1. What is Jinarc and what is it used for

Jinarc is a medicine used to treat a disease known as "autosomal dominant polycystic kidney disease" (ADPKD). This disease leads to the development of fluid-filled cysts in the kidneys, which can cause pressure on the surrounding tissues and reduce kidney function, potentially leading to kidney failure. Jinarc is used to treat ADPKD in adults with chronic kidney disease (CKD) stage 1 to 4 with signs of rapid disease progression.

The active substance in Jinarc is tolvaptan, which blocks the effect of vasopressin, a hormone involved in the formation of cysts in the kidneys of patients with ADPKD. By blocking the effect of vasopressin, Jinarc slows the development of kidney cysts in patients with ADPKD, reduces the symptoms of the disease, and increases urine production.

2. What you need to know before you take Jinarc

Do not take Jinarc:

• If you are allergic to tolvaptan or any of the other ingredients of this medicine (listed in section 6) or if you are allergic to benzazepine or benzazepine derivatives (e.g., benazepril, conivaptan, fenoldopam mesylate, or mirtazapine).

• If you have been told that you have elevated liver enzyme levels in your blood and this prevents you from receiving treatment with tolvaptan.
• If your kidneys do not function (no urine production)
• If you have a condition associated with very low blood volume (e.g., severe dehydration or bleeding).
• • If you have a condition that increases the amount of sodium in your blood.
  • If you do not feel thirsty.
  • If you are pregnant (see "Pregnancy and breastfeeding").
  • If you are breastfeeding (see "Pregnancy and breastfeeding").

Warnings and precautions

Consult your doctor before starting to take Jinarc:

• If you have liver disease.

• If you cannot drink enough water (see "Drinking enough water" below) or if you need to limit your fluid intake.
• • If you have difficulty urinating or benign prostatic hyperplasia (enlargement of the prostate gland).
  • If you have elevated or decreased sodium levels in your blood.
• If you have had an allergic reaction to benzazepine, tolvaptan, or other benzazepine derivatives (e.g., benazepril, conivaptan, fenoldopam mesylate, or mirtazapine) or to any of the other ingredients of this medicine (listed in section 6).
• • If you have diabetes.
  • If you have been told that you have elevated uric acid levels in your blood (which may have caused gout).

Jinarc may cause your liver to not function properly. For this reason, please inform your doctor immediately if you experience signs that may indicate liver problems, such as:

• nausea
• vomiting
• fever
• fatigue
• loss of appetite
• abdominal pain
• dark urine
• jaundice (yellowing of the skin or eyes)
• itching (pruritus) of the skin
• pseudo-flu syndrome (muscle and joint pain with fever)

During treatment with Jinarc, your doctor will ask you to have monthly blood tests to monitor changes in your liver function.

Drinking enough water

Jinarc causes water loss because it increases urine production. This water loss can lead to side effects such as dry mouth and thirst or even more serious side effects such as kidney problems (see section 4). Therefore, it is essential that you have access to water and can drink enough fluids when you feel thirsty. Before going to bed, you should drink one or two glasses of water, even if you do not feel thirsty, and also drink water after urinating at night. You should be particularly careful if you have a condition that reduces adequate fluid intake or if you are at higher risk of dehydration, for example, if you have vomiting or diarrhea. Due to the increased urine production, it is also essential to always have a bathroom nearby.

Children and adolescents

Jinarc has not been studied in children and adolescents (under 18 years) and, therefore, is not recommended for use in this population.

Other medicines and Jinarc

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription.

In particular, inform your doctor if you are taking:

• treatments containing ketoconazole for fungal infections, macrolide antibiotics such as clarithromycin, or diltiazem for treating high blood pressure and chest pain.
• These medicines may increase the effects of Jinarc.
• medicines that increase sodium levels in the blood or contain large amounts of salt, such as effervescent tablets and antacids. These may increase the effects of Jinarc.
• digoxin (a medicine for treating irregular heartbeat and heart failure), dabigatran (used as a blood anticoagulant), rosuvastatin or pitavastatin (used to lower cholesterol levels in the blood), methotrexate (used to treat cancer and arthritis), ciprofloxacin (an antibiotic), sulfasalazine (for treating irritable bowel disease or rheumatoid arthritis), or metformin (for treating diabetes). Jinarc may increase the effect of these medicines.
• phenytoin or carbamazepine (medicines for treating epilepsy), rifampicin (a medicine for treating tuberculosis), or St. John's Wort (a herbal medicine for mild depression and anxiety). It is best to avoid using any of these medicines in combination with Jinarc, as they may reduce the effects of Jinarc.
• diuretics (used to increase urine production). When taken at the same time as Jinarc, these medicines may increase the risk of side effects due to water loss.
• diuretics or other medicines for treating high blood pressure. When taken at the same time as Jinarc, these medicines may increase the risk of low blood pressure when standing up or getting up.
• desmopressin (used to increase blood clotting factors or to control urine production or incontinence). Jinarc may reduce the effect of desmopressin.

It may not be a problem to take these medicines at the same time as Jinarc. Your doctor will decide what is best for you.

Using Jinarc with drinks and alcohol

Do not drink grapefruit juice while taking Jinarc.

Pregnancy and breastfeeding

Do nottake this medicine if you are pregnant or breastfeeding.

Women of childbearing potential should use reliable contraceptive methods while being treated with this medicine.

If you are pregnant or breastfeeding, or think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Some people may feel dizzy, weak, or tired after taking Jinarc. If you experience these effects, do not drive or use tools or machines.

3. How to take Jinarc

Only specialized doctors in the treatment of ADPKD can prescribe Jinarc. Follow your doctor's instructions for taking this medicine exactly. If you are unsure, consult your doctor or pharmacist again.

Dose

The daily dose of Jinarc should be divided into two doses, one higher than the other. The higher dose should be taken in the morning when you get up, at least 30 minutes before breakfast, while the lower dose should be taken 8 hours later.

The dose combinations are:

45 mg + 15 mg

60 mg + 30 mg

90 mg + 30 mg

Normally, your treatment will start with a dose of 45 mg in the morning and 15 mg 8 hours later. Your doctor may gradually increase your dose up to a maximum combination of 90 mg in the morning and 30 mg 8 hours later. To determine the best dose for you, your doctor will regularly check how you tolerate the prescribed dose. You should always take the highest tolerable dose combination prescribed by your doctor.

If you are taking other medicines that may increase the effects of Jinarc, you may receive lower doses. In this case, your doctor may prescribe Jinarc tablets with 30 or 15 mg of tolvaptan, which you should take once a day in the morning.

Method of administration

Swallow the tablets whole with a glass of water.

The morning dose should be taken at least 30 minutes before breakfast. The second daily dose can be taken with or without food.

If you take more Jinarc than you should

If you have taken more tablets than prescribed, drink plenty of water and contact your doctor or the nearest hospital immediately.Remember to take the package leaflet with you to show what you have taken. If you take the higher dose too late, you may need to go to the bathroom more frequently at night.

If you forget to take Jinarc

If you forget to take your medicine, take the dose as soon as you remember on the same day. If you have not taken the tablets for one day, take the normal dose the next day. Do nottake a double dose to make up for the missed individual doses.

If you stop taking Jinarc

If you stop taking Jinarc, your kidney cysts may grow as quickly as they did before you started treatment with this medicine. Therefore, you should only stop taking Jinarc if you experience side effects that require urgent medical attention (see section 4) or if your doctor tells you to do so.

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