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.

These medicines can affect or be affected by Jinarc:

• diuretics (used to influence the production of urine). Taken with Jinarc these may increase the risk of side effects due to water loss or may cause kidney problems.
• diuretics or other medicines for the treatment of high blood pressure. Taken with Jinarc these may increase the risk of low blood pressure when you stand up from sitting or lying down.
• medicines which increase the level of sodium in your blood or which contain large amounts of salt (e.g. tablets that dissolve in water and indigestion remedies). These may increase the effect of Jinarc. There is a risk that this may lead to too much sodium in your blood.

It may still be alright for you to take these medicines and Jinarc together. Your doctor will be able to decide what is suitable for you.

Do not drink grapefruit juice when taking this medicine.

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.
