Medically reviewed by Drugs.com. Last updated on Aug 1, 2023.

2.1 Recommended Dosage

Adult Patients

The recommended dosage of VIJOICE in adult patients is 250 mg orally, once daily, administered as recommended [see Dosage and Administration (2.2)] until disease progression or unacceptable toxicity.

Pediatric Patients (2 to less than 18 years of age)

The recommended initial dosage of VIJOICE in pediatric patients is 50 mg orally, once daily, administered as recommended [see Dosage and Administration (2.2)] until disease progression or unacceptable toxicity.

Consider a dose increase to 125 mg once daily in pediatric patients ≥ 6 years old for response optimization (clinical/radiological) after 24 weeks of treatment with VIJOICE at 50 mg once daily. When a pediatric patient turns 18 years old, consider a gradual dose increase up to 250 mg. Recommended dose increases by age group are listed in Table 1.

*A recommended increased dose has not been established.
Patient age (years) Initial dose Dose increase
2 to < 6 50 mg Not applicable*
6 to < 18 50 mg 125 mg

2.2 Administration

Take VIJOICE with food at approximately the same time each day.

No tablet should be used if it is broken, cracked, or otherwise damaged at the time of opening the blister pack.

Swallow VIJOICE tablets whole. Do not split or chew.

If a dose of VIJOICE is missed, it can be taken with food within 9 hours after the time it is usually taken. After more than 9 hours, skip the dose for that day. The next day, take VIJOICE at the usual time.

If the patient vomits after taking the dose, advise the patient not to take an additional dose on that day, and to resume the dosing schedule the next day at the usual time.

Preparation and Administration for Patients Who Have Difficulty Swallowing Tablets

  • For patients who are not able to swallow tablets, administer VIJOICE as an oral suspension with food [see Clinical Pharmacology (12.3)].
    • Place VIJOICE tablets in a glass containing 2 to 4 ounces of water and let it stand for approximately 5 minutes. Make the suspension with water only.
    • Crush the tablets with a spoon and stir until an oral suspension is obtained.
    • Administer the oral suspension immediately after preparation. Discard the oral suspension if it is not administered within 60 minutes after preparation.
    • After administration of the oral suspension, add approximately 2 to 3 tablespoons of water to the same glass. Stir with the same spoon to re-suspend any remaining particles and administer the entire contents of the glass. Repeat if particles remain.

2.3 Dosage Modifications for Adverse Reactions

The recommended VIJOICE dose reductions for adverse reactions in adult and pediatric patients are listed in Table 2 and Table 3, respectively.

Hyperglycemia

Before initiating treatment with VIJOICE, test fasting plasma glucose (FPG), HbA1c, and optimize blood glucose. After initiating treatment with VIJOICE, monitor fasting glucose (FPG or fasting blood glucose) at least once every week for the first 2 weeks, then at least once every 4 weeks, and as clinically indicated. Monitor HbA1c every 3 months and as clinically indicated. In patients with risk factors for hyperglycemia, monitor fasting glucose more closely and as clinically indicated [see Warnings and Precautions (5.3)].
