepine, phenobarbital, St. John's Wort), as the doctor may need to adjust the dose of treprostinil.

3. How to use Treprostinil Dr. Reddys

Follow your doctor's instructions for administering this medicine exactly. If in doubt, consult your doctor again.

Treprostinil Dr. Reddys is administered as a continuous infusion:

• Subcutaneously (under the skin) through a small tube (cannula) placed in the abdomen or thigh; or,
• Intravenously through a tube (catheter) that is normally placed in the neck, chest, or groin.

For subcutaneous infusion, the product should be administered undiluted.

For intravenous infusion, the product should be diluted according to the prescriber's instructions and can only be diluted with sterile water for injection or a 0.9% (w/v) sodium chloride injection solution.

In both cases, Treprostinil Dr. Reddys will be driven through the tube by a portable pump that is placed outside your body (external).

Before leaving the hospital or clinic, your doctor will tell you how to prepare Treprostinil Dr. Reddys and at what speed the pump should administer Treprostinil Dr. Reddys.

Flushing the infusion tube while connected can cause an accidental overdose.

Alternatively, Treprostinil Dr. Reddys can be administered intravenously through an implantable infusion pump that is usually surgically inserted under the skin of your abdomen. In this case, the pump and tube are completely inside your body (internal) and you will need to go to the hospital periodically (e.g., every 4 weeks) to have the internal reservoir refilled.

In any case, you will also be given information on how to use the pump correctly and what to do if it stops working. The information should also tell you who to contact in case of an emergency.

Treprostinil Dr. Reddys is diluted only when administered with continuous intravenous infusion:

For intravenous infusion with an external portable pump:You should only dilute your Treprostinil Dr. Reddys solution with sterile water for injection or 0.9% sodium chloride injection solution (as indicated by your doctor).

For intravenous infusion with an implantable infusion pump:You should go to the hospital periodically (e.g., every 4 weeks) where your doctor will dilute your Treprostinil Dr. Reddys solution with 0.9% sodium chloride injection solution and refill the internal reservoir.

Adult patients

Treprostinil Dr. Reddys 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 suitable dose for your disease.

Overweight patients

If you are overweight (weigh 30% or more of your ideal body weight), your doctor will determine the initial and subsequent doses based on your ideal body weight. See section 2, "Warnings and precautions".

Elderly patients

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

Dose adjustment

The infusion rate in each individual patient may be reduced or increased only under medical supervision.

The goal of adjusting the infusion rate is to establish an effective maintenance rate that improves PAH symptoms while minimizing side effects.

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

How can bloodstream infections be avoided during intravenous administration of treprostinil?

As with all long-term intravenous treatments, there is a risk of contracting a bloodstream infection. Your doctor will tell you how to avoid them.

If you use more Treprostinil Dr. Reddys than you should

If treprostinil is accidentally administered in excess, you may experience nausea, vomiting, diarrhea, low blood pressure (dizziness, drowsiness, or fainting), flushing, or headache.

If any of these symptoms become severe, you should contact your doctor or hospital immediately. The doctor may reduce the dose or interrupt administration until the symptoms disappear. Then, the administration of treprostinil will be resumed with the dose recommended by your doctor.

In case of overdose, consult your doctor immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount used.

If you stop treatment with Treprostinil Dr. Reddys

Always use treprostinil as indicated by your doctor or hospital specialist. Do not stop using treprostinil unless your doctor tells you to.
