Your nephrologist or healthcare provider will closely monitor your liver function while you take tolvaptan. For your safety, you must enroll in the Tolvaptan for ADPKD Shared System REMS and undergo regular blood tests. This helps reduce the risk of developing liver problems during treatment.

How to Participate

Before treatment, work with your healthcare provider to:

Complete the enrollment form for the 
Tolvaptan for ADPKD Shared System 
REMS together.
Sign up to have your prescriptions for tolvaptan 
tablets delivered from a certified pharmacy 
participating in the Tolvaptan for ADPKD 
Shared System REMS.

Contact the REMS call center number at +1 (866) 244-9446 to sign up by phone or visit Tolvaptan for ADPKD Shared System REMS at www.TolvaptanADPKDSharedREMS.com to enroll online.

How to Monitor

To reduce your risk of liver problems, your healthcare provider will routinely do blood tests to check your liver:

  • before you start taking tolvaptan tablets,

  • at 2 weeks and 4 weeks after you start treatment,

  • then monthly for 18 months during treatment,

  • and every 3 months from then on.

Schedule for Liver Health Blood Tests

It is important to complete all the required blood testing while on treatment.

What to Watch For

While on treatment, watch for any signs of liver problems and inform your healthcare provider if you notice anything unusual:

Taking Your Tolvaptan Medicine

Tolvaptan tablets are used to slow kidney function decline in adults at risk of rapidly progressing ADPKD.

The starting dose for tolvaptan tablets is 60 mg daily.

Your healthcare provider may adjust your tolvaptan dose over time 
to help you get the best results from this medicine.

Tablets are taken orally (by mouth) 2 times each day as instructed by your healthcare provider.

Take the first dose when 
you wake up and take the 
second dose 8 hours later. 

  • Following this schedule ensures 
    the medicine works throughout 
    the day and reduces the need 
    to wake up at night to urinate.

Take your medicine with or 
without food.

Be sure to drink enough water 
throughout the day so that you 
will not get thirsty or become 
dehydrated.

Do not eat grapefruit or drink 
grapefruit juice while on 
tolvaptan, as this could 
cause you to have too much 
tolvaptan in your blood.

If you miss a dose of tolvaptan tablets, take the next dose at your usual time (do not double up on doses).

There are 3 dose combinations of tolvaptan tablets available that are provided as weekly blister packs, with the morning and afternoon doses clearly marked.

INDICATION and IMPORTANT SAFETY INFORMATION

Tolvaptan tablets are indicated to slow kidney function decline in adults at risk of rapidly progressing autosomal dominant polycystic kidney disease (ADPKD).

WARNING: RISK OF SERIOUS LIVER INJURY 
  • Tolvaptan tablets can cause serious and potentially fatal liver injury. Acute liver failure requiring liver transplantation has been reported 

  • Measure transaminases (ALT, AST) and bilirubin before initiating treatment, at 2 weeks and 4 weeks after initiation, then monthly for the first 18 months and every 3 months thereafter. Prompt action in response to laboratory abnormalities, signs, or symptoms indicative of hepatic injury can mitigate, but not eliminate, the risk of serious hepatotoxicity Because of the risks of serious liver injury tolvaptan tablets are available only through a Risk Evaluation and Mitigation Strategy program called 

  • Because of the risks of serious liver injury tolvaptan tablets are available only through a Risk Evaluation and Mitigation Strategy program called the Tolvaptan for ADPKD Shared System REMS. Prescribers, Pharmacies and patients must enroll in the REMS program. 

CONTRAINDICATIONS:

  • History, signs or symptoms of significant liver impairment or injury. This contraindication does not apply to uncomplicated polycystic liver disease

  • Taking strong CYP3A inhibitors

  • With uncorrected abnormal blood sodium concentrations

  • Unable to sense or respond to thirst

  • Hypovolemia

  • Hypersensitivity (e.g., anaphylaxis, rash) to tolvaptan tablets or any component of the product

  • Uncorrected urinary outflow obstruction

  • Anuria

Serious Liver Injury: Tolvaptan tablets can cause serious and potentially fatal liver injury. Acute liver failure requiring liver transplantation has been reported in the post-marketing ADPKD experience. Discontinuation in response to laboratory abnormalities or signs or symptoms of liver injury (such as fatigue, anorexia, nausea, right upper abdominal discomfort, vomiting, fever, rash, pruritus, icterus, dark urine or jaundice) can reduce the risk of severe hepatotoxicity. To reduce the risk of significant or irreversible liver injury, assess ALT, AST and bilirubin prior to initiating tolvaptan tablets, at 2 weeks and 4 weeks after initiation, then monthly for 18 months and every 3 months thereafter.

Hypernatremia, Dehydration and Hypovolemia: Tolvaptan tablets therapy increases free water clearance which can lead to dehydration, hypovolemia and hypernatremia. Instruct patients to drink water when thirsty, and throughout the day and night if awake. Monitor for weight loss, tachycardia and hypotension because they may signal dehydration. Ensure abnormalities in sodium concentrations are corrected before initiating therapy. If serum sodium increases above normal or the patient becomes hypovolemic or dehydrated and fluid intake cannot be increased, suspend tolvaptan tablets until serum sodium, hydration status and volume status parameters are within the normal range.

Inhibitors of CYP3A: Concomitant use of tolvaptan tablets with drugs that are moderate or strong CYP3A inhibitors (e.g., ketoconazole, itraconazole, lopinavir/ritonavir, indinavir/ritonavir, ritonavir, and conivaptan) increases tolvaptan exposure. Use with strong CYP3A inhibitors is contraindicated; dose reduction of tolvaptan tablets are recommended for patients taking moderate CYP3A inhibitors. Patients should avoid grapefruit juice beverages while taking tolvaptan tablets.

 

Adverse Reactions: The most common reasons for discontinuation of Tolvaptan tablets in a randomized trial were polyuria, pollakiuria and nocturia. The most common treatment emergent adverse reactions in the same trial (>3% and >1.50/0 of placebo) were: thirst, dry mouth, fatigue, dizziness, dyspepsia, decrease appetite, abdominal distention, dry skin, hyperuricemia, and palpitations.

Other Drug Interactions:

  • Strong CYP3A Inducers: Co-administration with strong CYP3A inducers reduces exposure to tolvaptan tablets. Avoid concomitant use of tolvaptan tablets with strong CYP3A inducers

  • V2-Receptor Agonist: Tolvaptan interferes with the V2-agonist activity of desmopressin (dDAVP). Avoid concomitant use of tolvaptan tablets with a V2-agonist

Pregnancy and Lactation: Based on animal data, tolvaptan tablets may cause fetal harm. In general, tolvaptan tablets should be discontinued during pregnancy. Advise women not to breastfeed during treatment with tolvaptan tablets.

To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals, Inc. at 1-800-399-2561 or FDA at 1-800-FDA-1088 (www.fda.gov/medwatch).
