Jinarc contains the active substance tolvaptan which blocks the effect of vasopressin, a hormone involved in the formation of cysts in the kidneys of ADPKD patients. By blocking the effect of vasopressin, Jinarc slows the development of kidney cysts in patients with ADPKD, reduces symptoms of the disease and increases urine production.
Jinarc is a medicine used to treat a disease called “autosomal dominant polycystic kidney disease” (ADPKD). This disease causes growth of fluid-filled cysts in the kidneys, which put pressure on surrounding tissues and reduce kidney function, possibly leading to kidney failure. Jinarc is used to treat ADPKD in adults with chronic kidney disease (CKD) stages 1 to 4 with evidence of rapidly progressing disease.
Talk to your doctor before taking Jinarc
Drinking enough water
This medicine causes water loss because it increases your urine production. This water loss may result in side effects such as dry mouth and thirst or even more severe side effects like kidney problems (see section 4). It is therefore important that you have access to water and that you are able to drink sufficient amounts when you feel thirsty. Before bed-time you must drink 1 or 2 glasses of water even if you do not feel thirsty and you must also drink water after you urinate at night. Special care must be taken if you have a disease that reduces appropriate fluid intake or if you are at an increased risk of water loss e.g. in case of vomiting or diarrhoea. Due to the increased urine production, it is also important that you always have access to a toilet.
Do not give this medicine to children and adolescents (under age of 18 years) because it has not been studied in these age groups.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

Dose
The daily amount of Jinarc is split into two doses, one bigger than the other. The higher dose should be taken in the morning when you wake up, at least 30 minutes before the morning meal. The lower dose is taken 8 hours later.
The dose combinations are:
45 mg + 15 mg
60 mg + 30 mg
90 mg + 30 mg
Your treatment will normally 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 on waking and 30 mg after 8 hours. To find the best dose your doctor will regularly check how well you are tolerating a prescribed dose. You should always take the highest tolerable dose combination prescribed by your doctor.
If you take other medicines, which can increase the effects of Jinarc you may receive lower doses. In this case your doctor may prescribe you Jinarc tablets with 30 mg or 15 mg tolvaptan which have to be taken once a day in the morning.
Method of administration
Swallow the tablets without chewing, with a glass of water.
The morning dose is to be taken at least 30 minutes before the morning meal. The second daily dose can be taken with or without food.
If you have taken more tablets than your prescribed dose, drink plenty of water and contact your doctor or your local hospital immediately. Remember to take the medicine pack with you so that it is clear what you have taken. If you take the higher dose very late in the day you may have to go to the toilet at night more frequently.
If you forget to take your medicine, you should take the dose as soon as you remember on the same day. If you do not take your tablets on one day, take your normal dose on the next day. DO NOT take a double dose to make up for forgotten individual doses.
If you stop taking this medicine your kidney cysts may grow as fast as they did before you started treatment with Jinarc. Therefore, you should only stop taking this medicine if you notice side effects requiring urgent medical attention (see section 4) or if your doctor tells you to.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
