1. Package contents and additional information

1. What is Tolvaptan Teva and what is it used for

The active substance of this medication 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, tolvaptan slows down the development of renal cysts in patients with ADPKD, reduces the symptoms of the disease, and increases urine production.

Tolvaptan is a medication 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, even leading to kidney failure. Tolvaptan is used to treat ADPKD in adults with chronic kidney disease (CKD) in stages 1 to 4 with signs of rapid disease progression.

2. What you need to know before taking Tolvaptan Teva

Do not take Tolvaptan Teva

• if you are allergic to tolvaptan or any of the other components of this medication (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 that this prevents you from receiving treatment with tolvaptan.
• if your kidneys do not function (no urine production).
• if you have a disorder associated with very low blood volume (e.g., severe dehydration or bleeding).
• if you have a disorder that increases the amount of sodium in your blood.
• if you do not feel the sensation of thirst.
• if you are pregnant.
• if you are breastfeeding.

Warnings and precautions

Consult your doctor before starting to take tolvaptan:

• 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 prostate hypertrophy (e.g., enlarged prostate).
• 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 components of this medication (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).
• if you have advanced kidney disease.

This medication 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
• pseudogrippal syndrome (muscle and joint pain with fever)

During treatment with this medication, your doctor will request monthly blood tests to monitor changes in your liver function.

Drinking enough water

This medication 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, 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 disease 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 important to always have a bathroom nearby.

Children and adolescents

Do not give this medication to children and adolescents (under 18 years) because it has not been studied in this population.

3. How to take Tolvaptan Teva

Only doctors specialized in the treatment of ADPKD can prescribe tolvaptan.

Follow the administration instructions of this medication exactly as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

Dose

The daily dose of tolvaptan should be divided into two doses, one higher than the other. The higher dose should be taken in the morning, 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, 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 medications that may increase the effects of tolvaptan, you may receive lower doses. In this case, your doctor may prescribe 30 or 15 mg tolvaptan tablets, which you should take once a day in the morning.

Method of administration

Swallow the tablets whole with a glass of water.

Tolvaptan Teva 15 mg tablets Tolvaptan Teva 15 mg + Tolvaptan Teva 45 mg tablets

The tablet can be divided into equal doses.

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

In case you have taken more tablets than the prescribed dose, drink plenty of water and contact your doctor or the nearest hospital immediately. Remember to bring the medication package with you so that it is clear what you have taken. If you take the higher dose too late, you may need to go to the bathroom more frequently at night.

In case of overdose or accidental ingestion, consult the Toxicology Information Service. Phone 91 562 04 20, indicating the medication and the amount taken. It is recommended to bring the packaging and the medication leaflet to the healthcare professional.

If you forget to take Tolvaptan Teva

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

If you stop treatment with Tolvaptan Teva
